Green Roofs

Volume 707: debated on Tuesday 3 February 2009


Asked by

To ask Her Majesty's Government whether they will increase financial and other support to promote the use of green roofs on commercial buildings and private dwellings. [HL980]

The Government provide no direct funding to promote the development of green roofs. However, the Government are committed to moving towards more sustainable low-carbon buildings that are more energy and water efficient, and support our wider climate change and sustainability goals.

The Government are particularly supportive of the use of green roofs as they increase and facilitate the use of sustainable drainage systems (SUDS). SUDS provide an effective control of rainwater runoff at source, freeing up capacity for drainage in the below-ground system, as well as benefiting water resources through groundwater recharge, rainwater harvesting and helping to improve water quality.

Those building homes to the sustainability standards set out in the code for sustainable homes may incorporate green roofs to achieve the surface water management, energy efficiency and ecology credits. Financial incentives available to encourage building to the code include the stamp duty land tax exemption for those who reach zero carbon/level 6. In addition, those new developments built on Homes and Communities Agency land or funded through the Government's national housing affordability programme are required to meet level 3 of the code for sustainable homes.
