The role of thermostats and human behaviour in residential temperature settings in the USA
摘要
Thermostat management is crucial in maintaining safe indoor temperatures. Here we analyse factors that influence thermostat settings in US households during daytime and nighttime hours, with a focus on thermostat type, occupant behaviour, and socio-economic and socio-demographic characteristics. Recommended indoor settings range from 64–75 °F (17.8–23.9 °C) in winter and 75–80.5 °F (23.9–26.9 °C) in summer. For context, data show average daytime thermostat settings of 70.1 °F (21.2 °C) in winter and 72.1 °F (22.3 °C) in summer. Regression results reveal households that manually adjust their thermostat or set it to a single fixed temperature maintain less-efficient temperatures than those relying on smart thermostat automation—up to 2.3 °F (1.3 °C) warmer in winter and 2.2 °F (1.2 °C) cooler in summer. Racial disparities are also evident: Black households set temperatures up to 2.2 °F (1.2 °C) higher in winter and 1.4 °F (0.78 °C) lower in summer than white households. Expanding access to smart technologies and educational initiatives related to thermostat management may improve efficiency and thermal equity.
