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.
