EAST WENATCEE, Wash. - the architect for this design-build project strongly recommended infrared gas heaters.

Five Space-Ray LTU130 U-Tube unitized low-intensity infrared gas heaters, each with a 130,000-Btuh heating capacity, were installed by Town Toyota, of East Wenatchee, Wash., for its new 11,560-sq.-ft. service area. Shown by arrows are two of the heaters installed in one of the two six-bay areas.
East Wenatchee, Wash. - When Town Toyota decided to expand and relocate their dealership from Wenatchee to East Wenatchee, the architect for the design-build project strongly recommended infrared gas heaters over an electricity-based heating system for the new 11,560-sq.-ft. facility.

Established in 1987, the Wenatchee area's only Toyota dealership needed a larger facility to keep up with customer service and sales demands.

Terry Johnson of PKJB Architectural Group contacted Tom Rissman of Space-Ray Northwest, Space-Ray's representative for Washington and Northern Idaho. Heating requirements for the metal roof service area were determined using Space-Ray's exclusive CompuHeat¿ heat loss analysis system.

The hvac contractor was Dick's Heating and the general contractor was Hale and Long, both of East Wenatchee.

The service area consists of a six-bay, 2,775-sq.-ft. area and a six-bay, 8,790 sq. ft. detail shop, which are divided by the customer service drive. The larger area has a sloped ceiling, 20 ft. high in the center versus a 12-ft.-high ceiling in the other service area. The facility sits on a concrete slab.

The area also has three metal roll-up doors with windows, two of which are located at either side of the service drive and a third near the detail shop.

Auto dealerships

"Infrared heaters are widely used in auto dealership applications throughout North America," said Bob Genisol, vice president of sales and marketing for Space-Ray.

"In the past, we focused on the repair areas of auto dealerships. With the introduction of newer model heaters, we can now heat all parts of the dealership with infrared heat including the write-up, detailing, body shop, wash bays, parts storage, and in some cases the showroom areas."

Based on the CompuHeat¿ analysis, five Space-Ray LTU130 U-Tube unitized low-intensity infrared gas heaters were specified, each with 130,000 Btuh heating capacity.

One Space-Ray LTU130 heater was located on both ends of the service drive, one at the center of the six-bay service area, and two at either end of the 8,790-sq.-ft. service area. The heaters were installed in late 2001.

Rissman noted that Town Toyota was quick to experience the benefits of radiant heat technology in their first heating season.

"Radiant heat works from the bottom up, warming people, floors, and tools first, which results in a comfortable work environment, even during the cold winter months," Rissman said. "An effective heating system is critical for employee well-being during the September to April heating season."

According to Jeff McElroy, service manager for Town Toyota, with the Space-Ray heaters, the heat is consistent throughout the service area.

, Iowa municipal utilities building installs geothermal system

, WaterFurnace International played an integral part in a 13,000-sq.-ft. building that was included in the Top 10 Green Projects for 2002 compiled by the American Institute of Architects.

, The Iowa Association of Municipal Utilities Office and Training Headquarters in Ankeny, Iowa, was cited for its environmentally friendly design and energy efficiency.

, The AIA's Committee on the Environment selected 10 examples of architectural design solutions that protect and enhance the environment.

, "This year's winners included projects designed for the federal government, large and small businesses, nonprofit organizations and individuals, proving the environmental, social and economic benefits of sustainable design for clients of any size," the AIA said.

, Opened in February 2000, the IAMU's office and training headquarters also was conceived and designed as a teaching tool. Built on what the AIA described as a "modest budget," the building's energy consumption is 45% less than with an ordinary design.

, The building uses eight 4-ton WaterFurnace geothermal heat pumps for heating and cooling. The earth loop consists of 33 vertical boreholes, each 175 ft. deep, using more than two miles of piping.

, Other energy-saving features include extensive daylighting, lighting controls, airtight construction, on-demand water heating, heat recovery, and energy-efficient site lighting.

, The building also won the Portland AIA Energy and Environmental Award in 2001 and the Iowa Governor's Environmental Excellence Award in 2002.

, "Our goal was to design a facility that would use half the energy of a typical code-compliant office building, while staying within our budget," said Patti Cale, energy services coordinator. "When we had a cost analysis done by the Iowa Energy Center, we realized we could not afford not to have geothermal energy."

, Cale said tours of the building always include the WaterFurnace geothermal heat pumps and that the system generates great interest among visitors.

, "Either they're seriously considering using a geothermal system or they've heard about it and want to know more. Geothermal clearly is a technology that's taking off," she said.
