This graph shows that over 30 years €200k+ can be saved from your heating and mortgage costs when you build a Passive House instead of a 2005 building regs house. The only logical conclusion is to borrow 10% more money and build a Passive house or build a Passive house that is 10% smaller for the same price! The graph drops off after 30 years when the mortgage is paid but the couple who built the standard house (Red Line) still have high energy bills and they will be soon retiring with their income halved. This graph shows 2 people working to pay the heating and mortgage, imagine the situation after 5-10 years with only one person working and 80% of the income going to pay the heating and mortgage in the standard house.

Passive Poroton House: This is ideal for customers who prefer a block built Passive house due to the many advantages Poroton has to offer like decrement delay, breathability and total elimination of cold bridges. We build the Poro

ton blocks on our insulated foundation system which totally eliminates Cold Bridges between the wall and the floor. The roof is usually insulated with Dense Cellulose and Softboard which prevents summer overheating and slows down heatloss. The Softboard eliminates Wind Chill preventing wind from blowing trapped heat out of the insulation.
