Currently there is no scheme for existing buildings to prove their energy credentials, with Energy Performance Certificates only applying to the sale of homes across the UK.
A spokesman for the DIUS said there is a direct link between people in "dwellings with high energy efficiency standards" and a reduction in energy bills.
He added: "An annual or biennial assessment would encourage households and firms to think about energy performance on a regular basis."
The Energy Saving Trust recently found that 53 per cent of homeowners would be willing to pay a higher premium for green homes, claiming they would handover an average of £3,350 for an energy-efficient property.
