Key Objectives of the Code
As recommended by the Sustainable Buildings Task Group
• Bring about a step change in sustainable building practice for new homes, provides a route map to Zero Carbon dwellings
• Encourage home builders to construct more sustainable homes
• Signal the direction of future regulations

Ecology•
A Two-stage Process
• Design Stage– Based on design drawings, specifications and
commitments – Results in interim certificate of compliance
+• Post Construction Stage
– Based the design stage information– Confirmation of compliance through site
records and visual inspection– Code certificate awarded based on compliance
at this stage

Mandatory requirements of the Code
• Ensure that run-off rates and annual volumes of run-off post development will be no greater than the previous conditions for the site. Where rainwater holding facilities/sustainable drainage systems (SUD’s) are used to provide attenuation of water run-off to either natural watercourses or surface water drainage systems, providing percentage time attenuation should be provided as follows to meet the mandatory requirement or the following, whichever is greater:
• 50% in low flooding risk areas• 75% in moderate flooding risk areas• 100% in significant flooding risk areas
