Life Cycle Assessment (LCA) has become an invaluable tool for evaluating the environmental impact of construction projects. However, its application in the complex landscape of the construction industry is not without challenges and limitations. Data availability- and quality, varying file formats, and many other factors make the field of LCA complex and difficult.
The importance of addressing data availability and quality cannot be overstated. The reliability of LCA outcomes hinges on the accuracy and comprehensiveness of the data used in assessments. Finding innovative solutions and tools to navigate through these challenges is imperative to facilitate change toward more sustainable practices in the construction industry worldwide.
One size does not fit all
The intricate nature of construction projects, characterized by a web of interconnected processes, materials, and stakeholders, introduces a formidable challenge to accurate modeling and quantification of environmental impact. The industry's diversity in construction methods, materials, and project scales adds another layer of complexity, making it challenging to standardize LCA processes across diverse projects. Establishing standardized methodologies with appropriate categories of environmental impact, allocation methods, and functional units is essential to ensure consistency and comparability in LCA assessments, as different approaches can yield varied results.
Stakeholder involvement and effective communication also pose challenges in LCA implementation in construction. Construction projects involve a multitude of participants, including architects, engineers, contractors, and suppliers. Ensuring collaboration and cooperation among these diverse stakeholders, especially when they have varying levels of awareness and commitment to sustainability practices, can be a significant challenge.
Finding ways to bring everyone together and establish the right standards to ensure consistency in methodology, process, and data collection would provide great value to all parties involved, and especially help improve the availability and quality of environmental impact data.

Data availability and quality
A major obstacle lies in the limited availability of reliable and comprehensive data for construction projects. The absence of standardized databases for environmental impact data creates a significant hurdle, hindering the acquisition of accurate information for various materials and processes. Incomplete or outdated data further amplifies the challenge, potentially leading to skewed LCA outcomes.
The lack of high-quality data that is up-to-date is a persistent issue in LCA implementation. Construction projects often span extended periods, during which materials, manufacturing processes, and environmental regulations can undergo significant changes. This dynamic nature of the construction industry contributes to the difficulty of maintaining an updated and comprehensive dataset for conducting LCA.
The impact of poor data reverberates throughout the entire LCA process. Inaccurate or incomplete data can lead to skewed assessments, compromising the validity of the environmental impact results. Decision-makers, who rely on LCA outcomes to guide sustainable practices, are significantly impacted when the data used in these assessments is unreliable or insufficient. This compromise in data quality can potentially result in suboptimal decisions and unintended environmental consequences.
Furthermore, the absence of standardized databases and quality assurance of data causes challenges in comparing LCA assessments across different construction projects. Not having access to a consistent baseline of reliable data hampers the ability of stakeholders to benchmark environmental performance. This in turn makes it harder to identify best practices and impedes progress toward more sustainable construction practices.
Could increased regulation improve standardization?
A way to solve, or at least alleviate these obstacles, could be a combination of consolidating and standardizing databases into curated, publicly accessible ones, and introducing requirements for all involved industries to collect and submit data to them. This could be facilitated by similar ISO standards to the ones that already form the foundation of LCA methodology, or with the help of EU directives, for example. This would undoubtedly be a lengthy process, however, and it could take years to initiate and follow through.
Whatever the solution may be, it’s not likely to come overnight. In the meantime, the industry may therefore have to rely on software technology that eases collaboration and data collection throughout the entire construction process.
Anavitor LCA
Anavitor LCA includes features that facilitate seamless communication and data sharing among different project participants. By connecting to various local databases of environmental data, and making use of the Environmental Product Declarations (EPD) of manufacturers, the Anavitor LCA achieves greater data accuracy when assessing the environmental impact of construction projects.
Two-way integration between BIM and LCA
One of the main advantages of Anavitor LCA is its two-way integration between BIM and LCA. By bridging the gap between these, the accuracy of LCA increases, and it becomes easier for stakeholders to make informed decisions on ways to improve the sustainability and carbon footprint of a project.
sbXML compatibility
Anavitor LCA can handle and extract data from sbXML files, ensuring interoperability with other software that utilizes the format. This is especially useful during the actual construction phase, where it’s more common to encounter sbXML-based software tools.
