Excellent news to hear that David Cameron in addition to very positive comment and slowly improving policy is also walking the walk. Its really encouraging and on the back of hearing that DECC was working on generating windows on it's offices.
The 300-year-old building earned the accolade for a range of improvements undertaken in the past five years, including new boilers, low-energy lighting using motion detection, and using the heat from IT equipment to heat water. There is even a water tank buried underneath the garden for times of drought, where rainwater collected from the building is stored.
Other eco touches include low use water fittings, better insulation, over 90 per cent of construction waste being recycled, and a real-time display on the Number 10 website
which shows how much energy the building is using.
Now that's leadership !
