Designing out domestic overheating risk in challenging urban environments

Climate change, intense urbanisation and air tightness (without sufficient ventilation) of new and existing homes in order to meet energy efficiency standards have in the recent years increased the risk of overheating in homes. The assessment of overheating is now an important element in the design process in order to find a balance between energy efficiency and comfortable living spaces. This session will look into the challenges of achieving this balance in urban environments where noise, air pollution and security concerns can limit the use of natural ventilation.
