It was an absolute pleasure to deliver a lecture to the talented students and working professionals of the British Columbia Institute of Technology in Canada.
We would like to extend our heartfelt gratitude to Rohit Sharma and Meredith Hannen-Tugwete for extending the invitation to us.
Interacting with such a vibrant and curious audience was truly inspiring.
Thank you for the opportunity, and We hope to collaborate again soon.
A Whole Building Life Cycle Assessment (WB-LCA) was conducted for a commercial office space building in India using the LEED v4 tool of the One Click LCA software. The building had 11 floors above grade and 2 basements, with an area of 35820 m2. The building, referred to as the "proposed building," was compared to a similar "baseline building" in terms of six impact categories.
Global Warming
Ozone Depletion
Acidification
Eutrophication
Tropospheric ozone
Nonrenewable energy
The proposed building was found to have a 10% reduction in three of the impact categories: Global Warming Potential, Tropospheric Ozone Formation, and Non-Renewable Energy Depletion.
Baseline Building Result:-
Proposed Building Result:-
The use of ready-mix concrete with 25% fly ash content and AAC blocks with 65% fly ash content in the proposed building was identified as the factor leading to this reduction. The service life of both the proposed and baseline building was considered to be 60 years, and the same life-cycle assessment software and data sets compliant with ISO 14044 were used for the assessment.
This report was prepared by Essential India Pvt. Ltd. for a hospital project in Vancouver, Canada. It contains Whole Building Life Cycle Assessment (WB-LCA) results as per LEED v4 standards. A baseline and three design options were analyzed, with only the concrete materials being changed in the design options while keeping other materials the same as the baseline. The objective of the analysis was to compare the impact of six categories in all options and determine which option meets the LEED v4 requirements. The LEED v4 requires that a life-cycle assessment of the project's structure and enclosure be conducted and that a minimum of 10% reduction compared to a baseline building be demonstrated in at least three of the six impact categories (Global Warming Potential being mandatory) without increasing the remaining categories by more than 5%. The WB-LCA was conducted using the LEED v4 tool of One Click LCA.
Baseline Result
Result Option 1
Result Option 2
Result Option 3
The results showed that only Option 3 met the LEED v4 WB-LCA requirements, with a 10% reduction compared to the baseline in four impact categories: Global Warming Potential, Acidification, Tropospheric Ozone Formation, and Non-Renewable Energy Depletion. This design option will help the project achieve WB-LCA credits under LEED v4.
