ANALYSIS OF EMBODIED CARBON CALCULATION FOR MECHANICAL AND PLUMBING SYSTEMS BASED ON INTERNATIONAL STANDARDS

This report provides an example of the calculation of embodied carbon for a research facility that has achieved 『ZEB』, based on international standards, specifically for air conditioning and plumbing systems. The result of the embodied carbon calculation for air conditioning and plumbing was 5.82 kg-CO2e/m2year, or 12.8% of the total embodied carbon of the building. Refrigerants also accounted for a large share, 69.8%, of the total EC for air conditioning and plumbing. To provide example to be compared, embodied carbon calculations were also performed for general buildings.
