For much of the last century, the design of homes in the UK has focused on the challenge of keeping the occupants warm.

‍Improved insulation, increased airtightness and more energy-efficient construction have helped reduce heat loss and improve winter comfort. However, as our climate changes and summer temperatures continue to rise, a new challenge is becoming increasingly important: preventing buildings from overheating.

Recent periods of prolonged hot weather have highlighted the need to think differently about environmental design. A home that performs well in January must also remain comfortable in July.

‍Factors such as orientation, glazing design, solar gain, ventilation and external shading all influence how a building responds to warmer conditions. Decisions made at the earliest stages of design can have a significant impact on comfort throughout the life of a building.

‍Historically, buildings often relied on passive measures such as deep window reveals, high ceilings, shutters and natural ventilation to moderate internal temperatures. Many of these principles remain just as relevant today.

At Alex Oliver Associates, we seek to incorporate these passive design principles into our projects from the earliest stages of the design process. Careful consideration is given to building orientation, the arrangement of rooms, natural daylight, solar gain and ventilation strategies to help create comfortable homes that respond to both their site and the changing climate.

Addressing overheating should not be viewed as an afterthought or something solved solely through technology. Thoughtful architecture can reduce reliance on mechanical cooling, improve comfort and create homes that are better equipped to respond to our changing climate.

Sustainability starts with good design.

Designed for a private client, this innovative passive house is carefully positioned within the unique setting of a disused lime quarry. The building’s form was meticulously planned to respond to the sun’s path, allowing southern light to flood the interior while the highly insulated northern façade, with minimal glazing, reduced heat loss. The curved, linear design followed the natural contours of the quarry, stepping gracefully into the landscape.
