"---" indicates that no data was submitted for this field

Figures needed to determine total building energy consumption:
Performance Year Baseline Year
Grid-purchased electricity 137120.69 MMBtu 84903.43 MMBtu
Electricity from on-site renewables 20.33 MMBtu 0 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) 85624.90 MMBtu 72505.60 MMBtu
Total 222765.92 MMBtu 157409.03 MMBtu

Start and end dates of the performance year and baseline year (or 3-year periods):
Start Date End Date
Performance Year June 1, 2016 May 31, 2017
Baseline Year June 1, 2004 May 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):
---

Gross floor area of building space:
Performance Year Baseline Year
Gross floor area of building space 2831126 Gross Square Feet 1445653 Gross Square Feet

Source-site ratio for grid-purchased electricity:

A brief description of the institution's initiatives to shift individual attitudes and practices in regard to energy efficiency (e.g. outreach and education efforts):

Phoenix Cup is a series of competitions aimed at reducing our collective ecological footprint. The competition happens twice a year and lasts for three weeks. In the fall the competition focuses on energy reduction, and in the spring it focuses on waste education. Participants complete weekly checklists to earn points and win prizes. Students and faculty/staff can compete.


A brief description of energy use standards and controls employed by the institution (e.g. building temperature standards, occupancy and vacancy sensors):

Other than residential spaces, all administrative, academic, athletic and dining facilities are scheduled for time of use or occupancy through building automation with set points based on the campus Energy Conservation Policy. During the heating season, space temperatures are targeted at 68°F and between 74° - 76°F during the cooling season during occupied hours. Hot Water (HW) & Chilled Water (CHW) system components (valves, pumps and fans) are proportionally controlled based on building occupancy schedules where Energy Management Sensors read:
1. Room return air temperature, humidity, mixed air temperature, supply air temperature;
2. Fan start/stop, fan status, cfm;
3. VSD status (inlet vane damper position);
4. Static pressure;
5. HW & CHW valve position;
6. Damper positions.
Additionally, boilers and chillers reset operating temperatures based on outside air temperatures (outside air resets).


A brief description of Light Emitting Diode (LED) lighting and other energy-efficient lighting strategies employed by the institution:

LED lighting is now the design standard for all interior, exterior, and pole lighting for all new, renovation and retrofit construction. Projects are under review for feasibility for whole building and partial building re-lamping programs.


A brief description of passive solar heating, geothermal systems, and related strategies employed by the institution:

Four residential buildings, a dining hall and one academic building have solar thermal panels for water heating.
There is a geothermal heat pump system for heating and cooling in the Colonnades Neighborhood.


A brief description of co-generation employed by the institution, e.g. combined heat and power (CHP):
---

A brief description of the institution's initiatives to replace energy-consuming appliances, equipment and systems with high efficiency alternatives (e.g. building re-commissioning or retrofit programs):

Efficiency evaluations are done for repairs and replacements, such as the boilers, heat pumps and water heaters.
