Drawing on evidence from a mixed methods retrofit intervention trial of the homes of low-income, older and frail people in Victoria, Australia, this study explored practices of heating and keeping warm in terms of equity and health. In most homes, heating restrictions led to inadequate indoor temperatures. Adaptation practices increased householder resilience, however, some technical responses presented safety risks. Low-cost retrofits did not eliminate underheating and had little effect on householder practices.
This report presents outcomes from a three-year mixed method evaluation of the Department of Health and Human Services’ low-carbon housing in Horsham, Victoria. The aim of the project was to conduct a multi-year evaluation of four new two-bedroom, single-storey, sustainably designed units with a National House Energy Rating Scheme (NatHERS) rating of 8.9 stars (Catalyst houses), in addition to seven one- and two-bedroom Control dwellings (located in Horsham).
