Changes to Carbon Checker following release of SBEM 5.2d

Approval of revised Carbon Checker following release of SBEM 5.2d (updated)

A new version of Carbon Checker ( has been released to support SBEM 5.2d patch 1.

The change from SBEM 5.2b to 5.2d only added features that support calculations in Wales; calculation results in England are unaffected by this version change.

We have had approval for our 5.2d-compliant version of Carbon Checker for use in England and Wales.  

The situation is potentially confusing, so it is summarised below:

As well as implementing the change to support SBEM 5.2d, the new version of Carbon Checker lets users globally edit glazing and window settings for a project rather than having to change them individually.

Carbon Checker 1.8.0 and SBEM 5.2b

Due to delays in the approval process for new software tools using the SBEM version 5.2b engine, DCLG have extended the period where they will be accepting lodgements carried out using the 4.1e SBEM engine. The new cut off date for lodgements under the old version will be midnight on 5th June 2014.

For our users this means that will be able to continue to use Carbon Checker 1.7.3 until this date.

We have completed work on the new version of Carbon Checker (version 1.8.0), which incorporates the new version of SBEM and will be making it available to download for our users next week.
