Touted as the 99th busiest airport in the nation, over ½ million passengers and pilots pass through the Oakland County International Airport every year. PBA provided MEP and lighting design services for the new LEED Gold certified terminal. The energy efficient systems design resulted in the airport utility costs dropping from .70 per square foot to .39 per square foot.
The plumbing system design of low flow faucets and fixtures results in less water usage and less waste discharged into the local sanitary system. Rainwater, harvested on site, is utilized to recharge the ground water supply and to water the interior planted vegetation. A solar water heater uses the heat from the sun to generate hot water for use in the building. Central heating and cooling are supplied by a ground source, closed loop geo-exchange system that consists of over 55,000 lineal feet (over 10 miles) of tubing. The geo-exchange system is comprised of 6 circuits of a horizontal slinky-type geo-exchange field buried directly in the ground. Cooling for the building is provided by two water-to-air heat pumps or from the central water-to-water heat pumps. The central heating system consists of two 20-ton water-to-water heat pumps that generate 125-degree hot water. The main lobby is heated by 5 water-to-air heat pumps. The lighting design exceeds the minimum lighting power density requirements of the ASHRAE 90.1 – 2004 Energy Code by 7 percent.
Oakland County needed to create dedicated space for its executive branch division offices. However, the existing facility’s infrastructure was in need of significant upgrades.Learn More →
