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	47,180,132 Kilowatt-hours	160,978.61 MMBtu
Electricity from on-site, non-combustion facilities/devices (e.g., renewable energy systems)	43,960 Kilowatt-hours	149.99 MMBtu

Stationary fuels and thermal energy, baseline year (report MMBtu):

	MMBtu
Stationary fuels used on-site to generate electricity and/or thermal energy	641,235 MMBtu
Imported steam, hot water, and/or chilled water	0 MMBtu

Total site energy consumption, baseline year:

802,363.60 MMBtu

Baseline year building space

Gross floor area of building space, baseline year:

5,134,218 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, 2012	June 30, 2013

A brief description of when and why the energy consumption baseline was adopted:

This is the baseline we used for our first STARS report.

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	0.19 MMBtu per square foot
Baseline year	0.16 MMBtu per square foot	0.22 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:

15.64

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.
