Bradford White Training Facility Raises the Bar

(Continued)

Each ERV/AHU has an energy wheel (air-to-air heat exchanger) in addition to heating and chilled water coils. Air exchanges are done at neutral temperatures, meaning that air into the building is the same temperature as the exhaust air. The VFD-driven ERV/AHU system also handles building air balance, while monitoring carbon monoxide/dioxide levels.

When in the heating mode, waste heat from the live-fire training boilers all work in tandem to provide optimal air temperatures. As the primary heat source, in-floor radiant was used throughout the newly-constructed portions of the building, while hydronic baseboard is installed in the remodeled area.

“We chose portions of the parking area where we would not include snow-melt,” said Bowerman. “It helps to show the effectiveness of the system. In total we have approximately 9,000 lineal feet of 5/8-inch PEX tubing under the sidewalks and main parking areas, served with a BTU load just over 700,000.” Through much of the heating season, this load can be handled by waste heat from the live-fire lab.

Domestic hot water is provided via a solar thermal array that is installed at ground level to allow those not familiar with solar technology to see how it works, up close and personal without having to climb on a roof. The solar thermal indirect tank is in series with a second indirect tank that is connected to the live fire lab loop. If the lab isn’t firing, the NeoTherm boilers can also provide hot water to the indirect fired tank.

Other LEED point features include a four (4) kW photovoltaic array, which has the framework to grow to 20 kW, and a rain water harvest system. Rainwater is collected and we hold 30,000 gallons underground to supply all irrigation water for the landscaping and all gray water for toilets and urinal flushing. All light fixtures, whether indoor or outdoor, use energy-stingy LED bulbs. The TV screens used are also LED.

“We wanted to give contractors, reps and wholesalers the opportunity touch, feel, fix and observe new mechanical equipment in use for more than just making shower water,” continued Bowerman. “After seeing how well courses go here, I’d say we hit this one out of the park.”
