Hanham Hall – Zero Carbon Challenge



Barratt Homes



Hanham Hall – Zero Carbon Challenge, Bristol, UK



Hanham Hall is set to be the first large scale zero carbon eco-village in the UK. It consists of 188 dwellings with a mix of tenure and size ranging from one to four beds.


Conduct a Code for Sustainable Homes Assessment and obtain a "Level 6"—Zero Carbon—sustainability rating.


EcoConsulting was appointed to work in conjunction with HTA, Arup, and Barratt Homes in delivering a Code Level 6. Solutions have to be practical, cost-effective, and carbon-neutral.

We are advising the design team and client on general sustainability strategies and detailed considerations all of which are crucial on a development where over 90% of the available Code credits need to be obtained.

The development will feature a biomass CHP to meet 100% of the heating, hot water, and electrical loads of the dwellings. Very low mains water consumption will be ensured through low flow sanitary fittings and rainwater collection—which will also be used to irrigate the planting.

Did You Know?



The Code for Sustainable Homes uses a 1 to 6 star rating system to communicate the overall sustainability performance of a new home. 



Achieving a Code Level 6 rating implies an extremely energy-efficient -- virtually zero-carbon -- and auto-sufficient house, with minimal water consumption devices and rainwater collection or grey water recycling systems. Other stringent eco-building requirements need to be designed in, to minimize the environmental impact of the building on the land and improve the internal well-being of its occupants.
