<strong>of</strong> approximately 2.5% was achieved over the 2004<br />

reporting period in comparison to the previous year.<br />

The Ryde Curriculum Directorate achieved outst<strong>and</strong>ing<br />

performance in the reduction <strong>of</strong> energy consumption<br />

through an awareness campaign, upgrading <strong>of</strong> air<br />

cooling systems <strong>and</strong> the installation <strong>of</strong> lighting <strong>and</strong> air<br />

cooling controls. The Facility received a 5 Star Australian<br />

Greenhouse rating by DEUS <strong>and</strong> was rated as one <strong>of</strong><br />

the five highest performing administration facilities in the<br />

<strong>NSW</strong> Government portfolio.<br />

Schools<br />

• Schools account for over 60% <strong>of</strong> the <strong>Department</strong>’s<br />

energy consumption<br />

• Average annual energy consumption per student was<br />

1670MJ<br />

• Average annual energy consumption per square<br />

metre floor area was 160 MJ<br />

• Total average consumption was slightly lower than the<br />

previous year.<br />

TAFE <strong>NSW</strong><br />

• TAFE <strong>NSW</strong> facilities account for almost 28% <strong>of</strong> the<br />

<strong>Department</strong>’s energy consumption<br />

• Average annual energy consumption per effective fulltime<br />

student was 4,032 MJ<br />

• Average annual energy consumption per square<br />

metre floor area was 365 MJ<br />

• Total average consumption was slightly lower than the<br />

previous year.<br />

The <strong>Department</strong> continues to meet the challenges <strong>of</strong><br />

achieving overall energy efficiency, while providing high<br />

quality learning environments which increasingly involve<br />

Table 17.1 Projects to improve efficiency<br />

high energy consumption from more computers in use,<br />

associated ICT equipment <strong>and</strong> air conditioning.<br />

Adopting best practice in the procurement<br />

<strong>of</strong> new assets<br />

Design <strong>and</strong> construction <strong>of</strong> new <strong>and</strong> refurbished<br />

education facilities continues to incorporate wellestablished<br />

ecologically sustainable design features in<br />

energy efficiency, water conservation <strong>and</strong> environmental<br />

considerations. Provision <strong>of</strong> low environmental impact<br />

facilities that ensure acceptable comfort condition<br />

levels are achieved through good design <strong>and</strong> passive<br />

ventilation. <strong>Education</strong> facility design features include:<br />

• Maximising the use <strong>of</strong> natural light in all new primary<br />

schools, <strong>and</strong> increasingly in high schools through the<br />

installation <strong>of</strong> ro<strong>of</strong> light strips<br />

• Integrating wind driven ro<strong>of</strong> ventilators to evacuate<br />

heat from ceiling spaces<br />

• Period bell light switching systems to automatically<br />

control lights in rooms in line with scheduled<br />

occupancy<br />

• Using insulation to reduce energy consumption for<br />

both heating <strong>and</strong> cooling<br />

• Using low flow water outlets <strong>and</strong> dual flush cisterns for<br />

improved water efficiency.<br />

Numerous research <strong>and</strong> installation projects were carried<br />

out in <strong>2005</strong> to enable the evaluation <strong>of</strong> energy efficient<br />

products. These ongoing trials ensure application <strong>of</strong> the<br />

latest technology in operations. Design specifications are<br />

applied, where appropriate, in planning <strong>and</strong> operation <strong>of</strong><br />

education facilities.<br />

During <strong>2005</strong> numerous trials <strong>of</strong> appliances were<br />

conducted <strong>and</strong> installation projects were completed.<br />

Some <strong>of</strong> those projects are detailed in the table below:<br />

Upgrading<br />

existing light<br />

fittings<br />

Both schools had all electrical components<br />

removed from the rapid start light fittings <strong>and</strong><br />

were rewired with energy efficient components<br />

<strong>and</strong> triphosphur fluorescent tubes. The retr<strong>of</strong>it<br />

was carried out to all suitable light fittings in<br />

classrooms <strong>and</strong> administration areas.<br />

As an increase in light output was achieved, a 20%<br />

reduction in the number <strong>of</strong> fluorescent tubes was<br />

possible. The reduced electrical load will reduce<br />

annual energy consumption by an estimated<br />

148,000 kWh <strong>and</strong> provide a saving <strong>of</strong> approx.<br />

$14,000 per year.<br />

Various schools Phase 4<br />

Schools<br />

In conjunction with the <strong>Department</strong> <strong>of</strong> Energy,<br />

Utilities <strong>and</strong> Sustainability, <strong>and</strong> Integral<br />

Energy, 1.5 kWh ro<strong>of</strong> mounted photovoltaic<br />

(solar) systems were installed in 27 schools<br />

throughout <strong>NSW</strong>.<br />

All electricity generated by the system is fed directly<br />

into the schools’ main electricity supply. This<br />

‘green energy’ reduces dem<strong>and</strong> for mains supplied<br />

electricity <strong>and</strong> therefore prevents the generation<br />

<strong>and</strong> release <strong>of</strong> approximately 49 tonnes <strong>of</strong> CO 2<br />

gas<br />

emissions into the atmosphere annually.<br />

Upgrading<br />

existing light<br />

fittings<br />

All electrical components were removed from<br />

the rapid start light fittings in 32 classrooms.<br />

The fittings were upgraded with a prefabricated<br />

energy efficient kit, consisting <strong>of</strong> electronic<br />

ballast, wiring <strong>and</strong> triphosphur fluorescent<br />

tubes.<br />

While operation is presently being monitored, a<br />

reduced electrical load has been achieved as has<br />

a reduction in energy <strong>and</strong> maintenance cost. There<br />

has also been a substantial increase in light output<br />

while retaining the same number <strong>of</strong> fluorescent<br />

tubes.<br />
