Water initiatives in schools

Wetlands or irrigation Mulch on garden beds

Rain water tanksor toilet ushing

Low rainall and water restrictions haveaected schools and all school designs mustnow include initiatives to reduce the demandor drinking water.

All new schools now eature, Low ow taps, dual ush toilets,urinal ushing control mechanisms or waterless urinals to helpreduce water consumption.

New schools also eature water tanks or wetlands which providewater or toilet ushing and irrigation.

To urther reduce the demand or water all new schools nowincorporate indigenous plants and groundcovers with mulchedbeds to reduce evaporation. Drought tolerant plants

Alternative Energy Supplies

Solar hot water

Victoria has good access to wind and solarenergy, which means schools are great settingsor renewable energy demonstration projects.

Some Victorian schools are generating their energy needs rom wind

and many are now using solar energy to heat water. For example,Murtoa P12 College is installing an 80kW wind turbine whichwill power the entire school. Others are planning to generate theirelectricity using wind and solar power combinations.

A variety o solar and wind technologies are commercially available.

Ventilation

Ventilation is important tointernal school environmentsbecause it aects student

alertness and concentration.Ventilation dilutes odours andlimits the concentration ocarbon dioxide and airbornepollutants such as volatileorganic compounds (VOCs).Ventilation air is otendelivered by mechanicalsystems or through openwindows.

ESD Guidelines

The ESD Guidelines will establish a common methodology or incorporatingsustainability into the planning, design and construction processes or all newor upgrade school capital projects.

This will ensure new Victorian schools meet Australian best practice standards

in environmental perormance.The guidelines reer to the Green Star Education Tool developed by the GreenBuilding Council o Australia. This tool assesses the environmental impacts oa building across nine categories: indoor environment quality energy transport water materials land use and ecology emissions innovation.

Design Material Selection

Smart material selection can greatly reduce the environmental impact o a

school. Key principles to consider include the durability and low maintenancerequirements o a material. Other items to consider include:

the amount o energy required to produce the material (embodied energyCO2 emissions during manuacture)

impacts on the local environment caused by extracting material, such aswood harvested rom native orests

toxicity o materials look or paints with low Volatile Organic Compoundsand composite wood products with low ormaldehyde content

transportation o the material during manuacture and delivery to site

degree o pollution resulting rom the material at the end o its useul lie

preerence or materials which can be recycled.

Construction Resource Recovery

The amount o building materials used in a capital works project aects itsenvironmental impacts and increases construction costs. Speciying standard-sized building materials helps reduce cost and waste o a construction orupgrade project. The construction company is also responsible or recyclingconstruction and demolition waste and should prepare a Construction WasteMinimisation Plan and a Demolition Waste Minimisation Plan.

Operation Waste Recycling

Recycling stations are now a standard eature o sustainable schools. Adedicated storage area should be provided or collecting and recycling schoolconsumables with good access or all building occupants and or collection byrecycling companies. The storage area should allow or recycling o at leastpaper, glass, plastics, metals and organic (compost) materials.

Insulation

Eaves Shading High perormance glazing

NSULATION Insulation is the single most eective item you can add to your school to improve its energy efciency. As it helps maintain internal temperatures andreduces the need or heating or cooling. Walls Heat loss and Heat gain = 10 15% Roofs Heat loss and Heat gain 25-35%.

WINDOWS are one o the weakest points in the building when it comes to heat loss or heat gain. Careul consideration needs to be given to windowplacement and selection. When selecting windows the type o rame and glass that is selected will help keep you cooler in summer and warmer in

winter. Things to consider include thermal breaks in aluminium rames and high perormance glazing that reects heat ow.Windows heat gain = 25-35% Windows heat loss = 10-15%.

EAVES & SHADING East and west-acing windows should be shaded rom the sun by vertical shading devices such as external blinds or shutters. North-acingwindows should always be shaded by suitably designed eaves or pergolas which provide access or the winter sun, while providing shade rom the summer sun.

Natural Day Lighting

The more natural light thatreaches into a building the lessartifcial lighting is needed whichreduces energy consumption andcosts. This provides an advantageor schools as they operatepredominantly during daylight.

Artifcial lighting

Energy-efcient light fttings and uorescent lamps, especiallytriphoshor tubes, are now a standard part o classroom design.Installing the correct sizing o energy-efcient fttings andcontrol systems or artifcial lighting is important. For example,schools now include the zoning o circuits in banks parallel towindows which allow selective use, as well as simple controlssuch as timers and sensors to limit running time.

Passive Solar DesignPassive design uses simple design techniquesthat help control ventilation and the

temperature o a building without usingmechanical systems.

Victorian school acilities are now designed torespond better to local climates. Where possible,buildings are orientated so rooms and windowsace north and south, with east and west-acingwindows minimised. This makes maximum useo the sun and allows or cross-ow ventilation.
