A review of current and future weather data for building simulation

PublishedThis is the author accepted manuscript. The final version is available from SAGE Publications via the DOI in this record.This article provides the first comprehensive assessment of methods for the creation of weather variables for use in building simulation. We undertake a critical analysis of the fundamental issues and limitations of each methodology and discusses new challenges, such as how to deal with uncertainty, the urban heat island, climate change and extreme events. Proposals for the next generation of weather files for building simulation are made based on this analysis. A seven-point list of requirements for weather files is introduced and the state-of-the-art compared to this via a mapping exercise. It is found that there are various issues with all current and suggested approaches, but the two areas most requiring attention are the production of weather files for the urban landscape and files specifically designed to test buildings against the criteria of morbidity, mortality and building services system failure. Practical application: Robust weather files are key to the design of sustainable, healthy and comfortable buildings. This article provides the first comprehensive assessment of their technical requirements to ensure buildings perform well in both current and future climates.The author(s) disclosed receipt of the following financial support for the research, authorship, and/or publication of this article: This research has been performed in the project COLBE (The Creation of Localized Current and Future Weather for the Built Environment) funded by the EPSRC (EP/M021890/1, EP/M022099/1)
