The building has been classed as a medium to high risk, and the 50 percentile a higher probability climate change scenario has deliberately been identified as more appropriate. This is to take into account the current development of actual CO2 emissions worldwide. Current trends already exceed the highest emission scenarios developed by the IPCC in 2006 which again formed the basis for the currently available probabilistic weather data UKCP09. It could be argued that the lower emission scenarios and lower percentiles are already outdated and therefore there is an increased likelihood of more extreme climate scenarios.

Summary
In summary the key climate change adaptation issues are: •
Increase internal temperatures
•
Increased external temperatures
•
High internal gains
•
Changing rainfall patterns
•
Localised air pollution
•
Daylight requirements
•
Increased weather severity
The predominant climate related risks to this project are therefore overheating followed by flooding and storm damage. Following detailed analysis of the building’s exposure to climate change related risks, the 2030, 2050 and 2080 @ 50 percentile with high CO2 emission scenario was chosen.
