The Kent County 63rd District Court.

This state of the art 40,000 square foot facility will utilize a closed loop Geothermal heat pump system with fifty (50) vertical Geothermal wells used for heating, air conditioning and ventilation. Forty (40) ground source heat pumps and one (1) roof mounted water-cooled heat pump energy recovery unit serve the building. The telecommunication/server room is served by a dedicated computer room air conditioning unit with a steam humidifier. The prisoner's sally port was equipped with a sidewall exhaust fan that is interlocked with a carbon monoxide detection system. All four (4) entrances to the courthouse are served with in-floor radiant heat.

Thousand Oaks

The design/build construction project at Thousand Oaks incorporated the renovation of the existing restaurant/pro shop and a 25,000 sq ft expansion of the existing banquet facility. A geothermal loop field, complete with forty-five vertical bores, was installed under the new parking lot. The existing mechanical system was eliminated and twenty-three (23) geothermal water source heat pumps were installed to provide heating and cooling needs to the space. Eight (8) of the geothermal water source heat pumps also serve the domestic hot water, perimeter radiation, and snow melt systems. Twelve (12) energy recovery units serve the buildings ventilation air and exhaust requirements. Three (3) walk-in cooler/freezer boxes and refrigeration were installed for the expanded needs of the kitchen. The system was designed and constructed to meet LEED certification.

Founders Brewery

Founders Brewery was a design/build project that consisted of an existing truck terminal that was renovated into a new restaurant & bar. The restaurant is served by a horizontal packaged heating and cooling unit that is mated to an energy recovery ventilator that provides conditioned ventilation air to the space. A two-story office area is served by a high efficient furnace and condensing unit. Attached to the bar is the brew house where two (2) packaged rooftop units provide the space heating, air conditioning, and ventilation air needs. A cooler expansion project was later installed and consisted of a 38,000 cubic foot drive-in cooler refrigeration system. The refrigeration system has (2) warehouse evaporator coils, designed to keep product packaging from deteriorating due to moisture, and a packaged commercial Bohnimizer outdoor unit with a semi-hermetic compressor and headmaster low ambient controls.

The Fitzgerald

This historical renovation known as The Fitzgerald, consisted of thirty-nine (39) custom designed condominiums. A water source heat pump system with an open loop cooling tower was utilized for the heating, air conditioning, and ventilation system. A total of sixty (60) water source heat pumps supplied the condominiums, library, lounge, and fitness center. Energy recovery ventilators were used to provide conditioned ventilation air throughout the building. The enclosed parking garage was equipped with roof exhaust fans that were interlocked with a carbon monoxide detection system. A snowmelt system was also installed to serve the entrance and exit areas of the parking garage.

American Seating Park

This project reincarnated three former American Seating Company Buildings into new residential and commercial/retail development. The projects included approximately 230,000 square feet of residential space and over 100,000 square feet of commercial/retail space. We met the heating and cooling demands with the installation of over 200 water source heat pumps. A pair of 900gpm base mounted pumps simultaneously provide circulation for the closed loop. Two boilers provide a total of four stages of loop reheat. Loop cooling demands are met by an open loop cooling tower. Circulation through the plate and frame heat exchanger is provided by two more 900gpm base mounted pumps that are staged. The single cooling tower fan is speed controlled using a variable frequency drive. A 15-ton Liebert system provides the controlled environment in the computer/server room for the commercial tenants. The Executive Office Wing is served by two Trane roof top units with spiral ductwork and zoned VVT temperature controls.

Union Square Apartments

A former Grand Rapids high school building, known to many as Union High School, was converted into 206 luxury apartments. Each unit contains a water source heat pump to provide heating, air conditioning and ventilation, as part of the closed loop WSHP system. The open loop cooling tower with plate and frame heat exchanger reject the building’s excess heat. Two boilers provide common area heat. Ten Energy Recovery Units (ERV’s) provide required ventilation air. All aspects of this project included ductwork, registers, piping and controls.

Berkey Gay Building (Apartments)

A previous furniture factory that was originally built in the 1800’s, has now become home to over 250 apartments, office space and a restaurant. This project required five (5) Energy Recovery Units (ERV’s), controls for loop boilers, cooling tower and plate heat exchanger, venting, over four-hundred (400) heat pumps, exhaust for the waste room, make up air system for the laundry room, various electric heaters, underground ductwork and thousands of feet of spiral ductwork.

Boatwerks Restaurant

A custom designed Geothermal system utilizing beautiful Lake Macatawa to house five (5) 12-ton lake pod heat exchangers, provides this restaurant with an extremely efficient and effective way to heat and cool their facility. Along with this we provided three (3) custom rooftop heat pumps, four (4) geothermal water to air heat pumps, and two (2) water to water heat pumps serving the in-floor heat, snow melt, and domestic hot water systems.

Gezon Medical

This state of the art facility required one fluid cooler, boiler, water source heat pump loop piping, Energy Recovery Unit (ERV), snowmelt system and gas piping.

Catholic Central Field House

This LEED certified project provided two (2) 30,000cfm Applied Air make up air units with 60” round Ductsox for air distribution in the gymnasium, one (1) Reznor 225mbh indirect fired make up air unit, one (1) 2-ton rooftop unit, two (2) 20,000cfm sidewall exhaust fans with 72” round louvers, two (2) 10,000cfm sidewall exhaust fans with 72” round louvers and building management controls.
