Overheating in residential buildings is a real problem. UK Building Regulations, Approved Document Part O provides guidelines to help designers mitigate and reduce overheating effects.
Combining ventilation with active cooling can offer a low-carbon solution to these issues and can be designed using dynamic thermal modelling.
Zehnder Group UK is an expert in overheating. Its flagship solution, the Zehnder ComfoAir Q600 with ComfoClime, uses tempered-air technology to address overheating, making it perfect for new builds contending with environmental obstacles like security, noise pollution or lack of shade – ideal when passive means can’t be used to control internal temperatures.
The system integrates heating, cooling, and ventilation functionalities, adhering to Part O/TM59 standards across a range of settings, from residential to care homes. Its innovative features, notably a reversible heat pump module, guarantee energy-efficient performance.
Its use of the lower GWP refrigerant R32 within an efficient, sealed cycle minimises environmental impact and remains compliant after 2025. The first on the market to achieve this.
Seamlessly integrated into building projects, effectively streamlining overheating concerns, Zehnder introduced this cooling approach over 15 years ago and continues to evolve and develop the product to make it the best on the market to tackle residential overheating.
