A brief description of the institution's initiatives to shift individual attitudes and practices in regard to energy efficiency:
NMSU has a full-time Facilities Sustainability Manager to drive education and initiatives related to energy efficiency. This is collaboration between NMSU, City Agencies and private entities to host informational events.
A brief description of energy use standards and controls employed by the institution:
A temperature set point standard of 70 degrees heating and 76 degrees cooling is in place on buildings tied to the energy management system. Design guidelines are in place to incorporate occupancy sensors on lighting systems. An energy performance contract was completed in 2016 that included the installation of HVAC direct digital controls and installation of variable frequency drives on air handling units and water circulating pumps.
A brief description of Light Emitting Diode (LED) lighting and other energy-efficient lighting strategies employed by the institution:
We have a policy in our Facilities and Services Electric Ship that whenever lamps need to be changed we use LED lamps to replace them.
Working with Project Engineering and Development we upgrade lighting to LED's whenever possible for energy conservation during a remodel or upgrade.
An energy performance contract was completed in 2016 which included high efficiency lighting retrofits in approximately 25 buildings. Parking lot and exterior building lamps were converted to LED as part of this project.
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:
Co-Generation is basically producing two forms of energy from one. In our case we use natural gas as the fuel to power a turbine whose spinning shaft turns a generator and produces about 50% of the electricity for the campus.
The hot (1200 *F) exhaust gases from the turbine enter a water tube boiler and produce steam, which is used to drive a steam driven centrifugal chiller, heat the campus buildings, domestic hot water and swimming pools.
