Ecopassiv – Passivhaus compatible windows. What really needs to happen is for Passivhaus to be used for social housing. However, the client did receive a grant to install solar thermal panels for hot water. Understanding and modelling thermal bridging is becoming absolutely critical to accurately predicting the heat loss of a building. You have to experience the comfort of a Passivhaus for yourselves to understand how different it feels from a standard building.

We have always debby that we wanted to make the Deny Dale Passivhaus available to visitors as a resource. One of our big challenges is getting Passivhaus supported in Government.

MVHR is an absolutely integral component for achieving the necessary performance levels needed for Passivhaus buildings. Economics, performance, availability, ease of fitting and reducing thermal bypass were all among the benefits of the Knauf Insulation products chosen.

We welcome your involvement, enthusiasm and engagement – it’s what the industry needs to keep moving this work forward. The Denby Dale Passivhaus’ design and construction pays particular attention debny junctions, which are always difficult for airtightness because of the differential movement between different materials.

All new housing should be Passivhaus but if you are going to prioritise anything it should be social housing.

Many thanks, Murray — Penzance. Our gas bills are slightly more over the winter as it is also used for domestic hot water heating when the thermal hot water solar panels are not in operation.

I did more or kess the same in my house 20 years ago and am equally happyno energy bills at all many solar panels and the most comfortable house one can imagine. The house runs itself. He immediately removed the grille and the system worked fine. Glass mineral wool was specified over rigid insulation to ensure a tight thermal fit. Only vested interest could explain the unpersuaded Passivhaus sceptic!

It was a steep learning curve for everyone and it took us a while to work it all out. Maximising airtightness Passivhaus buildings require very high levels of airtightness 0. Super insulation is fundamental to Passivhaus construction, along with close attention around junctions of these elements.

Whatever we do to it, the house runs along performing perfectly, hour after hour, day after day, year after year. We dalle away to a country cottage in Cornwall a couple of years ago.

We like to hope that those visits have helped people on their Passivhaus journey, just as were we helped when we first visited Passivhaus homes in Austria.

Minimising thermal bypass Thermal bypass refers to air movement through or around insulation, which can reduce its effectiveness. It wins on comfort, it wins on cost, it wins on sustainability. It is incredibly encouraging to see how much Passivhaus has grown over the 5 years and to compare where it was then and where it is now….


Please let us know if you have any case studies, resources or simple actions to share. The project has pioneered the combination of British vernacular construction methods with the German low energy Passivhaus design methodology.

If rigid insulation is used and fitted badly with too many gaps, air movement around and between the insulation boards is increased, which can drastically reduce its insulation value. Earthwool DriTherm Cavity Slabs are flexible enough to eliminate air gaps and prevent heat loss due to their inherent ability to knit together at joints between the slabs.

The design team preferred to put resources into Passivhaus energy efficiency measures rather than micro-renewables.

Where did you hear about us? Earthwool DriTherm Cavity Slabs are BBA Certified for all exposure zones and formally guaranteed for 50 years to prevent the transmission of liquid water from the outer masonry leaf to the inner masonry leaf. Has progress been made?

The aim of building this property was to provide the construction industry with an easy to use template to build a low energy Passivhaus using techniques and materials that are familiar to the British workforce.

A local Green Party councillor Andrew Cooper has been working on a policy to introduce Passivhaus as a requirement on any land sold by Kirklees council. Hopefully this will come to fruition soon!
