Overheating in Modern Homes: Why Ventilation, Heating & Cooling Matter More Than Ever
As homes become increasingly airtight and energy-efficient, a growing issue is emerging: overheating. While high levels of insulation and airtightness help retain warmth in winter, they can also cause internal temperatures to rise uncomfortably — and sometimes dangerously — during warmer months.
Overheating is no longer a niche concern. Industry guidance, including CIBSE recommendations and the introduction of Building Regulations such as Part O, now formally recognises the risk overheating poses to occupant comfort, wellbeing and productivity. Without the right systems in place, homes can struggle to expel excess heat, leading to poor sleep quality, reduced indoor air quality and reliance on inefficient cooling solutions.
At BPC Ventilation, we provide integrated ventilation, heating and cooling systems designed to directly address overheating — while maintaining energy efficiency and exceptional indoor air quality.
Why Overheating Happens in Today’s Homes
Several factors contribute to overheating in residential buildings:
- Highly insulated and airtight building fabric
- Large glazed areas and solar gain
- Reduced natural ventilation
- Internal heat gains from occupants and appliances
- Rising outdoor temperatures linked to climate change
Simply opening windows is often unreliable, noisy, insecure, and ineffective during heatwaves. Instead, mechanical ventilation combined with intelligent heating and cooling offers a controlled, reliable solution.
Ventilation as the Foundation of Thermal Comfort
Effective ventilation is essential not just for fresh air, but for removing excess heat and moisture. When combined with comfort cooling and heating, modern ventilation systems can actively manage indoor temperatures throughout the year — reducing overheating risk without resorting to traditional air conditioning.
BPC Ventilation specialises in solutions that integrate seamlessly into modern homes, providing comfort, compliance and long-term efficiency.
