19.70 Btu / GSF / Degree-Day (°F)

Part 2. Reduction in source energy use per unit of floor area

Baseline year energy consumption

STARS 2.2 requires electricity data in kilowatt-hours (kWh). If a baseline has already been established in a previous version of STARS and the institution wishes to continue using it, the electricity data must be re-entered in kWh. To convert existing electricity figures from MMBtu to kWh, simply multiply by 293.07107 MMBtu/kWh.

Electricity use, baseline year (report kWh):
kWh MMBtu
Imported electricity 123,292,102 Kilowatt-hours 420,672.65 MMBtu
Electricity from on-site, non-combustion facilities/devices (e.g., renewable energy systems) 127,000 Kilowatt-hours 433.32 MMBtu

Stationary fuels and thermal energy, baseline year (report MMBtu):
MMBtu
Stationary fuels used on-site to generate electricity and/or thermal energy 826,363.30 MMBtu
Imported steam, hot water, and/or chilled water 0 MMBtu

Total site energy consumption, baseline year:
1,247,469.28 MMBtu

Baseline year building space

Gross floor area of building space, baseline year:
7,963,454 Gross square feet

Baseline period

Start and end dates of the baseline year (or 3-year period):
Start date End date
Baseline period July 1, 2011 June 30, 2012

A brief description of when and why the energy consumption baseline was adopted:
Facilities Management suggested FY12 as a baseline because that was the oldest data that for which they could verify accuracy.

Source energy

Source-site ratio for imported electricity:
3.14

Total energy consumption per unit of floor area:
Site energy Source energy
Performance year 0.14 MMBtu per square foot 0.25 MMBtu per square foot
Baseline year 0.16 MMBtu per square foot 0.27 MMBtu per square foot

Metric used in scoring for Part 2

Percentage reduction in total source energy consumption per unit of floor area from baseline:
6.68

Optional Fields 

Documentation to support the performance year energy consumption figures reported above:
---

A brief description of the institution's initiatives to shift individual attitudes and practices in regard to energy efficiency:
We send out energy conservation emails to the entire campus community each December. We hold various energy efficiency events for students during the year (varies year to year). We have energy conservation tips on several webpages.

A brief description of energy use standards and controls employed by the institution:
All renovated or newly built spaces will include complete metering for performance tracking and optimization. The University standard is now for a Building Automation System that includes occupancy sensors and room and building set backs.

All of our newly constructed buildings have lighting controls integrated with our Building Automation System to better allow the team to manage and maintain lighting efficiency and optimization in our buildings.

A brief description of Light Emitting Diode (LED) lighting and other energy-efficient lighting strategies employed by the institution:
LED lighting is the standard for interior and exterior lighting in all Ohio University buildings. Many older, less efficient lighting systems on campus have been upgraded to LEDs. Most LED lighting in building projects is connected with lighting control systems.

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

A brief description of co-generation employed by the institution:
We do not have co-generation on campus.

A brief description of the institution's initiatives to replace energy-consuming appliances, equipment, and systems with high efficiency alternatives:
Within several buildings on campus, we have replaced steam with heating hot water systems for building heat. We've made efforts to move away from centralized domestic hot water distribution to more efficient local domestic hot water production. We continue to explore the use of heat pumps for simultaneous heating and cooling, such as air conditioning and re-heats.
