Passive Houses are highly insulated, comfortable, cold bridge free structures that require little heating, they usually have triple glazed windows, heat recovery ventilation (HRV) and high air-tightness levels. It doesn’t cost extra to build a Passive House using our construction methods, as money saved on a complex heating system pays for better windows or extra insulation. Combining Passive House principles with Solar heating reduces the heat demand of a Passive House by 90%.
Our simple, effective, well thought through, construction methods can give builders throughout the UK a competitive edge in the market place because it shows they’re interested in building more efficient houses. This website generates a lot of enquiries from Architects and Clients wanting to build energy efficient houses, so builders who align themselves with Viking House and use our efficient/effective construction methods win projects more easily. With over 100 super efficient construction projects to our name our experience is unrivalled within the Construction industry. We have a number of clients who have come through last winter with heating bills of less than £50.
We’re in regular contact with numerous Certified Passive House Designers throughout the country, so we can put clients looking for an Architect in direct contact with local Certified Passive House Designers. Half the running costs of a building can be saved at design stage with a Certified Passive House Designer.

We work closely with, and follow the principles of eminent Dutch Architect and Engineer, Professor Jon Kristinsson who was awarded the “Shell Queens Prize” for energy innovation in Holland and is known there as the “Godfather of Energy”. In 1979 Jon built the world’s first 183 Passive Houses in Rotterdam , ten years before the first German Passive houses.
We’ve worked previously with Morgan Sindall in the UK, the Quinn Group in the Northern Ireland and Airpacks Ltd as consultants and to upgrade their construction details to provide cold bridge free, condensation free details using standard trades and materials. I delivered a presentation at the 2011 UK Passive House Conference that was well received.

We just renovated this Dublin house to Passive House Standards in 2009 and added a new 90m2 super-insulated Passive House 3 storey Timber Frame extension with an 0.10 U-Value floor, an 0.08 U-Value roof and 0.11 U-Value walls. Before the renovation Olive (the client) described this house as “the coldest house in Ireland” and now its one of the warmest houses in Ireland and she hasn’t turned on the heating since she moved back in last Febuary.

The walls are lined internally with Fermacell and the house is built on a Passive Slab our PassivHaus certified foundation system making it a Thermal Bridge free construction. The HRV Air will be pre-heated in the Conservatory by a few degrees in the Coldest Winter Days.Read More
Passive Slab is Passive House certified to deliver the lowest U-value (as low as 0.08W/m.K) on the market and eliminates the critical wall-floor Cold Bridge. Read More
The radiant interior surface temperatures play an important role in how humans perceive thermal comfort. Radiant temperature asymmetry is key i.e. surface temperatures must be close together. Read More
Our Timber frame Passive Houses usually arrive on site pre-finished with Cellulose Insulation in the walls and triple glazed Passive House windows fitted. The Timber frame walls can be pre-finished internally, so no wet trades are required on site.Read More
The Glengariffe Passive Solar House has a South facing Conservatory that supplies 45% of the heating requirement for the house. It was monitored throughout the entire year of 2005, and data of more then 50 sensors was collected at five-minute intervals. The Active Solar House was used to study the effect of a sunspace (or conservatory) on the performance of the entire building.Read More
