Bachelor Gulch Residence

Location: Beaver Creek, CO

Project Description:

Rader Engineering was responsible for the mechanical engineering for this project, including the design of the large-scale solar thermal system. This system consists of 24 solar thermal panels as wells as 3 large volume underground concrete storage tanks for thermal storage. The tanks total more than 11,000 gallons of total volume and are super-insulated with closed cell spray foam insulation to maximize system efficiency. The system is designed to capture solar energy and use it to heat domestic hot water, space heating and exterior driveway and patio snowmelt. The estimated annual energy savings is about 192,000,000 Btu’s, which equates to a annual natural gas cost savings of around $2,800. The house also has multiple high efficiency condensing boilers and a solar PV system. The solar PV system consists of 20 panels. Both the PV and the thermal panels are flush mounted into the roof for optimal aesthetics.

Project Description:

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.
