The building design should be evaluated against the projected climate change environment using the DSY weather file for the 50th percentile in:
Free Running Buildings
- Time period: 2050s
- Emissions scenario: Medium (A1B)
Mechanically Ventilated or Mixed Mode Buildings
- Time period: 2030s
- Emissions scenario: Medium (A1B)
The emissions scenarios are a minimum which can be exceeded should the design team feel that consideration of building occupant risk/sensitivity to overheating is necessary.
