Owned
by TIAA and managed by Transwestern, Capital Gateway I, located
at 6700 Rockledge Drive in Bethesda, Maryland, is one of two
buildings in a 13.5-acre office development in North Bethesda.
Capital Gateway I is a 300,000 square foot, five-story building
designed by the renowned firm of Pei Cobb Freed & Partners. In
addition to the property's strikingly simple exterior, it includes a
central courtyard with a stone fountain, paper birch trees, and teak benches.
As a result of a program of retrofitting and energy conscious
building management, Capital Gateway I earned the ENERGY STAR for
superior energy performance. Lighting in common and tenant spaces is
controlled by dual-technology motion sensors, using both ultrasonic
and infrared motion sensors to help minimize unnecessary lighting
operation. This emphasis on reducing unnecessary energy consumption
extends to the property's HVAC systems as well, with variable
frequency drives (VFDs) controlling the operation of cooling tower
fans and condenser pumps, while demand limiters are used to cycle
compressors during periods of peak demand. VFDs are also used in the
domestic water pump, helping to ensure that its operation closely
aligns with actual demand. The same principle is at work in the
parking garage, where carbon monoxide sensors control the operation
of exhaust fans. Proactive building management, aided by a
sophisticated building management system, deserves a good portion of
the credit as well.
In January 2008, a high efficiency sand filter system was
installed to reduce the particle size in the condenser water system.
This, coupled with an ultraviolet (UV) light system, has reduced the
property's chemical usage, further preserving local waterways. It
has also improved water quality, which has resulted in a significant
reduction in energy consumption of the building's HVAC system.
In 2009, VFDs were installed on the outside air fans along
with rebalancing to further reduce the energy usage.
