1. Sustainability<br />
Good sustainable practice can<br />
offer numerous environmental<br />
and cost benefits. The potential<br />
cooling and <strong>the</strong>rmal insulation<br />
properties of green roofs can<br />
also have costs benefits for<br />
building owners.<br />

Sustainable urban drainage<br />
systems (SUDS) are widely<br />
used to reduce <strong>the</strong> impact of<br />
urban runoff on <strong>the</strong> aquatic<br />
environment. A permanent<br />
lake forms <strong>the</strong> basis for flood<br />
storage for <strong>the</strong> Quaggy Flood<br />
Alleviation Scheme in<br />

Successful green spaces contribute<br />
towards making more attractive<br />
towns and cities; provide venues for<br />
cultural events and <strong>the</strong> arts; raise land<br />
values; and provide safe routes. Their<br />
ecological functions include providing<br />
flood protection and sustainable<br />
drainage; creating better microclimates;<br />
air filtration; shading; and enhancing<br />
biodiversity. A sports pitch, a nature<br />
reserve or a residential communal<br />
garden should play a more complex<br />
role than its name suggests: all green<br />
spaces should promote a distinct<br />
sense of place and provide a range<br />
of environmental services, accommodate<br />
several uses and provide multiple<br />
benefits. Each of <strong>the</strong> eight qualities<br />
can contribute towards more<br />
sustainable communities.
