Abstract
Mechanical heating, ventilating, and air-conditioning (HVAC) systems are designed to provide thermal comfort and indoor air quality. The type of system, its efficiency, and its components and control strategies should be designed and selected to minimize energy consumption and to maximize comfort throughout the range of operating conditions. This chapter discusses mechanical equipment requirements, and important energy-efficiency aspects, including energy recovery, heat recovery in combination with indirect evaporative cooping, HVAC system air leakage requirements, duct insulation, and hot and cold water pipe insulation.
