Part 1
This credit is based on energy inputs from offsite sources and electricity produced by onsite renewables. When the institution purchases one fuel and uses it to produce heat and/or power, you should enter only what is purchased. For example, if the institution purchases natural gas to fuel a CHP system and produce steam and electricity, only the purchased natural gas should be reported.
| Performance Year | Baseline Year | |
| Grid-purchased electricity | 45,952.50 MMBtu | 37,496.60 MMBtu |
| Electricity from on-site renewables | 108.10 MMBtu | 31.10 MMBtu |
| District steam/hot water (sourced from offsite) | 0 MMBtu | 0 MMBtu |
| Energy from all other sources (e.g., natural gas, fuel oil, propane/LPG, district chilled water, coal/coke, biomass) | 106,310.50 MMBtu | 134,717.40 MMBtu |
| Total | 152,371.10 MMBtu | 172,245.10 MMBtu |
Start and end dates of the performance year and baseline year (or 3-year periods):
| Start Date | End Date | |
| Performance Year | July 1, 2015 | June 30, 2016 |
| Baseline Year | July 1, 2005 | June 30, 2006 |
A brief description of when and why the building energy consumption baseline was adopted (e.g. in sustainability plans and policies or in the context of other reporting obligations):
This is the same baseline year that was used to report on this credit when HSU submitted its first STARS report in 2013. We continue to use this baseline to track progress in our building energy consumption.
Gross floor area of building space:
| Performance Year | Baseline Year | |
| Gross floor area of building space | 1,995,999 Gross square feet | 1,994,400 Gross square feet |

Optional Fields
A brief description of the institution's initiatives to shift individual attitudes and practices in regard to energy efficiency (e.g. outreach and education efforts):
Green Campus, a program of the HSU Office of Sustainability, coordinates approximately three “Power Down HSU” events each semester, during which the campus community is engaged to conserve energy over a four-hour period and share how they are doing so via social media. Prior to the event Green Campus conducts an outreach campaign to encourage turning off excessive lighting, turning down thermostats and limiting electronics use. To add to the impact, Facilities Management initiates routine demand response measures during the four-hour event. A Power Down event in November 2015 led to 1,466 kWh in energy savings for the campus. To engage campus residents, Green Campus works closely with the Resident Sustainability Advisor to conduct Dorm Energy Competitions. Faculty and staff are engaged through the Green Workplace Assessment, also administered by Green Campus, which awards departments for implementing energy conservation and other sustainability measures.
A brief description of energy use standards and controls employed by the institution (e.g. building temperature standards, occupancy and vacancy sensors):
Facilities Planning & Design works with HEIF funded student teams each semester to develop environmentally preferred building standards that a) are based on the California building code, CSU Lighting Design Guide, and LEED qualifications; and b) provide clear recommendations for relevant products and technologies in the areas of lighting and controls, building materials, furnishings and other attributes. These guidelines are used in accordance Job Order Contract (JOC) specifications.
A brief description of Light Emitting Diode (LED) lighting and other energy-efficient lighting strategies employed by the institution:
Various types and scopes of LED lighting projects throughout the years have resulted in different lighting technologies and output campus-wide, resulting in energy savings with the co-benefits of improved aesthetics and safety. To date, LED lighting has been installed in different parts of Humboldt State University, primarily through small to moderate scale projects (e.g., Fulkerson Recital Hall stage lighting, Reese Bullen Gallery, Dining Services areas, campus-wide screw base change-outs, football stadium scoreboard), but Facilities Planning & Design has made it standard operating procedure to install LED lighting as part of larger interior remodel or refresh projects (e.g., Nelson Hall East) and continues to work with the Humboldt Energy Independence Fund to develop exterior (i.e., street and pathway) LED lighting projects. In January 2017 Facilities Management will replace existing high bay fluorescent fixtures in the Lumberjack Arena (basketball arena) with LED fixtures.
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, e.g. combined heat and power (CHP):
Housing has a 350 kW natural gas engine co-generation plant. Process heat is used to heat a building heating loop that services two residential building complexes and the Jolly Giant Commons (JGC). The plant generates electricity for the JGC and two residential building complexes. When electricity output is greater than usage in these areas, excess goes onto the main campus grid.
A brief description of the institution's initiatives to replace energy-consuming appliances, equipment and systems with high efficiency alternatives (e.g. building re-commissioning or retrofit programs):
Cal State University Executive Order 987 sets energy conservation goals for sustainable building practices and physical plant management, which includes utilizing life cycle costing procedures, instead of first capital cost only, as the basis for equipment selection. When the funding is available, Facilities Management continues to contract with a third party (such as Cogent Energy, kW Engineering) to conduct building re-commissioning, prioritizing buildings where the EUI per square foot is above the CBECS median amount for buildings in in its cohort, and the HVAC equipment and associated energy management and control systems are found to be operating at a sub-optimal level. From 2014-16 CSU Chancellor’s Office-funded monitoring based commissioning projects were completed for Gist Hall, Founders Hall and Science D and E buildings.
