Whole building energy simulation measures expected energy use (fuel and electricity) based on the building’s geometry, climate, building type, envelope properties, and active systems (HVAC & Lighting). It takes into account the interdependencies of the building as a whole system, so it is a particularly useful way to “keep score” as you work to reduce building energy use.
Green Building Studio® (GBS) is Autodesk’s core whole building energy simulation engine, and powers the analysis in both Revit and Vasari. Green Building Studio is a flexible cloud-based service that allows you to run building performance simulations to optimize energy efficiency and to work toward carbon neutrality earlier in the design process. GBS will help extend your ability to design high performance buildings at a fraction of the time and cost of conventional methods.
Revit supports energy analysis for both conceptual forms and detailed architectural models. Vasari supports energy analysis only for conceptual forms – but the “autozoning” features of Vasari make it a better tool for conceptual energy analysis because it more closely follows industry conventions (ASHRAE).
