On Tuesday 18th May 2017, Go Green and Low Carbon South West hosted engineers Max Fordham and energy assessors Darren Evans to discuss the performance gap and how they have approached efficiency and regulations in some of their recent projects.

Matthew Tudge, GM for Low Carbon South West, welcomed guests to the Future Economy Centre and gave a brief introduction to both Go Green and Low Carbon South West before swiftly handing over to the morning’s first speaker.

Henry Rock-Evans, Senior Engineer at Max Fordham, started off by giving an overview of their sustainability credentials and values and how they are implemented wherever possible across the company. Henry then delivered a comparison of some current certification options for construction including Passivhaus, BREEAM and the WELL standard as well as some of their possible limitations. Max Fordham have created their own sustainability matrix which incorporates the best features of existing standards and adds an element of practicality and flexibility, as well as the inclusion of ongoing performance measurement beyond expected design characteristics.

Henry then went on to discuss the building performance gap and how they approached it in their design of the new Keynsham Civic Centre. Using their own sustainability matrix, they managed to address the specific requests of the client and be able to deliver end results meeting the client’s energy performance expectations for the foreseeable future.

Our second speaker of the morning was Michael Brogden, technical director at energy assessors Darren Evans. Michael began by giving a summary of the Part L 2016 consultation and available compliance tools to assist companies in meeting their requirements, including SAP (Standard Assessment Protocol) and SBEM – the Simplified Building Energy Model. He then went into further detail on three proposed amendments in the consultation: loss within heat networks, thermal bridging, and hot water methodology – specifically how shower performance is considered – discussing their impacts on the construction industry and rigorousness in planning.
