This research aims to quantify the role of low-carbon materials and passive design in reducing whole-life carbon emissions in buildings.
Systematic analysis of CO2 reduction potential for low-carbon materials and passive design strategies in a typical single-family house in Vancouver, BC.
Developed a material inventory covering conventional and low-carbon materials, assessing their effectiveness in substitutions.
Conducted 2380 simulations to evaluate operational carbon impacts of various passive design measures.
Cross-Laminated Timber (CLT) achieved the highest embodied carbon reduction, followed by green concrete and PVC, totaling up to 38.7% reduction.
Passive design strategies collectively reduced operational carbon by 53.6%, with window properties outperforming other measures.
Overall carbon reduction reached 53.8% with optimal material and passive designs combined, totaling 140,235 kg CO2e.
