2015 Spring Projects
a. Hand Dryer
The use of paper towels in Humboldt State University’s public restrooms is wasteful, messy, and costly. This project aims to reduce the amount of paper towels consumed by Humboldt State University by installing at least one Dyson Airblade dB hand dryer in each of nine selected high-traffic restrooms. Installing one hand dryer in each proposed restroom will pay for itself in an estimated 2.3 to 4.6 years by reducing the amount of money spent on paper towels, custodial hours, and waste disposal. If all nine hand dryers are installed, the average calculated greenhouse gas emissions reductions will be 4 metric tons of carbon dioxide per year, equivalent to the emissions of burning 9.3 barrels of oil (EPA Energy).
b. LED Retrofit for Science D and the Library
This report proposes an implementation timeline for various light emitting diode lighting retrofit options for the Humboldt State University Library and Science D buildings. The report includes a background of the existing locations and technologies, as well as an energy, cost, and emissions analysis for the alternatives. It is recommended that the 16.5 Watt four foot Philips LED T8 InstantFit Lamps be used to replace all of the existing four foot fluorescent lamps in Science D as soon as possible. It is recommended that these remain for their lifetime unless advanced lighting controls are installed in Science D, at which point it is recommended that the Axlen eZ-series or equivalent retrofit be installed and the Philips lamps repurposed. For the Library, it is recommended to wait until 2018 to commence the retrofit, at which point various Cree LED (detailed below) or equivalent fixtures be installed. It is also recommended that advanced lighting controls be installed in the library to further improve energy savings.
c. Virtual Green Office
Similar to the previously implemented Virtual Green Room project, the Virtual Green Office will serve as a showcase for sustainability in the workplace. The Virtual Green Office will be a highly accessible demonstration informing current and future members of the campus community of the available resources and appropriate behaviors and actions that lead to zero waste, water and energy conservation, alternative transportation, monetary savings, human health, and community building.
d. Dorm Energy Monitoring
It is proposed that the HEIF Committee fund the Creekview Residence Hall Electrical Metering project to educate students about their own energy use and encourage its reduction. By purchasing, installing, and maintaining 48 suite level meters, a kiosk, and a single access point for collected data via a web interface system, students will be able to track and compare their energy use to that of their peers. In conjunction, it is asked that the HEIF form a partnership with the Humboldt State University (HSU) Housing Department and PowerSave to develop new strategies for better engagement in energy reduction competitions that are the key for project success. With success, HSU can gain greater recognition for sustainable practices and for its innovative resolution of energy monitoring in the broader community. With a total expected project lifetime of 10 years, the net present value of the project is $80,184. The project payback period is highly dependent on student engagement in the energy reduction competitions mentioned. Over the project lifetime a ~7% (20,400kWh/yr) average decrease in energy would be needed before project pay back.
e. Building Level Metering
The purpose of this project is to create a more efficient energy monitoring system for Humboldt State University (HSU). This monitoring system will be able to aggregate gas, electricity, and water consumption by each campus building in real time and relay said information into the Johnson Controllers. To accomplish this goal, an array of devices are researched and their prospective connections relative to one another are established. Cost analysis is then executed on three alternatives, all varying in the devices that comprise them. Through the cost analysis, it is determined that to achieve the most cost-effective energy monitoring system, each building should have a Modhopper tranceiver installed to transmit data from each building’s electrical, gas, and water meter into two data acquisition servers, the Acquisuite A8812. This mode of energy monitoring will accrue a cost of approximately of $122,362. The project at hand will serve as a stepping to stone to create a more diverse and accessible energy monitoring system, one that will have the capacity to serve as a tool for learning, system diagnosis, and data collection.
