7.85 Btu / GSF / Degree-Day (°F)

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	40,954,340 Kilowatt-hours	139,736.21 MMBtu
Electricity from on-site, non-combustion facilities/devices (e.g., renewable energy systems)	0 Kilowatt-hours	0 MMBtu

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

	MMBtu
Stationary fuels used on-site to generate electricity and/or thermal energy	58,589 MMBtu
Imported steam, hot water, and/or chilled water	0 MMBtu

Total site energy consumption, baseline year:

198,325.21 MMBtu

Baseline year building space

Gross floor area of building space, baseline year:

2,202,861 Gross square feet

Baseline period

Start and end dates of the baseline year (or 3-year period):

	Start date	End date
Baseline period	June 7, 2018	June 7, 2019

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

Baseline was from our first year reporting to STARS.

Source energy

Source-site ratio for imported electricity:

Total energy consumption per unit of floor area:

	Site energy	Source energy
Performance year	0.04 MMBtu per square foot	0.10 MMBtu per square foot
Baseline year	0.09 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:

53.23

A brief description of the institution's initiatives to shift individual attitudes and practices in regard to energy efficiency:

UNG prides itself on building automation systems that a majority of our buildings employ. This system adjusts set points based on occupancy and usage. We also built out two solar arrays on our Gainesville campus. This new system generated 89,558 KWh its first year. This system is also being used as a teaching/research tool for our faculty. We have plans to expand the use of solar.

A brief description of energy use standards and controls employed by the institution:

On many of our campus buildings, we are using automated building controls to turn off lights and reduce heating/cooling loads during "unoccupied mode". We hope to continue to install these controls as well as conduct retro commissioning on older buildings. We are also strategically replacing older, inefficient light fixtures with LED fixtures to reduce energy loads, especially in areas where lights are on long hours throughout the day/night. All of these types of projects are typically awarded when extra funds are made available.

A brief description of Light Emitting Diode (LED) lighting and other energy-efficient lighting strategies employed by the institution:

As stated above, UNG is replacing many older, inefficient light fixtures with LED fixtures to reduce energy loads, especially in areas where lights are on long hours throughout the day/night. When building new spaces or during renovations, all lighting is LED when possible.

A brief description of passive solar heating, geothermal systems, and related strategies employed by the institution:

We paid an engineering firm to explore the use of a geothermal system for our new business school building but the size would be too large to be cost effective. We may still consider its use on future projects.

A brief description of co-generation employed by the institution:

---

A brief description of the institution's initiatives to replace energy-consuming appliances, equipment, and systems with high efficiency alternatives:

This replacement occurs during renovation projects or when funds are available. We make use of Georgia Power's Rebate Program that provides money to offset replacements with energy efficient ones.
