Sustainability & Performance

What is Energy Modeling?

Energy modeling simulates how much energy a building design will use, driven by its geometry, envelope, systems, climate, and occupancy. It predicts performance before anything is built and demonstrates code or certification compliance.

In practice

Early-stage tools give designers fast feedback loops (change the glazing, see the load) while detailed models support code compliance and incentive programs. The trend is modeling continuously during design rather than validating after.
