BASIX Alterations + Additions June 2006
Alterations & Additions policy Objective: To require renovations to include practical measures that will reduce greenhouse gas emissions and potable water consumption.
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 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 • 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 • Ensure BASIX commitments delivered at construction stage, evidenced • by visual inspection and/or; • third-party certification.
Implementation Examples of projects that will require a BASIX Certificate (assuming a DA or CDC is required): • Extensions of living areas, bedrooms, bathrooms, kitchens; • New living areas, bedrooms, bathrooms, kitchens, on a dwelling site (eg. a new, freestanding enclosed pavilion); • Modifications to the building fabric of an existing dwelling; • New swimming pools and/or outdoor spas; • New hot water systems.
Implementation It is NOT the intent to require a BASIX Certificate for the following: • New garages or carports • New structures that cannot be fully enclosed, e.g. gazebos • New pergolas, verandahs or shading devices such as awnings, where they are the only development proposed • DA/CDC for only a solar hot water system
How will it work? The user enters relevant project details
How will it work? BASIX provides prescriptive requirements for Water, Energy and Thermal Comfort – there areno targets;
How will it work? Once all requirements have been met, a BASIX Certificate can be printed;
Plan Marking BASIX requirements must be marked on plans: • Insulation types/R-Values; • All wall, floor, ceiling and roof construction types; • All glazing and frame types; • Shading devices and overshadowing objects; • Raintanks – location and capacity in litres; • Rainwater/stormwater collection areas in m2; • Hot water system type and location;
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 BASIX requirements are set depending on pool type and location. They may include: • Filter pump timer • Cover • Shading • Rainwater tank for top-up
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.
Water Minimum requirements: • 3* for new basin taps (excluding bath and laundry), showerheads, and toilets; • Rainwater tank for new pool/outdoor spa in most locations; • Pool cover if pool is heated. Raintank size required is determined by: • Roof capture area; • Location; • Installation of pool heating; • Installation of a pool cover.
Energy Proposed minimum requirements: • Lights must be energy efficient (e.g. fluorescent); • Solar, heat-pump, gas storage or gas instantaneous hot water systems if being replaced; • Day/night zoning for new A/C system; • Timer on pool filter pump; • Electric resistance pool heating not permitted.
Thermal Comfort • Insulation required for new: • Suspended floors; • External walls; • Ceilings; • Roofs, if they are dark or medium colour.
First Floor Addition – North coast climate zone To pass: 3* for new basin taps and showerhead in bath Energy efficient lighting New hot water system - solar Day/night zoning for new A/C system Insulation in new external walls, ceilings and roof 750mm eaves on north 750mm eaves plus toned glass to E & W – bed 2, or external louvres with clear glass 3m roof overhang to W bed 3, therefore no toned glass
