Projected climate change environment

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.
