I have been asked to reply.
Northstowe predates the eco-towns programme and its planning is already progressing, but we see it as a green exemplar and it will be an advanced prototype for eco-towns. The Northstowe Masterplan is currently being reviewed ahead of submitting the planning application shortly, and the review includes consideration of sustainable energy and high energy efficiency.
In the Eco-towns Prospectus, published on 23 July which mentions the development of the eco-town at Northstowe, we have set out the outcomes we expect to see from eco-towns. These include incorporating renewable energy systems, not just for homes, but schools, shops, offices and community facilities. We have also asked the Town and Country Planning Association to undertake a study into the practical application of the key sustainability and development criteria for eco-towns, which will draw on case studies, such as Northstowe, and this will help us to learn from the experience of others and so inform the development of eco-towns.
