This paper reports on the development of a methodology utilising a mixed-method approach to evaluate IEQ in residential homes – green and conventional.

There are claims to the superior indoor environmental quality (IEQ) of green buildings in comparison with similar conventional ones, making them more attractive buildings to people given the time they spend indoors. A review of the literature reveals little empirical evidence to substantiate such claims, especially for residential buildings. The few research studies that focused on residential buildings used less comprehensive methods and evaluated fewer IEQ aspects than the ones focusing on other types of buildings.

To address these limitations, this research reports on the development of a comprehensive methodology using a mixed-method approach to evaluate IEQ and occupants’ satisfaction in green and conventional homes. The methodology consists of physical measurements of IEQ (i.e. thermal comfort, air quality, acoustics, and lighting), field observations, an occupants’ survey, and interviews with key members of the building design team and facility managers. The proposed methodology will be piloted to a green and conventional home with the aim of validating it before it’s deployed on a wider scale to a much larger sample of conventional and green homes. This pilot study is expected to demonstrate the reliability of the methodology, given its reliance on objective (i.e. IEQ physical measurements) and subjective (i.e. survey and interviews) research methods.
