29.43 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 219,969,648 Kilowatt-hours 750,536.44 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 475,782 MMBtu
Imported steam, hot water, and/or chilled water 0 MMBtu

Total site energy consumption, baseline year:
1,226,318.44 MMBtu

Baseline year building space

Gross floor area of building space, baseline year:
13,050,001 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, 2013 June 30, 2014

A brief description of when and why the energy consumption baseline was adopted:
Energy baseline was adopted in order to align with the baseline used in the university's Sustainability 2020 Plan goals regarding greenhouse gas reduction.

Source energy

Source-site ratio for imported electricity:
3

Total energy consumption per unit of floor area:
Site energy Source energy
Performance year 0.08 MMBtu per square foot 0.17 MMBtu per square foot
Baseline year 0.09 MMBtu per square foot 0.21 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:
20.90

A brief description of the institution's initiatives to shift individual attitudes and practices in regard to energy efficiency:
In collaboration, USC Housing and Facilities Planning & Management (FPM) have sponsored dorm energy efficiency competitions. This has been a great way to educate students and boast participation in energy saving efforts. For several years USC has participated in LADWP's Demand Response program. In order to ensure successful participation, the Energy Services team proactively reaches out to building users to explain the process, participation, and its importance. Subject Matter Experts have presented at bi-annual sustainability forums to discuss ongoing projects and how students, staff and faculty play a role in energy efficiency efforts. Finally the team has created a public dashboard so that the community can actively understand the university's electricity usage in real time (https://buildingos.com/s/usc/portfolio/?chapterId=40473).

A brief description of energy use standards and controls employed by the institution:
USC has a robust set of controls that allow for a high level of management across almost 170 buildings. Honeywell EBI is used to manage set points and monitor temperatures.

USC’s centrally-managed climate control system ensures consistent energy monitoring and temperature control throughout every building connected to the system. In summer 2018, USC piloted a program that can schedule Heating, Ventilation, Air Conditioning, and Cooling (HVAC) system shutdowns in classrooms when they are not in use, and test results exceeded expectations. The Events2HVAC scheduling software was purchased and now is in use at 18 buildings, 237 classrooms, and 40 air-handling units. Through this program, we’re registering energy savings at or above projected levels. In one month alone, this project saved more than 42,000 kWh. The program is projected to extend to an additional 259 classrooms.

A brief description of Light Emitting Diode (LED) lighting and other energy-efficient lighting strategies employed by the institution:
Over the last three years FPM has launched an LED Retrofit Program across 29 buildings, retrofitting more than 33,000 fixtures. These retrofits are expected to save >6M kWh a year and thus the projects are an important element to achieving USC's Assignment: Earth goals.

Data source(s) and notes about the submission:
USC has continued to drive forward the Energy Audit and Retro-commissioning program that aligns with City of LA's EBEWE program. In total approximately 150 buildings will be completed every 5 years. Over the last three years, approximately four audits and RCx reports have been completed a year. The effort also includes pursuing Energy Star Certification. The university now has 8 Energy Star certified buildings CEN, FMT, HIL, SIE, TSA, TAP, TRE/TRH, and FSA.
