Rader Engineering

Rader Engineering provided mechanical engineering services for this high-end custom home in Bachelor Gulch. The highlight of the mechanical system is the GeoExchange system which consists of a large horizontal slinky pit which serves two ground source heat pumps (GSHP). Each GSHP is a 12-ton water-to-water unit that provides heating water to the radiant floors and fan coils during the winter and chilled water to the fan coils during the summer. The year round heat rejection from the AV equipment room is dumped into the ground heat exchanger where it is indirectly re-used by the heating system. Due to the GSHP system, there are no exterior air conditioning units at all for this project. Other energy efficient systems worth noting are the desuperheaters incorporated into the GSHPs which capture waste heat at the compressors and utilize this heat for domestic hot water preheating. Also, there are numerous energy recovery ventilators (ERVs) for efficient and balanced delivery of fresh outdoor air to the home.
