American National Bank — Carbondale, CO

Location: Carbondale, CO

Project Description:

Energy efficiency was a primary goal for the developer of this bank. Rader Engineering met this goal by providing full Mechanical and Electrical engineering services that incorporated energy efficient systems into the MEP design. Highlights include a 10 KW solar PV system, an instantaneous gas hot water heater, Roof Top Units that used environmentally sound refrigerant, economizer cooling for free cooling utilizing outdoor air, VAV variable air volume zoning systems and an ERV energy recovery ventila tor for bath exhaust and fresh air to the offices.

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.
