What is an asset model in energy simulation?

An asset model in energy simulation refers to a whole-building energy simulation that uses standardized conditions to evaluate the energy performance of a building. This approach allows for a consistent and comparable assessment of energy efficiency across different buildings or projects because it simulates how the building would perform under idealized, controlled conditions, rather than specific usage patterns or variations in occupancy and behavior.

The use of standardized conditions ensures that the results are more systematic and can be reliably used in performance benchmarking, policy analysis, or when preparing for certifications such as LEED. By focusing on the inherent characteristics of the building—such as its thermal envelope, heating and cooling systems, and insulation—it helps stakeholders identify potential improvements and understand the overall energy performance in a clear and quantifiable manner.
