First UK Passivhaus to be built with cavity wall construction. • Design & build project led by Green Building Store. • Denby Dale, West Yorkshire • Private. The Case Study I have chosen is the Denby Dale Passivhaus. The rationale behind this decision was mainly due to the wealth of resources provided. Design Case Study. Denby Dale Passivhaus was built for a private client who wanted a three bedroom detached house, built to a strict budget of £, on an.

It allows for sufficient and comfortable ventilation to all areas of the house whilst minimising the loss of heat gained from the sun, human activity, cooking, showering, electrical appliances etc. The first winter was a very cold winter and we just turned up the heating and the house sometimes overheated up to 26 degrees in the upstairs rooms! Please let us know if you have any case studies, resources or simple actions to share. It optimises heat from the sun and Mechanical Ventilation with Heat Recovery MVHR provides constant fresh air and helps retain the heat inside the house.

Comfort and joy Today the house is a warm and comfortable 21 degrees inside, 10 degrees outside. More information on the Denby Dale Passivhaus, including technical films and a 40 page technical briefing, is at www.

An adhesive-backed airtightness tape was then attached to pzssivhaus plywood with a fleece wrapped into the wet plaster, making the junction between the plywood and plaster airtight. Soon afterwards a new operating system was installed which paxsivhaus helped regulate the boiler better. 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. For more information on Denby Dale, please click here.

He then noticed that a thin grille on the outside of the inlet duct was clogged up with seeds and leaves from the garden. Whatever we do to it, the house runs along performing perfectly, hour after hour, day after day, year after year. Understanding and modelling thermal bridging is becoming absolutely critical to accurately predicting the heat loss of a building.


It was a steep learning curve for everyone and it took us a while to work it all out. What really needs to happen is for Passivhaus to be used for social housing. 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.

We have noticed changes in awareness of Passivhaus over the last 5 years. Passivhaus is up against various vested interests. Skip to main content. Now we need 18… 9 days ago. 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…. The aim passivyaus building this property was to provide the construction denhy with an easy to use template to build a low energy Passivhaus using techniques and materials that are familiar to the British workforce.

In manufacture it uses a high content of recycled glass bottles and requires less overall energy consumption than some alternative products, resulting in less carbon emissions. 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.

Built by Green Building Store’s construction division – Green Building Company – the project is the first certified Passivhaus in the UK to be built using cavity wall construction and has pioneered the combination of British vernacular construction methods with the German low energy Passivhaus design methodology. We are aware that Kirklees Council is exploring a Passivhaus policy for its own land but this has not yet been finalised.

I contacted Cllr Andrew Cooper about projects for social housing with Passive in mind, on Plane Street, Huddersfield 18 months ago and re-contacted him just recently as nothing had happened as far as I know. We welcome your involvement, enthusiasm and engagement – it’s what the industry needs to keep moving this work forward.


If we do passivhaud, society wins, the people who live in it win, the housing passifhaus wins and the planet wins. The project has pioneered the combination of British vernacular construction methods with the German low energy Passivhaus design methodology. Only vested interest could explain the unpersuaded Passivhaus sceptic!

One of our big challenges is getting Passivhaus supported in Government. The data you submit will be solely used by Green Building Store and its approved suppliers to ensure that we deal with your enquiry effectively and provide communications directly relating to your enquiry.

Another airtightness tape was used to seal the gap between the window and the plywood box. Want to see more like this? Where did you hear about us? Thermal bypass refers to air movement through or around insulation, which can reduce its effectiveness. We were able to make a passivhaud savings straight away. Architype Kirklees Media School: In addition to its thermal performance glass passivhauss wool also has other sustainable features.

Many thanks, Murray — Penzance. If rigid insulation is debby and fitted badly with too many gaps, air movement around and between the insulation boards is increased, which can drastically reduce its insulation value. 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.

Has progress been made? The Denby Dale Passivhaus in West Yorkshire has sought to provide a solution to the urgent need to drastically cut the CO2 passivhsus from buildings in the Passivhauz and has tried to create a low-cost and easily replicable template for low energy Passivhaus construction, using techniques and materials familiar to British builders. MVHR is an absolutely integral component for achieving the necessary performance levels needed for Passivhaus buildings.
