Cheaper rates from energy suppliers will be pursued for government buildings through an investment of £20 million.
According to the Department of Energy and Climate Change, the money will be taken from a £405 million fund first announced in April's Budget speech and will be used to make sure government buildings use less energy and that carbon emissions are reduced.
Techniques and equipment adopted that proves particularly successful could then be used on a wider scale to help reduce business energy costs throughout the UK.
Energy and climate change minister Joan Ruddock said: "We know it's important to show leadership in this area - if we want everyone else to retrofit their homes it's important government buildings also get some treatment."
She added the money will be allocated to a diverse range of applications, including smart meters.
Installing cavity wall and loft insulation and seeking newer, more energy-efficient white goods are some of the best ways to reduce domestic bills and lower carbon emissions.
