Passive House Design
Passive House Design: A Summary
Passive House Design is a revolutionary approach to sustainable architecture that prioritises energy efficiency and environmental conservation. Here’s a breakdown of its core principles:
- Orientation: Buildings are ideally positioned to optimise solar exposure, minimising energy consumption for heating and lighting.
- Shape: The proportions and form of a building are designed to minimise heat loss and maximise solar gain.
- Insulation: Thicker building envelopes with high-quality insulation reduce heat loss and energy consumption, contributing to long-term energy savings and environmental preservation.
- Layout: Efficient space planning ensures optimal use of space while minimising energy usage for heating, cooling, and lighting.
- Services: Mechanical Ventilation Heat Recovery (MVHR) systems are essential for maintaining indoor air quality and reducing energy demand for heating and cooling.
- Fenestration: Thoughtful design of windows and doors maximises natural light and ventilation while minimising heat loss and energy consumption.
- Solar Shading: Strategic placement of shading elements helps regulate indoor temperatures and minimise overheating during summer months.
- Triple-Glazing: High-performance triple-glazed windows and doors contribute to the overall energy efficiency of the building envelope.
- Air-tightness: Maintaining airtightness is crucial for reducing heat loss and ensuring energy efficiency throughout the building’s lifespan.
- Cold Bridges: Effective insulation and detailing of building junctions prevent heat loss and minimise the risk of condensation and mould growth.
In conclusion, Passive House Design offers a comprehensive framework for creating energy-efficient, environmentally sustainable buildings. By adhering to these principles, architects and designers can create spaces that not only meet the needs of occupants but also contribute to a greener, more sustainable future.

In 2024 our Director (Andy Wilde) was asked to lecture to architecture students at Salford University in Manchester about Passive House Design.
