A brief description of when and why the energy consumption baseline was adopted:
As directed by the State of North Carolina, FY2002-2003 is the baseline year from which UNCG measures its progress toward achieving energy and water conservation goals.

A brief description of the institution's initiatives to shift individual attitudes and practices in regard to energy efficiency:
UNCG implements both Green Room and Green Office certification programs, which promote a number of energy saving practices. We frequently promote the energy efficiency achievements associated with LEED construction via internal and external communication channels - we have 20 LEED certified buildings on campus. We've developed a Standards of Comfort policy that regulates temperature settings in buildings. We make annual energy and greenhouse gas reports public available on our websites.
A brief description of energy use standards and controls employed by the institution:
As part of the Standards of Comfort program started in December 2011, many buildings on campus follow occupancy schedules programed through controlling temperature during unoccupied hours through upper and lower limit setpoints by the Building Automation System (BAS). Buildings not on the BAS are also being incorporated into this program, as Facilities staff must manually adjust the settings in these non-BAS buildings each season and install thermostat locks to prevent occupants from changing these settings. All of the buildings on campus have a locked thermostat; the University will continue this approach with any new building and or space added.
A brief description of Light Emitting Diode (LED) lighting and other energy-efficient lighting strategies employed by the institution:
Since 2016, the UNCG Green Fund has contributed $73,475 toward 6 LED lighting retrofitting projects totaling 855 bulbs, including outdoor lighting and dormitory emergency lighting systems. The result is an annual savings of 178,058 kWh and $19,644 in avoided utility, parts, and labor expenses. UNCG also participates in the North Carolina Utility Savings Carry Forward initiative (HB1292 / General Statute 143-64.12(a)) and regularly dedicates portions of that funding to LED upgrades, including $140,213 in FY21 for lighting in our Studio Arts building. The University's Weatherspoon Art Museum also received a $100,000+ grant to upgrade to LED lighting in the building. Many buildings have lighting occupancy sensors in offices, bathrooms, and classrooms.

A brief description of the institution's initiatives to replace energy-consuming appliances, equipment, and systems with high efficiency alternatives:
To achieve energy consumption and utilities cost reduction goals, UNC Greensboro focuses first on low or no cost energy conservation measures (ECMs). The HB 1292 Utility Savings Carry Forward (USCF) program is used as a main resource to support energy saving projects.
UNCG started reporting/requesting the USCF credits in FY2011. The USCF funds in 2012 were around $232,000 with no ESCO savings ($7.2 million PC in 2008) since the guaranteed energy savings contract pre-dated the HB 1292 legislation. FY2016 approved/executed funds were $308,068, which increased to $872,169 in FY2021, and to $981,009 carried forward to FY2022. UNC Greensboro plans ahead to get the best of the program and spend the entire USCF amount before it disappears by the end of the fiscal year. In fiscal year 2021, the entire approved/funded was spent down to the last penny.
Utility Savings Carry Forward funds (HB1292 / General Statute 143-64.12(a)) will continue to be used to invest in energy conservation measures to achieve the University and State energy reduction goals. In addition, the fund will back up the Repair and Renovation funds in replacing failed and outdated HVAC equipment with more energy efficient equipment in State-supported facilities. The funds will also support other critical projects on campus such as repairing steam/condensate leaks in the steam distribution system.
