Part I - General
A. Product Specification
1. Energy Recovery Ventilator (ERV) shall be a packaged unit as manufactured by RenewAire and shall transfer
both sensible and latent energy using static plate core technology.
B. Quality Assurance
1. The energy recovery ventilator shall be Certified by the Home Ventilating Institute (HVI) under CSA 439*. Both
a heating and a cooling test must be run to demonstrate year round energy recovery.
2. Manufacturer shall be able to provide evidence of independent testing of the core by Underwriters Laboratory
(UL), verifying a maximum flame spread index (FSI) of 25 and a maximum smoke developed index (SDI) of 50
thereby meeting NFPA 90A and NFPA 90B requirements for materials in a compartment handling air intended
for circulation through a duct system. The method of test shall be UL Standard 723.
3. Unit shall be Listed under UL 1812 Standard for Ducted Air to Air Heat Exchangers. The unit must pass
commercial flammability requirements and shall not be labeled “For Residential Use Only”.
4. The ERV core shall be warranted to be free of manufacturing defects and to retain its functional characteristics,
under circumstances of normal use, for a period of ten years from the date of purchase. The balance-of-unit
shall be warranted to be free of manufacturing defects and to retain its functional characteristics, under
circumstances of normal use, for a period of five years from the date of purchase.
Part II – Performance
A. Energy Transfer
The ERV shall be capable of transferring both sensible and latent energy between airstreams. Latent energy
transfer shall be accomplished by direct water vapor transfer from one airstream to the other, without exposing
transfer media in succeeding cycles directly to the exhaust air and then to the fresh air.
B. Passive Frost Control
The ERV core shall perform without condensing or frosting under normal operating conditions (defined as outside
temperatures above -10°F and inside relative humidity below 40%). Occasional more extreme conditions shall not
affect the usual function, performance or durability of the core. No condensate drains will be allowed.
C. Continuous Ventilation
Unit shall have the capacity to operate continuously without the need for bypass, recirculation, pre-heaters, or
defrost cycles under normal operating conditions.
D. Positive Airstream Separation
Water vapor transfer shall be through molecular transport by hydroscopic resin and shall not be accomplished by
“porous plate” mechanisms. Exhaust and fresh airstreams shall travel at all times in separate passages, and
airstreams shall not mix. No metal separators or metal core material shall be acceptable.
E. Laminar Flow
Airflow through the ERV core shall be laminar over the products entire operating airflow range, avoiding deposition
of particulates on the interior of the energy exchange plate material.
* BR70 not certified by HVI, independently tested and rated per CSA C439.
