About Dennington
The facilities that contribute to common area energy and water consumption (and therefore the operating costs incurred by the owners corporation) include:
- Lighting in corridors, fire stairs, car parks, function room, garbage bin room and outdoor areas
- Lift in the mid rise tower
- Swimming Pool and associated changing room with toilet and shower
- Stormwater pump
- Gardens and flower beds
- Various electrical cupboards and plant rooms
ClimateClever Assessment Service Results
The electricity consumption within the common areas was 77,381 kWh per year.
- The carbon footprint associated with electricity consumption was 82.8 tonnes of greenhouse gas per year, equivalent to 1,655,949 balloons of carbon pollution
- Water consumption within the common areas was 11,495 kL of water, the equivalent of 4.6 standard Olympic sized swimming pools
The recommendations were:
- Replacement of 45 x 36W fluorescent tubes running 24/7 in car parks with 15W LED tube
- Installation of motion sensors on lights in lift operating 24/7
- Installation of a rainwater tank to provide water to garden and pool top up etc
- Installation of flow restrictors on common areas taps, showers etc
- Installation of a Solar Power system to help offset common area operating costs and reduce carbon footprint
ClimateClever Co-Funded Sustainability Performance Improvements
Based on the results of the ClimateClever Common Area Energy and Water Assessment the owners corporation decided to implement:
- The replacement of 57 x 36W fluorescent tubes in the car parks and other common areas with 15W LED tube; and
- The installation of a 6.8 kW Solar Power System
Dennington applied to Willoughby City Council for a ClimateClever Apartments grant and was awarded a grant to co-fund these actions.
They will save around $8,000 each year once the initial investment is paid off by the savings made.
