House Energy Efficiency Inspections Project

Date

This study investigated new house construction around Australia to gain insight into the quality of house construction with regard to the energy efficiency aspects of air‐tightness and quality of installation of insulation and heating/cooling ductwork and involved recruiting 20 houses in each capital city around Australia (Darwin was not included).

It followed concerns raised that the energy efficiency features of houses that are required to achieve the minimum energy efficiency standards in the National Construction Code (NCC) (Australian Building Codes Board, 2015) were not delivering assessed benefits For example where insulation and weather sealing is poorly installed by builders houses will have lower energy efficiency performance than expected. This filled a gaps in research with little data previously collected on newly built houses to quantify air‐tightness and assess the quality of installation of insulation and heating/cooling ductwork.
