Compliance with Part L2 and Section 6

Tas was the first DSM to be approved for L2 calculations, and the consultancy department is experienced in modelling a wide range of building types and systems. Tas is also accredited for Section 6 of Scottish Building Regulations.

For naturally ventilated areas, the consultancy department can first analyse a selection of zones for overheating then use the same 3d model to carry out the L2 analysis on the whole building.

Tas calculates whether the CO2 emissions of a building comply with Part L2 as well as determining whether the constructions and services are compliant. If the building fails to comply then we can suggest areas for improvement.
