Replacing existing exhaust fan with self-sealing exhaust fan (Schedule 15C) This weather sealing measure covers the installation of a ceiling or wall exhaust fan that has an integral self-closing damper that substantially restricts air flow through the exhaust fan when the fan is not operating. It is proposed that the products be capable of lasting for at least ten years of normal use and that they must expel air either to the outside or into the roof space of the premises. Certificates for activity = Abatement Factor x Regional Factor Current certificate allocation Air sealing measure Unit Abatement factor Replacing existing exhaust fan with Per exhaust fan 0.911 self-sealing exhaust fan (15C) Location Regional factor Melbourne / Mild 1.03 Regional Victoria / Mild 0.91 Regional Victoria / Cold 1.30 Regional Victoria / Hot 0.84 Proposed certificate allocation Air sealing measure Unit Abatement factor Replacing existing exhaust fan with Per exhaust fan 0.928 self-sealing exhaust fan (15C) Location Regional factor Melbourne / Mild 1.05 Regional Victoria / Mild 0.84 Regional Victoria / Cold 1.32 Regional Victoria / Hot 0.69 How would the number of certificates for this activity be affected? The proposed changes would create a slight alteration to the number of certificates awarded per installation. The rationale for this is explained on page 4. The changes are mainly due to updating of the mix of heating and cooling appliances, and revision of the greenhouse gas coefficients. Example: Installation of 15C in Regional/Hot location Regional Abatement Number Certificates Rounded factor factor installed Current = 0.84 x 0.911 x 1 = 0.77 1 VEEC = 0.69 x 0.928 x 1 = 0.64 1 VEEC Proposed What equipment specification changes are proposed? It is proposed that the ESC be given the power to assess and approve which products can be used for weather sealing measures and that the product specification change to require that products used be capable of lasting for at least ten years of normal use. Installing a cover with self-closing damper on existing exhaust fan (Schedule 15D) This weather sealing measure rewards the installation of a cover with self-closing damper on an existing exhaust fan. The main change proposed is that products be installed according to the manufacturer’s instructions and be capable of lasting for at least ten years of normal use.
