UK Homes and Overheating | Designing for Rising Temperatures

From an eco-architecture perspective, the report highlights a reality we are already designing for: overheating in UK buildings is a form-finding and fabric problem, not just a mechanical one.

We believe that before defaulting to widespread air conditioning, the priority should be passive heat reduction strategies embedded in building design: high-performance external shading (brise-soleil, deep reveals, shutters), reduced glazing gains through orientation-sensitive design, and robust thermal mass to dampen daytime peaks. Equally critical is designing for natural cross-ventilation and stack-driven airflow, ensuring buildings can purge heat effectively during cooler night periods.

Urban and landscape-scale interventions matter just as much - tree canopy cover, shaded streets, green roofs, and evaporative cooling landscapes can significantly reduce ambient temperatures before heat reaches the building envelope.

Mechanical cooling may have a role for vulnerable settings, but resilient design should begin with form, fabric, shade, and airflow - not reliance on energy-intensive systems as a first response.
