The fab (short for fabrication) building is the largest building on the RFAB campus.

Sustainable features of the fab offer many benefits:

• Well insulated and air tight construction help maximize energy efficiency
• High efficiency fan filter units provide air recirculation and cleaning but require less energy than traditional units
• Run-around coils on the make-up air provide free reheat on the discharge side of the unit
• Use of bigger and straighter pipes and ducts reduce pressure loss, which allows smaller, more efficient fans and pumps to be used
• Gravity-driven waste streams eliminate the need for pump stations
• Premium efficiency motors help reduce energy consumption
