The investment will be delivered over the next 10 years in a programme designed to transform aging houses. The measures are outlined in the Sustainable Housing Strategy, a blueprint for reduced heating costs and improved efficiency in homes across Scotland.
It is linked to the consultation on the Energy Efficiency Standard for Social Housing, which proposes setting a minimum energy efficiency rating to be met by social landlords.
Cabinet secretary for infrastructure and capital investment Alex Neil said: “Scotland's housing stock is responsible for more than a quarter of our carbon emissions, which is why it is essential that measures are put in place to improve the energy efficiency of our homes.
“An estimated 658,000 households were in fuel poverty in Scotland in 2010, or 28% of households.
“These strategies provide a great opportunity for Scottish businesses and can provide a real boost to our economy. Working with the energy companies, we plan to ensure investment of over £2 billion pounds is provided over the next ten years to ensure our housing stock is energy efficient.
“New technologies, which would bring down carbon emissions as well as household fuel bills, are key to energy efficient homes and a vital element in economic recovery.”
“The drive to transform new-build through innovative design and construction approaches creates economic and export opportunities for Scottish companies, along with an opportunity to make greater use of Scottish timber in innovative products.”
