Over 45,000m2 of Gross Lettable Area, annual foot-count over 7.5 million
people.
Top management drives an integrated stainability: energy, water and
waste through technological, operational and behavioural changes.
EE includes:
– Upgrading to LED lighting and a more efficient chiller plant
– New, integrated building management system (BMS)
– Improvements in HVAC system.
500kWp pilot rooftop solar PV. 2108 panels covering 3300m2. Supplies 5% of
their electricity needs. Annual avg daily energy produced is 2,100 kWh =
avg daily use of 105 middle income homes. Carbon emission reductions of
767 tonnes. Insulation reduces cooling for floorspace below by 50-68% in
summer months.
Consistent savings averaging at 11% so far, with the hot summer months still
to come where savings reach about 17%.
Payback 8 – 11 years.
Ongoing behavioural and awareness for staff, tenants and clientele.
A waste-to-energy plant has been constructed, which will introduce a
further 250-330 kWh per day in the near future.

485 students at two campuses.
Inclusive approach, with impacts not achieved by new technologies
alone.
EE and RE over past 3 years, with help from Energy Intelligence:
Fluorescent lights to LED technology
Heat pump for hot water.
10 kWp solar PV provides about 20% of usage, and sell excess power back
to the grid over weekends to generate valuable income for the school.
So far saving 15% and the payback is about 5 years.
Now planning grid-tied solar PV for the second campus too.
Energy awareness amongst staff and learners has led to lowered use of
HVAC & lighting. Learners have constructed a wind turbine to run the
pump for drip irrigation of vertical food garden.
Led by example as a place of education. Involving children in energy
efficiency today will have a multiplied effect in years to come. Parents and
board members now also considering more sustainable energy.
