View of the sports and health center

A new addition to the Sports and Health Center, completed in 2006, was built with energy efficiency in mind.

Upgraded HVAC systems help save energy. Variable frequency drives match the volume of air moved to the system demand. The system in the newer addition of Sports and Health is controlled via time-of-day scheduling, ensuring that air handling systems are matched with building occupancy hours.

UMD's fitness center lit up by natural light and high efficiency bulbs

Fitness and training areas are lit with natural light; additional high-efficiency fluorescent lighting fixtures were also installed.

Pervious pavement outside of SPHC

Pervious pavers were tested outside of Sports and Health as a stormwater management technique, allowing water to filter through pavers to slow it down. More recently, pervious pavement has been installed near the loading dock at the Civil Engineering building.

UMD Ice Rink

Energy efficient lights adorn the ice rink interior. On the exterior, a white roof on the building helps reduce energy used for cooling the space.

In 2010, the ice rink floor and cooling loops were replaced to improve ice quality and reduce greenhouses gases through elimination of refrigerants in the cooling loops under the ice.

The old rink floor was made of steel pipe embedded in concrete and coils filled with hydrochlorofluorocarbons, a refrigerant otherwise known as R-22. The new system will have fusion-welded poly pipe in a new concrete slab. Waste heat from chiller compressors heat glycol that circulates in the floor heating system, which helps to prevent permafrost. This will stop future cracking and breaking of the concrete slab due to permafrost heaving in subsurface soils.

The new system will eliminate use of R-22 in the rink floor. While R-22 is still needed in some parts of operation, the total amount used is reduced by 89%. The in floor system will run glycol instead of R-22, which is a powerful greenhouse gas that is accounted for in UMD’s carbon footprint calculation. More information and statistics are available on this poster.

Romano Gym

Energy efficient lighting in Romano gym

The Romano gym was retrofitted with high–efficiency fluorescent lighting. The fans and controls in the gym were also upgraded to reduce ventilation when not being used  in order to save energy.

A new pool pack system combines air exchange and humidity control functions, saving energy, water and the building’s interior.

UMD Field House

The Field House on UMD’s campus was retrofitted in 2013. Bulbs and fixtures were swapped with more energy efficient lighting and the controls were modified to have better scheduling. More details coming soon!
