When we started work on the SusCon Academy (a sustainable construction training institution), our brief was to use specific materials in order to deliver the performance needed.
This not only included thermal performance in winter, but prevention of summer overheating with correct acoustics too.
The materials that we used in the project were new to the contractor. We were able to advice and offer training on ways to best implement them into the structure and provide information on the benefits of using natural materials.
The project was a mixed build of timber and concrete with the majority of the structure being timber frame with concrete running through the “spine” of the building. Some of the elevations were clad with timber while some had a rendered finish. The products NBT supplied were Diffutherm Woodfibre from Pavatex, which was rendered with Baumit, and Pavatherm Plus for the areas that were clad, which requires no external membrane. Both solutions are BBA certified and not only deliver thermal performance, but also provide a fail-safe solution against moisture build up in the building fabric, whilst significantly reducing the vulnerability the light weight structure has to summertime overheating.
Upon completion, the SusCon Academy achieved the highest ever BREEAM rating for an educational building. BREEAM is the world’s leading method of assessing, rating, and certifying the sustainability of buildings.
