ASHRAE 62.1 - Ventilation for Acceptable Indoor Air Quality
ASHRAE 62.1 sets minimum ventilation rates; heat recovery helps meet them without a large energy penalty.
Read article →ASHRAE 84 - Measuring Thermal Performance of Energy Recovery
ASHRAE Standard 84 defines the North American test procedure for the thermal performance of energy recovery ventilators.

EN 16798 sets ventilation and energy requirements for non-residential buildings and links heat recovery to the EPBD.
Read article →EN 308 - Test Method for Heat Transfer in Heat Exchangers
EN 308 defines how to measure sensible and latent effectiveness of air-to-air exchangers so quoted performance is verifiable, not marketing.
Read article →Single-Stage vs Two-Stage Heat Recovery
Two-stage recovery chains exchangers for very low supply temperatures or extreme climates. Compare complexity against the gain.
Read article →Enthalpy Wheel vs Plate in Humid Climates
In humid summers, enthalpy wheels cut latent load; plates only cut sensible load. Compare for Gulf, monsoon, and sweat-climate conditions.
Read article →Aluminum vs Stainless Steel Plate Cores
Aluminum is light and highly conductive; stainless resists corrosion in aggressive airstreams. A material selection guide for plate cores.
Read article →Counterflow vs Crossflow Plate Exchanger
Counterflow plates reach higher effectiveness and colder supply temperatures; crossflow is cheaper to manufacture. Compare the two plate layouts.
Read article →Run-Around Coil vs Plate Exchanger
Run-around coils move energy between distant airstreams via a fluid loop; plates need adjacent streams. Compare siting, efficiency, and cost.
Read article →Heat-Pipe vs Plate Heat Exchanger
Heat pipes need no moving parts and self-drain frost; plates are cheaper and contamination-free. Compare the trade-offs for your duty.
