Although the use of different sources and formats of environmental information may hinder the understanding of varying LCA results for different LODs, a solution is proposed for the parametrisation of environmental information in BIM objects, according to their LOD.įor this paper, a critical review was developed, including the applicable normative framework and the research works previously published. This work will, thus, explore the BIM-LCA integration from a different perspective, i.e., by discussing the type of LCA information that is relevant to be integrated into BIM objects, depending on their LOD. In parallel, the environmental LCA methodology, concepts and terminology are still not commonly used by these professionals and need to be further explained and integrated into their practice. Currently, few publications explicitly relate the integration of LCA and BIM methods to the specificity and requirements of different stages in the design and construction process (different Levels Of Development - LOD). A model LOD 300 is referred to in the literature as a requirement for the use of the bill of materials to perform the LCA. To the extent of the authors’ knowledge, only one study has treated the option of having LCA-based information evolving since the early stages of design, for instance, LOD100, until the later and more detailed ones, as LOD 400 or even 500. Even though this approach has fewer limitations than the first, it is still important to discuss the practical use of these approaches by Architecture, Engineering and Construction (AEC) professionals. Nowadays, BIM models are used for the automatic materials’ quantity take-off and connected with external LCA databases ( e.g.

More recent studies have a different approach, though.

However, the lack of interoperability and considerable manual work were some of the limitations of this approach. 2013, Jalaei and Jrade 2014, Sharif and Hammad 2019 or Wang et al. The first approach followed by the researchers focused on the integration of BIM with numerous programs to conduct an LCA study of a building, e.g. Great potential has been identified in the use of combined BIM and LCA methodologies, and some research works have been published regarding this synergy. This feature allows for more accessible information management and potentiates optimised approaches to facilities management. An essential characteristic of BIM is its collaborative and life cycle approach, considering the several phases of the buildings (or infrastructures) LC. Although there are different definitions, BIM is commonly defined as “a digital representation of physical and functional characteristics of a facility” as well as the base for a shared knowledge (and decision support) resource for information during its life cycle (from earliest conception to the end of life stages).

īuilding Information Modelling (BIM) may become a valuable tool to improve the energy performance and resource efficiency of buildings. It quantifies all relevant emissions, consumed resources and the potential impacts caused by a product or service.

LCA is a structured, comprehensive and standardised method (ISO 14040 series, namely ISO 14040 and ISO 14044). Life Cycle Assessment (LCA) is a commonly accepted and well-established methodological tool that quantitatively applies life cycle thinking in the environmental analysis of activities related to processes or products. Professionals, decision-makers and investors throughout the European Union (EU) need empirical-based, reliable, transparent and comparable data, based on building performance indicators, to consider impacts related to the whole LC of a building. This sector also generates about one-third of the waste and is responsible for potential environmental impacts resulting from all stages of the Life Cycle (LC) of a building : manufacturing of construction products, building construction, use, renovation and construction waste management.

In the EU, approximately half of all extracted materials and energy consumed and roughly a third of water consumption are due to buildings. It generates almost 9% of the Gross Domestic Product (GDP) and provides 18 million jobs. The construction sector has significant relevance in the European economy.
