Application of CC® at a Corporate Headquarters Facility in Dallas, TX
Abstract
A corporate headquarters complex located in Dallas, TX consists of four buildings served by a central utility plant. The Continuous Commissioning® (CC®) process was applied to one building with approximately 688,000 square feet of primarily of data floor space. This building was identified as a candidate for the CC process because it consumed 58% of the 132 million kWh of electricity used by the complex in
2010 and had recently received several HVAC upgrades. CC is an ongoing process for existing buildings and central plant facilities to resolve operating problems, improve comfort, optimize energy use, and identify retrofits based on current building usage rather than original design intent [1].
The data floor optimization process consisted of three components: traditional commissioning activities, CC measure implementation, and low cost retrofits. Various M&V strategies were also utilized to quantify the resulting energy savings in a building whose energy use is dominated by data equipment load.
Using six months of pre- and post- implementation HVAC equipment electrical service meter trend data, a savings of 948,700 kWh was achieved. When these savings are extrapolated to twelve months, this project is expected to reduce the 2010 HVAC electricity usage by 25% ($133,000). Once the central plant savings are included, the overall savings of this project is approximately $146,000/year.
