Heating Up, Cooling Off: Managing summer heat flows in Aotearoa New Zealand homes
Kimberley O'Sullivan has received a Marsden Fund Council grant from Government funding to conduct research on New Zealanders’ summertime home energy use as the country adapts to a warming climate.
Six of New Zealand’s top ten warmest years occurred between 2010 and 2019, and increasingly frequent and severe heat days will feature in our future climate. But how do New Zealanders manage summer heat flows in their homes? Current evidence suggests households are turning to mechanical cooling. How might we need to challenge these evolving energy behaviours to curb summer emissions and energy demand in Aotearoa?
This innovative mixed methods research, administered by the Royal Society of New Zealand, is a three-year study which will combine data from a survey, multigenerational interviews, temperature and humidity dataloggers, and energy-use diaries to form recommendations for householders and policy on sustainable practice for summer heat management.
Aims and Objectives
This research employs a multi-phased, sequential, mixed methods design to investigate how New Zealanders manage summer heat flows at home, and how this has changed over time. The goal is to describe in depth the present situation, identifying any shift towards using active cooling that is suggested by minimal current evidence on heatpump use, and ultimately to provide recommendations to households and policymakers that will support sustainable energy use.
- To understand how New Zealanders currently manage summer heat and thermal comfort at home
- To understand the drivers of change in summer heat flow management at home
- To explore home cooling practices and how these may have changed within and between families over time
- To integrate data from a postal survey, multi-generational family interviews, temperature and relative humidity data loggers and energy-use diaries to richly describe the energy cultures of summer heat flow management at home in Aotearoa
- To provide evidence-based recommendations to policymakers and householders based on the energy cultures identified that will support sustainable energy use and community resilience to summer heat in Aotearoa
- To disseminate the results of this critical research through a mix of academic and public engagement outputs
This study will provide ‘storied’ accounts, as well as quantitative and environmental data, to give a broad picture of how households manage summer heat at home across Aotearoa, which is critical for providing relevant advice to householders and policies across the energy, building, and urban development domains. The results of this novel study are expected to be of national and international interest as we move towards a just energy transition in a changing climate.
Summer 2021/2022 has arrived with unsurprising forecasts for above average temperatures across Aotearoa New Zealand. We’re getting ready to launch our postal survey in regions that regularly experience heat extremes for the first stage of our data collection. If you receive a postcard and survey pack from us, please complete our survey to help tell us how you manage summer heat at home and if you choose we can send you a $20 supermarket voucher. We’re looking forward to getting our first insights into how you keep cool at home in summer Aotearoa.
