As a Partner in the ENERGY STAR® Small Business program and a founding member of the National Association of Physicians for the Environment, the American Academy of Otolaryngology-Head and Neck Surgery Foundation is a healthcare pioneer of pollution prevention through energy efficiency. Energy-efficiency upgrades in the Foundation’s 3-story office building have resulted in annual savings of $7,680—the pollution-prevention equivalent of planting 26 acres of trees.
38 Percent Savings From Lighting Upgrade
The Foundation’s original lighting was typical of a commercial office building. It included four 40-watt, T-12 lamps and one magnetic ballast per fixture. After learning about the energy-efficient lighting technologies available and the energy savings that came with them, Eric Dallas, the Foundation’s facility director, obtained approval to upgrade the facility’s lighting. Dallas hired a lighting contractor to retrofit 183 fixtures with two 32-watt, T-8 lamps and electronic ballasts. Specular reflectors were also added to each fixture to distribute light more efficiently. With the new lighting, offices are brighter and employees are pleased with the softer light and reduced computer glare — and the Foundation is saving $6,400 per year.
In addition, the Foundation replaced approximately 40 incandescent lamps with compact fluorescents and plans to upgrade another 20 incandescent lamps as they burn out. The Foundation upgraded 13 exit signs, which were often burning out, from incandescent lamps to light emitting diodes (LEDs) that will last more than 20 years, saving energy and labor costs.
Automation Helps Control Energy Costs
In late 1996, the Foundation installed a system that automates the heating, ventilating, and air-conditioning (HVAC) as well as lighting controls in its facility. The facility has a hybrid HVAC system, which means there are two different types of systems (central and incremental) that work together for heating, ventilating, and cooling. The central core and coil system conditions public spaces such as the foyer and hallways. The incremental system includes 83 units that individually heat and cool office spaces. Before installation of the automated control system, the incremental units and the lighting were often left on all night and on weekends. Now, the system turns HVAC units and lights off when employees are not in the building, saving both energy and money for the Foundation.
The automated control system works when the last employee on each floor to leave in the evening and the first to arrive in the morning enter a code on a wall-mounted keypad. This automatically turns the lights and heat or air-conditioning off or on. Employees can still individually control the lighting and incremental HVAC systems in their offices; the automated system simply ensures energy is being used only when needed. The system can also control computers, coffee makers, copiers, printers, and other energy-using office equipment.
Insulation Against Costs
The Foundation has also increased the efficiency of its roof. During the winter of 1996, the roof had several leaks, and after analyzing the cost of replacement versus repair, the Foundation chose the replacement option. A factor contributing to this decision was the energy savings that would be achieved by increasing the roof’s insulation from an R-value of two to an R-value of 20. The roof upgrade, completed in March 1997, is expected to lower demand for conditioned air, especially on the top floor.
In addition to practicing energy-efficiency through lighting, HVAC, and roof insulation, the Foundation maintains peak efficiency by hiring a contractor to regularly check the windows and doors for leaks. And for the past six years, employees have recycled aluminum cans, glass, paper, and cardboard to help conserve natural resources.
“We hope that the Foundation’s energy-efficiency upgrade will inspire the “greening” of physicians’ offices across America.”
