The organisation backed new legislation on green design in an announcement made yesterday.
Changes proposed by ODPM include minimum standards for water and energy efficiency and a move to reward the use of renewable technologies in residential development.
The RIBA has claimed it was pivotal in steering the government's stance on the draft 'Code for Sustainable Homes'.
The RIBA's president Jack Pringle said: 'While a number of issues still need to be addressed, I am glad that the government is prepared to engage with the industry on this important project.'
The government has also supported amendments to the Climate Change and Sustainable Energy Private Members Bill to support 'micro-renewable technology'.
The Bill is currently at the 'report stage' in the House of Commons.
