As the UK braces for another scorching heatwave, experts are raising alarms over new-build homes turning into 'ovens' due to poor ventilation and excessive insulation. With an amber heat alert in place, residents are being urged to take precautions to avoid overheating indoors.
Why New-Builds Are Overheating
Modern construction standards prioritise energy efficiency, often leading to tightly sealed windows and thick insulation. While this helps in winter, it becomes a liability during heatwaves, trapping warm air inside and turning homes into sweltering hotspots.
Key Risks for Residents
- Dehydration and heatstroke: Prolonged exposure to high indoor temperatures can be life-threatening.
- Sleep deprivation: Nighttime cooling is minimal, disrupting rest and health.
- Vulnerable groups at risk: Elderly, young children, and those with chronic illnesses face heightened dangers.
How to Stay Safe
Experts recommend:
- Keeping curtains closed during peak sunlight hours.
- Using fans or portable air coolers where possible.
- Staying hydrated and avoiding strenuous activity indoors.
- Checking on vulnerable neighbours regularly.
The Met Office has issued an amber alert, urging the public to take the heatwave seriously. With climate change increasing the frequency of extreme weather, architects may need to rethink home designs to balance energy efficiency with summer survivability.
