This state-of-art multipurpose facility houses  a 1500 seat ice hockey arena, pool, public library, dance studios,  and multi-purpose rooms.

M&R Engineering was responsible for mechanical design including HVAC, Plumbing and Fire Protection as well as electrical design including Lighting, Power, Communications and Security, energy modeling and LEED mechanical and electrical submittals.   

Key Facts:

• Air handling units have energy recovery on exhaust air.

• Full heat recovery is possible from the ice plant for space and ventilation air heating. Excess heat from the ice plant is rejected to a ground loop (geothermal) heat exchanger.

• Geothermal heat pumps provide space cooling along with space heating, pool heating and water heating.

• The ice rink has a low-emissivity ceiling to reduce cooling loads.

• The pool filtration pumps have variable speed drives to reduce energy usage when the filters are clean and over night.

• The pool dehumidification unit rejects heat to ventilation and the pool.

• Pool backwash is sent to the ice melt pit to reduce heating energy.

• The Galleria and Library have an engineered natural ventilation system to save cooling and fan energy when conditions permit.

• Flat plate solar collectors provide heating for the lap pool.

• Embedded bleacher radiant heating provides a more comfortable environment and saves energy compared to conventional heating systems. 

• Variable Speed drives are installed on circulation pumps to save electricity and provide greater control.

• A rainwater harvesting system provides water to toilets and urinals. 

• Occupancy and daylight sensors are installed to reduce lighting power when rooms are unoccupied. 

• Electric vehicle charging stations are installed allowing visitors to charge their vehicle while they visit the facility.

• The energy model indicated 47% Energy savings qualifying for over $500,000 in incentives.
