Ingersoll Rand helped create a comfortable and efficient environments for
its customers with building renovations at its North American Headquarters in
Davidson, North Carolina. The renovations transformed Ingersoll Rand’s
Building D commercial interior space, which occupies nearly 53,000 square feet
across two levels.
The company installed more energy efficient lighting, a building automation
system (BAS) with energy-saving control strategies, and ENERGY STAR® equipment
“Ingersoll Rand is committed to making a more efficient use of
resources a widely held value that becomes a central part of how its employees
live and work every day; it is going beyond compliance, or simply
‘following the rule,’” said Gretchen Digby, director of
global education and engagement for Ingersoll Rand’s Center for Energy
Efficiency & Sustainability. “Ingersoll Rand wants to help its
employees find ways to integrate the ideals and apply them to everything we
The updates to the space and the considerable work that went into them began
with a full audit of the facility’s energy use, including lighting and
HVAC systems. For example, 49 truckloads of building waste and materials were
recycled; 80 percent of old furniture was repurposed and refurbished; and more
than half of the demolition and packing debris was diverted from landfills.
Only low-environmental impact materials and products were specified and used
for the renovation including GE’s LED lighting fixtures.
Lumination™ ET Series recessed troffers, which are among the more
efficient lights installed in the renovation, were placed in common areas,
hallways, offices, and shared work spaces. Featured in the large conference
room are the Lumination BL Series LED Luminaires, long, narrow bands of light
that are seamlessly integrated into the ceiling. The automatic controls of LED
lighting further enhances their energy efficiency. Before the LED lighting
installation, the foot-candle reading averaged 40 fc. The space now averages
between 43 and 44 fc with improved uniformity.
Overall, GE says that its LED lighting consumers more than 36 percent fewer
watts per square foot (a lower power density) compared to the ASHRAE baseline.
GE says that the AC load can be reduced by 0.32 watts with every watt saved in
a lighting system. As LED lighting produces less heat than conventional
lighting, the AC load can reportedly be reduced by 0.32 watts for every watt
saved in the building’s lighting system. According to GE, the new lighting has
lessened HVAC cooling loads and improved HVAC efficiency by an additional 3
percent. The HVAC system itself upgrades the BAS and includes controls for
temperature settings and fan pressure optimization.
“The fixtures, appliances and other materials incorporated into
this beautifully renovated facility demonstrate that products that help
customers reduce consumption of natural resources or minimize their impact on
the environment can also generate productivity by reducing the total cost of
ownership,” said E. Jefferson Hynds, director of innovation at
“Additionally, if you can make these more energy-efficient ideals
another business level, you’ll be much more successful in changing
culture and changing behavior.”
