1670 Broadway, inside and out.

n 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-square-

foot 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 mon-

itor, control and optimize energy. Moreover, the building’s

performance and Portfolio Manager/Energy Star bench-

marking 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 perfor-

mance,” said Denver-based Judy Purviance-Anderson, gen-

eral manager of 1670 Broadway. “Our new EMS can proac-

tively 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 at

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.
