A discussion paper reframing domestic cooling as both a climate-adaptation and energy-system challenge, with a seven-level hierarchy for meeting legitimate household cooling needs while managing access, electricity demand, refrigerants and heating electrification.
Overview
This discussion paper reframes domestic cooling as both a climate-adaptation challenge and a wider housing and energy-system issue. It separates two questions that are often collapsed into one: whether a household’s need for cooling is legitimate, and how that need should be met.
The paper develops a cumulative seven-level hierarchy, beginning with urban planning, building design and retrofit, then moving through operational measures, ventilation, air movement and active cooling. The hierarchy is not a simple ranking. It recognises that earlier measures may help without being sufficient, and that households differ sharply in the options they can influence or afford.
The analysis also examines unequal access to cooling, the role of reversible heat pumps, compatibility with heating electrification, electricity demand, hot-weather peaks and refrigerant impacts. Its central argument is that responsible adaptation neither makes active cooling the default nor treats it as a failure. Instead, it helps households reach a sufficient response while reducing avoidable environmental and social costs.
