Leaders of the new Green Construction Board highlighted the domestic retrofit market as a major growth area during their first meeting.
The board is co-chaired by Business Minister Mark Prisk and Lend Lease Chief Executive Dan Labbad.
Both are now committed to persuading sceptics that sustainable construction can lead industry growth.
Prisk said: “The potential for low carbon growth is enormous.
“There are approximately 25 million existing homes to be retrofitted by the end of 2050. This is a huge business opportunity that small construction firms should grasp.
“We want to seize these opportunities, which is why we have established the Green Construction Board so that Government and industry can work together and make the most of those opportunities.”
