HOW BUILDING ENVELOPES HELP TO CONSERVE HEAT AND POWER – PART L


Implementation of the strategy for the conservation of fuel and power is covered by Approved Document L of the Building Regulations.


As a result, our specialists are offering advice and guidance to design teams and building owners on the specification of the building envelope to reduce CO2


emissions by: Retaining heat within the building


Allowing sufficient natural light and useful solar gains into the building


Ensuring that the building does not overheat.


Roof and wall cladding systems manufactured using Colorcoat® pre- finished steel can comfortably satisfy the Part L2 A ‘2013 notional building’ specification for new builds, plus the Part L2 B U-value requirements for work on existing buildings for new and retained roof and wall elements.

Guidance can also be provided where the building owner requires a specification above and beyond what is needed for basic regulatory compliance. This guidance covers the relative improvements and cost effectiveness that can be made by increasing insulation, improving building air tightness and improving building interfaces and details. The cost-effectiveness and relative impact of these measures will vary depending upon building size, type and use.


All Colorcoat® supply chain partners provide building details that have been thermally modelled and have been independently assessed. The cladding system joint configurations have also been assessed for air leakage, enabling design teams and building owners to reap significant benefits.
