As awareness of the urgency of the climate crisis grows, efforts to kickstart en masse deep energy efficiency interventions are gathering apace. But poorly conceived low energy building efforts can lead to unintended consequences including overheating – a risk that’s bound to grow as the world warms up. Phi Architecture co-founder Claire Jamieson details the risks and offers some solutions on how to create low energy buildings that are comfortable in summer and winter.
Cement is responsible for up to 8% of global carbon emissions, and in this guide, sustainable design expert Jay Stuart looks at ways to minimise its environmental impact through good design, and at some of the alternative, lower carbon cement and concrete products on the market.
In the first in a new series of technical articles on some of the key technologies in sustainable building, John Hearne makes the case for wrapping buildings in an external insulation layer, and describes some of the main issues to watch out for.
Heat recovery ventilation is an invaluable way to maintain indoor air quality in low energy buildings and minimise the loss of precious heat, but there are several issues to address to ensure optimal performance. Ventilation expert Ian Mawditt, a technical advisor on Part F of England’s building regulations, has decades of experience in field investigations of indoor air quality and ventilation effectiveness. His guide, which focuses on centralised or ducted whole house heat recovery systems, is essential reading to anyone considering such a system.
