HVAC shootout
“1425 Mariposa St. is a four-story, 130-unit, design-build multi-family building constructed about seven years ago,” explained Brad Letourneau, at McCoy Sales, a manufacturer’s representative firm. “What makes it unique, and provides outstanding HVAC energy performance, is its IPS (Integrated Piping System) heating and cooling system. Mariposa III, as this specific building is called, was the seventh IPS project that McCoy has been involved with in Denver, and the results have been fantastic.”
When Denver Housing Authority (DHA) began the five-phase development project (Mariposa 2, 3, 4, 6 and 7), it was decided that the nearly-identical facilities would act as a shootout between five HVAC system types to determine which performs best in nearly-identical facilities.
Mariposa II features a conventional PTAC system, or packaged terminal air conditioner. Heating and cooling for Mariposa IV is supplied by VRF (Variable Refrigerant Flow) systems, while Mariposa VII utilizes a GSHP (Ground Source Heat Pump) system. Mariposa III - and later Mariposa VI - features the IPS system produced by Williams Comfort Products. The fifth building is a Combined gas heat and DX cooling.
