Kalamazoo College was in need of creating a fitness center that would ‘bring healthy activities for the entire campus community together under one roof,’ by providing dedicated space for multiple fitness programs and activities that were previously scattered throughout campus.
The facility includes:
PBA provided MEP engineering design services for the 30,000 square foot facility dedicated to fitness and wellness which included the incorporation of unique air handling units. The air handling units (AHU’s) are VAV air to air plate and frame energy recovery units (ERU). Each ERU is fed by chilled water and hot water. Chilled water is delivered to the ERU's from an air-cooled magnetic bearing (Mag) chiller. The state-of-the-art chiller is one of the most efficient on the market. Hot water for heating is delivered by highly efficient condensing boilers that supply 130-degree hot water. At the 130-degree supply water temperatures the boilers operate at the 90 to 95 percent efficiency. Demand ventilation was utilized that adjust building ventilation based on actual occupancy.
Domestic hot water was provided to the building by a series of natural gas-fired instantaneous hot water heaters. The instantaneous water heaters provided superior burner turn down which resulted in nearly full modulation. The domestic water heaters delivered 120-degree F domestic hot water in lieu of a storage tank-type system which requires a water storage temperature of 140 degrees F. The overall instantaneous domestic water system produced domestic hot water to the building 30% more efficiently than conventional domestic hot water systems.
In lieu of LEED certification, Kalamazoo College students provided LEED-like auditing in the design, energy and sustainability criteria that inform LEED certification.
“For years to come, this building will represent energy efficiency, sustainability, educational innovation and hands-on learning, as well as health and wellness.”
