Welcome CVEN 4104 – Sustainability in Construction Dr Ali Kashani [email protected] Workshop 5 Workshop 5 – Green rating systems in Australia Outline ‰ A quick recap of green building ratings in Australia ‰ Practising on BASIX assessment ‰ Assessment questions from last year © Dr Ali Kashani © Dr Ali Kashani Environmental impacts for building and fitout, construction and operation assessment © Dr Ali Kashani Green star rating Building design, As Built, Interiors, Communities Building performance © Dr Ali Kashani National Australian Built Environment Rating System (NABERS) ‰ NABERS is a rating system for buildings energy efficiency, carbon emissions, water consumption and waste production ‰ NABERS uses the following tools to assess building performance compared to similar buildings in the same location – Energy (without Greenpower) – Energy (with Greenpower) – Carbon Neutral – Waste – Water – Indoor Environment © Dr Ali Kashani NABERS rating © Dr Ali Kashani NABERS rating is legally required for commercial buildings if spaces within office buildings of 1000 square metres or more Under the Building Energy Efficiency Disclosure (BEED) Act 2010 (mandatory disclosure of NABERS Energy Rating at point of sale or lease) © Dr Ali Kashani NatHERS rating ‰ NatHERS is administered by the Department of the Environment and Energy on behalf of the states and territories. ‰ NatHERS star ratings provide information about the thermal performance (heating and cooling needs) of a house construction. ‰ Star ratings are based on information about the house design, construction materials and the climate where it is being built. ‰ Required for mandatory energy efficiency requirements for homes and major renovations based on the National Construction Code © Dr Ali Kashani What the stars mean? Homes with a higher star rating are considered more thermally comfortable and cheaper to run than homes with a lower star rating. ‰ a 0-star rating means the building shell does practically nothing to reduce the discomfort of hot or cold weather. ‰ a 6-star rating is the minimum standard in most states and territories. It indicates good, but not outstanding, thermal performance. ‰ a 10-star rated home may not need any artificial cooling or heating to keep you comfortable. © Dr Ali Kashani Building Sustainability Index (BASIX) in NSW ‰ BASIX aims to deliver equitable, effective water and greenhouse gas reductions across NSW. ‰ BASIX assesses thermal performance, water consumption and greenhouse gas emissions by using data provided regarding the building development design. ‰ BASIX calculates how your single dwelling, alteration and addition or multi- unit is likely to perform against a benchmark development of the same type. ‰ New residential buildings classified by the NCC as class 1, class 2 and parts of class 4 buildings and undertaking renovations of >$50,000 are subject to BASIX. © Dr Ali Kashani Create a BASIX account (Education) • https://www.planningportal .nsw.gov.au/basix © Dr Ali Kashani © Dr Ali Kashani © Dr Ali Kashani http://www.nswlrs.com.au/plan_and_title_registration/plan_types Plan types in NSW © Dr Ali Kashani © Dr Ali Kashani Next Steps: Details of planned water usage, thermal comfort and energy towards BASIX certificate © Dr Ali Kashani Break time © Dr Ali Kashani Questions from last year’s assessment (Lecture 6) A construction firm has been given a contract to build a library in NSW with the theme of sustainability, which third-party rating system is the most suitable to approve its design and fitouts? a.
