ASHRAE Global HQ Reaches Net
Zero Energy Milestone
ATLANTAÑAlmost two years after ASHRAE began renovating
a 1970s-era building, the Society's new global headquarters
will operate at net zero energy (NZE) performance
following the recent installation of a large photovoltaic
(PV) system.
The office is 66,770 ft2 (6,203 m2) and located on
11 acres (4.5 ha) of land at 180 Technology Parkway in
Peachtree Corners, Ga. The $20 million renovation project
was intended to prove the economic viability of an
NZE operation. Buildings classified as NZE consume less
energy over the course of a year than is generated on-site
through renewable energy resources.
The project is a testament to ASHRAE's leadership and
commitment to sustainability and showcases innovative
built environment technology, said 2021 - 22 ASHRAE
President Mick Schwedler, P.E., Fellow ASHRAE.
" Completing the installation of our PV system marks
a tangible milestone for ASHRAE that will demonstrate
to others how to successfully move on the path to NZE
status, " he said.
The PV project was a combination of three sub-arrays:
* 187 kW ballasted rooftop;
* 65 kW ground mount on a south-facing hill adjacent
to the building, allowing narrower spacing between
rows and thus higher energy density; and
* 81 kW ground mount situated in an unused section
of a parking lot.
ASHRAE renovated an offi ce built in 1978 to prove the economic
viability of a NZE operation.
The installation of the PV panel system shows how to
reduce grid-energy consumption and greenhouse emissions
in an older, existing building to create a sustainable
environment, said ASHRAE Treasurer Ginger Scoggins,
P.E., Fellow ASHRAE, former chair of the ASHRAE
Headquarters Building Ad Hoc Committee.
" An important part of getting to NZE is the low energy
consumption of the building (low EUI of 21 kBtu/ft2·yr)-
while maintaining excellent ventilation and IAQ, " she
said.
The building's NZE accomplishment was announced
just weeks before ASHRAE hosted a grand opening and
ribbon cutting ceremony in mid-November.
ASHRAE HQ: Driving HVAC Design, Technology Forward
ASHRAE's new global headquarters proves it is possible
to transform a 1970s-era building into a net zero
energy, low carbon operating offi ce-on a budget.
On the latest episode of ASHRAE Journal Podcast, the
architect, mechanical engineer of record and project
manager of ASHRAE's new HQ discuss what went into
deciding which systems to use and how the building
would operate.
ASHRAE Treasurer Ginger Scoggins, P.E., Fellow
ASHRAE, former chair of ASHRAE's Building Ad
Hoc Committee, Gregory
Walker of Houser Walker
Architecture and Stanton
Stafford of Integral Group
also share lessons learned
from this high-profi le
project.
