Full textAbstract:
Current building energy modeling (BEM) tools lack the capability to inherently simulate the impacts of urban microclimates on building energy performance. While efforts have been made to integrate BEM with Urban Microclimate Modeling (UMM) tools, their ability to capture spatial and seasonal microclimate variations remains limited. This review critically evaluates existing urban microclimate-integrated BEM approaches and their effectiveness in modeling the complex interactions between urban form, microclimate, and building energy performance. Through an analysis of 94 research articles, the review first examines the influence of urban form on microclimates, followed by an assessment of how microclimatic conditions impact building energy use. Additionally, it evaluates conventional modeling frameworks employed in BEM tools and their limitations in representing dynamic microclimatic variations. The findings emphasize the non-linear heat exchange relationships between urban form and microclimate, typically modeled using computationally intensive Computational Fluid Dynamics (CFD)-based UMM tools. This review introduces a classification of heat exchange types: atmospheric heat exchange, involving air temperature, wind, and humidity, and non-atmospheric heat exchange, driven by radiative interactions with surrounding urban surfaces. The study further highlights that modifying standard weather files and heat transfer coefficients alone is insufficient for BEM tools to accurately capture near-surface microclimate variations. By identifying critical insights and research gaps, this review establishes a foundation for advancing next-generation urban microclimate-integrated BEM approaches, emphasizing the need for computationally efficient and dynamically responsive modeling techniques.

Abstract Despite the fact that the interrelationships between urban microclimates and energy demand have been recognised, there are not many processes that combine microclimatic boundary conditions to estimate energy consumption in parametric morphological investigations. Therefore, this paper will demonstrate a simple step-by-step methodology to incorporate the effect of urban microclimate on building cooling energy demand in semi-arid climatic areas. In this study, the combination of ENVI-met, Urban Weather Generator (UWG) and Rhino grasshopper are used to investigate the connection between microclimate and energy in the climatic environment of Kayseri. This coupling’s potential is investigated across compact high-rise, midrise and low-rise buildings, focusing on the cooling requirement on the hottest days. The comparative study shows how and to what extent urban geometry, building height in this case, contributes to modifying the magnitude of microclimate impact on building cooling performance.

This paper explores the influence of microclimates on changes in air temperature and the often-overlooked aspect of their effect on energy savings across varying microclimatic conditions. The study compares the cooling energy requirements of two identical single-story buildings in distinct microclimates: one characterized by concrete ground devoid of shade and the other featuring soil ground with tree shade. Climatic environmental data were collected over 15 days in the concrete-exposed field and shaded area beneath the trees to conduct the investigation. These datasets were input into EnergyPlus 9.6 to model the energy demands and consumption of buildings subject to the specified climatic conditions. The validation of the simulated model against actual energy demand data from a classroom building demonstrated agreement. The findings reveal notable differences in air temperature, with the shaded area experiencing temperatures 0.8°C to 8.0°C lower than the concrete-exposed monitoring location. The building in the tree-shaded microclimate exhibited a lower peak cooling load than its concrete-exposed counterpart, resulting in a 35% reduction in the electrical energy requirements for the air-conditioning system. The study recommends implementing 0.08-m polyurethane insulation for the building walls and roof to equalize the energy demand and consumption of the concrete-exposed building with that of its shaded counterpart. Furthermore, building design in shaded areas can maximize the window glass area while consuming less energy than buildings on concrete-exposed grounds. The study advocates leveraging the microclimate associated with surrounding buildings in the design process to enhance the overall energy savings.

To provide a more accurate prediction of building energy consumption, it is necessary to take into account the influence of the microclimate around a building establishing through the interaction with other buildings or the natural environment. This paper presents a method for the quantitative assessment of building performance under any given urban context by linking the urban microclimate model ENVI-met to the building energy simulation (BES) program EnergyPlus. The full microclimatic factors such as solar radiation, thermal radiation, outdoor air temperature, humidity, and wind speed have been considered in the proposed scheme. The method outlined in this paper could be useful for urban and building optimal design.

Modern machine learning (ML) technologies offer significant opportunities for optimizing microclimate management systems in buildings. In this article, we explore the potential application of ML methods for forecasting, adaptive control, and optimization of heating, ventilation, and air conditioning (HVAC) systems in buildings. We examine ML methods used for analyzing weather data, working hours, thermal needs, and user preferences to automatically optimize HVAC parameters. Additionally, we discuss the application of ML for detecting faults and preventing failures in microclimate systems, contributing to increased reliability and efficiency of building operations. Finally, we consider prospects for personalizing comfortable microclimates in buildings based on user preferences. Our analysis identifies the potential of ML for creating sustainable, energy-efficient, and comfortable buildings that meet modern requirements for microclimate management.

Full textAbstract:
Antique and cultural consumption spaces make a great contribution to urban vitality where numerous people walk, stay, and trade. However, how these people’s experiences and behaviours are affected by the microclimate of such spaces has not been studied till now. To address this gap, and using the concept of Post-occupancy Evaluation (POE) as a basis, our study investigated microclimate factors, subjective experiences, and spatiotemporal behaviour patterns in Panjiayuan Antique Market in Beijing, China. Using a mixed-methods approach comprising subjective questionnaires (n = 101), face-to-face interviews (n = 81), spatiotemporal behaviour mapping (n = 8455), and on-site observations, our results showed that microclimates impact people’s experiences and behaviours, with visibility and noise being the two primary impact factors. Most female visitors are more sensitive to the microclimate than male visitors. Furthermore, vendors in the Antique Market preferred to amend their nearby environments to increase the microclimate quality to offer a better experience to visitors around them. This study developed a comprehensive methodology that expands POE in relation to microclimatic factors in the context of cultural consumption spaces. These findings suggest that microclimates have different impacts on people’s experiences and behaviours in different spaces, which should be considered when designing and renewing urban antique markets in the future.

Full textAbstract:
In this work, we consider the indoor and outdoor microclimatic conditions and the influence of the building on their relationship. Microclimatic indexes are a useful tool to characterize microclimatic environments, and they can be used to compare indoor and outdoor microclimate conditions and to evaluate the influence of the building itself on the microclimate. The case study refers to the ancient building of San Panfilo church in Tornimparte (Italy), preserving an important cycle of frescoes by depicted by Saturnino Gatti from 1491 to 1494. The microclimatic conditions were measured during a dedicated campaign at several sites in the church and two sites outside: one in a near-building position and one in an open-air site. In order to characterize the indoor and outdoor microclimatic conditions, some statistical indexes were applied. The results show the comparison in microclimatic conditions in the different sites in the church and between indoor and outdoor environments, allowing for the detection of the influence of the building in the microclimatic conditions.

Full textAbstract:
Abstract The paper is aimed to illustrate how the study of the indoor microclimate, supported by the virtual simulation and by the knowledge of the historical evolutions of the building (managerial, usage and architectonical changes over the years), represents a preventive practice which allows to evaluate and predict the interactions between the object and the environment. To do that the authors present a case-study: room 33 in the Palace of Venaria Reale, in Turin, Italy. We have reproduced a virtual building model which presents the same indoor and outdoor microclimatic conditions of the original building. Moreover, we evaluated an alternative scenario that simulates the indoor microclimate of room 33 considering the HVAC systems continuously off. The comparison between the two virtual buildings allowed to estimate the impact of the HVAC system on the preventive conservation of the historical building, of the artefacts and of the occupants’ thermal comfort. Those simulations clarified which indoor microclimatic conditions could be guaranteed by the building itself, after the restoration project of the whole Palace started in 2001.

Full textAbstract:
The development of new urban areas in Beijing has alleviated overcrowding in old urban centers and has ample public spaces for recreational activities. However, these public spaces are not ideally designed and have not been as successful as expected. Few studies have investigated the ineffective use of these public spaces in terms of microclimatic and thermal comfort factors. Our study investigated microclimatic factors, the subjective assessment of thermal comfort, the intensity of human activities, and the spatial features of public spaces in conjunction with surrounding buildings in a mixed commercial and residential complex in the Fangshan District, Beijing. We used a mixed-methods approach comprising microclimate measurements, questionnaires (n = 150), spatiotemporal behavior mapping, and field measurements. Our results showed that the human perception of the microclimate is related to the exposure duration and other microclimatic factors. The perception of people who spend longer periods outdoors is often inconsistent with objectively measured thermal comfort values. Activity intensity (low, medium, and high) was also related to the duration of time spent outdoors. Microclimatic factors affect the number of people at different activity intensities and the trajectory of the activities. Different spatial features cause different microclimate formations and can directly influence the human subjective assessment of thermal comfort. This study uniquely links the microclimate to human perceptions, physical activities, and spatial features in service of redesigning public spaces. We developed a comprehensive methodology that expands the post-occupancy evaluation and proposes new urban public space designs that consider microclimates. This study also provides a new perspective for promoting physical activity by enhancing the thermal comfort of the environment to achieve physical and mental health goals.

Full textAbstract:
Microclimatic condition is a fundamental indicator for evaluating outdoor space livability and vitality. Research has shown that poorly designed building layouts can lead to discomfort; however, the mechanisms influencing outdoor microclimate based on residential building layout are unclear for high temperature and high humidity regions. This study explores the relationship between residential building layouts and the outdoor wind and thermal environment at the pedestrian level in Wuhan, a city renowned for high temperatures and high humidity. Six typical residential building layouts were simulated, using the ENVI-met numerical model, to determine the spatial distribution of wind speed and air temperature. The Universal Thermal Climate Index was adopted as a comprehensive index with which to assess spatial and diurnal variations in microclimates surrounding each building layout. Results showed that parallel building layouts formed a ventilation corridor that increased wind speeds by approximately 0.3 m/s. A staggered building layout, in line with the prevailing wind direction, facilitated airflow in the ventilation corridor and further increased wind speeds. Windward buildings blocked high-temperature airflows and reduced air temperatures by approximately 1 ℃ in parallel layouts, and 1.4 ℃ in enclosed layouts. However, the cooling effect of windward buildings on high-temperature airflow was weaker than the warming effect caused by the wind shadow effect and direct sunlight. Additionally, the performance of the thermal comfort of the enclosed type layout was significantly better, for most of the day, than the parallel type layout.

Full textAbstract:
Buildings account for over 35% of the energy demand in OECD countries, making them a prime target for improvement. (EIA 2011) To help building owners reduce energy usage, ratings systems such as LEED have been developed. A prerequisite for certification is the demonstration of energy efficiency through computer modeling; however, the complex nature of building energy simulations too often leads to errors of up to 30% (Turner and Frankel 2008). One source of significant error can be the assumptions made of environmental conditions, which are often simplified to speed up simulations. To demonstrate the significance of active microclimate modeling, a building energy model combined with a microclimate model has been created in RadTherm, a commercial CAE thermal solver. Simulations are run using Passive House construction in three types of environments, and demonstrate an increase in energy demand over an annual time scale when microclimatic components are included. The increase in demand is less than 1%, however the decrease in radiant heat losses are up to 30%. Using the same methodology with revisions to the building construction and urban geometry, a larger increase in energy demand is expected.

Full textAbstract:
Climate change projections estimate a rise of approximately 3 °C by the 2080‘s for most of the UK (under a medium emissions scenario at 50% probability level, 1961-1990 baseline). Warming is of particular concern for urban areas due to the issues of urban densification and the Urban Heat Island (UHI) effect. To combat warming, one adaptation strategy that has been suggested for urban areas is increasing the proportion of greenspace, such as parks, gardens, street tree plantings, and green roofs. While a number of studies have investigated the cooling effect of greenspace in terms of park size, proximity to a park, or area covered by tree canopy, little is yet known about the specific types of greenspace that contribute to its cooling effectiveness and how this relates to building energy demand. This thesis employs an interdisciplinary approach to model fine-scale changes to greenspace for a temperate northern UK city, linking the resulting microclimate changes to building energy consumption in commercial buildings. Using the urban microclimate model ENVI-met, two study areas (one urban one suburban) were modelled with seven different greenspace scenarios (a base case representing current field conditions, +5% new trees, +5% mature trees, +5% hedges, addition of a green roof on the largest building, changing all current greenspace to grass only, and changing all current greenspace to asphalt only) for a summer day in July 2010. The models were calibrated based on measured air temperature data and then analysed for microclimate changes due to each greenspace scenario. Both the modelled and measured microclimate data were then used to inform a series of building energy models using IES-VE 2012 for three commercial building types, estimating summer cooling and winter heating trade-offs due to greenspace effects. For the most effective scenario of adding 5% mature trees to the urban case study, the microclimate modelling estimates a maximum hourly air temperature reduction of nearly 0.7 °C at 5 pm and surface temperature reductions up to 1.7 °C at 3 pm. In the suburban case study, a 5% increase in mature deciduous trees can reduce mean hourly surface temperatures by 1 °C between 10 am and 5 pm, while the worst case scenario of replacing all current vegetation (20% of the study area) with asphalt results in increased air temperature of 3.2 °C at mid-day. The building energy modelling estimates a reduction of 2.7% in July chiller energy due to the combination of reduced UHI peak hours and eight additional trees (four on the north side and four on the south side) of a three-storey shallow plan building. These energy savings increase to 4.8% under a three-day period of peak UHI conditions. While winter boiler energy usage shows large reductions for a building in an urban location with a low proportion of greenspace (as compared to a suburban location), this benefit is marginal when analysed in terms of carbon trade-offs between summer cooling and winter heating requirements.

Full textAbstract:
With increasing concerns about the implications of climate change and urbanisation, there has been an increased public interest in the quality of urban open spaces in many countries because of its importance for daily people’s lives and urban environment. Recent studies in this field have shown that the microclimatic conditions are very important for people’s comfort in urban open spaces and, therefore, for the use of these spaces. Studying microclimate and thermal conditions in urban open spaces has been increased in the past years. The relationship between the microclimate, thermal comfort and the built urban form is still not understood very well. Further research in this aspect is needed. The courtyard is one of the open space types widely used in the countries of North Africa, Middle East and South Europe. The courtyard is often referred to in literature as a microclimate modifier. Because of this, many studies have been conducted in order to investigate its thermal environment. The majority of these studies dealt with the courtyard as a private space as a part of a building that can contribute to improve the indoor thermal conditions of the surrounding covered areas (its main function is to provide daylight and ventilation into the covered spaces). This study focuses on a particular type of courtyard. It deals with public enclosed courtyards which combine the features of the courtyards and public squares. This type of courtyard is not limited to provide only natural ventilation and natural daylight for the surrounding buildings, but it is mainly designed to offer a public place to perform a variety of activities for people such as social interactions, culture events, recreation, playing, business and many other activities. To the best of my knowledge, there have been no studies done on the microclimate and thermal comfort of courtyards with similar designs (function), particularly in hot dry regions. This study is conducted in Libya where the courtyard is the most common architectural pattern in its cities through all periods of the history. It is conducted in Libya where there is no published research on outdoor thermal comfort. This study investigated the microclimate, thermal comfort and the relationship with the built urban form of public enclosed courtyards in Tripoli city. The general purpose of this study was to develop a database of the thermal environment and subjective responses of people in existing public open spaces in a hot dry climate. The methodology used for this purpose was field studies. Two short-term field surveys were conducted in the two extreme seasons in Libya, one in the cool season day-time and the other one in the hot season day-time. A further field survey was performed during the hot season night-time, where no such study has been conducted in courtyards at this time in the past. In these field studies, extensive environmental measurements have been carried out in parallel to questionnaire surveys with the users of the selected case study sites. Six varied public enclosed courtyards representing three different architecture and urban-built forms of Tripoli city (old city, colonial city, and post-colonial city), were selected for the purpose of this study. The results showed that during both seasons, the microclimatic conditions in the studied courtyards were varied depending mainly on the amount of solar radiation received by their surfaces. Spatial characteristics (architectural form, geometry and surface materials and colours) had important roles in shaping the microclimates of the studied sites during both seasons. The results also showed that the distribution of thermal sensation votes, overall comfort votes and thermal preference votes were different for both seasons, as well as for the sites. Air temperature and then wind speed were found to be the most important determinants of people comfort. The findings of the study also revealed that summer night-time is considered to be of concern for urban thermal comfort in outdoor environments in Tripoli. In general, the findings confirmed a strong relationship between the built urban form (spatial characteristics of the sites), the microclimatic conditions and people’s comfort.

Full textAbstract:
In the past two decades, most regions of China have gone into the process of rapid urbanisation. In response to the enormous pressure due to the booming economy and fast growth in urban population, large-scale high-rise building group appeared and dominated the civil construction industry. However, these city-block scale estate projects have been criticised for the low-level thermal comfort in poorly designed indoor/outdoor spaces, and for its high energy consumption. Chengdu, a megacity in China, has been chosen as the research subject in consideration of its high urbanisation speed with a large number of estate projects at city-block scale and the deteriorating urban built environment. This study investigates the impact of multi-design variables on microclimates and the building energy performance of large-scale buildings through the application of GIS mapping and modelling. The relevant tools used in this study are ArcMap, ENVI-met, and SketchUp integrated with HTB2 and Virvil Plug-in. The study makes contributions to the research on microclimate and building energy consumption in four aspects. Firstly, it fills the gap in the outdoor thermal comfort and building energy consumption study at city-block scale in China by building up a theoretical framework of planning and design the high-rise building group in China. Secondly, design guidelines are established to improve both the microclimate performance and the building energy performance. Thirdly, a new approach to observe the local temperature of multi-scale subjects in a long-time period is concluded, which provides a new option of a method to analysis microclimate conditions for building scale research. Lastly, this study offers implications to relevant stakeholders for understanding the evaluation of low-carbon development at city-block scale. There are four phases in this study. In the first phase, document analysis is used to review the existing literature for discovering the research gaps, selecting potential measurements and technical tools, understanding the background and development history of the research subject. The second phase is the observation on microclimate condition. At this stage, on-site local urban heat island intensity is obtained by mapping the derived MODIS satellite data. In the third phase, multi-stage computational simulations will be used to calculate the microclimate performance and building energy performance accordingly. The former provides the predicted local meteorological data to be compared with data obtained from MODIS satellite, as well as the local air temperature of the target project sites for the adjusted simulation of the later which quantify the impact of variation in outdoor temperature. In the last phase, quantitative analysis and discussion are carried out for the results. Therefore, design guidelines of design strategy for mitigating building energy demand and optimising outdoor thermal comfort at city-block scale are concluded.

Ce travail de thèse aborde les liens complexes entre les processus physiques urbains, par le développement de modèles couplés pour tenir compte simultanément de la demande énergétique des bâtiments, les systèmes énergétiques individuels ou de quartier, et du microclimat urbain. L'échelle spatiale correspond aux quartiers urbains explicités géométriquement, et l’échelle temporelle est annuelle. Différentes stratégies de couplage ont été évaluées, pour leur capacité de représentation des effets thermiques, et des phénomènes couplés. Les schémas de couplages synchrones sont efficaces pour les interactions dynamiques entre bâtiments et microclimat. Néanmoins, ce couplage est sensible aux propriétés thermiques du bâtiment. La simplification de la canopée urbaine à un nœud de calcul entraîne une variation significative de la demande énergétique. Par ailleurs, le modèle développé a été utilisé pour évaluer les performances thermiques d'un quartier de La Rochelle. Le remplacement des climatiseurs individuels par un réseau urbain de froid élimine la contribution anthropique des bâtiments, et améliore le confort thermique extérieur, agissant comme une stratégie d'atténuation locale d’îlot de chaleur. Cependant, il entraîne une pénalité énergétique due aux pertes par le sol du réseau urbain. Cette pénalité énergétique est amplifiée lorsqu'une stratégie d'atténuation passive (matériaux froids) est mise en œuvre simultanément<br>This PhD work investigates the complex links between urban physical processes, through the development of coupled simulation platforms to account simultaneously for building energy demand, individual or district energy systems, and urban microclimate. The spatial and temporal scales correspond to urban neighborhoods under explicit geometries, and annual simulations respectively. Several coupling strategies have been evaluated, regarding thermal efficiency indicators, and the determination of the diversity of coupled phenomena. The synchronous coupling schemes can effectively assess the dynamical interactions between buildings and the local microclimate. Nevertheless, the coupling variable is sensitive to the thermal properties of the building. The simplification of the urban canopy layer to a single-node description reveals significant variability in building energy demand. Besides, the developed model has been employed to assess the thermal performance of an urban neighborhood in La Rochelle. The transition from local energy systems to the district energy network eliminates anthropogenic heat from buildings, and improves the outdoor thermal comfort conditions, acting as a local heat island mitigation strategy. However, it is associated with an energy penalty due to the ground losses of the piping circuit. This energy penalty is amplified when a passive mitigation strategy (cool materials) is implemented concurrently

Full textAbstract:
By 2050, the world’s population is expected to reach 9.7 billion, with over half living in urban settlements (United Nations, 2015). Planning and designing new urban developments and improving existing infrastructure will create or reshape urban landscapes and will carry significant implications for energy consumption, infrastructure costs, and the urban microclimate on a larger scale. Researchers and industry professionals must recognize how changes in land use affect the urban microclimate and, therefore, building energy consumption. Built environment and microclimate studies commonly involve modeling or experimenting with mass and energy exchanges between natural and the built environment. Current methods to quantify these exchanges include the isolated use of microclimate and building energy simulation tools. However, current urban planning and building design processes lack a holistic and seamless approach to quantifying all thermodynamic interactions between natural and built environments; nor is there a method for communicating and visualizing the simulated building energy data. This dissertation has developed a coupling method to quantify the effects of the urban microclimate on building energy consumption. The coupling method was tested on a medium-sized office building and applied to a design case, a redevelopment project in Pittsburgh, PA. Three distinct approaches were used. First, to develop the coupling method, a study was conducted to quantify the importance of accurate microclimate model initialization for achieving simulation results that represent measured data. This initialization study was conducted for 24 cases in the Pittsburgh climate. The initialization study developed a rule-based method for estimating the number of ENVI-met simulations needed to predict the microclimate for an annual period. Second, a coupling method was developed to quantify these microclimate effects on building energy consumption. The Center for Sustainable Landscapes (CSL) building was used as a test-case for this coupling method to measure improvement in predicting building heating and cooling energy consumption. Results show that the coupling method, more than the TMY3 weather data used for energy simulations, can improve building energy consumption predictions for the winter and summer months. Third, to demonstrate industry implications, the coupling method was applied to a design case, the Lower Hill District Redevelopment, Pittsburgh, PA. Comparing the decoupled energy model and TMY3 weather data revealed a high degree of variation in the heating and cooling energy consumption. Overall results reinforced the hypothesis that building surface level coupling is not essential if the energy model accounts for the microclimate effects. A Design Decision Support (DDS) method was also developed as a tool for project stakeholders to communicate high-fidelity simulated energy data.

Cette étude s’inscrit dans le cadre du projet "ANR-Villes Durables VegDUD : Rôle du végétal dans le développement urbain durable ; une approche par les enjeux liés à la climatologie, l’hydrologie, la maîtrise de l’énergie et les ambiances" (2010-2013). Elle traite de la modélisation et de l’expérimentation de toitures et de façades végétales, en vue de l’évaluation de leurs impacts hygrothermiques sur les bâtiments et sur les microclimats urbains. Un modèle physique a été développé pour décrire les mécanismes de transferts couplés de chaleur et de masse au sein de la paroi végétale. L’implémentation de ce modèle dans un code de simulation thermique dynamique permet de prédire l’impact de la végétalisation sur la performance énergétique des bâtiments. L’extension de cette démarche à l’échelle d’une rue-canyon permet d’inclure l’interaction microclimatique dans la simulation thermohydrique des bâtiments. Sur le plan expérimental, une maquette reconstituant une scène urbaine est mise en place pour étudier l’impact de différentes typologies de parois végétales dans plusieurs configurations microclimatiques. La confrontation des résultats expérimentaux et ceux issus de la modélisation numérique a été entreprise à l’échelle du système constitué du bâtiment et du microclimat urbain environnant. Pour cela, l’étude du comportement d’un bâtiment et d’une rue végétalisés par rapport au comportement du même bâtiment et d’une rue témoins a permis d’évaluer l’incidence des transferts thermiques, hygrométriques et radiatifs de la végétalisation. Ceci a permis d’entreprendre la validation des outils de prédiction numérique développés. Les résultats de l’étude montrent que les transferts thermiques et hydriques sont fortement couplés et que le comportement thermique des parois végétales est tributaire de l’état hydrique du substrat de culture. Pour l’été comme pour l’hiver, les simulations numériques et les données expérimentales montrent que la végétalisation permet d’améliorer la performance énergétique des bâtiments et de réduire les îlots de chaleur urbains<br>This study was conducted in the framework of the National Program "ANR-VegDUD Project : Role of vegetation in sustainable urban development, an approach related to climatology, hydrology, energy management and environments" (2010 -2013). It deals with the experimental and numerical modeling of green roofs and green facades to evaluate their thermohydric effects on buildings and urban microclimates. A physical model describing the thermal and water transfer mechanisms within the vegetated building envelopes has been developed. The model’s program has been implemented in a building simulation program. Using this tool, we are able to predict the impact of green roofs and green facades on building energy performance. This approach is extended to the street canyon in order to assess the microclimatic interaction in building simulation. An experimental mockup modeling an urban scene at reduced scale is designed to study the impact of different types of green roofs and walls. The comparison of the measurements carried out on vegetated buildings and streets with the reference highlights the hygrothermal and radiative impacts of vegetated buildings envelopes. In addition, these experimental data are used to verify and validate the reliability of developed tools. The results show that thermal and water transfers are strongly coupled. Hence, the thermal behavior of green roofs and green walls depend on the water availability within the growing medium. In summer and winter, measurements and numerical simulations show that green envelopes improve the energy efficiency of buildings and reduce the urban heat island

Full textAbstract:
Den befolkningstillväxt som sker idag skapar utmaningar för det befintliga bostadsbeståndet och vår bostadsförsörjning. För att klara tillväxten bygger vi våra städer tätare och högre vilket skapar både möjligheter och utmaningar. Ett sätt att effektivisera redan exploaterad mark kan vara att genom vertikal förtätning skapa fler bostäder på befintlig bebyggelse. Syftet med detta examensarbete är att belysa hur våningspåbyggnad i en urban miljö kan gestaltas och vilken påverkan den kan ha på mikroklimatet. För att undersöka huruvida det är lämpligt att förtäta ett utvalt objekt genomfördes en lämplighetsanalys baserat på ett tidigare examensarbete av Larsheim (2007), vilken behandlar inventering av fastighetsbestånd för vertikal förtätning. Denna metod har bearbetats i samråd med planarkitekt på Luleå kommun innan den tillämpades på det utvalda förtätningsobjektet vilket renderade i att byggnaden kunde anses lämplig att förtäta på. För att beskriva byggnaden och dess närområdes arkitektoniska karaktär utfördes en analys enligt Thiis-Evensen (1994) metod. Med hjälp av Pena och Parshalls (2001) metod ”Problem seeking” syntetiserades den arkitektoniska karaktärsanalysen tillsammans med förtätningsteori och teori om mikroklimat. Syntesen gav ett förslag till gestaltningsprogram för hur våningspåbyggnaden skulle kunna gestaltas. Examensarbetet resulterade i ett gestaltningsförslag se del 6. Gestaltningsförslaget. Påbyggnaden består av 45 lägenheter som är placerad ovanpå ett befintligt parkeringshus i Luleå, bostäderna är fördelade på tre plan vilka vilar på en förlängd pelarstomme. Påbyggnaden öppnar upp för nya möjligheter till ett attraktivt boende i innerstaden och har dessutom kvalitativa grönytor för lek och socialt umgänge samt odlingsbara ytor i ett växthus. I syfte att positivt kunna påverka de förändringar som kan ske då stadens tak bebyggs har mikroklimatsanalyser utförts utifrån faktorerna sol, vind, luftkvalitet, ljud, snö samt fenomenet ”Urban heat islands”. Analyserna som utförts har påverkat val av form och material för det i del 6. presenterade gestaltningsförslaget. Det presenterade gestaltningsförslaget bör i ytterligare steg undersökas av annan part då detta inte kunnat utföras under examensarbetets gång. Den lämplighetsanalys som testats i detta examensarbete bör valideras och utformas i närmre samarbete med intressenter och kommun för att säkerställa att rätt kriterier och tillvägagångssätt används då lämplighet för påbyggnad ska bestämmas.<br>The current ongoing population growth creates challenges for the existing housing stock and our housing supply. To handle this population growth, our cities are being constructed higher and more densely, which creates new opportunities and challenges. One way to make use of the already exploited land could be by using the principle of vertical densification to raise the existing building height and thereby being able to create new housing opportunities. The purpose of this master thesis is to illustrate how a rooftop extension could be configured into an urban environment and what impacts this configuration might have on the microclimate for the subjected area. To study the eligibility for a densification on the selected object, a method of eligibility analysis was carried out. The method used is based on a previous degree project by Larsheim (2007), which deals with stocktaking and assessing property stocks for vertical densification. The redesigned method was before being used on the selected object for densification drafted in consultation with planning architect at Luleå municipality. The final usage of the method resulted in the building being considered suitable for densification. A site analysis was conducted with regards to the existing building and its vicinity with a method written by Thiis-Evensen (1994). The method is focused on describing the architectural nature of the site. This analysis, together with the selected theory of densification and microclimate, was synthesized using Pena and Parshall's (2001) method "Problem seeking", which rendered a suggestion of a program for how the building could be configured. This master thesis resulted in a design proposal for a rooftop extension, see part 6. Gestaltningsförslaget. The extension is located on top of an existing multistory car park building in the centre of Luleå. The rooftop extension contains 45 apartments and consists of three elevated planes that resides on an extended pillar construction. A large green open area on the inner courtyard unlocks new opportunities for an attractive accommodation in the inner city. It also give the residents a room for social play and interaction as well as the opportunity to use cultivable surfaces in a new greenhouse. A microclimate analysis was carried out based on solar, wind, air quality, sound, snow, and the phenomenon of Urban heat islands in order to positively change the impact that might occur when the city’s rooftops are being extended. The analysis carried out influenced the selection of form and material in the design stage for the design proposal presented in part 6. The design proposal presented should be further investigated by another party. The eligibility analysis conducted in this master thesis should be validated and designed in close collaboration with stakeholders and municipalities to ensure that the correct criteria and approaches are being used when the eligibility of the rooftop extension is to be determined.

Concilier patrimoine et amélioration de la performance énergétique du bâti ancien est un défi pour de nombreux centres historiques. La Communauté d’Agglomération du Grand Cahors, qui finance ce travail de thèse à travers une convention CIFRE, a souhaité s’attaquer à cette problématique en valorisant des isolants bio-sourcés. Le choix du matériau et du système d’isolation sont essentiels car ils influencent à la fois la performance hygrothermique de la paroi, la qualité de l’air intérieur, le coût et l’empreinte carbone de la rénovation. Dans cette étude, nous nous sommes focalisé sur la performance hygrothermique de la paroi afin d’assurer que la mise en place d’une isolation par l’intérieur ne soit pas source de dégradations futures de la paroi. Pour cela, nous avons confronté différents outils et méthodes tels que la caractérisation physique des matériaux, une instrumentation in-situ dans deux appartements du centre ancien de Cahors et des simulations hygrothermiques alliant différents outils numériques<br>Improving the energy efficiency of buildings is essential to reduce greenhouse gas emissions and mitigate against climate change. Historic dwellings represent a large part of the French building stock that needs to be refurbished. In the city center of Cahors, France, the old medieval dwellings are considered as valuable cultural heritage and internal insulation is often the only insulation technique that can be used when the architectural value of the exterior façade is to be preserved. This PhD thesis, funded by a CIFRE agreement with the Communauté d’Agglomération du Grand Cahors, studied the suitability of bio-based materials for the internal insulation of historical dwellings in urban area. The selection of the insulation material and the system is crucial because of its impact on the hygrothermal performance of the wall, the indoor air quality, the financial cost, and the carbon footprint of the refurbishment solution. In this study we focused on the hygrothermal performance of the walls to provide a reliable risk assessment in order to avoid hygrothermal failure. Due to the complexity of the problem and the lack of needed data, we ran a multi-scale study including both experimental (laboratory characterisation and building monitoring) and numerical modelling methods

Full textAbstract:
AbstractIn the past, urban climate problems caused by rapid urbanization, mainly urban heat island effect, affected people's daily life; under the background of new urbanization, people pay more attention to climate perception on human scale, and explore green and comfortable urban environment construction path and economic and effective urban cooling strategy. At present, the study of urban planning pays attention to macroscopic land use layout or microscopic landscape design but lacks the discussion on the influence of architectural layout on microclimate construction. Based on Grasshopper software, this paper constructs a microclimate analysis model of urban block scale and simulates the influence of different architectural layouts on urban microclimate in urban blocks by using control variable method. Through analysis, it is concluded that the microclimate of urban blocks is affected by building height, density, overhead rate of the first floor and building layout. Finally, the index optimization of urban design is proposed to improve the microclimate of blocks in urban planning and promote the construction of climate-adapted cities.

Full textAbstract:
AbstractUrban vulnerability has many facets. Among these, urban texture and plot pattern, building massing and density, greatly affect the microclimate. Thence, redefining urban regeneration design criteria for climate neutrality is crucial, including environmental factors in the design process at different scales. In the light of climate change, despite this urgent call, adaptive design approaches useful to assess trade-offs between urban regeneration scenarios and microclimate quality are lacking. This paper introduces a novel digital design workflow that integrates climate quality and associated indicators in urban and building design, adopting a cross-scale approach. The main goal is to increase the resilience of the built environment in the foresight of future scenarios, by promoting climate-sensitive design solutions. Environmental performances were analysed using digital tools and implemented in a design workflow, allowing urban microclimate analysis. Performance metrics were calculated using Urban Weather Generator and Energy Plus. With the former tool a climate performance comparative study has been run in different scenarios, by varying morphological parameters and computing the intensity of the Urban Heat Island. While, Energy Plus was used to simulate the impact of building form and UHI on building energy demand, highlighting the interdependence of different design scales and addressing optimal building performance. The results provide additional levels of knowledge, both in terms of analysis and design scenario evaluation: urban metrics and climate impacts, building form and envelope design, adaptation solutions. This workflow is tested and a scenario suitability for the Mediterranean city is shown, exploiting the research-by-design transformations of 22@ Innovation District of Barcelona. The paper highlights the correlation between microclimate and design solutions and lays the foundations for a climate/design cross-talk to help policymakers and practitioners achieve urban climate adaptation goals.

Full textAbstract:
This article deals with the issue of the indoor environment in terms of optimal conditions of thermal comfort and the satisfactory quality of indoor air. A weekly measurement of the parameters of the indoor environment was carried out in the building of the day rehabilitation centre in order to verify the state of the indoor environment, to determine the processes that create the indoor environment and to define the factors that affect the resulting state of the indoor microclimate. One of the important factors is air quality, where the main factor that influences the indoor environment is the concentration of carbon dioxide, whose value affects the biological functions of the human organism. The analysis of the measured parameters found that the concentration of carbon dioxide in the monitored indoor space is not, as expected, the riskiest factor that may be the cause of dissatisfaction with the indoor microclimate.

Full textAbstract:
Urban areas have higher temperatures than the surrounding suburban/rural areas, a phenomenon known as the Urban Heat Island (UHI). There is a great interest in creating a healthy and comfortable environment for the growing number of urban dwellers to live in, therefore different methods of combating and diminishing the urban heat island are being studied. One such method is to reduce the energy contribution of buildings to the formation of the urban heat island. In this paper we analyzed the effect of building envelopment, both by seasonal monitoring of surface temperatures using the thermal camera at different time intervals, and by numerical simulations of air temperature at different levels in the atmosphere, using ENVI-met, a three-dimensional non-hydrostatic microclimatic model. The data sets resulting from the monitoring of the surface temperature with the thermal camera showed that the temperature recorded at the surface is lower for the enveloped buildings than for the non-enveloped buildings, during the night but also during the day, less at noon. The numerical simulations were based on two scenarios: i) buildings with non-enveloped walls and ii) the same buildings but with enveloped walls, after running the scenarios for enveloped and non-enveloped buildings. The results showed that following the enveloping process the air temperature in the areas between the buildings is lower for the enveloped buildings, at different heights, both during the night and during the day.

Full textAbstract:
Cities' morphologies determine the urban microclimate. The thermal conditions may differ according to the distance from the ground. For instance, air velocity and solar incidence tend to be higher as the height increases due to the decrease of obstacles to wind and radiation. This work discusses the gradient of vertical air temperatures in a high-rise building area. In winter and spring, measurements in the field at two heights on the same building occurred in the coastal Brazilian city of Balneário Camboriú. The air temperature was generally higher during the daytime at the highest point than the near ground one, especially in clear sky conditions, and lower during nighttime. As the sky view factor increases with height, the shading obstacles decrease, leading to generally higher solar access and a higher heat released through longwave radiation to the sky. Also, the studied area was modelled in ENVI-met and compared to field measurements. Simulation's results in the vertical profile showed the opposite behaviour than the field observations. Especially in high-density cities, understanding the vertical microclimate profile may guide the development of urban climate improvement strategies.
