A study by Knight Frank says the building industry is willing to engage with the measures but lacks a final definition of zero carbon to fully prepare.
It also claims that there is a perceived mismatch between the drive for zero carbon and the need to raise development volumes.
"The localism agenda is set to hand greater powers to communities. But it will be interesting to see how many agree to have renewable energy plants on their doorstep," declared Frank Knight head of residential research Liam Bailey.
"Meanwhile, the government pledge to ensure that all newly built homes are zero carbon by 2016 has been retained. The detail, particularly on construction, renewable energy and changes to the planning system, is both complex and confusing," he added.
