Revit Architecture
Revit MEPPerform energy analysis on conceptual models quickly and easily, before any detailed design work begins.

Create a mass model, define analysis settings, and submit an analysis request over the internet. When an alert appears, the analysis is complete and ready for viewing. You can also display multiple analyses for side-by-side comparisons. Use the analyses to make decisions that move your project towards sustainable design.
Conceptual energy analysis provides early estimates for conceptual models before any detailed modeling occurs. For in-depth analysis of a detailed model, export the model to gbXML and use a third-party application to perform an energy analysis.
