Property Group Sustainable Design Heating and Ventilation Use of high thermal mass and solar shading to absorb heat gains, flattening peak temperatures Natural ventilation, supporting night cooling to reducing the effects of solar gains Heating and ventilation systems are zoned to suit building orientation, curriculum use and out of hours use. Use of building energy management system (bems) controls. Use of heat recovery on mechanical ventilation systems. Use of high efficiency gas-fired condensing boilers

Property Group Sustainable Design Water Rainwater harvesting for W.C flushing and grounds maintenance usage SUDS – Sustainable Urban Drainage Systems Infra red sensing taps to toilet washbasins Urinal flush controls and dual flush / low flush W.C’s

RAINWATER RECOVERY Ormskirk School 55,000 litres below ground Equal to 10,000 toilet flushes

Property Group Sustainable Design Electrical Automatic lighting controls in teaching areas and for external lighting. Automatic speed control of fans and pumps to match load demand and minimise energy consumption Minimised use of electric hand driers and point of use hot water heaters
