An energy model is an electronic tool that can predict the energy usage in new and existing buildings. When used in the earliest stages of design an energy model can guide choices about a building’s shape, envelope, and orientation. Modeling contributes to effective HVAC design and can identify a site’s renewable energy potential. Models are necessary for achieving green building certifications and when pursuing the “performance” pathway through the building permit review process. As a trusted resource, Cyclone has provided energy models to clients all across the US.
