ASHRAE Global Headquarters HVAC Design to Provide Comfort, Transparency, and Energy Efficiency
ASHRAE’s newly renovated global headquarters in Peachtree Corners, Ga., will showcase the latest HVAC equipment and technology offered by Belimo. The building includes design and renovation updates to achieve a net-zero energy-efficient workplace environment.
The two-story building, including a partial basement, is designed for 145 occupants with a serviceable life of at least 50 years and 20 years for HVAC components. The building occupant’s thermal comfort relies on the heating and cooling modes from 79 radiant panels controlled by 6-way ePIVs. The valves feature a single analog input to control both heating and cooling to simplify the DDC system. They also provide true flow readings, dynamic balancing regardless of pressure fluctuations in the system, and seamless integration via BACnet. The six water-sourced heat pumps with energy-saving coil isolation provided by two 2-way ePIVs control flow regardless of pressure.
The BAS uses the BACnet communication protocol complying with ASHRAE Standard 135, a Data Communication Protocol for Building Automation and Control Networks. It integrates coil flow and other performance data from the butterfly valves, ePIVs, and Energy Valves. The devices offer seamless data integration to the BAS for trending, trouble and alarm indication, and remote device network management.
The resilient seated butterfly valves are designed specifically for HVAC applications for use in ANSI pipe systems requiring zero leakage. The self-adjusting end stop algorithm ensures zero leakage at 200 psi close-off. The patented brushless DC motor technology reduces energy consumption by up to 80% and provides optimal system performance. Near Field Communication (NFC) and BACnet communication provide superior application data access for troubleshooting, commissioning, and programming.
With world-class field-level devices installed, ASHRAE headquarters will perform to its full potential.
