Due to its small size, this project used the Small Buildings Method for SB 2030 compliance. This method involves meeting a prescriptive set of requirements and evaluating operational energy use in comparison with an SB 2030 Standard based on those requirements. No design model is required for this method of compliance.

 

Weather Normalization
This graph shows the project’s energy use intensity (EUI), measured in kilo (1,000) British Thermal Units per square foot per year (kBtu/sf/year). It shows the project-specific SB 2030 Energy Standard, the predicted EUI from the project’s energy model, and the actual annual EUI from meter readings (if available).
