The American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) renovated a building in Peachtree Corners, Georgia, to serve as the global headquarters of the ASHRAE organization. The facility provides an outstanding working environment for approximately 145 ASHRAE employees and extensive training and meeting space for ASHRAE members and volunteers. The project goal was to demonstrate an economical renovation of an existing structure into a Net Zero Energy building.
The original 66,770 ft² building was built in 1978 and faced several challenges in Georgia’s hot and humid climate. The building’s design employed ample exterior insulation, radiant cooling and heating, and ceiling fans to reach the thermal comfort goals to improve airflow. A dedicated outdoor air system was utilized to manage the dehumidification of the interior. The project was designed to achieve Net Zero Energy certification with a total renovation budget of $10 million without including photovoltaic arrays. The 332kW photovoltaic array is mounted on the rooftop, the lawn, and in an unused section of their parking lot. The array installation was completed in November 2021, allowing for full Net Zero Energy operation.
The ASHRAE project was also featured in Paul Hawken’s newest book Regeneration: Ending the Climate Crisis in One Generation as an example of a Zero Energy renovation completed economically.
