Project Overview
Lake-effect snow can lead to severe storms, but Calvin never cancels class!
Michigan receives ≈ 72 inches of snow annually

Project OverviewProblems with the Burton St. Entrance to Calvin
Intersection is dangerous to plow during the daytimeSafety for Pedestrians and Vehicles
Maybe a snowmelt system would be a good solutionWhat kind of snowmelt system?
Conventional Snowmelt systems typically near buildingsConventional systems also rely on fossil fuels.
Why not use Geothermal energy? Some electric energy is used to move energy from the
earth to the desired surface.This would mean a green solution to the problem with
really low operating costs. Let’s check it out!

Project OverviewPrimary Goal: To design and give a
recommendation for a geothermal snowmelt system at Calvin’s Burton Street Entrance (learn)
Secondary Goal: To design and construct a small model to demonstrate the operation of a geothermal snowmelt system
