ENERGY STAR Labeled Building Profile

410 Building
410 17th Street
Denver, CO 80202
Map It!

This Class A office tower is owned and operated by Equity Office Properties Trust. Constructed in 1978, the building includes 389,000 square feet of rentable space on 24 floors. An adjacent parking structure provides 343 parking spaces in seven levels.

The 410 Building has maintained a low energy usage level despite the low-tech design of the mechanical systems. The building is served by two Carrier 19EA chillers rated at 0.76 full load kW/Ton. Air distribution is accomplished by one central air system, served by four vane-axial fans. The terminal boxes are moduline variable air volume (VAV). District steam provides heat by means of a perimeter baseboard heating system, split into one zone for each exposure. Until May of 1999, all of this equipment was controlled using pneumatics, a screwdriver, and an experienced crew.

Two energy conservation projects have been completed at the 410 Building. A lighting retrofit was completed in 1996, and the new building automation system (BAS) was commissioned in June 1999. Significant savings are anticipated with the BAS in 2000, particularly in the control of the chiller plant, and the perimeter hydronic heating system. Frank Whitney, the Chief Engineer at the 410 Building, and his team of building engineers are using the BAS as a tool to operate the building in ways that were not possible with the manual and pneumatic controls. Excellent preventive maintenance and common sense operating procedures have been responsible for the 410 Building earning the ENERGY STAR for superior energy performance. The new BAS will help Frank exceed the historical performance and continue to reduce the operating costs for our tenants. The challenge in the coming years will be to maintain the energy efficiency with the increase in occupancy.
