Engineering Tomorrow Helps DC Office Building Maximize Efficiency, Minimize System Complexity

In the competitive commercial real estate market, providing leasable office space can push building owners to consider new strategies and solutions to improve net operating income by reducing operational costs, while also offering attractive benefits for tenants. For Tim Blanch of Washington, DC-based real estate development and management firm S.C. Herman & Associates, this means placing high value on technologies that improve energy efficiency, reducing supplemental cooling costs, and improving occupant comfort.

Oil-free compressors maintain consistent performance over time

Danfoss conducted a study to see how long term operation affected performance on Danfoss Turbocor^® compressors. The results showed that oil-free, magnetic bearing compressors maintained consistent performance even after 10+ years of operation.

University’s marine science lab finds extreme savings with variable-speed chiller plant

Located close to various waterways, the University of North Carolina Wilmington (UNCW) takes marine science seriously. Its new MARBIONC Building — a 69,000-square-foot interdisciplinary research facility for marine biotechnology — provides labs for lease to commercial enterprises that require reliable, energy-efficient 24/7/365 cooling. Faced with high humidity and mid-Atlantic climate variations, the building required a chiller plant that could take advantage of a wide range of operating conditions and still run reliably.
