Butte Station Audit
The aim of this project is to "green up" the "least energy efficient building on campus". By identifying potential savings through an energy audit in the small station on campus known as Butte Station, recommendations will be proposed, and the possibility of retrofits can be explored. A recent campus-wide assessment conducted by PG&E and Facilities Management has identified Butte Station as the least energy efficient building (per square footage) on campus. Butte Station is run by AS Dining, and is known to have inefficient, “open-style” refrigeration that stays on even when the station is not open for business. Our PowerSave Campus team recognizes the opportunity for improvement and will provide auditing, as well as suggestions on where operations can improve. The experience gained by identifying potential savings will help develop our auditing skills for similar projects in the future. For costly expenses such as nightshade retrofits, or automated on/off timers, the team will look to source funding from opportunities such as rebate programs and the Chico State Sustainability Fund. The result will be quantifiable, actual savings, in support of our university’s sustainable reputation.
Outdoor Lighting Retrofit
The objective is to create actual energy savings by retrofitting outdoor lighting with new bulbs. The first step is surveying the areas on campus that we believe have the potential to improve energy efficiency. The next step was mapping the locations of each light post in the two chosen areas. From there, day time images of the bulbs and lamps will then be used to help Facilities Management identify the bulb types. We will also use an infrared thermometer and a foot-candle meter to determine properties of the different bulbs, such as radiant heat and luminescence. After collecting data for the current bulbs, it can be analyzed to help find more efficient alternatives. It will then be necessary to allocate funding for our proposed upgrade and installation. We intend to pursue a diverse range of funding opportunities, from SFAC, The Green Initiative, rebates from PG&E, our own rebate pool from past projects, and possibly partnering in a pilot program. Once we receive the funding, bulbs can be purchased, and the retrofit will be completed after the installation. Savings will add up every night when the outdoor lighting kicks on.
Plumas Hall Compressor Audit
On the CSU campus hidden from obvious view are a multitude of labs where students are able to obtain hands-on experience within their fields. As a Sustainable manufacturing major, one of our members’ labs often consist of dirt, grime, and lots of mechanical equipment, including electrical saws, lathes, furnaces, and welding supplies. All of this equipment is accompanied with a troublesome sound...the sound of energy being wasted. Upon entering the labs during off-hours, when all is quiet and students aren't grinding away at their work, a "hiss" lingers off in the distance. This hiss is from potential leaks somewhere along the line system between the compressors and the majority of tools in the labs that they supply air to. The mission is to evaluate the compressor system in Plumas Hall to identify leakage from broken/unmaintained air hoses and provide energy savings by fixing leaks or updating parts.
Vending Machine Audit
The goal of this project is to develop a greater understanding of the energy consumption of the vending machines on campus, and to find ways to decrease their overall footprint on campus. A comprehensive understanding of the campus’ vending situation will allow for informed and targeted energy saving measures to be implemented. Such methods could include “motion sensor” installation, elimination of machines that are rarely used, outdated, containing irresponsible items such as bottled water, or machines that refrigerate items unnecessarily. The project starts by obtaining more information on the vending machines from AS Dining Services and the third party vendor they contract. Once we know more about the contracts of the machines, their stocking schedule, and individual energy use, we can implement a plan to reduce their consumption of energy.
