Is the window just one of the most commonplace elements of buildings? Is it a simple void or aperture in the external wall? It has to provide optical connection between interior and exterior admits light and air; offer a view, ensuring mental comfort in the interior. However, it is the most exposed element of the building envelope. Construction and building physic properties of windows significantly impact formation of optimal indoor climate and they are crucially involved in the energy loss of the object. Nevertheless, architectural expression is one of the most important functions of the window. As history of architecture shows, window is one of the key architectural components of a building.

The use of rapidly renewable raw materials in the building industry is seen as very promising with regard not only to the environmental issues but also to its economic aspects. A number of producers, not only in this country, have been trying to replace fine construction materials with secondary raw materials or rapidly renewable ones. As an example, technical hemp is a very promising material due to its good mechanical and thermal insulation characteristics. One of the possibilities is its use as filling component for non-constructional filling materials. Combining binders on the basis of non-hydraulic lime with hemp chaff yields a range of new construction materials. These products offer excellent work characteristics for permanent, environmentally sustainable buildings. These products as a whole form a natural composite construction material that can be used to build insulation walls, floor and roof insulation layers, and to obtain excellent heat and acoustic characteristics of buildings.

Full textAbstract:
Due to an increasing request for ecological building constructions, in particular straw bale buildings, a research in this regard has been performed at the Vienna University of Technology. Straw bale construction is a new rediscovered building technology, which is an alternative to conventional construction technologies. The aim of this study is caring out of hygro-thermal simulation of a straw bale wall construction to design as efficiently as possible straw bale house. The choose of other construction elements for a thermal analysis (appropriate wall, roof and a base plate construction), was based on an extensive literature researche. For the examination of the building a timber frame construction has been selected. The straw bales in this construction were plastered inside with clay plaster and externally with a combination of lime and clay plaster. The roof structure was designed as a green roof and insulated with straw bales. The base plate was also insulated with straw bales. To check the thermal behavior of the structures described above were thermal bridges calculated using a FEM program. The hygrothermal behavior was calculated with HAM4D building physic software, developed on the department for Buildings Physics and Sound Protection on Vienna University of Technology. Ecological and economic evaluation of straw bale construction was carried out with reference to the data from the literature. The performed thermal (with COMSOL) and the first hygrothermal calculations (with HAM4D Software) have demonstrated a very favorable performance of the proposed building components. The achieved low U-values of the components allow the construction of passive houses. The use of self-build-service in the construction process can reduce construction costs significantly. The use of ecological materials such as: straw, clay and wood allows a low cost recycling of building materials.

Culture changes in community will affect its social structure (Hirsan, 2005). Additionally, Auliya (2009) said that cultural changes also determine the elements of residential. Social culture changes not only will influence the order of settlement space but also the concept of spatial structure. Sukarara Village as one of tourism destination for handicraft weaving in Lombok Tengah Regency has changed, especially in settlement physic. There was six traditional house type but remain four types, which mixed with modern buildings. Physically, settlement building seen using modern element; however, the community has strong belief on cosmologic value, which implemented in settled rules and tradition. This study is to find out the connectedness in the phenomena between developments of an increasingly modern society with rules and tradition belief to settle; how integration and pattern formed in Sukarara Village. This research used qualitative inductive method, which approached with phenomenology technique using in-depth interview in Sukarara Vilage. The result shows that there are four kinds of integration and pattern concept in Sukarara Village: (1) bale beleq as spatial shaping : connectedness history; (2) nature as sacred clue to settle: connectedness community culture; (3) various type and building shape as settlement pattern transformation: connectedness spatial physic; (4) farming and weaving as living basic: connectedness of source of life. The four concepts change pattern orientation in traditional settlement, which is adapted by community along live activity, <em>nyensek</em> and <em>begawe</em>.

Full textAbstract:
The goal of this study is to find a practicable way to recycle cuttlebone waste in the production of lime. It was studied the behavior of calcium oxide obtained from the calcination of this waste at 900, 1000 and 1100 ºC and, after wet slaking, the produced lime was characterized. All the results were compared to calcium oxide or to hydrated lime obtained from commercial limestone. According to the slaking results, the waste and the limestone calcined at 1000 ºC achieved the R4 (around 13 min to reach 60 ºC) and R5 (60 ºC in 25 s) reactivity class, respectively. Changing the calcination temperature to 900 or 1100 ºC did not promote an increase in the reactivity of the calcined waste. Although less reactive than the calcined limestone, the calcined cuttlebone can be transformed without significant constraint into building lime, since this construction material fulfills the relevant physic-chemical standard specifications.

As pointed out in this paper that, for a common building material, it is relatively difficult to judge its green degree in comparison with that for a special function material because the judgment factors are comprehensive. The relevant factors which affect the greenness index such as physic expenditure, pollution, economic are analyzed and all influential factors are discussed. For the common building materials, their different inter-restrain factors are divided in administrative level and the weight of factors is determined according to the AHP theory. Meanwhile, the assessment scale and criteria for the factors, and the grading standard for the material green degrees are given in the paper. Based on the fuzzy comprehensive evaluation theory, a green degree evaluation model is established. Finally, the reasonability of the model is testified with the instances introduced in the paper.

The research of coupled heat and moisture transfer is a complex process, which is the fundamental of decreasing building energy consumption; improving IAQ and increasing the durability of building envelop. CHAMPS-BES software is an outcome of a joint effort between Building Energy and Environmental Systems Laboratory (BEESL) and Institute for Building Climatology (IBK). This software is used for analysis and prediction of hygrothermal performance of building enclosures; impact of outdoor climate and pollution on indoor environment; impact of VOC emissions from building materials and indoor furnishings on indoor air quality. This paper introduces the basic mathematic and physic model, boundary condition, climate condition etc, and analyzes the coupled heat and moisture transfer through common structure of building envelop in Shanghai. According to simulation results, main materials of the wall in ITIS have to endure larger range of temperature than ETIS that leads to the life of materials shorter. Capillary condensation occurs on inside surface of the wall easily when RH is larger than 70% and the minimum pore size of finish layer is around 5×10-9m avoiding capillary condensation and mold growth

Purpose – The purpose of this paper is to verify the applicability and efficiency of two statistical methods to obtain sustainable targets of temperature and relative humidity in historic buildings located in temperate climates. Design/methodology/approach – The data recorded along one year in a non-heated historic building in Lisbon (Portugal) was analysed with the two methodologies, EN 15757 and FCT-UNL. To evaluate their adequacy it was calculated the performance index for each target and it was verified the mechanical and biological degradation risks. Findings – While the use of the two approaches is suitable for temperate climates, there is a higher efficiency of the FCT-UNL methodology, allowing a better response for the three parameters in evaluation. Research limitations/implications – Despite the better results obtained, the FCT-UNL methodology was only tested for one city; therefore the application to other situations may be required to obtain more robust conclusions. Practical implications – The effectiveness of the FCT-UNL methodology to obtain sustainable climate targets can lead to important energy conservation in historic buildings and to contribute for the change of old approaches in the preventive conservation area. Originality/value – This paper provides a comparison between two recent methods. The results can lead to some advances in the science of preventive conservation, interesting to conservators and building physic scientists.

Hydraulic support tester is the key equipment to measure the safety performance and technical performance of the hydraulic support. As an integral part of hydraulic support tester, synchronized loading system bears much load and eccentric load, needs high synchronization precision, and exits mechanical-hydraulic coupling. For these characteristics, building a synchronous loading system platform model, carrying on force analysis of the platform, and then getting four-cylinder pressure at different heights of the loading course are necessary. This research constructs a synchronous control circuit for hydraulic loading system using multi-physic modeling and simulation software—AMESim; simulation is carried out to optimize parameters of PID controllers in order to reduce the four-cylinder position synchronization error. As a conclusion, simulation results validate that appropriate solutions improve the precision and also demonstrate that the designed control system is suit for the synchronization control of the four-cylinder.

Full textAbstract:
The heat of the earth is provided by solar radiation. A change in the angle of solar radiation and the surface of the earth causes changes in the ambient temperature. Sometimes, these changes reduce climatic comfort of human beings. Climatic comfort is established when there is a balance between excreted and absorbed temperatures of the skin of the body. Orientation and extension rates of physics of squares relative to the geographical north influence the amount of received direct sunlight in different months. Relevant studies show that the squares of the city of Yazd reduce the climatic comfort of its citizens; moreover, the physics of Yazd's squares apply various extension rates, which led to high building costs to citizens and relevant organizations. This study, by using the correlation method and R software, measures different orientation and extension rates of physics of squares in Yazd. It analyzes two models with orientation and physical extension as variables and evaluates the shade and sunlight in the space. The results reveal significant differences between desirable and undesirable options. Considering the climatic comfort of space users and residents at the same time, a rectangle with an extension ratio of one to several and the north-south orientation, making the lowest facade face the south, is the most appropriate physic for city squares.

Full textAbstract:
From the oldest times, man has been using wood as prime material in building houses, as well as manufacturing tools needed around the house. Romanians, being strongly connected with the forests, they have been observing the way some wooden species are behaving to different stimulus and so being able to choose the species with the highest resistance from the durability, physic -mechanic characteristics, visual aspect and industrial prime matter points of view. An "ecological" house, for a simple man, represents the manual handcrafting of the wood and also using it in various domains such as building shelters, tools and other useful items that are a day by day necessity around the house. A "modern" house is an upgrade of what massive wood has meant in construction, tools and objects are using new crafting and finishing techniques, which are well superior to those already known by elder people. The construction of a "modern" house also involves the use of new materials that can meet people's needs; and so the used wood proportion is decreasing, placing itself in a secondary plan and increasingly used in combination with other materials. The environment has been, is and will always be a witness of all civilizations and everything that means evolution and modernization, knowledge and development; the forests, , in our opinion, always occupying the most precious place in human life.

Full textAbstract:
Historic building restoration and renovation requires sensitivity to the cultural heritage, historic value, and sustainability (i.e., building physics, energy efficiency, and comfort) goals of the project. Energy-efficient ventilation such as demand-controlled ventilation and heat recovery ventilation can contribute to the aforementioned goals, if ventilation concepts and airflow distribution are planned and realized in a minimally invasive way. Compared to new buildings, the building physics of historic buildings are more complicated in terms of hygrothermal performance. In particular, if internal insulation is applied, dehumidification is needed for robust and risk-free future use, while maintaining the building’s cultural value. As each ventilation system has to be chosen and adapted individually to the specific building, the selection of the appropriate system type is not an easy task. For this reason, there is a need for a scientifically valid, systematic approach to pair appropriate ventilation system and airflow distribution solutions with historical buildings. This paper provides an overview of the interrelationships between heritage conservation and the need for ventilation in energy-efficient buildings, regarding building physics and indoor environmental quality. Furthermore, a systematic approach based on assessment criteria in terms of heritage significance of the building, building physics (hygrothermal performance), and building services (energy efficiency, indoor air quality, and comfort rating) according to the standard EN 16883:2017 are applied.

Full textAbstract:
The development of methods for the calculating reinforced concrete structures covers a wide range of issues, including the expansion of the application of new innovative materials such as concrete and reinforcement. For usage in the practice of modern construction of multilayer structures made of concrete with different physic-mechanical characteristics, it is compulsory to conduct numerical studies of the stress-strain state of these structures under different types of loading. This article presents an analysis of the influence of the relations between the initial elastic modulus of the outer and middle layers for the stress-strain state and the deflection of three-layer reinforced concrete structures using the finite element method in the program ANSYS Mechanical. Numerical modeling allows comparing the obtained results and building theoretical dependences in a wide range of specified parameters for the construction of sections of multilayer reinforced concrete elements. The obtained scientific results enable to determine rational parameters for modeling various structural solutions of multilayer reinforced concrete structures. This would limit the number of actual test samples, increasing the efficiency of the experiment.

Landslide is the third largest disaster in Indonesia, including in Probolinggo. Approximately 50% of Probolinggo regency area is a potential landslide region. This area is located in the southern part of Probolinggo regency with hilly terrain and slopes. The number of landslide events in 2015-2016 is recorded 21 events. Potential landslide hazard was analyzed by SINMAP (Stability Index Mapping) method using physic condition, slope, digital elevation model, and rainfall. The risk level of landslide hazard is derived from the crosstab between landslide hazard potential and vulnerability index covering exposure aspect, sensitivity, and adaptive capacity with variables consisting of population density, livelihood, the proportion of the vulnerable population, building quality, and the number of poor households. The high risk of landslide hazard in Probolinggo regency is found in four districts of Lumbang, Pakuniran, and Kotaanyar sub-district. Potential landslide areas are spread in the south of Probolinggo Regency, especially in Krucil subdistrict with 15-40 % slopes. Based on the spread of landslide location, as many as 81% of landslide locations occur in high and medium landslide potential areas.

The measurement of cutting forces permits building of physic-mechanical cutting models for a better understanding of the phenomena observed during cutting. It also permits the design and optimization of processes, machines, tools, and wood preparation. Optimization of cutting conditions of wood-based materials can decrease the cutting forces, which directly relates to the energy consumption and surface quality. The sawdust analysis may serve for analysis of cutting kinematics and occupational health risk. The aim of the study was to estimate the correlation between the feed rate and both feed force and sawdust particle size produced during particleboard circular sawing. A saw machine type K700 was used in experiments. There were three feed rates of 12, 18, and 24 m/min executed by a horizontal pneumatic actuator fixed to the sliding side table of the saw machine. Based on the results of the experiments, a positive correlation was observed between the feed rate in a circular sawing process and feed forces and an unexpected particle size distribution depending on the feed rate.

Educational buildings comprise a considerable portion of the public non-residential building stock. In order to assess the influence of the main parameters involved in the design and possible retrofitting of educational buildings, a secondary school building was selected and investigated with respect to its thermal behavior using EnergyPlus. Designing factors, as well as construction and operational solutions are examined individually and compared with each other, in order to find the best solution for either designing from scratch or retrofitting an educational building. In particular, the orientation of the openings, the thermal mass of the building and alternative insulation solutions, such as the thickness and location of the insulation layers in the building components, are compared. The simulation confirms, that the best orientation for educational buildings is the one in which their long axis coincides with the east-west one. The internally insulated building requires less energy but the difference is too small to be considered cost efficient. Regarding the heating system, from the alternative scenarios examined a one or two hour morning reheat strategy reduces the needed installed capacity for heating by up to 10%.

<p class="Abstract"><em>Suburbanization is a process to shape built areas as an impact urban development expansion (Wiratmaja, 2002:33). The real form of suburbanization is shift settlements activity towards suburban area. Therefore, many new development settlements are made to accommodate city core inhabitants at this time. Pedalangan Subdistrict and Bulusan which are part of Banyumanik District also Tembalang has been filled by new formal settlements such as Graha Estetika, Graha Sapta Asri, Grand Tembalang Regency, Villa Tembalang, and Korpri. Whereas, urban settlements in Pedalangan Subdistrict also Bulusan is not only consist of estate that is part of formal settlements but also Kampong which is a part of informal settlements. Mostly, new developments of formal settlements build nearby informal settlements that have been there first. These things have a potential thing to emerge disparity related social, economic, cultural, physical, and spatial aspect. One of the most spatial impacts that will appear is the land price differentiation between formal and informal settlements. Based on that phenomenon is formulated statement research “There was land price differentiation as an impact of mix urban settlements between formal and informal settlements in suburban area.” This research aims to identify land price differentiation that occurred as an impact of mix urban settlements in suburban area. In order to achieve that purpose, the process of identification and analysis need to carry on towards factors that could affect the land price such as land physic characteristic, accessibility, facility and infrastructure availability, ownership status, and environmental quality. This research will use quantitative descriptive analysis with descriptive statistics based on the results of questionnaires and observation. Based on findings, that indicate there are only two factors that can be land price differentiation between formal and informal settlements is the ease of accessibility and facility and infrastructure availability. The land physic characteristic, ownership status, and environmental quality can not to identify land price differentiation because of these characteristics of each these factors are almost equally between formal and informal settlements. Based on the results of the study findings it can be concluded that there are land price differentiation between formal and informal settlements caused by mix urban settlements. It also need a form of problem solve such as zoning regulation, land conversion regulation, land transaction regulation, land taxation, and regulation of new building that aims to control development of suburban areas to be more focused by considering the integration process physical, social, and economic community.</em></p><em></em>

Accurate short-term forecasts of building energy consumption are necessary for profitable demand response. Short-term forecasting methods can be roughly classified into physics-based modelling and data-based modelling. Both of these approaches have their advantages and disadvantages and it would be therefore ideal to combine them. This paper proposes a novel approach that allows us to combine the best parts of physics-based modelling and machine learning while avoiding many of their drawbacks. A key idea in the approach is to provide a variety of building parameters as input for an Artificial Neural Network (ANN) and train the model with data from a large group of simulated buildings. The hypothesis is that this forces the ANN model to learn the underlying simulation model-based physics, and thus enables the ANN model to be used in place of the simulator. The advantages of this type of model is the combination of robustness and accuracy from a high-detail physics-based model with the inference speed, ease of deployment, and support for gradient based optimization provided by the ANN model. To evaluate the approach, an ANN model was developed and trained with simulated data from 900–11,700 buildings, including equal distribution of office buildings, apartment buildings, and detached houses. The performance of the ANN model was evaluated with a test set consisting of 60 buildings (20 buildings for each category). The normalized root mean square errors (NRMSE) were on average 0.050, 0.026, 0.052 for apartment buildings, office buildings, and detached houses, respectively. The results show that the model was able to approximate the simulator with good accuracy also outside of the training data distribution and generalize to new buildings in new geographical locations without any building specific heat demand data.

Abstract. Given the current challenges in flood risk management and vulnerability assessment of buildings exposed to flood hazards, this study presents three-dimensional numerical modelling of torrential floods and its interaction with buildings. By means of a case study application, the FLOW-3D software is applied to the lower reach of the Rio Vallarsa torrent in the village of Laives (Italy). A single-family house on the flood plain is therefore considered in detail. It is exposed to a 300-year flood hydrograph. Different building representation scenarios, including an entire impervious building envelope and the assumption of fully permeable doors, light shafts and windows, are analysed. The modelling results give insight into the flooding process of the building's interior, the impacting hydrodynamic forces on the exterior and interior walls, and further, they quantify the impact of the flooding of a building on the flow field on the surrounding flood plain. The presented study contributes to the development of a comprehensive physics-based vulnerability assessment framework. For pure water floods, this study presents the possibilities and limits of advanced numerical modelling techniques within flood risk management and, thereby, the planning of local structural protection measures.

Full textAbstract:
Buildings contribute to nearly 30% of global carbon dioxide emissions, making a significant impact on climate change. Despite advanced design methods, such as those based on dynamic simulation tools, a significant discrepancy exists between designed and actual performance. This so-called performance gap occurs as a result of many factors, including the discrepancies between theoretical properties of building materials and properties of the same materials in buildings in use, reflected in the physics properties of the entire building. There are several different ways in which building physics properties and the underlying properties of materials can be established: a co-heating test, which measures the overall heat loss coefficient of the building; a dynamic heating test, which, in addition to the overall heat loss coefficient, also measures the effective thermal capacitance and the time constant of the building; and a simulation of the dynamic heating test with a calibrated simulation model, which establishes the same three properties in a non-disruptive way in comparison with the actual physical tests. This article introduces a method of measuring building physics properties through actual and simulated dynamic heating tests. It gives insights into the properties of building materials in use and it documents significant discrepancies between theoretical and measured properties. It introduces a quality assurance method for building construction and retrofit projects, and it explains the application of results on energy efficiency improvements in building design and control. It calls for re-examination of material properties data and for increased safety margins in order to make significant improvements in building energy efficiency.

In passive solar buildings, energy can be stored using either sensible heat materials or latent heat materials. Phase change materials (PCM) can contribute to temperature control in passive solar buildings when melting occurs near to comfort temperature required for building’s interior spaces. The use of finite element method (FEM) as a numerical methodology for solving the thermal problem associated with heat transfer in current building materials and PCMs make sense, as it is a well-known technique, generalized and dominated, however, still little applied to the domain of building physics. In this work, a solar model was developed and applied in order to simulate numerically the effect of solar radiation incidence on each face of the test cells (with different solar exposures) without neglecting the main objective of the recommended numerical simulation: the study of the action of PCM. During the experimental campaign, two test cells with distinct inner layers were used to evaluate the effect of solar radiation: (i) REFM test cell (without PCM) with a reference mortar; (ii) PCMM test cell (with PCM) with a PCM mortar. The temperatures monitored inside the REFM and PCMM test cells were compared with the values resulting from the numerical simulation, using FEM with 3D discretization and the explicit modeling of the solar radiation, and the obtained results revealed a significant coherence of values.

Buildings consume large amounts of energy, and their transformation from energy users to producers has attracted increasing interest in the quest to help optimize the energy share, increasing energy efficiency and environmental protection. The use of energy-efficient materials is among the proposed approaches to increase the building’s energy balance, thus increasing the performance of building facades. Semitransparent building-integrated photovoltaic (BIPV), being one of the technologies with the potential to increase a building’s energy efficiency, is considered as a feasible method for renewable power generation to help buildings meet their own load, thus serving dual purposes. Semitransparent BIPV integration into buildings not only displaces conventional building facade materials but also simultaneously generates energy while retaining traditional functional roles. The awareness in improving building energy efficiency has increased as well as the awareness in promoting the use of clean or renewable energy technologies. In this study, semitransparent BIPV technology is reviewed in terms of energy generation, challenges, and ways to address limitations which can be used as a reference for the BIPV stakeholders.

The quest for a sustainable built environment has resulted in dramatic changes in the process of residential construction. The new concepts of an integrated design team, building information modeling, commissioning of the building enclosure, and passive house standards have reached maturity. Global work on development of new construction materials has not changed, but their evaluation is not the same as in the past when each material was considered on its own merits. Today, we look at the performance of a building as a system and on the material as a contributor to this system. The series of white papers—a research overview in building physics undertaken in European and North American researchers—is to provide understanding of the process of design and construction for sustainable built environment that involves harmony between different aspects of the environment, society, and economy. Yet, the building physics is changing. It merges with building science in the quest of predicting building performance, it merges concepts of passive houses with solar engineering and integrates building shell with mechanical services, but is still missing an overall vision. Physics does not tell us how to integrate people with their environment. The authors propose a new term buildings with environmental quality management because the vision of the building design must be re-directed toward people. In doing so, the building physics will automatically include durability of the shell, energy efficiency, and carbon emission and aspects such as individual ventilation and indoor climate control. This article, which is part 1 of a series, deals with materials, and other issues will be discussed in following papers.

Salt damage can affect the service life of numerous building structures, both historical and contemporary, in a significant way. Therefore, various conservation methods have been developed for the consolidation and protection of porous building materials exposed to the salt attack. As any successful treatment of salt damage requires a multidisciplinary attitude, many different factors such as salt solution transport and crystallization, presence and origin of salts in masonry, and salt-induced deterioration are to be taken into account. The importance of pre-treatment investigations is discussed as well; in a combination with the knowledge of salt and moisture transport mechanisms they can give useful indications regarding treatment options.Another important cause of building pathologies in buildings is the rising damp and this phenomenon it is particularly more severe with the presence of salts in water. The treatment of rising damp in historic building walls is a very complex procedure. At Laboratory of Building Physics (LFC-FEUP) a wall base hygro-regulated ventilation system was developed. This system patented, HUMIVENT, has been submitted to laboratorial monitoring and to in situ validation and a numerical simplified model was developed to facilitate the practical application. Having in mind the practical application of scientific and technological knowledge from Building Physics to practice, this paper presents the design of the system (geometry, ventilation rate and hygrothermal device), the detailing and technical specification of its different components and information about the implementation in three types of buildings: a church, a museum and a residential building.

The treatment of rising damp in historical buildings walls is very complex. Moisture transfer in walls of old buildings, which are in direct contact with the ground, leads to a migration of soluble salts responsible for many building pathologies. The present work describes an extensive numerical analyse of rising damp phenomenon, using the software WUFI-2D, developed by Fraunhofer Institute for Building Physics. The results show that the numerical simulation describes very well the rising damp front for different boundary conditions and materials. The influence of the wall thickness, boundary conditions, composition of walls and material properties, such as, porosity and water absorption coefficient were analysed in detail.

Full textAbstract:
Wind discomfort and the dangers that the wind may lead can be harmful in terms of comfort conditions of both indoor and outdoor environment of the building/buildings to be constructed or just completed. The extent of discomfort to pedestrian varies from inducing slightly unpleasant feeling to producing a falling down hazard. Typically, the cause of frequent occurrences of strong wind at pedestrian area is primary related to the configuration of building structures and/or topography in the vicinity of the pedestrian area. Depending on the characteristics of the wind including magnitude, uniformity, ambient temperature, and so on, the level of disturbance to users of pedestrian areas can be different. In this context, the regions where Necmettin Erbakan University temporary education buildings are located have a fairly intensive topography in terms of wind. Therefore, detailed analysis of the inside regions and the surrounding areas of education buildings in particular are performed in terms of microclimatic comfort and indoor energy recovery. Especially, the topography where university campus temporary educational buildings are located has very high wind climate conditions compared to the city of Konya climate conditions. In this study, pedestrian-level wind conditions around N.E.U. campus buildings and in urban areas and the topography of campus settlements were analyzed through on-site measurement with Delta OHM microclimatic instruments. The purpose of this study is to investigate the pedestrian-level comfort conditions around the project buildings suggested by concept architects together with microclimatic measurements of comfort conditions, in the light of current topographic and climatic conditions presented by the head architect. However, presentation of these topographic and microclimatic measurements around currently completed temporary classrooms of the university campus have not yet been completed. The topography of the university campus, which is at an altitude higher than that of Konya centrum, is exposed to an extremely high wind velocity. The pedestrian-level comfort conditions are measured using Delta OHM instrument. The study also aims to compare pedestrian-level comfort conditions at locations of various buildings. In addition, outdoor comfort survey was also conducted in the campus area. However, measurement results of the microclimatic measurement device, DeltaOHM, are evaluated in this study. It can be observed from the results that pedestrian-level comfort of current campus settlements around the buildings reach very discomforting levels. Since the university’s topography varies between very high and very low temperature levels and wind velocity values, climatic comfort problems are observed in the area. Some reasons for the discomfort problems observed in current settlement are; incorrect use of climatic parameters, incorrect directions of buildings, thermal effects due incorrect selection of materials used in constructions of buildings. In order to achieve thermal comfort, more studies are required on pedestrian-level comfort, use of passive design techniques such as correct direction of buildings and correct selection of materials utilized in the buildings based on their thermal effects. This would help university campus buildings consume less energy and maximize people’s satisfaction.

Full textAbstract:
Reliable and high-fidelity virtual ruin scenarios for collapsed buildings are essential for post-earthquake emergency search and rescue training. However, the existing research on the distribution of ruins caused by building collapse is insufficient for supporting post-earthquake rescue training. Therefore, this paper proposes a hybrid framework for simulating building collapse and ruin scenarios, using a finite element (FE) model and a physics engine. Based on this framework, the following methods are proposed: (1) geometric model conversion from the FE model to the physics engine; (2) determination of the initial moment of collapse; and (3) data mapping of the FE simulation results. In addition, a corresponding program, Finite Element Method to Rigid Body Dynamics (FEM2RBD), is developed for the hybrid framework. The proposed framework simulates the entire process of building collapse and the distribution of ruins. The accuracy of the framework is validated using a shaking table test of a three-story reinforced concrete frame. The collapse process and ruin scenario of a real-world library building is simulated as a case study. The results show that the proposed framework combines the advantages of the FE model during the small-deformation stage with the advantages of physics engines during the large-deformation stage. The proposed framework can be valuable in simulating building collapse and ruin scenarios for post-earthquake rescue training.

Radiative heat transfer is the most effective mechanism of energy transport inside buildings. One of the methods capable of computing the radiative heat transport is based on the system of algebraic equations. The algebraic method has been initially developed by mechanical engineers for wide range of thermal engineering problems. The first part of the present serial paper describes the basic features of the algebraic model and illustrates its applicability in the field of building physics. The computations of radiative heat transfer both in building enclosures and also in open building envelopes are discussed and their differences explained. The present paper serves as a preparation stage for the development of a more general model evaluating heat losses of buildings. The general model comprises both the radiative and convective heat transfers and is presented in the second part of this serial contribution.
