Figures needed to determine total building energy consumption:
Performance Year Baseline Year
Grid-purchased electricity 407,673 MMBtu 420,365.70 MMBtu
Electricity from on-site renewables 276 MMBtu 100 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) 757,288.60 MMBtu 826,363.30 MMBtu
Total 1,165,237.60 MMBtu 1,246,829 MMBtu

Start and end dates of the performance year and baseline year (or 3-year periods):
Start Date End Date
Performance Year July 1, 2016 June 30, 2017
Baseline Year July 1, 2011 June 30, 2012

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):

Facilities Management suggested FY12 as a baseline because that was the oldest data that for which they could verify accuracy.


Gross floor area of building space:
Performance Year Baseline Year
Gross floor area of building space 8,348,057 Gross square feet 7,963,454 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 0.14 MMBtu per square foot 0.16 MMBtu per square foot
Source energy 0.24 MMBtu per square foot 0.27 MMBtu per square foot

Percentage reduction in total building energy consumption (source energy) per unit of floor area from baseline:
9.44

Degree days, performance year (base 65 °F / 18 °C):
Degree days (see help icon above)
Heating degree days 4,295 Degree-Days (°F)
Cooling degree days 1,192 Degree-Days (°F)

Floor area of energy intensive space, performance year:
Floor Area
Laboratory space 241,795 Square feet
Healthcare space 28,764 Square feet
Other energy intensive space

EUI-adjusted floor area, performance year:
9,268,794 Gross square feet

Building energy consumption (site energy) per unit of EUI-adjusted floor area per degree day, performance year:

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):

We are always looking for opportunities to reduce carbon emissions, maintenance issues and operational costs (energy).


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

All renovated or newly built spaces will include complete metering for benchmarking performance. The University standard is now for a Building Automation System that includes occupancy sensors and room and building set backs. Our sequence of operations for our HVAC system includes water and air temperature reset schedules to optimize outside air temperatures.

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 - and exterior lighting.


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. 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, 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):

We are replacing steam with heating hot water for building heating systems. We are exploring the use of heat pumps for simultaneous heating and cooling, such as air conditioning and re-heats.
