This retrofit project started out to reduce the energy consumption at this 417.463 square foot office tower located in Beverly Hills, CA.  The original design of the HVAC system utilized discharge static pressures as high as 6.0 inches W.C., and had 1,250 kW worth of electric heat installed.

The control system would cycle the electric heating rapidly, cycling the discharge supply temperature between  74°F and 125°F, causing fairly substantial swings in the room temperatures, with the VAV system alternating between heating and cooling, and 6" of static pressure built up behind the box to force air into the space.

When the retrofit project was completed, the energy consumption had been dropped by 25.06%, and tenant complaints had been reduced by AA%, while the occupancy of the facility has increased by 10.76%.

The Chief operating engineer and his staff have been trained by ROI and they continue to improve on the system energy performance, while striving to minimize tenant complaints.
