Full textAbstract:
Using building information modeling (BIM) and Ecotect, this paper estimated carbon emissions during an office building’s life cycle. This building’s life cycle CO2emissions were divided into three parts: the construction, operation, and demolition stages. Among these, the statistics on the schedule of quantities were generated using BIM, and the energy consumption during the building’s operational stage was obtained using ECOTECT simulation. Sensitivity analysis was performed by changing several alternative parameters, to identify which parameter has more impacts on building performance. The paper demonstrated that (1) BIM and Ecotect are very helpful in estimating carbon emissions from a building’s life cycle, (2) the primary and effective measures to reduce the building’s CO2emissions in hot and humid climate should be arranged as follows: (a) within the limits of comfort, reducing the fresh air volume; (b) extending the indoor temperature range; (c) improving the thermal insulation performance of exterior windows, walls, and roofs; (d) exploiting natural ventilation during transition seasons, and (3) currently there are some limitations in performing LCA based on BIM and Ecotect.

Abstract: An audio-visual room is a room specifically designed to enable users to have enjoyable listening and watching video activities. This study was conducted to find out correlation between acoustics quality and acoustics materials in audio-visual room of Musi Charitas University. The methods of this research were descriptive method using ecotect simulation. The simulation revealed that: (1) The replacement of ceiling materials improve the quality of sound quality since it’s reverberation time approximately 47.9 ms.; (2) The replacement of ceiling materials caused the reverberation time (RT) becomes eligible, with the tolerance of about 10% of the standard 50 ms. Thus, it was not necessary to change the wall layers on the right and the left sides because the RT of the audio-visual room matched the speech RT (0.5-1.0s). Before the ceiling materials were replaced, the RT in the 250 Hz frequency was 0.41s. That is why it is important to decide to use the right absorption coefficient so that the reverberation time in the audio-visual room would be equal or within the range of 0.5-1.0s.Keywords: room acoustics quality, acoustics materials, Ecotect analysisAbstrak: Ruang audio-visual merupakan ruang yang dirancang dengan kualitas akustik yang baik yaitu mampu memaksimalkan efek perangkat audio-video sehingga mendukung kenikmatan pemakai dalam mendengarkan dan menonton pertunjukan audio-visual. Penelitian ini bertujuan mengetahui keterkaitan kualitas akustik dengan material akustik pada ruang audio visual di Universitas Musi Charitas. Penelitian dilakukan dengan metode deskriptif dan simulasi ecotect. Hasil simulasi menunjukkan bahwa (1) Penggantian material plafond meningkatkan kualitas akustik karena garis suara mencapai pendengar di tengah ruangan akibat mengalami pantulan plafond dan dasar sekitar 47,9 ms; (2) Setelah dilakukan penggantian bahan pada plafond, waktu dengung menjadi memenuhi syarat karena adanya toleransi sekitar 10% dari standar 50 ms. Akibatnya, perubahan lapisan dinding samping (kiri dan kanan) tidak diperlukan, walaupun garis suara mengalami sedikit pemantulan pada dinding samping, (3) Waktu dengung ruang Audio-Visual mencapai waktu dengung sesuai dengan kriteria waktu dengung speech (sekitar 0,5 – 1,0 sekon).

This research compared the traditional urban form of old Sana'a with the modern by applying three main basic principles of sustainability; 1. Form and density, 2. Walkability and connectivity and 3. Building energy. The method of inquiry was based on qualitative and quantitative methods and analysis using GIS, ECOTECT and Space Syntax modelling. The findings show that traditional form with its higher building density and compactness is a good model with regards to sustainable principles. Similarly, as to walkability index, traditional layout has higher rates of intersections and connected nodes and least angular changes with higher rates of integrations and choices in terms of Space Syntax properties than new layouts. Finally, the result of applying ECOTECT for urban solar analysis to confirm that the traditional pattern achieved sufficient values of solar access, exposure and shadows over different periods of the year. The overall results indicate that the traditional urban layout is more sustainable in terms of form and density, walkability and connectivity and urban solar energy than the new layouts.

Contemporary architectonic design mostly relies on the software tools which enable the engineers to analyze multiple factors affecting a space, and to timely detect and correct certain errors in designing, resulting from attempting to satisfy certain aspects of a space at the expense of others. Those tools which apart from architecture itself also consider other fields of science, depending on the function of these areas are important; thus in the lecture halls designing process, adequate software for analysis is used. In addition to a number of acoustic parameters characterizing the acoustic response of a room, in terms of design, one of the most important factors affecting the acoustics of the indoor areas is reverberation time, which is characterized by the architectonic parameters: room volume (dimensions), shape (form) and materialization (finish material). In this paper, for the purposes of acoustic analysis of the A amphitheater, the parametric values obtained in two ways, by experimental measuring and by software - Autodesk Ecotect and Autodesk Revit Architecture are compared. The software is increasingly used in contemporary architectonic software because of the option to analyze acoustics of indoor space, so there is a need to analyzed the values provided by the software and compare them with actually measured reverberation time.

Daylight is the occupied-range of light that is appropriate to the human visual response. Thus, it can contribute to human health, performance and productivity. Energy consumption can be reduced by improving in energy efficiency. The study emphaseson the design of lighting system that will be energy efficient. The basic purpose of this paper describes how to reduce the mounted lighting load and improve the illumination level as per international standards. A good lighting scheme should be based on more energy efficient & longer life and maintenance free equipment. In this research paper,a hypothetical study space is selected for the daylight analysis on the Ecotect and the Radiance software on summer solstice and winter solstice days under over cast sky condition. Ecotect software is used to determine lighting demand inside the selected study space and the obtained data is exported on Radiance for detailed and more accurate daylight analysis. It is pragmatic that illuminance level is varied with respect to date and time that are clearly expressed by the daily sun path and shadow range. It is also perceived that the installed artificial luminaries does not provide the required illuminance on the working plane and consume more energy. The major aim of this research is to reduce the lighting load by introducing energy efficient artificial luminaries into the room that provide the required illuminance level on the working plane. Lumen method is used to explain the energy saving which is carried out according to existing energy consumption compared with the proposed one. At the end cost comparison of energy consumption and payback period is also calculated. This study shows that overall cost saving in energy consumption is approximately 34.37% and the calculated payback period for the newly installed lights is comprising of approximately 11 months.

Nature has its own astonishing capability to naturally cleanse the environment. Living green drapes on buildings look elegant and can provide sustainable solutions in congested cities. The Vellore Institute of Technology in India promotes green values within the country. Although the campus is lush and verdant, its ever growing student population precipitated an increase in public thoroughfare causing air pollution. To partially alleviate this problem, walls of a subway connecting the main academic campus and the hostel premises are draped with Vernonia elaegnifolia creeper; this is aesthetically elegant and was found to be efficient in capturing much of the vehicular pollution within the subway. An experimental investigation clubbed with an Ecotect analysis helped ascertain the optimal duration of the temperature drop across the subway. The analysis also predicts an annual savings of 36000 USD per hostel block. A detailed Scanning Electron Microscopic analyses coupled with Spectrophotometry established the deposition pattern of sulphates and nitrates. It is expected that the results of this analysis will promote the use of green facades in this sun drenched country.

Purpose The purpose of this paper is to explore and rank the benefits and barriers (technological and non-technological) of using Building Information Modelling (BIM) in sustainable building design. It also employs the use of a design tool analysis of a case study using BIM compatible tools (Ecotect and Green Building Studio) to determine the environmental performance of a proposed multi-use building at Derby North. Design/methodology/approach The paper explores the benefits and barriers of using BIM through a literature review. Regression and factor analysis were used to rank these benefits and barriers. A questionnaire was distributed to a sample of 120 practitioners with 69 completing the survey. Finally, the paper employs the use of a design tool analysis of a case study using BIM-compatible tools (Ecotect and Green Building Studio) to determine the environmental performance of a proposed multi-use building at Derby North riverside. Findings The key findings of the statistical analysis indicated that professionals ranked the integrated project delivery as the most established benefit, while the lack of interoperability was ranked the greatest technological challenge. Only three of the attributes of non-technological challenges made statistically unique contributions, namely, training costs and software costs, client demand and potential legal issues. It was also discovered that BIM delivers information needed for environmental performance. In a forward-looking approach, the paper attempts to provide some recommendations that would encourage the continuous application of BIM in sustainable building design. Research limitations/implications This paper does not cover all features of BIM functionality, as the scope of BIM is very enormous and the resources of this research were limited. Practical implications The implication of the study is that it will assist in exploring and ranking the benefits and barriers (technological and non-technological) of using BIM while proffering recommendations for future use. This research will be of interest to industry practitioners and academic researchers with an interest in building information modelling. Originality/value This paper contributes with new outlooks aimed at syndicating sustainability with environmental performance and adds to the limited empirical studies on the benefits and barriers of the application of BIM.

Building-integrated photovoltaics (BIPV) is a relatively recent new application of photovoltaic (PV) energy technologies whose energy output is affected by many design-related factors including PV module technologies, installation orientation, tilt and shadow range of solar panels. The shading analysis of a residential house’s PV roof in Beijing was conducted by using building analysis program Autodesk Ecotect 2010. Analysis result shows that there is no shadow on the PV roof from 9a.m to 4p.m in winter solstice when the solar altitude angle reaches minimum, which ensures almost no shading losses for the PV modules over the year. The differences in monthly energy output were compared in the case of different installation tilt of solar panels and PV module technologies. Finally, the contribution to the building energy of the PV roof was discussed. The results show that appropriate design and selection of PV modules can compensate for the energy requirements for building heating and cooling to some extent.

Compared to open spaces the complex surface structure of urban areas creates an environment with special microclimatic characteristics, which have a dominant effect on the energy balance of the human body. In this study, outdoor thermal comfort conditions are examined through numerical model with different transparency ratios in canopy. The intensity of radiation fluxes is dependent on several factors, such as orientation, size and transparency of canopy. Special emphasis is given to the human-biometeorological assessment of the microclimate of building element (canopy) through the application of the thermal index PET (Physiological Equivalent Temperature). The analysis is carried out by the utilization of Ecotect and RayMan software.

The study presents the results of typological analysis and simulation modeling analysis of traditional courtyard residential houses in the cold semi-arid climate of Iran. The purpose of the research has been to analyze and evaluate traditional passive environmental strategies and their elements to provide implications for the design of sustainable residential buildings in contemporary time. Five existing traditional courtyard houses in the city of Tabriz, Iran, are used as case-studies to analyze the typology and the solar zoning conditions and to develop simulation models. The Ecotect simulation program is used to calculate the solar gains of the buildings and to analyze the effectiveness of the natural passive systems along with native design strategies in terms of potential solar gains of main and secondary living spaces. However, in the vernacular, not only the awareness of the climatic and topological considerations is important, but also the values, rituals, and beliefs that shape the design of the dwellings need to be considered. The research is based on the hypothesis that vernacular buildings (courtyard houses) of Iran have been environmentally sustainable structures. However, an important challenge of the study has been to avoid the technological bias and to consider the cultural and social aspects and embodiment of the studied houses, as well. The study also addresses the potential shortcomings that limit the reliability of Iranian vernacular architecture at present in order to arrive at a more holistic understanding of the sustainability of the vernacular architecture in the country.

A study on thermal retrofit of Portuguese elementary school buildings is presented. The type of school under analysis is one adopted by a large construction campaign that began in the 1940's. This building stock has a very poor thermal performance and their retrofit was evaluated starting with a case study of a school in the central region of Portugal, where some experimental measures were performed and a calculation method was applied for the heating energy consumption estimation. A solution for the thermal retrofit of the school building external envelope was optimized and the effect on heating energy consumption was evaluated, using ECOTECT, resulting in a reduction of 52% of heating energy needs. The national impact of the thermal retrofit of the whole building stock was characterised in terms of energy savings. Finally, the pre‐heating of the ventilation air was also tested as a complementary measure and its effect evaluated. The solution tested may provide up to 1000 kWh/year of extra heat gains by pre‐heating the ventilation air. It must be underlined though that the performance of these systems is dependent on the thermal properties of their components so higher reductions can be achieved with the improvement of these properties.

The painting is one of the most decorative elements of ancient Chinese architecture and it is sensitive to the natural environment. The outdoor painting is very easily to be affected by the natural environment and its color is easily to decay. In order to study the relationship between the painting decay and the physical environment, the two paintings on both east and west inner eaves of Jilan Pavilion beside the Kunming Lake in Summer Palace are taken as the research objects, because these two paintings are painted at the same period but their decay degrees are greatly different. Since 2013, the research group regularly monitors the color decay of these two paintings. Meanwhile, the physical environment around these two paintings has been monitored. Based on the analysis of the monitor data, it can be seen that the illumination is the major factor that causes the decay of the painting. Meanwhile, by using the ECOTECT software to stimulate the light environment around the Jilan Pavilion, it can be seen that it is the mirror reflection of the lake that causes the result that the illumination of the west eave (face east) is stronger than that of the east eave (face west).

ABSTRACT The window system is generally regarded as the most vulnerable building system for the indoor energy performance of green buildings. Window systems are given significant attention by architects and engineers, especially in areas with long summer and high solar radiation such as the subtropics. This study aims to develop a standard window-to-floor ratio (WFR) system for green residential buildings in the subtropics. Using Autodesk Revit as the interface, a real high-rise residential building was digitalized and imported into Ecotect for energy consumption analysis. Comparative analyses were conducted to determine the optimal WFR for building energy efficiency. Results demonstrated 0.23 as the optimal WFR in Xiamen, one of the typical subtropical cities in Asia. Furthermore, accompanied by a four-sidefins sunshade device and a double glass window (DGW) with clear “glass+air gap+reflective” glass, the building energy consumption was further reduced by 34.47% compared to the initial model, which successfully met the optimization target of 30%, set according to the green building standard. The results of this study are helpful to architects and building engineers when designing or retrofitting green buildings as we provide specific support for design features for energy performance.

Full textAbstract:
Daylighting integrated with artificial lighting control is recognized as an important and useful strategy in energy-efficient building designs. The prediction of the internal daylight levels is a key stage in daylighting designs. For this research, the ‘type design’ residential quarters building as a case has been selected from Nagpur region in central India having a hot and dry climate. These ‘type design’ have the major issues related to the performance of daylight and thermal comfort due to lack of some rules related to sizes of fenestrations in the development control regulation. The aim of this research is to evaluate the most critical liveable area of a dwelling unit of ‘type design’ for daylight and thermal comfort. This research includes evaluation of the selected parameters by comparative analysis of useful daylight illuminance (UDI), daylight autonomy (DA), thermal comfort hours and carpet area to window ratio (CAWR) with the help of dynamic simulation by using ‘Daysim’, ‘radiance analysis tool’ and ‘temperature distribution tool’ of Ecotect 2011 software. The findings of this research arrive to derive the CAWR with respect to orientation (four cardinal directions) of the building without compromising the thermal comfort with respect to the temperature of a dwelling unit of ‘type design’.

Full textAbstract:
During the last years, European government remuneration polices promoted the realisation of photovoltaic systems integrated with the structures instead of on ground photovoltaic (PV) plants. In this context, in rural areas, greenhouses covered with PV modules have been developed. In order to interdict the building of greenhouses with an amount of opaque panels on covering not coherent with the plant production, local laws assigned a threshold value, usually between 25% and 50%, of the projection on the soil of the roof. These ranges seem not to be based on scientific evaluation about the agricultural performances required to the building but only on empirical assessments. Purpose of this paper is to contribute to better understand the effect of different configurations of PV panels on the covering of a monospan duo-pitched roof greenhouse in terms of shading effect and energy efficiency during different periods of the year. At this aim, daylighting and insolation analysis were performed by means of the software Autodesk<sup>®</sup> Ecotect<sup>®</sup> Analysis (Autodesk, Inc., San Rafael, CA, USA) on greenhouse model with different covering ratio of polycrystalline photovoltaic panels on the roof.

Full textAbstract:
In recent years the use of photovoltaic panels as cover materials for greenhouses developed a great interest due to the state’s incentives obtainable by such applications. Shading caused by these elements inside the structure appears to be often too much for the normal development of agricultural activity. In this study it was analyzed the behaviour of shading caused by the photovoltaic panels inside a prototype of dynamic photovoltaic greenhouse whose particularity lies in the possibility of rotation of the panels along the longitudinal axis. The panels’ rotation allows varying shading degree in function of some parameters such as latitude and the different solar angles. In order to avoid any reflection losses due to imperfect inclination of the photovoltaic panels, 24 highly reflective aluminium mirrors were prepared with the objective of recovering the portion of solar radiation otherwise lost by reflection. For the study it was used the simulation software Autodesk® Ecotect® Analysis which allows to analyse the path of the shadows during the day and throughout the year for any latitude considered. For this study it was analyzed shading with the panels in a horizontal position. It was also analyzed the evolution of the percentage of shading simulating different latitudes. The results obtained show a great variation of the shading degree inside the structure during a single day and during the year. We can conclude that integrating this analysis with the energy balance it is possible to study the behaviour of photovoltaic greenhouses in order to integrate the energy production from renewable energy sources and agricultural production.

By regulations on energy efficiency from 2011, the simplified methodology for calculating solar gains has been defined by the adopted values of solar radiation for whole of Serbia. This paper presents two different methods of solar gains calculation, with the support of the software package KnaufTerm 2, which relies on existing regulations in Serbia, and Ecotect software package, intended for 4-D simulations. The problem has been analyzed in the case of a residential building in Belgrade, by calculating solar gains obtained through one window, for 36 different orientations. Different orientations of the window have shown significant variations in the obtained results, which have been ignored by the rulebook, be-cause it defines only 4 orientations. By this, it was established that four more orientations have to be defined by regulations, with separate values of solar radiation for each position. As the differences in solar gains are most visible in the east, and deviate up to 61%, in the paper then was analyzed calculation method of shading for eastern orientation, which is defined by the rulebook on energy efficiency through a variety of shading factors. The analysis has shown that the methodology defined in the regulations has given drastically lower levels of solar gains at the shaded positions, where the most visible differences were observed in the presence of three shading elements. Also, it is necessary to reconsider the values of the defined shading factors, which are, as showed by 4-D simulations, oversized.

The global energy context of the year 2018 makes us pessimistic about the future. The geopolitical, environmental and socio-economic aspects are linked to the political tensions of countries that hold and manipulate the global energy market. These countries are haunted by the population growth, the depletion of fossil resources and the global economic crisis. Each country is trying to find reasonable solutions to deal with this crisis. Unfortunately, these solutions always have direct negative repercussions on the population and on the environment. In this paper we present a case study developed in Algeria and inspired by the current and critical socio-economic situation of the country, in particular, the application of energy-saving techniques to an existing building. The investigation was conducted by using both simulation software and real interventions. We analyse some of the major components, such as building’s orientation and exposure to daylight which have significant impact on energy consumption. We present the concept of Building Performance Simulation Analysis, using Autodesk ECOTECT Analysis and COMSOL Multiphysics software, and give full consideration to various ecological energy-saving methods. Using our models, we present a possible solution for retrofitting a building to minimize its energy consumption. The results are useful for both building energy conversation and creating a comfortable living environment in future.

In conservation strategy, the building should concern on integration preserving the heritage value and planning of all care utilities. Therefore, this research reviews for sustainable and livable heritage hospital and were conducted through research phases as follows: Existing review, sustainable and green planning for critical building services, and environmental analysis using Ecotect Analysis and Matlab software environmental simulation. Dr. Soetomo Hospital is selected as the urban heritage object case. The results highlighted that the urban hospital should have design routes for building services integrated with mass management and architectural concepts as well as landscape design, and standardization of planning and system component life, designing the inner and/or outer rings will be potential planning. By conducting on to the existing high-density buildings evaluation, the building services master plan remains to be used is the zoning system pattern related with heritage conservation strategy. To anticipate the future projection, it is necessary to adjust the environmental performance because the utility system should accommodate the respective heritage for the requirement of facilities, capacity, and technology of green hospital concept.

Buildings not only can be resilient from environmental changing by passive design, but also have ability to adapt the environment by active system. By using deployable structure, this system can be provided by changing multiple form based on its purpose to cover the building. To provide these conditions, deployable structure need to be explored and analyzed to develop compatible structure in the building. Case of study in this research is Pajajaran sports building in Bandung. The research method is exploration of form and movement based on limited variables, there are activities and weather changing/climate condition. These variables formulated into two conditions, open and closed building. Open building state in sports building have requirement that either natural or artificial lighting should not cause glare in field area. So, natural lighting was simulated by using Ecotect Analysis to find solar path movement and shadow angle. The result of the solar path simulation shows that daily solar movement must be responded directly because high rotation rate and regular changes, while the monthly sun path does not require significant movement due to low rotation rate and insignificant changes. This study will show design process of deployable structure into sports building.

Abstract The application of advanced materials in energy conservation is mostly among the urgent issues worldwide. In this context, nanosilica aerogel has received growing attention in the last decade due to its remarkably lower thermal conductivity. Aerogel panels laminated to drywall boards initiated to be used in substantially the energy sufficient buildings. Nevertheless, the greatest and most promising application of silica aerogel appears to be in substantially insulating glazing systems. The present research has concentrated on evaluating the energy performance of the nano aerogel glazing if implemented to the El-Dakahliya governmental headquarters building located in Mansoura city in Egypt, compared with single-glazed windows (base case) and double-glazed windows. The modeling was carried out in Autodesk Revit, and the process of energy performance simulation was carried out by Autodesk Ecotect Analysis by adopting the weather data of Mansoura. The results show that the nano aerogel glazing system succeeds in conserving approximately 19% in the annual energy consumption for a set-point temperature band of 19–27°C. The paper attempts to present significant research especially in studied country. Selected category of buildings may add more originality in term of implementation scope.

Hasil penelitian membuktikan bahwa dinding double brick cavity plaster paling hemat energi karena paling mampu mengurangi perolehan solar heat gain. Kaca jendela double glazed Low-E aluminium frame juga lebih mampu mengurangi solar heat gain daripada kaca jendela double glazed aluminium frame. Penggantian material dinding lebih efektif dalam mengurangi solar heat gain daripada kaca jendela karena luasan dinding jauh lebih besar daripada luasan kaca jendela pada kulit bangunan.
