A brief description of when and why the building energy consumption baseline was adopted:
---
None
A brief description of any building temperature standards employed by the institution:
We use a building automation system to schedule HVAC run times in most general University buildings. The University has included both occupied and unoccupied temperature ranges for building temperatures within our energy management guidelines.
None
A brief description of any light emitting diode (LED) lighting employed by the institution:
Lighting in the communicating staircase in the HBRC building is LED as is the decorative lighting in the public elevator lobby of the building. Also LEDs light the entry way in Taylor's Dining Room, the lounge in Willard Hall, conference room of Whitehurst Hall and the Wes Watkins Center. Outdoor LED lighting has been employed along Farm Road and Monroe Street and is scheduled to be installed in all outdoor fixtures.
None
A brief description of any occupancy and/or vacancy sensors employed by the institution:
We have lighting automation systems as part of our larger building automation system in our most recent new construction and renovations. In our OADDL Lab building, occupancy sensors are used to control HVAC and air flow rates so that life safety needs are met while maximizing energy efficiency.
None
A brief description of any passive solar heating employed by the institution:
Passive solar heating is employed on campus in these buldings: Noble Research Center atrium, ATRC atrium, the Colvin Annex, and Architecture building south hallways.
None
A brief description of any ground-source heat pumps employed by the institution:
The Colvin Center Annex and Mechanical Engineering Petroleum Lab employ ground-source heat pumps and they are currently being installed as part of the new Vet Med offices now under construction.
None
A brief description of any cogeneration technologies employed by the institution:
Steam extraction turbines at OSU Central Plant produce both heating steam and electricity.
None
A brief description of any building recommissioning or retrofit program employed by the institution:
In 2014 Oklahoma State University implemented smart lab technologies within the Henry Bellmon Research Center (HBRC) with the introduction of a trio of comprehensive energy saving mechanisms such as an Aircuity OptiNet Facility Monitoring System, Zone Presence Sensors (ZPS) for lab fume hoods, and a Demand Control Ventilation (DCV) System. After this recommissioning project, the HBRC is now able to efficiently provide conditioned air requirements by means of tracking and trending the occupancy patterns in labs and common shared spaces while continuously adjusting and modulating HVAC appropriately to specific parameters to ensure that indoor air quality is safe and healthy for all.
None
A brief description of any energy metering and management systems employed by the institution:
We employ a building automation system that controls HVAC run times and related associated equipment. We also have real-time energy consumption data on some electric, steam and most chilled water usage locations. This allows for real-time decision making both in production and usage spheres.
None
A brief description of the institution's program to replace energy-consuming appliances, equipment and systems with high efficiency alternatives:
OSU is an ENERGY STAR Partner with the U.S. Environmental Protection Agency. Our Building Energy & Environmental Standards require that we meet Energy Star designation. In October, 2013, OSU received a large rebate from our electricity provider, OG&E, for upgrading to more energy-efficient equipment in the West Chilled Power Plant. The upgraded equipment resulted in lowering kilowatt usage, OSU uses Technology Based Contracts, to replace old equipment.
None
A brief description of any energy-efficient landscape design initiatives employed by the institution:
Outdoor LED lighting has been installed on two major streets on campus, Farm Road & Monroe, and is being planned for the rest of outdoor space throughout campus.
None
A brief description of any vending machine sensors, lightless machines, or LED-lit machines employed by the institution:
As part of our recent energy efforts, all soda vending machines, regardless of locations, had Vending-Miser installed which reduced run-time based on an occupancy sensor.
None
A brief description of other energy conservation and efficiency initiatives employed by the institution:
The OSU Energy Management Program employs behavior-based energy management techniques to engage all staff, faculty and students in the University's goal to continue to lower its energy usage.
None
