The BIg Mistakes Happen on the First Day

That’s why it’s important to start the energy model early. We have developed a process for creating an early-stage energy model using very basic, conceptual information about a design. We call it an “energy snapshot.” The project manager fills out this spreadsheet about their project and sends it to me:

I input this information into an energy simulation tool such as REM Rate (residential) or eQUEST (commercial) along with some reasonable assumptions based on building systems our firm typically utilizes and a few minutes later . . . An energy model is born.

This model will be refined throughout the design process to include more accurate information (and thus, more accurate results), but provides a snapshot of how the design is performing relative to our 2030 Challenge goals.
