Figures needed to determine total building energy consumption:
Performance Year | Baseline Year | |
Grid-purchased electricity | 18,372.98 MMBtu | 21,007.70 MMBtu |
Electricity from on-site renewables | 49.10 MMBtu | 49.10 MMBtu |
District steam/hot water (sourced from offsite) | 0 MMBtu | 0 MMBtu |
Energy from all other sources (e.g., natural gas, fuel oil, propane/LPG, district chilled water, coal/coke, biomass) | 44,680.49 MMBtu | 52,856.61 MMBtu |
Total | 63,102.57 MMBtu | 73,913.41 MMBtu |
Start and end dates of the performance year and baseline year (or 3-year periods):
Start Date | End Date | |
Performance Year | July 1, 2017 | June 30, 2018 |
Baseline Year | Jan. 1, 2005 | Dec. 31, 2005 |
A brief description of when and why the building energy consumption baseline was adopted (e.g. in sustainability plans and policies or in the context of other reporting obligations):
The 2005 baseline was adopted because that's when the Center for Sustainability at Aquinas was established, and energy conservation was elevated in the institution's priorities.
Gross floor area of building space:
Performance Year | Baseline Year | |
Gross floor area of building space | 776,097 Gross square feet | 593,574 Gross square feet |
Source-site ratio for grid-purchased electricity:
3.14
Total building energy consumption per unit of floor area:
Performance Year | Baseline Year | |
Site energy | 0.08 MMBtu per square foot | 0.12 MMBtu per square foot |
Source energy | 0.13 MMBtu per square foot | 0.20 MMBtu per square foot |
Percentage reduction in total building energy consumption (source energy) per unit of floor area from baseline:
34.10
