HVAC

(Heating / Ventilation / Air Conditioning)

  • Tune up the HVAC control system.
  • Consider installing a building automation system (BAS) or energy management system (EMS) or restoring an out-of-service one.
  • Balance the system to minimize flows and reduce blower/fan/pump power requirements.
  • Eliminate or reduce reheat whenever possible.
  • Use appropriate HVAC thermostat setback.
  • Use morning pre-cooling in summer and pre-heating in winter (i.e. ~ before electrical peak hours).
  • Use building thermal lag to minimize HVAC equipment operating time.
  • In winter during unoccupied periods, allow temperatures to fall as low as possible without freezing water lines or damaging stored materials.
  • In summer during unoccupied periods, allow temperatures to rise as high as possible without damaging stored materials.
  • Improve control and utilization of outside air.
  • Use air-to-air heat exchangers to reduce energy requirements for heating and cooling of outside air.
  • Reduce HVAC system operating hours (e.g. ~ night, weekend).
  • Optimize ventilation.
  • Ventilate only when necessary. To allow some areas to be shut down when unoccupied,  install  dedicated HVAC  systems  on continuous  loads  (e.g.   ~ computer rooms).
  • Provide dedicated outside air supply to kitchens, cleaning rooms, combustion equipment, etc. to avoid excessive exhausting of conditioned air.
  • Use evaporative cooling in dry climates.
  • Reduce humidification or dehumidification during unoccupied periods.
  • Use atomization rather than steam for humidification where possible.
  • Clean HVAC unit coils periodically and comb mashed fins.
  • Upgrade  filter banks  to reduce pressure  drop  and thus  lower fan power requirements.
  • Check HVAC filters on a schedule (at least monthly) and clean/change if appropriate.
  • Check pneumatic controls air compressors for proper operation, cycling, and maintenance.
  • Isolate air conditioned loading dock areas and cool storage areas using high-speed doors or clear PVC strip curtains.
  • Install ceiling fans to minimize thermal stratification in high-bay areas.
  • Relocate air diffusers to optimum heights in areas with high ceilings.
  • Consider reducing ceiling heights.
  • Eliminate obstructions in front of radiators, baseboard heaters, etc.
  • Check reflectors on infrared heaters for cleanliness and proper beam direction.
  • Use professionally-designed industrial ventilation hoods for dust and vapor control.
  • Use local infrared heat for personnel rather than heating the entire area.
  • Use spot cooling and heating (e.g. ~ use ceiling fans for personnel rather than cooling the entire area).
  • Purchase only high-efficiency models for HVAC window units.
  • Put HVAC window units on timer control.
  • Don't oversize cooling units. (Oversized units will "short cycle" which results in poor humidity control.)
  • Install multi-fueling capability and run with the cheapest fuel available at the time.
  • Consider dedicated make-up air for exhaust hoods.
  • Minimize HVAC fan speeds.
  • Consider desiccant drying of outside air to reduce cooling requirements in humid climates.
  • Consider ground source heat pumps.
  • Seal leaky HVAC ductwork.
  • Seal all leaks around coils.
  • Repair loose or damaged flexible connections (including those under air handling units).
  • Eliminate simultaneous heating and cooling during seasonal transition periods.
  • Zone HVAC air and water systems to minimize energy use.
  • Inspect, clean, lubricate, and adjust damper blades and linkages.
  • Establish an HVAC efficiency-maintenance program. Start with an energy audit and follow-up, then make an HVAC efficiency-maintenance program a part of your continuous energy management program.
