The Wind Energy Team of the Green Campus Enterprise is focused on preparing a feasibility study for putting a wind turbine on Michigan Tech’s campus. The team has decided on a location at the top of Mt. Ripley, and a 100kW turbine. Currently, the team is completing a financial analysis to determine the payback period on this turbine. The team has used OpenWind software to obtain capacity factors, which provide information on how efficient the turbine will be. These capacity factors are used in conjunction with the cost of energy to complete a cost analysis.
The High Rise Buildings Project was created in 2014 under the initiative of Dave Taivalkoski who asked Green Campus Enterprise if there was an interest in forming a student team dedicated to investigating the annual electricity usage of the DOW Environmental Sciences and Engineering Building. The project was proposed with the intent of identifying a probable cause for excess electrical energy consumption. The project continued until 2018.
Single Use Process Water
The Single Use Process Water team was created in the fall of 2019 and is working to install a chilling system that re-cools the cooling water used in chilling lab equipment so it can be used multiple times. Each year more than 87 million gallons of water are used by Michigan Tech, which costs the University approximately 1 to 1.1 million dollars. By installing this chilling system, the team can reduce the amount of water used by campus.
Several years ago, Green Campus Enterprise was tasked with determining the feasibility of using solar thermal collectors to reduce Michigan Tech’s stationary emissions. The Solar Thermal team was created to work on this project with the goal of calculating the solar thermal potential in the Houghton climate and to look for potential areas of implementation on the Michigan Tech campus. The purpose of a solar thermal system is to harvest the sun’s energy by passing sunlight through a collection system which converts solar energy to heat. This heat is then used to warm fluids for different applications throughout the University and reduce the amount of fossil fuels needed for the heating process.
|Steam Back-Pressure Turbine|
|The steam back-pressure turbine team is determining the feasibility of several different steam back-pressure turbines to be used in the steam distribution system on campus. This system would replace existing pressure-reducing valves with a turbine that will generate electricity while still reducing the pressure. The team is performing financial and feasibility analyses for several turbine variations to determine which would be optimal.|
Great Lakes Research Center Cooling Water Retrofit
Members of the Green Campus Enterprise on Michigan Tech’s campus have designed a system to dissipate excess heat from the Great Lakes Research Center (GLRC) into the Portage Canal. The GLRC currently has a system of dry-coolers to dissipate this excess heat from the building. The new design saves the University about $20,000 a year on electricity needed to run the current dry cooler system, and has a pay-back period of about three years.
