The move by the UK-GBC - whose members include housebuilder Barratt, contractors Laing O'Rourke and Sir Robert McAlpine, and developer Stanhope - will target environmentally-unfriendly office blocks.
UK-GBC partners office rental giant Land Securities Trillium (LST) for the initiative, and Norman Greville, managing director of LST's capital projects group, said it was the 'first time that practical tests' would be used to 'provide a user-friendly guide for the construction industry.'
Greville told the AJ's sister publication Construction News: 'The tests will look at buildings from the 1960s, 1970s and 1980s and at the impact of temperature sensors and air conditioning in buildings to see how energy consumption can be reduced.' He said that the results would be available by the end of the year.
The move to combat existing buildings' carbon emissions - which account for half the UK's total - is on the back of another UK-GBC project announced this week for the Department of Communities and Local Government (DCLG), which examines ways that energy standards can be introduced for new, non-domestic buildings.
UK-GBC will report its findings to the DCLG by October, with a consultation document expected by the end of the year.
