Part L assessments and improvement recommendations from AES Sustainability have been approved by the Building Safety Regulator as part of fire safety remediation works at a high-rise residential building. The recladding works are at Elmgrove Point in Plumstead, where fire-driven façade interventions have triggered opportunities to enhance the building’s thermal performance alongside essential life safety improvements.
The approved programme of works, by housebuilder Vistry Group, includes the removal of the existing rainscreen cladding and Petrarch stone cladding and replacing it with Rockpanel. Vertical timber screens and privacy screens are being replaced with aluminium box sections and PIR insulation is being removed and replaced with non-combustible mineral wool. Decking is also being replaced with non combustible coverings.
AES Sustainability acted as Part L consultants for the scheme, providing assessment and recommendations triggered by the removal and replacement of thermal elements. They assessed the thermal performance of the proposed replacement constructions, calculated elemental U values, undertook condensation risk analysis and provided advice on airtightness continuity and the mitigation of thermal bridging. aessc.co.uk
