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 heating system can often pay for better windows, HRV and extra insulation.

• Passivslab is quicker, cheaper and simpler than traditional strip foundations, it eliminates cold bridging and delivers an excellent 0.105W/m.K U-value.
• Warm Stud 0.08W/m.K roof is quicker, simpler and cheaper than a regular 0.18W/m.K U-value roof and eliminates air-tightness tapes and membranes.
• FiWi HRV is quicker, cheaper and more efficient than regular HRV and simplifies ventilation by removing intricate ductwork runs that require annual cleaning.
• Solar Slab delivers 100 days free heating to a Passive House by inter-seasonally storing the summer’s sunshine.

"Spend €1 on insulation to save a Kilowatt or spend €10 on solar panels to generate a Kilowatt"

We take the guesswork out of specifying components by verifying your design through the Passive House Planning Package (PHPP), which allows us to analyze various combinations of wall build up, window frame U-value, cold bridge factors and heating systems to maximize the bang for your buck. Viking House provides a full contract for turnkey delivery of low energy buildings or the Passive House Self builder kit, with finishes by your own local tradesmen. This is proving to be an extremely cost effective solution for today's market.

We can analyze your project from the macro issues such as siteing and solar orientation of your building to the micro detailing to condensation risk, and heat loss analysis of fabric build-up. We are currently engaged with designers and builders including Morgan Sindall in the UK, the Quinn Group in the North and Airpacks Ltd to upgrade their standard details to provide cold bridge free, condensation free construction details using standard trades and materials.
