Alterations & Additions policy Will operate as part of the existing website; Sets simple, specific conditions, based on the intended work; Only applies to the sections of the home that are being renovated; Relevant BASIX commitments must be shown on plans

Existing Policies: 

Existing Policies BASIX will override all energy and water efficiency policies presently applied to residential development by councils. For example: Requirements for raintanks, solar water heaters; Insulation and shading requirements; Existing Energy Smart Homes policy components.

What it means for Councils: 

What it means for Councils Ensure BASIX Certificate accompanies BASIX-affected Alterations and Additions DAs/CDCs; Check plans for appropriate marking of BASIX commitments: Rainwater tank – with size stated Pool / spa covers Pool / spa pumps and heating systems Water heater type Lighting Added insulation, glazing, shading

What it means for Councils: 

What it means for Councils Ensure BASIX commitments delivered at construction stage, evidenced by visual inspection and/or; third-party certification.

Implementation:

Pools + Spas: 

Pools + Spas Average pool size in NSW is 48,700 litres; Homes with pools have an additional 10% water consumption above the average; Increased water usage is due to evaporation, splash and backwash; Increased energy usage isdue to pool pump and heating; NSW Health supports rainwater tanks for topping up swimming pools.

Pools: 

Pools BASIX requirements are set depending on pool type and location. They may include: Filter pump timer Cover Shading Rainwater tank for top-up

Pools: 

Pools Rainwater tank size varies according to: Location / climate Pool size Roof catchment area Heating type Use of cover The tap must be within 10 metres of the pool; For large, unheated pools, installing a cover and/or shading will reduce rainwater tank size.
