    Changing thermal comfort expectations: studies in Darwin, Australia
    (NCEUB, 2018) Williamson, T.; Daniel, L.; 10th Windsor Conference: Rethinking Thermal Comfort (12 Apr 2018 - 15 Apr 2018 : Windsor, UK)
    This paper presents an examination of the thermal expectations of occupants in naturally ventilated dwellings from two studies in Darwin, Australia, conducted some 25 years apart (1988/89 and 2013/14). The 25 years between the two studies have witnessed dramatic changes in Darwin, that include a doubling of the population, considerable differences in dwelling styles offered in the market, technological developments making the installation of air-conditioning more available, relative changes in incomes, and energy prices making air-conditioning more affordable. The 1988/89 study employed Comfort Vote Logger devices to record a total of 3800 comfort votes in 16 un-air-conditioned houses during the build-up and wet seasons. The 2013/14 study involved 20 mainly free-running houses in which thermal conditions were recorded on purpose built logging instruments while the occupants recorded 2535 comfort votes over a ten-month period. Analysis presented in the paper gives a detailed comparison of the results from the two studies covering four criteria central to the adaptive comfort concept - external versus indoor temperatures, thermal acceptability, thermal sensitivity and thermal neutrality. The paper concludes with a discussion of the findings and implications of these findings for the adaptive approach to thermal comfort.

    Residential wintertime comfort in a temperate Australian climate
    (NCEUB, 2018) Daniel, L.; Baker, E.; Williamson, T.; 10th Windsor Conference: Rethinking Thermal Comfort (12 Apr 2018 - 15 Apr 2018 : Windsor, UK)
    There is a growing realisation among policy-makers and researchers that Australia has a vastly underrecognised cold housing phenomenon. Overshadowed by the dominance of concern for summer heatwaves and cooling, to date little Australian work has been undertaken on winter housing conditions. In responding to this research and evidence gap, this paper presents the findings from a wintertime thermal comfort field study in metropolitan Adelaide, South Australia between July and October 2017. Participant households were selected from a larger random sample of 4,500 Australian households in the Australian Housing Conditions Dataset (AHCD). Data for this field study was collected from 19 households in the AHCD who self-identified as unable to keep warm in cold weather in their homes. On average, internal temperatures in the sample dwellings were well below standard thermal comfort levels. Interestingly, findings also indicate that residents reported being comfortable at temperatures much lower than accepted norms. Overall however, they reported very low satisfaction with their indoor thermal environment. Several hypotheses are put forward as possible explanations of these findings but will need to be subject to further research. Nevertheless, the findings from this paper position indoor cold as a forefront concern for Australian housing research and policy development.
