RIT Campus Improvements Joe Cooper Dan Crossen Diego Guinea Alex Peterson Mike Walsh
Goals of Primary Stakeholder • Lower RIT’s carbon footprint • Carbon Neutral by 2030 • Lower energy consumptionof all kinds • Improve efficiencies wherever possible • Implement improvements for Ice Arenas • Promote awareness of energy consumption
Stakeholders • Enid Cardinal – RIT Senior sustainability Advisor • Hockey Team & associated parties • Students / Spectators • Building Maintenance • Construction companies • RIT Financial Department
Background Information on Problem #1: Hockey Arena Energy Consumption • Ritter Arena is one of the largest energy drains on this campus • Must keep a sheet of ice frozen 24/7 • Keeping indoor environment at suitable conditions for spectators (Air around 60°F) • Simultaneous heating and cooling can be counter-productive, and waste serious energy. • And how is RIT planning to reduce the overall energy consumption? By adding…
Hockey Arena Data • According to ASHRAE data, hockey arenas consume an enormous amount of energy • Average rink: 1.5 Million kWh/year • Most Efficient: .8 Million kWh/year • Least Efficient: 2.4 Million kWh/year • Some arenas in Canada have reduced their overall energy consumption by 25-50% by lowering the overall temperature of the arena. • There are only 2 LEED certified Ice Arenas in existence.
Problem #2: Emissions Inside the Hockey Rink • The Zamboni, powered by propane fuel, re-surfaces the ice. • Some other zambonis are powered by diesel. • Some college hockey players in other arenas have been hospitalized by the Carbon Monoxide and Nitrogen Dioxide emissions left by the Zamboni’s emissions. • After the Zamboni does it rounds, there have been recorded values of 50+ PPM of CO in other arenas, well above acceptable levels of around 30 PPM.
Problem #3: The Zamboni Ice Pile • Ice dumped in parking lot to melt ~ potential cooling source. • 3 Deposits per hockey event • Complaints/eye sore
Background Research Ice Bear Energy • Stores energy in form of ice. • Improves air conditioning efficiency • Lower cost for electricity at night • Lowers energy usage about 43.2 kW-hrs during the day. • Uses about 32.0 kW-hours at night.
Problem #4: Campus-Wide Energy Consumption Monitoring • Few places on campus monitor their energy use • Only some of the newer buildings • Energy usage monitoring per room and per floor/area is desired so improvements can be made in high consumption locations. • No data showing current electricity consumption • RIT has some plug devices that can be used to do research about outlet energy consumption • Some offices and buildings have movement sensors that help reduce energy consumption.
Energy Consumption • 20% - 30% of the energy is ‘wasted’ due to poor usage • Equipment not used remains plugged to the outlets (‘Ghost Loads’ - Ex. Computer, chargers, etc) • Water at RIT is cheap but there is no monitoring of the water usage except when water comes in and out of the campus. • Lots of water is wasted and this is not yet quantified • Building Temperature: • Energy is wasted in heating or cooling academic and residential buildings because thermostats are poorly located. • Temperature in building need to be uniform to avoid losses. • An ideal temperature in buildings is between 68 and 72 degrees.
Core Concepts for Implementation Courses: • Heat Transfer • Fluid Mechanics • Circuits and Hardware • HVAC
Goals of Secondary Stakeholders • Improve the quality of the Circuits and Electronics lab • Create a ‘project build’ space for engineering clubs on campus • Create an easier way to interface with Student Government • Create an easier way to interface with Papa John’s (for club pizza sales) • Improve and fix known problems with the registration system
Secondary Stakeholders • Nick Hensel • Engineering Clubs (members and officers) • Papa John’s • Student population (registration) • Meghan McDonald (interview scheduled for Monday)
Summary: Possible Areas of Improvement Ice Arena • High energy usage of arena as a whole Zamboni • High indoor pollutant levels (CO,CO2,NO,NO2,etc…) • The Ice pile Monitoring of current “energy hot spots” • Target where energy is being used in order to identify “Ghost Loads” • Unknown usage: Dorms by building, floors, rooms
