We will use a method already published by the team together with the UKCP09 weather generator to produce current and future typical weather at a resolution of approximately 5km.
The work in the previous work package will initially require the creation of thousands of years of weather per site. Within these initial years will reside a large number of weather events of interest to the building scientist or engineer. These files will be used in computer models of 1200 differing architectures and building uses to identify what are the key drivers of weather variable coincidence that defines the likelihood of building system failure or thermal issues for occupants.
Having characterised which events best describe the stresses on a building, its occupants and systems in WP2. Event years (i.e. times series of weather data variables on a one hour time step that represent atypical hot, dry, cold and wet periods) will be created for the whole UK.
Having generated the event years, and simulations from the 1200 buildings, the two will be recombined to produce the first map of UK resilience to a changing climate. Although others have looked at the regional resilience of the built environment using average weather years, the concern is not about the response of building and occupants to such average time series, but to more extreme events.
Given the large number of files proposed, guidance will need to be given on which to use in practice, and how this might be expressed in the building regulations and other documentation.
We plan to use case studies as the main guidance tool. This will add greatly to their intellectual validity within the target audience of practicing engineers. In total, we expect the guidance to be tested on >100 real building projects
All weather files produced by the project will be publicly available for a minimum of 10 years. A series of road shows will be undertaken at the end of the project. At these events the results of the project will be presented to a large number of users. The idea will be to introduce the whole UK built environment community to the idea of designing resilient buildings aided by the weather data produced by the project. A short film will also be produced for those that cannot attend and for an international audience.
