On 15th March we'll be collaborating again with The Green Register opening up our site at Eastrip Lane, Colerne for a Futureproof site visit and talk about this contemporary three-bedroomed timber frame house built to Passivhaus standards. The topics discussed in this tour and talk - materials used, MVHR, airtightness and methods of construction - are just as relevant to retrofit as new build projects. The building is timber frame constructed on site from 360mm timber I-beams and wrapped in 100mm Pavatex woodfibre boards. The external faces will be either render or geometric cement sheet panels, whilst the roof is anthracite corrugated cement sheet. Windows are from Internorm (Passivhaus certified). All walls and roof will be insulated with Warmcel 500 Cellulose insulation. The building is still under construction and so during the visit, it will be possible to see all aspects of the building fabric: air tightness layers, MVHR ducting, timber frame and Pavatex wood fibre. Places are limited. Visit The Green Register website for full details and to book online.

It was an exciting day for clients Terry and Frank at our Passive House project in Nailsea this week, as they met with Richard Simon, Director of Solarsense and energy consultant Piers Sadler to hand over the renewables package prior to commissioning and learn how the various elements of the system work, using the latest technology.  Richard Simon, Director of Solarsense, demonstrates the smartphone technology that operates the renewables package for clients Terry & Frank's new Passive House while energy consultant Piers Sadler looks on. The package includes a whole roof integrated 7.3KW PV system, a Mitsubishi air source heat pump with thermal store and the latest TESLA battery – Powerwall 2 - for storage. Once registered with TESLA all the data can be monitored via an App on a smartphone, laptop or tablet. The house, which achieved preliminary air test results of 0.27ACH back in February is almost complete and ready to be signed off as a certified Passivhaus - the first in the wider Bristol area.
   Lots going on at our Passivhaus build in Nailsea currently - underfloor heating going in, MVHR installed in the loft, with boards to hold in extra insulation. This home will be seriously snug and warm for its owners come next winter!
