The government says that by 2020 it wants all schools to be "models of energy efficiency and renewable energy" and provide "healthy, local and sustainable food and drink produced or prepared on site".
Similar to geologists evaluating how to produce a reservoir, the efficiency engineers use this comprehensive data to calibrate simulation models that predict the financial impact of a range of efficiency measures over the building life.
