Rooftop variable-air-volume (VAV) systems are used to
provide comfort in a wide range of building types and climates. This
ENL discusses HVAC system design and operating strategies that can
save energy in these systems. Topics include: high efficiency
equipment, air-to-air energy recovery, relief fan vs. return fan,
evaporative condensing, hot gas bypass, hot gas reheat, maintenance
program, fan-powered VAV, single-zone VAV, airside economizer,
fan-pressure optimization, optimum start, optimum stop,
supply-air-temperature reset, ventilation optimization
(demand-controlled ventilation, ventilation reset), TRACE 700.
