Carbon calculator devised for BIM design

4 May 16 Consulting engineer Mott MacDonald has developed what it says is the first carbon calculator capable of measuring the carbon footprints of building information modelling (BIM) designed assets.

The Carbon Portal will help provide a more effective service to clients who recognise the value of carbon reduction, Mott MacDonald claims. It will show where savings can be made at both planning and design stages.

The correlation between low carbon construction and reduced cost was identified in the UK Treasury’s infrastructure carbon review of 2013. Quantifying carbon to establish a baseline is one of the crucial first steps of PAS 2080, a new industry standard on carbon management that provides guidance to those who want to cut carbon in infrastructure delivery.

The Carbon Portal reduces hours or days of calculations to just seconds, it is claimed.  The tool works for water, transport and power assets, with plans in place to cover further sectors in the future, Mott MacDonald says.

The portal is populated with UK data that already supports optioneering in all markets, but datasets are being continually refined and tailored to key regions worldwide.

Mott MacDonald global sustainability leader Davide Stronati said: “As the importance of carbon management increases across the industry, we expect carbon to become fully embedded alongside scheduling and cost details as the sixth dimension of BIM, with automated carbon assessments informing the design process. This will take time, however it will be driven by the many benefits clients are already enjoying by cutting carbon. The Carbon Portal will help us and our clients achieve the low carbon outcomes that the PAS 2080 process supports.”
