We provided the first survey of the stripped out building for John Gilbert Architects.
We were asked to provide specialist input relating to the water ingress and causes of decay affecting the building as it was being stripped out. Previous poor quality work was identified including previous attack of dry rot and wet rot and plastic sheeting applied to the solum by a damp proofer which would have caused severe damage if it had been left much longer. This was combined with the almost ubiquitous drilled chemical injection even though the subfloor vents were closed.
EnerPHit standards are achieved primarily by high levels of insulation and preventing hear loss. Obviously this will also prevent air flow and evaporation so carefully designed extraction and passive (passivhaus) systems have been designed to be installed and are to be automated so removing most inputs from the occupiers.
EnerPHit is applied to existing buildings where Passivhaus is the standards for new builds. New builds are obviously easier to achieve the necessary standards but it is extremely difficult to achieve similar performance in an existing building especially in a sandstone tenement block that is around 120 years old.
