- Common room
Replacing fluorescent lights with LED's, installing motion sensing light switches and adding supplementary solar panels delivers solid energy and pollution reduction benefits in a low-rise over 55's building.
The following is extracted from a case study for Willoughby City Council’s ClimateClever Apartments program.
About The Mews
The Mews consists of two two-storey buildings with a single level basement car park. The buildings were constructed in 2005 and house 21 apartments.
The Mews is an over 55s complex, and residents are mainly owner/occupiers. The complex benefits from a ‘common room’ which is well utilised and central to the community feel of the complex.
Facilities that contribute to common area energy and water consumption (and therefore the operating costs incurred by the owners corporation) include:
- Interior lighting
- Basement car park lighting
- Exterior lighting
- Lift motors
- Basement car park exhaust fan (currently not used)
- Water features
- Stormwater pumps
ClimateClever Assessment Service Results
The Mews received a free common area energy and water assessment as part of the ClimateClever Apartments Program. The ClimateClever common area energy and water assessment found:
- The electricity consumption within the common areas was 25,681 kWh per year
- The carbon footprint associated with the electricity consumption was 27.48 tonnes of greenhouse gas per year, equivalent to 549,574 balloons of carbon pollution
The recommendations of the assessment were as follows:
- Replace 50W halogen lamps running around the clock with 3W LEDs
- Install motion sensors on existing non-emergency lights
- Remove fluorescent tubes located in the basement metre room from the electrical circuit controlled by daylight sensor (PE cell) and placed on their own manual switch
- Replace 45W emergency light fluorescent tubes running around the clock in fire stairs with 15W LED tubes
- Install a solar power system
The payback period for these energy efficient measures is less than two years. This means the upfront cost of the improvements will be paid back quickly, so the owners corporation can enjoy ongoing savings.
Based on the results of the ClimateClever common area energy and water assessment, the owners corporation decided to:
- Replace 50W halogen lamps running around the clock outside the entrance foyer of the western building with 3W LEDs
- Install motion detectors in the car park (five sensors) and all internal corridors (nine sensors) that switch lights on as required
- Install LED lights in stairwell to provide safety lighting
- Install a 4.68 kW solar power system
The owners corporation applied to Willoughby City Council’s ClimateClever Apartments Grant Scheme and were awarded co-funding to implement the above actions.
