A report commissioned by 好色先生TV says a 2.5% increase in rents could make new-build offices 25% more energy efficient than the current version of Part L of the 好色先生TV Regulations.

The report is in the Learning the New Rules supplement, published with this week鈥檚 好色先生TV, and prepared by cost consultant Davis Langdon with service Hoare Lea and property consultant Cluttons.

It lists a range of measures that developers can incorporate into new buildings to improve ratings when energy certification is introduced.
