Passive House

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%.

The Passive Slab is quicker, simpler and no more expensive than traditional strip foundations, it totally eliminates cold bridging and delivers an excellent 0.105W/m2.K U-value.

Twin Wall Timber Frame with U-values as low as 0.11W/m2.K is quicker, simpler and no dearer than regular 0.20W/m2.K U-value timber frame and totally eliminates cold bridging through the stud.

The Breathing Window simplifies ventilation by removing intricate duct-work which requires annual cleaning, its simpler to install, cheaper to purchase and way more efficient to run than regular HRV.

A Solar Roof is sufficient to fully heat a Passive House, 5-6 days heat can be stored in the concrete slab, it can be cost effectively installed and delivers the lowest annual running costs of all heating methods.

Our simple, effective, well thought through, construction methods can give builders throughout Ireland 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.
