Ingersoll Rand is committed to advancing quality of life by creating comfortable and efficient environments for its customers, and it has applied the company mission to renovations of a building at its North American headquarters in North Carolina by using LED indoor lighting fixtures, which will reduce power density by more than 36%.
“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 do.”
The updates to Building D and the considerable work that went into it had efficiency in mind from the start—beginning with a full audit of the facility's energy use, including lighting and HVAC systems.
The Ingersoll Rand Building D's commercial interior space, which comprises nearly 53,000 square feet, was transformed with more energy-efficient lighting, a building automation system with energy-saving control strategies, and ENERGY STAR® equipment and appliances. Only low-emitting materials were specified and used for the renovation; they included GE's Lumination™ ET Series Recessed Troffers, which provide energy-efficient ambient lighting to common areas, offices, shared work spaces and hallways. Featured in the large conference room are Lumination™ BL Series LED Luminaires — their long, narrow bands of light are seamlessly integrated within the ceiling for a clean, contemporary look.
“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, Ingersoll Rand.
The LED lighting fixtures further enhance energy efficiency by incorporating automatic controls, and they have lessened HVAC cooling loads while helping to improve HVAC efficiency.
Results & Benefits
Before GE's LED lighting fixtures were installed, the foot-candle reading averaged 40 fc. It now is between 43 and 44 with better uniformity. Overall, the LED lighting has reduced light power density, or watts per square foot, by more than 36 percent over the ASHRAE baseline.
As LED lighting produces less heat than traditional light sources, the air conditioning load can be reduced by 0.32 watts with every watt saved in a lighting system. Providing additional energy reduction for Building D, 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.
Even water use is now more efficient, with 40 percent less of it being used through low-flow plumbing fixtures and faucets in all restrooms.
