The Royal Institute for Deaf and Blind Children is an educational institution in NSW with 20,000m2 of built-up area across 14 buildings. Seeking to reduce their energy costs and carbon footprint, they sought assistance from Energy Conservation to improve their energy efficiency.

Following systematic sub-metering, data-analysis and site inspections, Energy Conservation devised a strategy to implement cost-effective efficiency measures. We built business cases for each unique measure, and with client approval we delivered procurement support and turnkey project management to implement the following:

• Rebuild of power factor correction unit

• Optimisation of head pressure control in chiller plant

• Adiabatic pre-cooling for air-cooled chiller

• Optimisation of HVAC cycles & operating schedules

• Digital time-clocks for electric hot water systems

• Replacement of timers for A/C supply fans

• Installation of evacuated tube solar hot water systems to replace deteriorated electric systems

From September 2014 onwards, the Institute has recorded significant reductions in energy consumption and carbon emissions as a direct result of these measures, with no reduction in level of service.
