The Climate Change and Sustainable Energy Act, which has just received royal assent, thus clearing the final hurdle in its passage through parliament, allows for a dramatic jump in microgeneration and other renewable-energy technologies.
The act - a Private Members Bill, introduced by Mark Lazarowicz, Labour MP for Edinburgh North & Leith - has been welcomed by the RIBA, which claims that it is a victory for its 2005 Manifesto for Architecture.
The new law will provide for a review of the permitted development orders that allow for the installation of microgeneneration technologies, such as domestic wind turbines.
Among those waiting for approval for domestic turbines are Conservative leader David Cameron and Penoyre and Prasad principal Greg Penoyre.
RIBA vice-president for strategy and policy Sunand Prasad said: 'This is a significant success for the RIBA Manifesto, which called for legislation to give people the incentives and encouragement to do their bit to combat global warming.'
'The combination of smarter regulation and improved technology means that architects are now well placed to help people to help themselves and the planet.'
