Code 2010 the finer points

On the whole one can expect to lose credits when swapping from Code 2009 to Code 2010. The main implications on the credit scores are listed below: This summary was prepared by my colleagure Clare Murray.

Energy

Ene 1 – Less credits are available for the same dwelling when moving from the 2009 to the 2010 version. I.e. A code level 4 dwelling used to achieve 8 credits for Ene1 (44% improvement), whereas it would now achieve 3 (25% improvement). To add to this, the credit weighting for energy section has also gone down from 1.26 to 1.17 making the credits achieved worth less. In the case of a code level 4 building 6.57 credits would be lost after the weightings are applied. To achieve 8 credits in the 2010 Code an 85% improvement would be required.
The credit weighting applies to all credits scored in the energy section, therefore all previous credits will be reduced by 0.09 per credit.

Ene 2 – It is likely that credits can be gained in this section. The implications of thermal bridging and Fabric Energy Efficiency Standards have yet to be fully clarified.

Ene 3-9 – The scores from these sections remain mostly unchanged apart from the reduction in the credit weighting.
Something to note for Ene 8 (cycle storage) is that it appears that non fully enclosed cycle stores are no longer compliant for communal use. I.e. three sided structures with roofs no longer comply.

Water

Wat 1 & 2 – No change to credit scores.

Materials

Mat 1, 2 & 3 – No change to credit scores.


Surface Water

Sur 1 – A surface water drainage engineer is required to determine the implications of the changes to the SUDS credits.
Sur 2 – No change to credit score.

Waste

Was 1 – Compliance with the new inclusive design principles (IDP) checklist is required. This checklist has been applied to Was 1, Was 3 and Hea 3 and deals with access issues for residents.
The credit weighting has also changed in this section from 0.91 to 0.8, causing a general loss of credits.
Was 2 – The Site Waste Management Plan will need to be revised following the updates to achieve 1 of the 3 credits in this section. To achieve the remaining credits available either 50% (for 1 credits) or 85% (for 2 credits) by weight or volume of non-hazardous construction waste generated by the project needs to be diverted from landfill.
Was 3 – Compliance with the new inclusive design principles (IDP) checklist is required.

Pollution

Pol 1 & 2 – No change to credit scores.


Health and Well-being

Hea 1 &2 – No change to credit scores.
Hea 3 – Compliance with the new inclusive design principles (IDP) checklist is required.
Hea 4 – Dwellings will need to be able to meet the new Lifetime Homes Criteria to achieve 4 credits. For developments on steeply sloping sites 3 credits have been made available.

Management

Man 1, 2, 3 & 4 – No change to credit scores.

Ecology

Eco 1, 2, 3, 4 & 5 – No change to credit scores.
