How green is the proposed new Bristol City stadium design?

Saw this Evening Post report about how the proposed new Bristol City football stadium would be 'sunk into the ground' to minimise impacts. Subject to the full details, which I've yet to see, this is likely to be a good aspect of its design as visual intrusion, noise pollution and possibly light pollution would be cut. I made an enquiry to find out more via Trimedia (ashtonvale@trimediauk.com) who are dealing with a lot of the consultation/PR for BCFC and I was told the stadium would be sunk 3 metres into the ground. They also sent me further design information, which I'm looking over, and I sent the email request below for asking about a wide range of green design features/principles:

Thanks for this - I'll look over the attached information asap. I'd be grateful if you could establish which of the following you feel are a part of the BCFC new stadium plans:

*abiding by the concept of compensation for loss of green space in the green belt;

* a thorough ecological assessment of the whole area, at various times of the year;

*walking, cycling and light rail transport links;

*an unobtrusive external colour;

*use of ecological footprinting to measure impacts;

*permanently protected nature reserves around the stadium, designed to maximise biodiversity;

*aiming to be a carbon neutral stadium;

*avoiding any 'sprawl' in design;

*being an example of sustainable design (see examples below) - promoting sustainable economic activity, the latest energy efficiency, renewable energy and sustainable transport technologies.
Examples of football clubs who have used or attempted to use green principles, designs and technologies (this would fit well with Bristol's green capital ambitions and compensate to a degree for the loss of green space):

Dartford FC – living grass roof, solar electricity and heating, rainwater collection and low noise and light pollution design.

Ipswich Town – carbon neutral scheme.

Renewables in football clubs information.

Middlesborough – solar roof and wind turbines project.

Man City – community involvement, transport and waste initiatives (wind turbines were planned but sadly now abandoned).

Many thanks for your help.

Yours sincerely
