Tell us what you think of our new sustainability channel and you could win one of four green gift vouchers

Building has launched a green survey for readers to share with us their thoughts on the sustainability channel, which was launched six months ago.

The Sustainability Survey is gathering thoughts on the overall content mix in the channel as well as what are the best sections and key subject areas that we should be looking at in more detail. In return for your valuable views the channel is offering four £40 gift vouchers with Nigel's Eco Store

Site editor Phil Clark said: "We have built up a significant audience in a relatively short space of time and it's important we know the issues and challenges they are facing. Our content needs to reflect the changng market out there for those creating a sustainable built environment."
