Constructed in 1998, the three-story, 126,000-square-foot glass and steel facility houses 225 occupants and consolidates corporate staff that was originally scattered throughout three separate locations.
“The Energy Star distinguishes the building as one of the top 25% in the nation in terms of energy performance, and makes it a testament to improving the environment as well as the company’s bottom line,” states Jean Lupinacci, Director of the Energy Star Commercial and Industrial Branch.
“Environmental management at Armstrong is embedded in our corporate culture,” notes James S. Baker, Director of Facilities Management at Armstrong.
“We are indeed proud that the Energy Star program has recognized the ongoing energy conservation measures that have become the norm in the daily operation of our headquarters building.”
EPA awards the Energy Star label to facilities that achieve energy performance ratings of 75 or better, on a scale from 1 to 100. Ratings are calculated by comparing buildings of similar square footage on factors such as location, energy consumption, number of occupants, number of computers and other equipment present, and hours of operation.
In addition, the building must conform to industry standards for thermal comfort, air ventilation, control of indoor air pollutants, and illumination.
The building uses an advanced heating, ventilating and air conditioning (HVAC) system that includes energy efficient motors for all air handlers and pumps in the building, along with an Energy Management Control System to control the motor systems and space temperatures.
The HVAC system also features variable speed drives on all fans and pumps to reduce energy usage during part load/non-occupied periods. All HVAC equipment uses CFC-free refrigeration and is zoned to create smaller areas for climate control.
Combination of Natural and Artificial Light
The building’s design allows natural light to penetrate deep into the building. Exterior sunshades ensure that summer sun does not overheat the interior and drive up cooling requirements. Integrated control systems interface with lighting systems through outdoor photocells and timer functions to reduce energy consumption.
Inside the building, occupancy sensors control lighting when spaces
are occupied. Dual level lighting further minimizes the use of artificial light and related heat gains. The uplighting applications take advantage of the Armstrong
high light reflectance ceiling panels used throughout the work spaces.
Measurement Devices Provide Feedback
The application of energy measurement devices provides continuous feedback on building performance compared to building specifications.
