Gensler boss urges Government to allow energy inefficient offices to be turned into flats or hotels to save tonnes of wasted carbon

Swathes of secondary offices risk being torn down unless the Government relaxes the planning system, Gensler鈥檚 director of consulting said this week.

Hugh Mulcahey told a 30-strong crowd at the top three architecture firm鈥檚 Aldgate HQ that increased environmental benchmarking, including EPCs, BREEAM and LEED rating, would lead to large scale sell off of energy inefficient buildings.

Mulcahey, a consultant with DTZ and Donaldsons before joining the US-based studio, said property that will stay empty or be demolished unless the Government allows for a change of use in the planning system to residential use or hotels.

鈥淲e will have one hundred million people living in this country later this century,鈥� he said, 鈥渁nd they鈥檒l have to live somewhere. Relaxing the planning system would help ease the housing shortage as well as saving carbon emissions. But at the moment, local authorities don鈥檛 respond well to change of use.鈥�

He said leading them through the carbon saving argument had the potential to "change the minds of the most stubborn of local authorities."

We have one hundred million people entering the country this century and they鈥檒l have to live somewhere.

A powerful argument

Graham Nickson, policy and projects manager at the Town and Country Planning Association, said Mulcahey had raised a 鈥榩owerful argument.鈥�

鈥淩euse and refurbishment are preferable in terms of carbon saving. We can also begin to save some of the character of an area. After all, these buildings have been there for thirty years and are part of the townscape. If we can use it for a hotel rather than a disused cardboard factory, so much the better.鈥�

He said allowing for reasonable change of use in a local area had other benefits. 鈥淲e want a townscape that is flexible and responds to market pressures of the locality. You should be able to convert a garage in the back to one type of business but, if that doesn't work, then try another. Having to apply for changes of use all the time is a nuisance.鈥�

Instead, the forthcoming Planning Bill 2008 contains the creation of the new Infrastructure Planning Commission, which critics say is anti-democratic and a sop to business. But the Government wants to introduce it to help shepherd large projects, such as power stations, more quickly through the system.

It recently removed rebate relief from empty offices. Landlords will now pay full business rates after an initial three-month grace period. Business relief for vacant properties cost the taxpayer 拢1.3 billion last year.
