The 6,000 home scheme titled Middle Quinton has sparked huge opposition from the community with leading actors such as John Nettles and Dame Judi Dench speaking out against the plans.
But, Ian Ward from SABRE, a joint venture between Sheffield University and BRE (the Building Research Establishment), has this week emphasised the energy conservation aspects of the project.
Mr Ward, who has been recruited to advise the team working on the eco-town plans at Long Marston, said: 'Depending on the materials used and the heating system selected, it is perfectly realistic to dramatically reduce the amount of energy needed to heat homes and offices.
'I would go as far as saying that it will be possible to heat a family home for less than £100 per year, perhaps as low as £50 in the best circumstances.'
The proposals – put forward by regenerations specialist St Modwen and developer the Bird Group - were rejected unanimously by Stratford-on-Avon District Council in May..
The environmental credentials of the development for up to 20,000 people include the generation of electricity from the town’s domestic and industrial waste and sewage, solar water heating, high insulation standards, heat recovery ventilation and design emphasising solar gain.
