Advances in simulation techniques and computing power, coupled with more progressive goals for decarbonization in buildings, have propelled urban-scale simulation to the fore over the past decade. (1) An unprecedented amount of information is available describing construction, 3D massing, equipment, and even occupants of today’s buildings, all of which is useful in determining which buildings may be the most suitable for certain types of energy retrofits and estimating the potential impacts. Most of this data exists in the public domain (such as property assessment records, building permits records, LIDAR height maps, street-level photographs of building facades, etc.), but is contained in disparate, oftentimes unstructured datasets. Through the development of its platform for large-scale BEM-based analysis of single-family homes, XeroHome has developed data pipelines associated with these sources to establish the best possible basis for building energy analysis and modeling that one can achieve with publicly available information.
This webinar provides a tour through the most valuable public data sources and an overview of features relevant to building professionals that can readily be extracted from such data. (2) We use results from a field demonstration with Southern California Edison to illustrate how these techniques and XeroHome’s simulation capabilities have been applied to evaluate single-family homes in Santa Monica, California for deeper energy efficiency and zero net energy evaluations.
