Here's just a small sampling of the businesses we've helped to grow in resource efficiency.
Warehouse Lighting Upgrade
Cumberland Country Golf Club
Cumberland Country Golf Club has had major success with assistance from Energy Conservation. With our help, they were able to obtain funding from the Environment Protection Agency (EPA) Bin Trim program for a shredder to turn ground waste into garden mulch. They now re-use around 38 tonnes of green waste every year that would otherwise go to landfill.
OFFICE BUILDING - SAVING $3K PER MONTH
A 6 storey strata plan office building with restaurant and 2 level car park which was experiencing rising energy costs. The owners commissioned Energy Conservation to conduct an energy audit of the premises. Our process included:
- Initial on-site discussions with owners committee to identify issues and priorities for investigation;
- Assessment of electricity bills, applicable tariffs and analysis of meter data;
- Full site inspection to assess energy-using plant & equipment;
- Establishment of energy end-user equipment breakdown;
- Identification of Energy Conservation Measures (ECM);
- Discussion with owners to select ECM for development of business cases and development of an actionable implementation strategy;
- Presentation of results to the owners committee.
The energy audit identified 194MWh, equating to $46,000, per annum savings; with almost $15,000 in annual savings achievable with a simple payback of 9 months. This return on investment provided a compelling platform for the owner’s committee to proceed with implementation of most of the proposed Energy Conservation Measures (ECM). We assisted the owners to implement measures including:
- Change of Network Tariff and installation of Power Factor Correction;
- 365-day digital relays for HVAC supply-fans;
- VSD for cooling tower fan;
- Time-relays for electric hot water systems; and
- Additional LED lighting
Most of the proposed ECM have now been implemented. Common service energy bills have fallen by $2500 to $3000 per month. Energy Conservation is assisting to re-design the HVAC system through whole-building modelling in simulation software.
Royal institute for deaf and blind children
An educational institute in NSW, consisting of 20,000m2 of built-up area across 14 buildings, worked with Energy Conservation to reduce its energy costs and carbon footprint through improved energy efficiency.
Following systematic sub-metering, data-analysis and site inspections, Energy Conservation devised a strategy to implement cost-effective conservation measures. We built business cases for each measure and after obtaining client approval we delivered procurement support and turnkey project management to implement conservation measures including:
- Rebuild of Power Factor Correction Unit;
- Optimisation of head pressure control in chiller plant;
- Adiabatic pre-cooling for air-cooled chiller;
- Optimisation of Heating, Ventilation & Air-Conditioning operating schedules;
- Optimisation of Outside Air and Economy Cycle;
- Digital time-clocks for Electric Storage Hot Water Systems;
- Replacement of time-clock for A/C supply-fan;
- Installation of Evacuated Tube Solar Hot Water Systems to replace deteriorated electric hot water systems.
As a result of these implementations, the Institute has recorded significant reductions in energy consumption and carbon-emissions from September 2014 onwards, with no reduction in level of service.
