Case study prepared by Team Catalyst showing how the design of a community centre in a retirement village in western Sydney might change if the building had been designed to comply with the 2019 version of the energy efficiency provisions in Section J of Volume 1 of the National Construction Code, rather than the 2016 version. The case study focuses on the building fabric provisions. The case study was completed in early 2018 using an early draft version of Section J 2019 and does not fully reflect the final version published in February 2019.
The Boarding House project at Roselands NSW is still in design development stage, and consists of 9 sole occupancy units and a communal lounge. Out of the 9 units, 6 are proposed to be two storey structures, with a mezzanine bedroom. The 3 remaining units and communal lounge room are proposed to be single storey structures. The project is a class 3 building under the NCC, located at Roselands, inner western Sydney which falls in NCC Climate Zone 5.
The not-for-profit organisation, Arts Project Australia, provides an inner city studio and gallery to nurture and promote artists with an intellectual disability. Owning the building makes environment actions even more compelling, so when an audit helped clarify priorities, the organisation got started. It installed double-glazed and operable windows, replaced halogens with light emitting diodes (LEDs), and switched power companies. Their first bill after the changes was $1200 less than usual.
When the Alto Hotel was built in 2006, sustainability features were built into the design. Today, the hotel achieves outstanding savings in energy, waste and water use. While these features added approximately $450,000 to the $5 million build, savings on electricity, water, gas and chemicals are estimated at $50,000 per annum, and creates a point of different for customers.
At the Albion Budget Supermarket in Brunswick West Melbourne a public event helped provide funds for sustainability improvements. Called a ‘Carrotmob’, this event promises businesses a ‘mob’ of consumers in exchange for the business owner spending some of that additional revenue on sustainability improvements. The $700 raised at this event covered the cost of replacing half the supermarkets existing lights with more efficient T5 fluorescent tubes. In turn, that has saved the owners money. The supermarket is on track to save over $600 in electricity costs every year.
Newcastle French Hot Bread, a busy bakery and café in Newcastle in NSW, used an action plan to gradually implement the improvements suggested by a local energy assessor. Changes included maintenance and repair of seals on oven doors, using an off-peak timer for the electric hot water system, and separating lights to different circuits, allowing for zoning. A bill analysis also showed they’d been overcharged by their energy retailer: working via the Ombudsman recovered the business $30,000.
Major’s SUPA IGA has served its community for more than 100 years. The owners have implemented numerous energy efficiency measures including airlocking the store entrance - creating a thermal barrier, by installing a second door, reduces air exchange between external and internal areas of the store, and cuts the heating, cooling and refrigeration load. Upgrading the heating and cooling system - installing variable speed drives to the heat pump and upgrading the cooling tower to a compressed condenser with high efficiency fans to reduce energy input to energy output requirements and increas
Queensland Murray Darling Committee Inc (QMDC) completed an energy audit on commercial premises in Goondiwindi Queensland. Over the 12 months up until February 2014, the facility consumed 23,650 kWh of electricity, emitting 20.3 tonnes of carbon. An energy audit identified potential energy efficiency cost savings worth approximately $2,603 per annum with an average payback period of 1.7 years.
Queensland Murray Darling Committee Inc (QMDC) completed an energy audit on an aged care facility near Warwick, Queensland. The retirement home consists of single level accommodation buildings and the capacity to accommodate 40 residents. During the Financial Years 2012/13, the facility consumed 114,467 kWh of electricity, emitting 98 tonnes of carbon. An energy audit identified potential energy efficiency cost savings worth approximately $4,257 per annum with an average payback period of 3.1 years.
The Australian Government is delivering an additional $10.5 million in 2019–20 to improve the energy efficiency of Australian buildings.
