Total Multi-intervention Cost of Passive Architecture Terraced House

Passive Architecture (PA) Terraced House has been deduced as a likely alternative to a Typical Terraced House, particularly when the former provides favourable indoor environmental conditions for a longer duration compared to the latter. Coupled with Energy Efficient (EE) appliances and Renewable Energy (RE), PA Terraced House saves the Operational Energy (OE) cost for the household. This paper advocates the above actions should be applied collectively for the least Total Multi-intervention Cost (TMC) in the long term. This study demonstrates the TMC for PA Terraced House in comparison with the Typical Terraced House for a 30-year study period. The result shows that the highest TMC for PA Terraced House is lower than the lowest TMC for Typical Terraced House, making PA Terraced House worth the while for household. It also shows that PA Terraced House increases the efficacy of EE appliances and RE system, namely solar photovoltaic (PV), thus closing the economic gap between these items and the conventional ones.
