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.
