1 2011/SCSC/WKSP2/013 Session 3 Australian Regulations and Standards for Energy Efficiency and Conservation in Buildings Submitted by: Standards Australia Green Buildings and Green Growth: Approaches to Encouraging a Positive Green Building Climate Singapore September 2011

2 Australian Regulations and Standards for Energy Efficiency and Conservation in Buildings Adam Stingemore National Sector Manager, Operations Session outline Australian energy policy context Building Code Requirements Standards for the built environment Consequences of and Managing Change Work on the Horizon 2

3 Australian energy context Energy used by Australian buildings accounts for about 20% of Australian Greenhouse Gas Emissions Australia s energy needs expected to increase by 20% in the next 10 years with peak demand forecast to increase by 30% between Improved and achievable energy efficiency in Australian buildings to save an estimated $16.7 billion AUD / energy infrastructure spend of $165 billion AUD Significant work done by the Australian States and Territories, by industry and other interested groups to progress initiatives Regulation and Standards play a significant role in underpinning a variety of policy initiatives 3 Australian energy context Signal Step Change Market readiness Adaptability A pathway to 2020 Low Energy Low Carbon Excellent performance is technically achievable Growing demand for low energy and low carbon outcomes Consumers Corporates Asset owners Government Evolution of performance and cost efficiencies could see consistent step changes Skill formation and market transformation are key Regulatory changes need to: Signal Anticipate Change Be evidence based Work through engagement consultation and consensus Measured and flexible and be capable of dealing with contingencies 4

4 Australian energy context 1980 s saw first steps towards increasing the energy efficiency of buildings Continual process of improvement Leadership role played by the GBCA in steps towards green building practices Building Code of Australia (Performance based) has been moving towards greater energy efficiency provisions over a period of years Section J of the BCA - Energy Efficiency Objective of reducing greenhouse gas emissions (J01): A building and its services to be capable of efficiently using energy (JF1) A building s services for heating to obtain energy from A low GHG intensity source On-site renewable Another process as reclaimed energy 5 Building Regulation in Australia STAGE 1 National Construction Code for Australia FURTHER STAGES 6

5 Building Regulation in Australia National Construction Code Consolidation of plumbing and building regulations Consolidation of Code requirements for construction into one document; Building Code and Plumbing Code to be separate volumes of the National Construction Code; Subject to further progression further volumes to follow; Standards will continue to be referenced in all volumes of the code. 7 Australian energy context Section J of the BCA - Energy Efficiency Objective of reducing greenhouse gas emissions (J01): A building and its services to be capable of efficiently using energy (JF1) A building s services for heating to obtain energy from A low GHG intensity source On-site renewable Another process as reclaimed energy Standards referenced by the Construction Code Step change Fundamental change Consequential changes 8

6 Australian energy context Building Code of Australia Energy Efficiency requirements Performance Requirements Must have to the degree necessary features that facilitate the efficient use of energy appropriate to The function and use of the building and services The internal environment The geographic location of the building Solar radiation being Utilised for heating Controlled for cooling Dealing of the envelop against air leakage Utilisation of air movement to assist with heating and cooling Heating obtain energy from A source with a ghg < 101g CO2-e/ An on-site renewable source; or Another process of reclaimed energy 9 Australian energy context Building Code of Australia Energy Efficiency requirements Specifications for: Annual energy consumption of services in a building (note classes) DTS Provisions for Thermal Construction Lighting Glazing Building Sealing HVAC systems Artificial lighting and Power Hot water supply Swimming pool and spa plant 10

7 Australian energy context AS Ventilation and Air Conditioning in buildings Move to efficient HVAC practices Building Code of Australia Standards in development AS Automatic Fire Sprinklers General requirements Extensive revision underway - Modelled savings on water, co2 and other emissions AS 4666 IGU s Meet expanded efficiency requirements Structures Codes Concrete, Steel, Timber AS 3500 Plumbing Code Extensive rewrite with significant proposed efficiency and sustainability advances Materials and input Standards Sustainability gains build in to process Cement Refrigerants Lighting Water heating systems 11 Energy Efficiency Standards Refrigerators AS/NZS 4474 Clothes Washers & Dryers AS/NZS 2040 & AS/NZS 2442 Airconditioners AS/NZS 3823 Television Sets AS/NZS

8 Challenges Heritage structures Compliance with the BCA necessary in many instances Performance based (Alternative solution) framework allows for a degree of flexibility in meeting requirements Assessment methodology can and does include embodied energy calculations and assessments on retained value 13 Challenges Adaptation Fundamental shift in building construction and design Retrofitting Understanding Construction Managing unintended consequences Front end On realisation From a sustainable perspective Construction basis Cost basis To improve the performance of buildings 14
