3) The design and sustainability
Key innovative and low impact design features and sustainable measures for the project at Milldown Primary School.
The teaching areas have been designed for flexibility and intimacy. Emphasis has been placed on maximising the use of natural light and ventilation. Materials have been chosen to provide long-term durability and minimal maintenance. The building uses a biomass boiler to provide heating and hot water.
In addition to the natural ventilation, a night cooling strategy is incorporated to help achieve a good internal environment to assist with pupil achievement. The building also includes a sprinkler fire suppression system with an underground storage tank and rainwater harvesting will be used for flushing 14 toilets.
Predicted running costs:
Predicted electricity consumption taken from the Integrated Environmental Modelling System (IES)- 47.02 kilowatt hours (Kwh)/m2
Predicted renewable energy generation taken from IES - biomass boiler generates 52.7 Kwh/m2
Predicted fossil fuel consumption taken from the IES - gas boiler consumes 23.5 Kwh/m2
Predicted water use - 4 m3/pupil/year
Predicted water use to be provided by rainwater 253m3/year
