Weather Design and Data
Posted : April 28, 2010 by Richard Quincey, Category: Sustainability, software
Recently I have been looking at the weather data we use for dynamic simulations using the Gaia rapid analysis tools. When you consider what we used 10 years ago these datasets are a huge increase in resolution, but ….
The attached graphic shows a Mahoney analysis (this looks at monthly trends) of the CIBSE current & climate change weather files for London; you can easily see the progression over time in the climate …. the change in heating and cooling degree day data (HDD & CDD) and the increasing summer season is stark …. but there are inconsistencies in the data, the 2050 data being a case in point.
Overall this should be sufficient cause for building professionals to at least carry out a risk analysis on the robustness of their designs for + 50-80 years hence i.e. the correct fundamental form plus the ability to adapt, but we must accept that the data we use is much closer to the raw edge of science than it ever used to be and it will evolve with the science !
