Yesterday MP Alan Simpson criticised the deputy prime minister's vision, labelling the government 'intellectually out to lunch'.
Simpson, MP for Nottingham South, said: 'The £60k House competition is not required to meet current energy-efficiency standards.
'There's no sense at all in giving approval of the construction of houses that would be too hot in summer and too cold in winter. It adds to carbon emissions and makes matters worse.
'It's a classic example of stealing cheaply from today what we will have to pay dearly for tomorrow.'
The RICS urgently raised the concern on Wednesday with environment minister Elliot Morley in the House of Commons.
This sentiment was echoed by Jenny Saunders, from lobbying organisation National Energy Action. The group is concerned about the effects of the regulations omission on heating low-income households and is also part of the cross-party Warm Homes Group with the RICS.
