The simulation software works by enacting a mathematical model that provides an approximate representation of the building. One of our energy modelers inputs data to create the building model, including weather, building orientation, geometry, constructions, occupant schedules, and energy-using equipment. The calculation engine solves equations rooted in thermodynamics and building science. A single whole-building simulation can take seconds to hours to run, depending on the level of detail and complexity in the analysis.
Results are typically reported for annual performance and include the space cooling and heating loads, daylighting impacts, equipment energy use, resource consumption, energy costs, and other performance-related parameters. This information can help designers make better informed, cost-effective decisions that improve the performance and reduce the environmental impact of buildings.
