Designing For Natural Ventilation
- Use passive or natural ventilation systems where possible
- Maximising daylight to reduce the need for electric lighting
- Using blinds and coatings on glazing to reduce summer gains
- Specifying the most efficient small power equipment
- Placing high heat-emitting equipment in dedicated areas with separate ventilation, or on the north side where heat gains are easier to overcome
- Windows to be opened by users where practicable
- Use a zero ozone depletion potential (ODP) if an air conditioning system has to be used
- Use reflective materials to minimise the need for cooling
- Breathing wall construction may provide filtered ventilation for the building
