"The mission statement of this project is to develop several solutions to improve the campus at the Rochester Institute of Technology.
Mission Statement
We were charged with reducing the carbon footprint of RIT’s hockey arena.
However, our project is slightly different than most other projects.
We were given resources, but not a pre-determined project
Common Theme:◦ “It would be nice if you could…”
Project Summary
1. Reclaiming waste heat from the Hockey Arena Pumps.
2. Using waste cooling to pre-treat air for air conditioning.
3. Using the ice pile outside the hockey arena to pre-treat air for Air Conditioning.
4. Using the ice pile outside the hockey arena to cool pipes in the pump coolant loop.
5. Reducing the overall emissions of the hockey arena.
Our Projects
RIT Campus Improvements Wasted water usage Objective Tree
Our mission is to modify and/or add to the current ice rink.
Use the chilled water (@32°F) and the warm
water (@65-90°F) to cool/heat another system in order to
recover any lost energy
Cost Objectives
User Objectives
Design Objectives
Operational Objectives
Remove cost of heating/cooling water
Reduce energy usage in both systems
Use waste heat/cold in another system
Reduce energy usage / energy waste
Modifications must be sustainable (green)
Low carbon footprint
Aesthetically pleasing
Maintain effective running conditions
Low maintenance
Sustainable low day-to-day energy usage
Recover lost energy
Can be integrated into current system
Keep cost of modifications less than money saved

Semi-warm water leaving pumps/entering cooling towers at 65-90° F and leaving cooling towers/entering pumps (for cooling) at 45-55°F
Cold water leaving pumps/entering underslab (for warming of ground)at 36° F and leaving underslab/entering pumps at 32°F
Currently, these two systems do not interact, other than through the pumps. However, the semi-warm water is only used to cool the pumps, and does not come into contact with the cold water at all.

RIT pays to cool down this water from 65°-90°F to 45°-55°F while…
…in the next room, we pay to heat up this water from 32° to 36°F
They are on two separate loops, never coming into contact, and energy is wasted moving their temperatures in opposite directions.

System Overview: Using Waste Heat for Heating
Take the output of this system (65-90°F)
And take the output of this system (32 °F)
And put them through a heat exchanger to utilize the waste heat/cold from one system to heat/cool the other system

System Overview: Using Cooling for Air Conditioning
Currently, there is an ice pile outside of the Ritter Arena made from the zamboni’s resurfacing of the ice rink.
Our customer would like to use the ice for cooling of some system in the ice rink.
The customer referred to it as “The Most Expensive Ice in the World”, unless we were to use it to make one of these…
The Ice Pile: Projects 3 & 4
RIT Campus Improvements Ice Pile Objective Tree
Our mission is to modify and/or add systems to lower
energy consumption by utilizing a “free” source (Zamboni ice
pile for cooling purposes)

Ice Pile for Pipe Cooling (continued)
Zambonis, powered by gasoline, diesel, or propane, are the second major source of emissions in hockey arenas after CO2 emissions from the crowd
Ritter Ice Arena is equipped with four air handlers- three to ventilate the arena and one to dry the air
Currently, only CO2 is monitored, and the building is kept positively pressured to keep down levels of other emissions
System Overview: Reducing Emissions of the Ice Arena
Currently, CO2 levels are measured on one of the four air handlers in the arena
CO2 levels can get very high during games due to the number of spectators if ventilation is not increased
In the past, before installation of computer controls, the Zamboni driver could flick a switch where the vehicles are parked to increase the ventilation while running
Current Emissions Monitoring
Objective TreeRIT Campus Improvements Emissions Monitoring Objective Tree
Our mission is to monitor the level of emissions inside the ice rink and decrease the concentration if it
becomes too high
Cost Objectives
User Objectives
