CREJ - Building Dialogue - March 2015
An energy-efficiency project at 1670 Broadway, for the Class A, LEED Gold certified high-rise office tower in the central business district, is projected to save $128,810 per year in energy costs. Managed by Cushman & Wakefield’s Corporate Occupier and Investor Services group, the 36-story, 700,000-squarefoot landmark, which was built in 1978, recently installed a new energy management system to maximize efficiency throughout the building. Since the project’s completion in 2014, the property has realized a 20 percent reduction in overall electrical use and a 25 percent reduction in overall district steam energy use. A payback term of just over 2 1/2 years will be achieved with the EMS together with SkySpark analytic software – computer-aided tools used by building operators to monitor, control and optimize energy. Moreover, the building’s performance and Portfolio Manager/Energy Star benchmarking data is uploaded by the landlord to Global Real Estate Sustainability Benchmark. “Consistently measuring and monitoring real-time building operations is critical to good energy performance,” said Denver-based Judy Purviance-Anderson, general manager of 1670 Broadway. “Our new EMS can proactively accommodate and deliver efficient services to the building while assuring system optimization.” The success of the EMS/SkySpark project was the subject of a formal case study by Xcel Energy and can be reviewed along with other projects atwww.responsiblebynature.com. The energy saving results of the project resulted in the building receiving one of the largest rebates from the utility for a like-kind project: $184,000.
