- Demand controlled ventilation
- Dedicated outdoor air systems—conditioning outdoor makeup air separately from indoor return air.
- Displacement ventilation—uses a low velocity stream of fresh, cold air at floor level to displace stale air near the ceiling
- Electronically commutated motors—variable-speed HVACR Blower
- Energy recovery ventilation (ERV)—captures energy from exhausted air and uses it to precondition incoming makeup air.
- Zero-degree heat pumps
- Duct sealing
- Adaptive logic control—adapting to HVACR systems with a wide range of operating states.
- Desiccant dehumidification—absorbs moisture with a liquid desiccant solution and then evaporates it using heat.
- Micro channel heat exchangers
- Micro environments—create a virtual zone for occupant environmental control.
- Thermal energy storage—provides cooling capacity by extracting heat from storage material, such as ice or chilled water.
- Chilled beam cooling—uses natural convection and radiative heat transfer.
- Adjustable speed drives (ASD) reducing motor speed to accommodate varying HVACR loads.
- Variable flow volume (VFV) systems—are ductless systems with multiple compressors to provide part-load performance and zoned temperature control.
