Building performance assessment protocol for timber dwellings—conducting thermography tests on live construction sites

This paper introduces the pan-Wales (UK) Home-Grown Homes (HGH) project (2018 to 2020) which focusses on three areas of improvement for delivering high performance, affordable and healthy homes. The HGH project is funded by Powys County Council, through the European Regional Development Fund’s Agricultural Stream. The HGH project is being delivered by Woodknowledge Wales in a consortium with Cardiff Metropolitan University (CMU), TRADA and Coed Cymru, with seven work packages. ‘More and Better Homes from Wood’ (work package (WP) WP3) focusses on the assessment of building performance for dwellings using timber, and is being delivered by a multi-disciplinary team at CMU through the Sustainable and Resilient Built Environment (SuRBe) group. This paper discusses the context and need for the HGH project as Wales launched its low carbon agenda in March 2019. The focus of this paper on introducing the building performance assessment (BPA) protocol to be implemented by SuRBe across several housing case studies in Wales, through the design, in-construction and occupancy phases, to address thermal and fire (TaF) performance issues, and impacts on occupants’ quality of life, comfort and safety. Preliminary results of in-construction testing on a live construction site are presented, with the challenges of conducting thermography tests whilst construction is in progress and weather conditions in spring in the UK (April 2019). This paper will be useful for academics, architects, building contractors, housing developers and professionals undertaking building performance assessment and evaluation on live construction sites.
