"When you've spent half your political life dealing with humdrum issues like the environment, it's exciting to have a real crisis on your hands."
Margaret Thatcher- 1982, commenting on the Falkland Islands War .

"What we are now doing to the world … is new in the experience of the Earth. It is mankind and his activities that are changing the environment of our planet in damaging and dangerous ways.
The result is that change in future is likely to be more fundamental and more widespread than anything we have known hitherto.
Change to the sea around us, change to the atmosphere above, leading in turn to change in the world's climate, which could alter the way
we live in the most fundamental way of all”.
Margaret Thatcher- to the UN general assembly, November 1989

UK Government
And European Policy
& the Zero Carbon Agenda
The Government is committed to implementing ‘zero carbon homes’ from 2016.
The Department for Communities and Local Government (DCLG) will publish a detailed plan, setting out its response to the 2012 consultation on the energy efficiency requirements in building regulations, by May 2013.
The Government will then consult on next steps, including on the means of delivering allowable solutions by Summer Recess.

Additional Considerations
Site Conditions:• Access • Location (regional weather)• Ground conditions • Flood risk• Existing trees, water bodies etc• Local energy resource – source for biomass, wind conditions etc• Existing district heating network
Planning:• Dwelling type mix/ density• Built form considerations - roof pitch, building height etc• PV and solar panels • Local Renewable targets
Site Layout:• Dwelling types• Design for solar technologies:
• Orientation for solar technology• Roof pitch• Over-shading
Other: • Localism
