Cold New Zealand Council Housing Getting an Upgrade

Abstract

As people spend most of their time at home, residential thermal conditions are important. Central government debate about minimum temperature requirements for rental properties requires an evidence base of indoor temperature data. We collected temperature, humidity and energy data from 49 council housing dwellings in Wellington over winter, and self-reported thermal comfort and heating behaviour. Mean indoor temperature was 14.9°C, colder than the national average, with 67% of readings under 16°C, which the World Health Organization associates with health implications. With New Zealand’s high rate of excess winter mortality and children hospitalised for housing-related diseases, cold housing should be addressed.
