ASHRAE’s new worldwide headquarters will operate at net-zero-power (NZE) performance following recent set up of a big photovoltaic (PV) system. Structures classified as NZE eat less energy during the period of per year than is created onsite through renewable power resources.
“Completing installing our PV program marks a tangible milestone for ASHRAE which will demonstrate to others how exactly to successfully shift on the road to NZE position,” stated 2021-22 ASHRAE President Mick Schwedler, P.E., Fellow ASHRAE, LEED AP. “This task is specific because it’s a testament to ASHRAE’s leadership and dedication to sustainability and showcases revolutionary built environment technology. We have been proud of this essential accomplishment extremely.”
In January 2020, ASHRAE started a $20 million renovation task on its new worldwide headquarters building, situated in the favorite tech-based corridor at 180 Technologies Parkway, Peachtree Corners, GA. Built-in 1978, the prevailing 66,770-square-foot developing on 11 acres of property became a demonstration task designed to prove the financial viability of a NZE procedure.
“A significant part of addressing NZE may be the low energy usage of the building (reduced EUI of 21 kBTU/sf/yr) – while maintaining superb ventilation and IAQ,” mentioned Ginger Scoggins, P.E. Fellow ASHRAE, CEM, CxA, ASHRAE treasurer and previous chair of the ASHRAE Headquarters Constructing RANDOM Committee. “Installing the PV panel program is a superb of illustration of how exactly to reduce grid-energy intake and greenhouse emissions within an older, existing building to produce a innovative and sustainable atmosphere.”
Finished through Innovative Solar United states , the 332kW task was a variety of three sub-arrays:
- 187kW ballasted rooftop
- 65kW ground install on a southern facing hill next to the creating (enabling narrower spacing between rows and therefore higher power density)
- 81kW ground mount located in an unused portion of the parking great deal
“The purpose of the task was to go after a style that minimized environmentally friendly footprint on the website, while attempting to optimize the usage of the building’s roofing and adjacent locations that didn’t involve property disturbance or elimination of established trees,” stated Chris McMahan, commercial task manager.
The full total system size needed to be constrained within the utmost cap established by the neighborhood electric utility service provider for customers desperate to interconnect through the month-to-month netting program.
PV techniques like the ASHRAE’s offer around 25 years of functionality. The addition of strength optimizers, which are little devices that sit down behind the panels and so are paired to the SolarEdge inverters, mitigate the result of partial shading, enhance safety, and invite ASHRAE to monitor overall performance down to each person solar panel.
“Considering the total system price and the little maintenance connected with it, the levelized price of energy eventually ends up getting around four times less than the retail price from the utility,” mentioned Cesar Prieto, business growth director, Creative Solar United states. “This kind of investment isn’t only good for the surroundings, but the permanent decrease in the electricity bill is great for underneath line also.”
