Utilization Efficiency (AFUE) rating.
(e) Equipment efficiency requirements are
based on either the listing by ENERGY STAR®, the directory of the
Air-Conditioning, Heating, and Refrigeration Institute (AHRI), or other
third-party certified list approved by the Director.
(3) Wastewater Heat Recovery Device is a
device designed to recover thermal energy from household wastewater streams for
the purpose of returning a portion of this energy to the dwelling's domestic
hot water system. Field performance data submitted to and approved by the
department will be the basis for tax credit qualification. The following rules
also apply:
(a) The system must meet all
plumbing code requirements for vented double-wall heat exchangers;
(b) The system must not interfere with the
proper operation of the dwelling's wastewater system; and
(c) Energy recovered must be re-introduced
into the dwelling's hot water supply system.
(4) Sealed Duct Systems must meet the
following requirements:
(a) Have all work
must done by technician with a current or valid certification with Performance
Tested Comfort System (PTCS), ACCA Quality Installation or approved by the
department as equivalent.
(b) To
apply for a sealed duct system tax credit, the following information must be
submitted on the department approved application form:
(A) Certification that Bonneville Power
Association's Prescriptive Duct Sealing Specifications have been completed;
and
(B) Itemized invoice
identifying costs.
(5) Energy Recovery Ventilators (ERVs) are
devices that provide balanced fresh air ventilation for homes with the ability
to transfer energy from the outgoing air stream to the incoming air stream.
ERVs must:
(a) Be tested, rated and certified
through the Home Ventilating Institute (HVI) Division of the Air Movement and
Control Association (AMCA) International, Inc., and listed in the HVI
directory;
(b) Be capable of at
least 30 percent Latent Recovery/Moisture Transfer (LRMT) at 32 degrees F when
operating on the lowest fan speed. LRMT is the moisture recovered to the
ventilation supply air stream divided by moisture being exhausted, corrected
for cross leakage, if any. For example, LRMT = 0 would indicate that no
exhausting moisture is recovered for the incoming supply air stream. LRMT = 1
would indicate that all exhausting moisture is recovered for the incoming
supply air stream;
(c) Have a
maximum EUI of 1.10 watts/cfm at the lowest fan speed for which performance
data is published in the HVI directory; and
(d) Have a minimum Sensible Recovery
Efficiency (SRE) of:
(A) 75 percent at
32°F/0°C when operating at the lowest fan speed; and
(B) 67 percent at 32°F/0°C when
operating at the highest fan speed.
(6) Heat Recovery Ventilators (HRVs) are
devices that provide balanced fresh air ventilation for homes with the ability
to transfer energy from the outgoing air stream to the incoming air stream.
HRVs must:
(a) Be tested, rated and certified
through the Home Ventilating Institute (HVI) Division of the Air Movement and
Control Association (AMCA) International, Inc., and listed in the HVI
directory;
(b) Have a maximum EUI
of 1.10 watts/cfm at the lowest fan speed for which performance data is
published in the HVI directory; and
(c) Have a minimum Sensible Recovery
Efficiency (SRE) of:
