Benchmark-based Whole-Building Energy Performance Targets for New Buildings

1. Benchmark-based Whole-Building Energy Performance Targetsfor New Buildings RashmiSahai Sustainability Specialist University of California Office of the President June 18, 2014

2. Reasons to Use Whole-Building Energy Performance Targets • California Energy Code Going to net zero • Validated Baseline • Includes all building loads – including currently unregulated loads • Design targets inform and guide operations • Better integration with climate action goals – provides more accurate prediction of future emissions from campus growth

3. Building Energy Performance Metrics

4. Method • Developed for UC Merced in 1999 • Collected whole-campus energy use and building space data from eight UC and CSU campuses (UC Berkeley, UC Davis, UC Irvine, UC Riverside, UC San Diego, UC Santa Barbara, CSU Fresno, CSU Stanislaus) • This building energy load data correlated reasonably well with climate parameters and with density of buildings containing complex space (e.g., labs) – regression created • Regression equation used to develop climate-adjusted, space-specific benchmarks for all other UC campuses. • Benchmarks adjusted for specific campus infrastructure

5. Benchmarks for Annual Electricity Consumption (kWh/gsf/yr)

6. Benchmarks for Annual Thermal Consumption (therms/gsf/yr)

7. Benchmarks for Peak Electricity Consumption (W/gsf)

8. UC Building Energy Benchmarks by Campus Academic / Administrative Non-complex Space

9. UC Building Energy Benchmarks by Campus Housing Non-complex Space

10. UC Building Energy Benchmarks by Campus Lab/Complex Space
