Episode notes
Buildings Amplify Heat Risk
- Buildings cause most heat-related deaths because occupants cannot escape indoor overheating during heatwaves.
- David Coley warns architecture can turn heat into a lethal risk, citing Paris 2003 fatalities.
Regulation Lags Behind Overheating Risk
- Current UK building design does not require predicting indoor temperatures during heatwaves for new homes.
- David Coley says that regulation lags behind climate change, leaving many new buildings unassessed for overheating.
Provide Secure Night Ventilation
- Ensure safe night-time ventilation pathways to cool buildings when possible.
- David Coley highlights that inability to open windows at night prevents essential cooling for vulnerable occupants.
