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 88,474,698 Kilowatt-hours 301,875.67 MMBtu
Electricity from on-site, non-combustion facilities/devices (e.g., renewable energy systems) 146,102.40 Kilowatt-hours 498.50 MMBtu

A brief description of the institution's initiatives to shift individual attitudes and practices in regard to energy efficiency:
The University has strategic goals as part of a climate action plan found here:
https://president.uoregon.edu/university-oregons-updated-climate-action-plan

A focus on energy in particular asks of the institution to consider the following:
"Conduct several studies that will inform decision-making so that we target our energy and resources where they can have the most impact. These studies will investigate: how we will plan long-term to heat campus using low carbon energy sources; internal carbon pricing to explore potential revenue sources that can fund direct emissions reductions on campus; the costs and carbon-reduction impacts of a campus-wide LED retrofit; alternative commute options to lessen the impact of our faculty, staff, and students traveling to and from campus; and the feasibility and impact of a winter break “turn down” and temperature set-point policy to shrink our energy consumption."

UO has completed a feasibility study to transition away from natural gas for thermal power and is currently in the process of deliberation on this study.

A team of Sustainability Ambassadors has been monitoring building energy use, measuring heat and lighting ensuring that building uses are reduced during evening hours. Ambassadors are also providing labs information on unclosed vent covers, or 'sashes', as part of a 'shut the sash' campaign. The findings are reported on a weekly basis to building occupants as both data gathering and accountability mechanism encouraging users to make the best choices in energy use reduction.

The SCORE program provides home energy audits and evaluation. This encourages positive behavior actions on the part of recipients. The SCORE program can be found here: https://cpfm.uoregon.edu/score

Public education also offers all students, faculty, and staff thermometer magnets ('thermagnets' for short) which can be applied to an office refrigerator or to the side of a desktop CPU. These allow the office to see in real time the ambient temperature in the used space and control their thermostat accordingly. This is a very popular tool which allows offices to better prepare themselves to make the choice of energy reduction.

As part of the Green Office Certification, personal space heating and energy use are metrics in the point system of the certification process. Each department is required to coordinate with the system HVAC controllers at the building level. By asking building occupants to consider their impact and the best methods of achieving personal comfort this impacts personal use decisions in every participating office.

This is a sampling of current projects.

A brief description of energy use standards and controls employed by the institution:
The University maintains a process of continuous improvement in energy management found here: https://cpfm.uoregon.edu/sites/cpfm2.uoregon.edu/files/uo_em_semp_fy20_final_0.pdf . Although this document is the most recent version however, it is no longer current and a new version is in development plan will be released when updated.

The University uses centralized steam/chilled water to heat and cool campus buildings. The centralized control allows for optimized energy management, see the the Campus Planning Facilities Managements, UO Energy Management Program here: https://cpfm.uoregon.edu/utilities-energy/energy-management

Buildings on campus use timers to regulate temperature, for example Lillis hall uses a central computer to measure inside and outside light levels and temperature, building occupancy, heating load, and power generation and adjusts controls automatically for maximum efficiency. The Oregon Model of Sustainable Development (OMSD) requires all new and renovated spaces over 10,000 gsf are required to be built to LEED Gold, which requires commissioning and performance spec evaluation. OMSD: https://sustainability.uoregon.edu/PDF/principle_10_sustainable_development_2021.pdf
As a result of the OMSD energy consumption on campus has remained relatively flat while significant square footage and whole new buildings have come online as is observable on the Sustainability dashboard:
https://sustainability.uoregon.edu/energy.html

"Over the past 5-years Campus Services/Facilities/Utilities has initiated use of strategic energy management planning (SEMP) to achieving significant levels of energy savings. This approach is based on the understanding that SEMP is a successful and well-established practice used by many large educational institutions throughout the country, and has proven to be one of the most successful means of improving management of opportunity risk and cost associated with utility use."- https://cpfm.uoregon.edu/utilities-energy/energy-management

A brief description of Light Emitting Diode (LED) lighting and other energy-efficient lighting strategies employed by the institution:
Campus Planning and Facilities Management implemented a campus-wide LED lighting improvements for safety and efficiency in 2017. See an article about this here: https://around.uoregon.edu/content/brighter-nights-ahead-campus-adds-more-led-lighting

According to the the Oregon Model of Sustainable Development (see point 1 of the Comprehensive Sustainability Plan here: https://cpfm.uoregon.edu/Policy-Sustainability ), all new construction projects over 10,000 sqft are built to LEED Gold standards. LEDs and efficient lighting design are key elements in energy reduction. Use of LEDs is extremely common in newer buildings however, existing infrastructure continues to maintain fluorescent lighting until renovation or lighting updates can occur.

The UO has implemented a lighting retrofit revolving fund (pp.61 - SEMP: https://cpfm.uoregon.edu/sites/cpfm2.uoregon.edu/files/uo_em_semp_fy20_final_0.pdf ). The projects selected for this fund must reduce overall energy costs. Projects must demonstrate a payback period of five years or less.

A brief description of passive solar heating, geothermal systems, and related strategies employed by the institution:
According to the the Oregon Model of Sustainable Development (see point 1 of the Comprehensive Sustainability Plan here: https://cpfm.uoregon.edu/Policy-Sustainability ), all new construction projects over 10,000 sqft are built to LEED Gold standards.

Many building employ thermal massing, and passive energy management strategies. Shade shields are common on campus to allow windows and natural light, but reduce afternoon heat accumulation inside buildings during warm periods. Many buildings use passive cooling and night cooling strategies. UO is also a registered arboretum and frequently large campus trees are incorporated into the design of buildings to assist with shade and cooling (see the Campus Plan Principle 2, Open Space Framework, here: https://cpfm.uoregon.edu/campus-plan)

A brief description of co-generation employed by the institution:
The UO has a natural gas combine cycle co-generation system which is not currently economical to use as prime-power generation. Current use is limited to operation for maintenance, testing, and training.

A brief description of the institution's initiatives to replace energy-consuming appliances, equipment, and systems with high efficiency alternatives:
The University maintains a standard for desktop and laptops. Staff may choose from a small range of options all of which achieve energy efficiency standards. Most modules are EPEAT certified.

Data source(s) and notes about the submission:
For the stationary fuels and thermal energy baseline, we included the fuels consumed to generate heat and electricity in buildings. We excluded 512,687 therms (51,268 MMBTU) of 'other campus uses', which consist of decorative fire places, lab use, and kitchens. The emissions from the other fuels are tracked internally and included in the total scope 1 GHG emissions.

The UO has five buildings that generate PV solar electricity: our Facilities Warehouse (10.5KW), the Erb Memorial Union (10KW), the Student Recreation Center (12.6KW), Outdoor Program Barn (5.3KW), and EC Cares facility (5KW).
