At Carlton’s Café Lua, a local program helped inspire a range of sustainability improvements. These include switching to compostable take away cups, installing water-saving tap aerators, installing energy-efficient lighting and installing louvre windows for ventilation – a move which reduces the need for energy intensive air conditioning.
At Northcote’s Café Koula, changing the lighting has led to changing the atmosphere in the busy café. Compact fluorescents replaced 105 watt metal halides, giving an equivalent light while using less energy, and improving light in the café’s work areas. A produce garden is popular with families, and waste is fed to local chickens or in a retrofitted worm farm. Financially, the business has saved $140 a year electricity and maintenance costs, while reducing its greenhouse emissions.
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 New South Wales 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.
At Bendigo’s Indulge Fine Belgian Chocolates, energy efficiency improvements began with behaviour change: at night, all lights are switched and electric hot water is unplugged. Next, the owner installed light emitting diodes (LEDs), an energy-efficient refrigerator, never ran the air conditioner at less than 25°C degrees, and used excess heat from machinery to replace the store’s reverse cycle heater in winter. These combined actions mean that despite the business growing 20% in the last 4 years, its energy consumption has stayed still; a cost saving of $1600 per annum.
At Goldfields Revegetation, a specialised plant nursery in Victoria’s Mandurang, the owners had a goal of reducing the company’s energy consumption by 30%. An energy assessment proved up to 70% savings were possible, and would save the company $6000 per annum. Reductions came from: replacing 50W halogens with energy efficient 35W halogens; installing motion sensors on external flood lights; fitting a timer to the electric hot water system; installing 1.6kW solar PV system; and numerous behaviour changes.
