WHAT IS LIFE CYCLE ASSESSMENT (LCA) FOR BUILDING PROJECTS?
Life Cycle Assessment (LCA) is a standardized, scientifically proven tool for quantifying impacts, with the aim of assessing the environmental impacts throughout the life cycle of a building.
LCA takes into account all stages, from the extraction of raw materials to construction, distribution and use until final disposal. LCA can measure both the impacts of a building throughout its life cycle and, at the same time, quantify the impact of an individual material on the building.
The calculation of greenhouse gas emissions (or carbon footprint) is only one dimension of LCA, which can also assess impacts such as ozone depletion, eutrophication, impacts on human health, and many more. The results obtained through an LCA are reliable as they are based on international standards, ISO 14040 and 14044. This helps ensure consistency, reliability, and independence from commercial pressure.
BENEFITS OF CONDUCTING LIFE CYCLE ASSESSMENT (LCA) FOR BUILDING PROJECTS
Some of the benefits of conducting Life Cycle Assessment (LCA) for Building Projects include:
• Assessment of site installation options, aiming to select the most environmentally friendly one.
• Comparison of the environmental impacts of renovation versus demolition and construction of a new building.
• Comparison of alternative designs to select those with the lowest impacts.
• Identification of high environmental impact materials of a building and taking measures to reduce them.
• Calculation of the environmental impacts of building materials and products throughout their life cycle, helping to choose the most sustainable options.
Obtaining a green building certificate:
Life Cycle Assessment (LCA) of Building Projects is a significant advantage in green building certification systems such as BREEAM, LEED v4, and many others.
Compliance with whole-life carbon regulations:
Governments are increasingly recognizing the need for legislative regulation to reduce whole-life carbon emissions (i.e., operational and embodied carbon emissions) in construction. Life Cycle Assessment (LCA) of Building Projects is a mandatory part of many of the new laws and policies.
Creating cost-effective benchmarks:
Life Cycle Assessment (LCA) of Building Projects can be fully automated using existing design data and fully integrated into the workflow without interrupting or slowing it down. This allows for the cost-effective creation of benchmarks.
Improving transparency:
Customers, investors, tenants, and other stakeholders are increasingly seeking transparency regarding the environmental impacts of a building. Life Cycle Assessment (LCA) of Building Projects is the most reliable and transparent way to achieve this.
Compliance with Scope 3 greenhouse gas reporting requirements
By considering the whole life cycle approach, an LCA can quantify both operational emissions and the impacts of building materials and processes, the so-called Scope 3 emissions required for compliance with many corporate environmental policies.
STAGES FOR LIFE CYCLE ASSESSMENT (LCA) OF BUILDING PROJECTS
With the use of appropriate software (e.g., One Click LCA), the stages for Life Cycle Assessment (LCA) of Building Projects are as follows:
• Design data import: Design data is imported through Building Information Modeling (BIM) or energy models (gbXML) or even through Excel spreadsheets.
• Automatic data conversion: The data is automatically converted into LCA results according to the certification system you have chosen.
• Results analysis: The results are analyzed to identify the most significant improvement opportunities for delivering an even better project.
According to the LCA report, the points with the highest carbon emissions in the building can be directly identified, and intervention can be made for the corresponding corrective actions.
