The households consume one third of all energy within the EU, whereof 70% is used for heating Source: The European Commission The target group for Zenergy used 73,9 TWh for heating and hot water in 2008 Source: Swedish Energy Board
Approx. 600 000 Swedish houses currently suffer damages from damp 30 % of the small houses in Sweden have growing mold or mold odour in some part of the building Source: Boverket 2009, Så mår våra hus
There is a ”mold-bomb” ticking behind many of the new-built house facings. The risk-zone includes 95% of all houses with parget facing built during the last ten years. 35% of the parget facings built during the last ten years need to be replaced due to damages from damp. The costs for remedying the damp damages that can affect the indoor environment are estimated to 55-89 billion SEK. Källa: Boverket 2009, Så mår våra hus Source: Ingemar Samuelson adj.

Zenergy SIP Sandwich element U-value of 0,16 W/m 2 °K 17 times more dense than standard sealing layers Very suitable for parget facings ”The material may replace EPS plastic in all building components” Source: Skanska, 2010
Zenergy SIP removes the problem with damp and mold damages Zenergy SIP is completely in-organic and cannot grow mold. It’s a building material in line with the changing building standards. Other insulating materials on the market have a λ-value of approx. 0,037 W/m°C, while Zenergy’s insulating material has 0,023 W/m°C This results in either a reduced energy loss with the same wall thickness......or the same insulating capabilites with thinner walls and less transported material.
Small houses have an average U-value of 0,334 W/m 2 °C whereas Zenergy SIP has a U-value of 0,16 W/m 2 °K Small houses used 31,5 TWh for heating and hot water in 2008 Zenergy SIP is 52 % more effective than the current standard walls in small houses Swedish small houses have the potential to reduce the energy losses through walls with 52% Source: Swedish Energy Board Using the estimation that 15% of the energy is lost through the walls, 2,46 TWh would have been saved in the small houses if they had been built with Zenergy SIP
Sweden’s future without damp and mold damages Prognosis for new housing estate including small houses and apartment blocks: Year 2010, 19 500 ea. Year 2011, 23 000 ea. Prognosis for rebuildings: Year 2010, 1500 ea. Year 2011, 2000 ea. Source: Boverkets prognos för bostadsbyggandet, mars 2010
With Zenergy SIP the usage of resources improves and the maintenance costs decrease
