Traditional energy analysis in Building Information Modeling (BIM) only accounts for the energy requirements of building operations during a portion of the occupancy phase of the building’s life cycle and as such is unable to quantify the true impact of buildings on the environment. Specifically, the typical energy analysis in BIM does not account for the energy associated with resource formation, recycling, and demolition. Therefore, a comprehensive method is required to analyze the true environmental impact of buildings. Emergy analysis can offer a holistic approach to account for the environmental cost of activities involved in building construction and operation in all its life cycle phases from resource formation to demolition. As such, the integration of emergy analysis with BIM can result in the development of a holistic sustainability performance tool. Therefore, this study aimed at developing a comprehensive framework for the integration of emergy analysis with existing Building Information Modeling tools. The proposed framework was validated using a case study involving a test building element of 8’ × 8’ composite wall. The case study demonstrated the successful integration of emergy analysis with Revit®2021 using the inbuilt features of Revit and external tools such as MS Excel. The framework developed in this study will help in accurately determining the environmental cost of the buildings, which will help in selecting environment-friendly building materials and systems. In addition, the integration of emergy into BIM will allow a comparison of various built environment alternatives enabling designers to make sustainable decisions during the design phase.

A mensuração do desempenho ambiental pela metodologia de Avaliação do Ciclo de Vida (ACV) possibilita a compreensão dos impactos ambientais nas etapas do processo de produção de uma edificação. Para facilitar esse processo pode ser utilizado o Building Information Modeling (BIM). Neste contexto, o presente trabalho consistiu no estudo e avaliação da aplicação do BIM na ACV de edificações a partir de um estudo de caso utilizando softwares que trabalham na plataforma BIM, o Autodesk Revit e o DesignBuilder. Foi possível estimar as emissões de CO2 na fase de pré-uso de uma edificação escolar. No entanto, notou-se problemas na questão da interoperabilidade quando o modelo é exportado do primeiro para o segundo software. A quantificação das emissões foi realizada ainda manualmente, para comparação com os resultados fornecidos pelo software. Os resultados mostraram que a quantificação de CO2 é mais precisa para sistemas construtivos homogêneos, como paredes de concreto. A principal contribuição do presente estudo foi a verificação da viabilidade do software DesignBuilder para a quantificação das emissões de CO2 no ciclo de vida das edificações, como uma ferramenta de projeto para edificações de baixo carbono. Abstract The measurement of environmental performance using Life Cycle Assessment (LCA) methodology enables comprehensive understanding of environmental impacts in all stages of the production process of a building. In order to facilitate this process can be used the Building Information Modeling (BIM). In this context, the present paper aims to study and evaluate the implementation of BIM in LCA of buildings from a case study using software that works on the BIM platform, Autodesk Revit and DesignBuilder. It was possible to estimate the CO2 emissions in the pre-use stage of a school building. However, problems have been noted in the interoperability issue when the model is exported from the first to the second software. The CO2 emission quantification was still performed manually, for comparison with the results provided by the software. The results showed that the quantification of CO2 is more accurate for homogeneous constructive systems, such as concrete walls The main contribution of the present study was the verification of the viability of the DesignBuilder software for the quantification of CO2 emissions in the life cycle of buildings, as a design tool for low carbon buildings.

In the conditions of rapid scientific and technological progress, the technologies development pace of designing buildings and structures began to outstrip the practical application of them in the domestic market in comparison with the countries of the western world. Ukrainian building design tools have ceased to be internationally competitive. In these circumstances, it is especially important to introduce new and improve existing methods and tools for modeling buildings and structures. An important task for a modern designer is the ability to use a computer model at various stages of the building's life cycle, namely: design, construction, operation. To solve this problem, one can apply a new design method - Building Information Modeling (BIM). The purpose of this research is to explore the possibilities of using information modeling technologies for buildings as a means of their life cycle managing. The scientific and practical importance of the work stands in the possibility of introducing of information modeling technologies of buildings not only as a new design method, but also as a means of managing of the life cycle of the building at all its stages. The results of the research are based on the analysis of literary sources and practical experience of the authors. The article revealed the possibility usage of building information modeling as means of managing of the life cycle of building and structures. There is considered options and the main problems of information modeling application on different stages of buildings life cycle. In this paper, the main functions of building information modeling, which are necessary for managing of the life cycle of buildings and structures, have been analyzed and formulated. The practical importance of the results of this paper is in the presentation of the proposed functions and development prospects of building information modeling tools.

Assessment Results

Eco-friendly building designs that use building information modeling (BIM) have become popular, and a variety of eco-friendly building assessment technologies that take advantage of BIM are being developed. However, existing building environmental performance assessment technologies that use BIM are linked to external assessment tools, and there exist compatibility issues among programs; it requires a considerable amount of time to address these problems, owing to the lack of experts who can operate the programs. This study aims to develop eco-friendly templates for assessing the embodied environmental impact of buildings using BIM authoring tools as part of the development of BIM-based building life cycle assessment (LCA) technologies. Therefore, an embodied environmental impact unit database was developed, for major building materials during production and operating stages, to perform embodied environmental impact assessments. Moreover, a major structural element library that uses the database was developed and a function was created to produce building environmental performance assessment results tables, making it possible to review the eco-friendliness of buildings. A case study analysis was performed to review the feasibility of the environmental performance assessment technologies. The results showed a less than 5% effective error rate in the assessment results that were obtained using the technology developed in this study compared with the assessment results based on the actual calculation and operating stage energy consumption figures, which proves the reliability of the proposed approach.

The objective of this paper is to apply the life cycle assessment methodology to assess the environmental impacts of light steel framed buildings fabricated from cold formed steel (CFS) sections. The assessment covers all phases over the life span of the building from material production, construction, use, and the end of building life, in addition to loads and benefits from reuse/recycling after building disposal. The life cycle inventory and environmental impact indicators are estimated using the Athena Impact Estimator for Buildings. The input data related to the building materials used are extracted from a building information model of the building while the operating energy in the use phase is calculated using an energy simulation software. The Athena Impact Estimator calculates the following mid-point environmental measures: global warming potential (GWP), acidification potential, human health potential, ozone depletion potential, smog potential, eutrophication potential, primary and non-renewable energy (PE) consumption, and fossil fuel consumption. The LCA assessment was applied to a case study of a university building. Results of the case study related to GWP and PE were as follows. The building foundations were responsible for 29% of the embodied GWP and 20% of the embodied PE, while the CFS skeleton was responsible for 30% of the embodied GWP and 49% of the embodied PE. The production stage was responsible for 90% of the embodied GWP and embodied PE. When benefits associated with recycling/reuse were included in the analysis according to Module D of EN 15978, the embodied GWP was reduced by 15.4% while the embodied PE was reduced by 6.22%. Compared with conventional construction systems, the CFS framing systems had much lower embodied GWP and PE.
