The Topic
Research on warming and extreme heat points to much larger cooling demand, higher electricity use, and heavier adaptation pressure on buildings and grids, while heating demand declines in some colder regions.

Summary
- Projected warming to 1.5C to 2.0C is linked to a large expansion in extreme-heat exposure by 2050.
- Cooling demand is expected to rise faster than heating demand falls, especially in warmer and densely populated regions.
- Air conditioning adoption and electricity load are likely to increase, raising pressure on grids and peak-demand management.
- Building decarbonisation and efficiency improvements are presented as key responses alongside heat adaptation.
- The research uses climate-model-based degree-day mapping to translate warming into planning-relevant demand shifts.
- Colder countries are expected to see some reduction in heating needs, but that effect is smaller than the cooling increase globally.
