“…Notable in this regard is that TBS only has a material mass share of usually around 1-4% of the total building. For example, in the case of GHG emissions CO2 emissions are significantly higher than 20% or 30% (Lambertz et al, 2019;Schneider-Marin et al, 2019). Within TBS, HVAC becomes a key role as it consists of materials like metals and plastics, which cause high material-related environmental impacts due to energy-intensive manufacturing processes and short service life.…”

In order to reach the goal of a net-zero carbon society, the construction industry plays a significant role. Optimising the performance of new buildings in early design phases requires the analysis and evaluation of environmental impacts by life cycle assessment (LCA). The semantic building model can be employed to automatically derive necessary information for LCA to reduce the manual calculation effort. Existing approaches using Building Information Modelling (BIM) for LCA mainly take the operational and the embodied impacts of the building construction materials into account. Still, they do not consider technical building services (TBS), especially in early design phases. However, the embodied carbon of TBS has a significant impact (up to 30% for office buildings) on the whole building LCA and is generally underestimated. Usually, it is considered as a factor of the total LCA but rarely calculated in detail.To identify the research gap, this paper first presents a literature review on existing approaches of the research field of BIM-based LCA of building services. There are just a few approaches in this field, and none of the BIMbased ones are applied in early design phases. The literature review classifies publications in different aspects, such as design phase, TBS Scope, LCA scope, and BIM integration. In a second step, a new methodology focusing on early design phases is presented. As in early design phases, we assume not to have a TBS model yet, an energy demand analysis and pre-dimensioning of TBS components are included in the methodology. Afterwards, LCA is calculated for the main TBS components based on the quantity take-off of the pre-dimensioned components.

“…In the field of LCA of buildings, there were several options to link the building information model (BIM) with LCA software. Tally, for instance, is a plugin for the planning software Revit that allows information about building materials to be entered into the software and quantifies environmental impacts based on that information [68,69]. In addition, several interface tools have been developed to link BIM with LCA software and automatically extract relevant LCI data from the BIM [70][71][72][73][74].…”

How to Simplify Life Cycle Assessment for Industrial Applications—A Comprehensive Review

Life cycle assessment (LCA) has established itself as the dominant method for identifying the environmental impact of products or services. However, conducting an LCA is labor and time intensive (especially regarding data collection). This paper, therefore, aims to identify methods and tools that enhance the practicability of LCA, especially with regard to product complexity and variance. To this end, an initial literature review on the LCA of complex products was conducted to identify commonly cited barriers and potential solutions. The obtained information was used to derive search strategies for a subsequent comprehensive and systematic literature review of approaches that address the identified barriers and facilitate the LCA process. We identified five approaches to address the barriers of time and effort, complexity, and data intensity. These are the parametric approach, modular approach, automation, aggregation/grouping, and screening. For each, the concept as well as the associated advantages and disadvantages are described. Especially, the automated calculation of results as well as the automated generation of life cycle inventory (LCI) data exhibit great potential for simplification. We provide an overview of common LCA software and databases and evaluate the respective interfaces. As it was not considered in detail, further research should address options for automated data collection in production by utilizing sensors and intelligent interconnection of production infrastructure as well as the interpretation of the acquired data using artificial intelligence.

PurposeThe construction sector is increasingly engaged to explore the potential application of building information modelling (BIM) for the sustainability of the buildings. BIM can be applied conjugated to certification methods to evaluate the sustainability of the buildings, and it is known as building sustainability assessment (BSA). This article aims to explore applications of BIM in the sustainability analysis of buildings, including five types of BSA.Design/methodology/approachA literature review from 2009 to 2020 considering a combination of search terms related to BIM and BSA complemented the analysis. The bibliometric analysis indicates an increase in the number of publications on this topic of study in the last five years. A peak occurred in 2015 and 2020, with 51 and 66 publications, respectively.FindingsThe results showed that BIM contributes to achieving part of the sustainability requirements from BSA, especially quantitative requirements that are related to material and resources. However, a complete analysis between BIM and BSA is still a challenge since part of BSA's have a lack information in their requirements and BIM softwares present interoperability problems that difficult an integrated analysis to extract information directly from the software to attend BSA's requirements.Originality/valueThe results contribute to analysing the evolution of studies about BIM and to understand the limitation in the applicability with sustainability rating systems. Future directions of research indicate the necessity to improve the use of BIM in the sustainability analysis of the buildings, but with a good perspective regarding the application of BIM in material and resources requirements, and waste management in construction sites.
