: Example – change in the algorithm for 1B activities Current Regulations algorithm - Schedule 1B Proposed algorithm - Part 1B of Specifications Changes in VEEC creation for water heating activities Table 6 shows example water heating activities and the difference between the current VEEC creation and proposed VEEC creation following the proposed changes. Please note that these examples are indicative only and VEEC creation is subject to a range of influences like system size, regional factors and product efficiency. Table : Examples – changes in VEEC creation Current Schedule Proposed Scenario Activity Current VEECs Proposed VEECs 1A 1A Installation of a gas storage water heater with a storage capacity of 120 litres in Metropolitan Victoria 32 27 1B 1B Installation of an instantaneous water heater with a heating capacity of 17 L/min and a 5 star rating in Regional Victoria 21 16 1E 1D Installation of a medium heat pump water heater with a Bs of 6.113 GJ/year and a Be of 0.056 GJ/year in Regional Victoria 44 29 1F 1F Installation of a small gas/LPG boosted solar water heater with a Bs of 4.1 and Be of 0.3175 in Regional Victoria 38 30 3B 3B Installation of a large (medium under the revised Regulations) gas/LPG boosted solar water heater with a Bs of 5.1 and Be of 0.5291 in Metropolitan Melbourne 12 8 heating and cooling: Parts 5 to 10, 20 and 23 The program currently incentivises space heating and cooling upgrades, which are divided into eight space heating and cooling activities (Schedules 5-10, 20 and 23). Not all activities require decommissioning of the baseline product. Revised space heating and cooling activities The department proposes to divide space heating and cooling activities by the type of upgrade product, with each proposed activity also including several decommissioning scenarios. Combining the activities in this way will allow greater flexibility between the baseline and upgrade scenarios. It is also proposed to change the amount of GHG reduction for activities to account for: an improvement in the performance of the Victorian housing stock revised heating loads for the Victorian housing stock other variables, including the assumed system size and usage
These changes will help reduce the administrative burden for accredited providers and the ESC, and are summarised in Table 7. : Summary of space heating and cooling activity changes Current Regulations Proposed Regulations and Specifications VEEC difference Schedule Part Scenario Decommissioning Upgrade 5 5 5A(i) Ducted gas heater High efficiency ducted gas heater Mostly decreases 6 5A(ii) Central electric resistance heater Decrease 20 5A(iii) No other central heating installed Mostly decreases n/a 6 6A None, or heating or cooling as specified by the department Heating as specified by the department n/a n/a 6 6B None, or heating or cooling as specified by the department Cooling as specified by the department n/a 7 7 7A(i) Ducted air to air heat pump High efficiency ducted air to air heat pump Increase 8 7A(ii) Central electric resistance heater Decrease n/a 7A(iii) No other central heating or cooling installed n/a 9 9 9A(i) Hardwired electric room heater Flued gas or liquefied petroleum gas room space heater Increase 9A(ii) Gas or liquefied petroleum gas room heater, or type of room heating Decrease 9A(iii) Plug in electric heater or wood fire heater, when this is used as the main form of heating a premises Increase 10 10 10A(i) Hardwired electric room heater High efficiency air to air heat pump Increase 10A(ii) Non-ducted air to air heat pump or room heater Increase 10A(iii) Plug in electric heater or wood fire heater Increase 10A(iv) Refrigerative room air conditioner and hardwired electric room heater Increase 10A(v) Refrigerative room air conditioner and gas or liquefied petroleum gas room heater Decrease 23 23 23A Refrigerative air conditioner (ducted) Ducted evaporative cooler Increase Refrigerative air conditioner (not ducted) Decrease 9 and 10 - replacing fixed electric heaters and other inefficient baseline technologies
