PAS 2035 is the new over-arching document in the retrofit standards framework that provides a specification for the energy retrofit of domestic buildings, and details best practice guidance for domestic retrofit projects.
Build Test Solutions was one such organisation involved in the preparation of this new PAS document; contributing some of their own technical insight to help build a new standard for the future.
Initially set to underpin Government-backed retrofit schemes carried out in the UK, the standard adopts a risk based approach to retrofit assessment, design, measurement, verification as well as the provision of handover advice:
Build Test Solutions response to new PAS 2035 document:
PAS 2035 combined with PAS 2030 (which concerns installation, testing commissioning and handover) stands to serve as a real game changer in the way that retrofits are designed and assessed. As strong advocates of building performance measurement and post occupancy evaluation, BTS were eager to see that air permeability testing, heat loss measurement and ventilation system assessment were all part of the retrofit design and commissioning process. Measurement of performance pre works can ensure that the most appropriate solutions are designed and installed whilst post works measurement will ensure that intended quality outcomes have been delivered. Our own Pulse air permeability measurement device, leak checker fan, Smart HTC and rapid U-value measurement have all been developed for quick and easy use within a Retrofit projects.
