Reduce energy demand

Approaching the energy demands of the built environment should be viewed as a two stage process: first, minimise the amount of energy consumed and deliver the energy efficiently.

Then consider low carbon and renewable technologies.

Emissions reductions from investing a set amount in energy saving are nearly always greater than those from investing the same amount in new low or zero carbon energy generation and distribution systems. Because we are still at such an early stage of implementing sustainable energy strategies, especially with regard to existing buildings, Pareto’s (80:20) Rule applies: a large proportion of benefit can be achieved from a relatively small effort.

The Climate Change Act means CO2 emissions must be cut by 80 per cent from 1990 levels by 2050. This will require both a massive reduction in energy use and a massive increase in low carbon and renewable energy production - but the quickest wins are from energy demand reduction.

Cities are supported by a strong national policy programme with high carbon reduction targets. Planning and building control departments need to develop the specialist skills and knowledge to achieve low carbon development. Energy use of existing buildings is a key area for local authorities to address. Ensuring that homes, jobs and facilities are all located in places that promote sustainable travel can also reduce energy demand.

In the current economic situation, reducing energy demand and therefore energy bills makes sound economic sense for local authorities, residents and businesses and can help reduce fuel poverty.
