Holistic house modernisation
instead of tackling individual building elements.
90% energy saving.
Fully exploit the potential!
We are facing a global turning point. Saving energy and using it consciously is more important than ever.
While the use of vehicles or the burden of our meat consumption is already being discussed and partially regulated, there does not jet seem to be enough focus on the huge savings potential in housing. One third of our energy consumption is caused by buildings – during the initial construction as well as in our daily living.
When it comes to new buildings and renovations, many property developers advertise reasonable costs and refer to state subsidies. They talk about energy savings of 20 or 30%, which might seem like a big improvement to the consumer. The fact is, however, that we are technically able to save 80% in energy consumption for new buildings and 90% for renovations. This is why it is important that construction projects are approached holistically.
It might initially seem more reasonable for the wallet to tackle individual elements (wall, roof, window) of the dwelling. Here wrong advice is given in the market. Yes, a house consists of individual walls, roof and windows, but energy efficiency can only be ensured by considering all of the elements as a whole. It is therefore actually cheaper to approach a new building or renovation project with the highest energy standard as a target, so that from day 1 the energy costs are only 10% or 20% of what people are paying normally.
Through a holistic building modernization, we ensure that you receive the maximum possible funding and benefit in the long term.
The video from AK61 “Holistic building renovation with the smartshell Reno”, presented by Franz Freundorfer, offers a deeper insight into this pioneering method.
Modern, simple calculation programmes realistically compare the renovation costs and the energy savings for the building to be renovated. The energy saved exceeds the capital costs of the renovation.
Presentation 27th International Passive House Conference Innsbruck Franz Freundorfer
Après que smartwin ait acquis une reconnaissance mondiale dans le développement de fenêtres avec les produits innovants de la famille smartwin, les inventeurs de fenêtres franchissent une nouvelle étape vers des bâtiments économes en énergie et en argent.
Le démarrage de la famille smartshell commence avec quatre produits certifiés par le Passive House Institute. Ceux-ci sont appelés châssis en bois smartshell G, smartwin timberframe E, smartshell solid et smartshell reno.
En étroite collaboration avec certains constructeurs de maisons en bois massif et en bois massif, les partenaires de smartwin offrent désormais à leurs clients la totalité de l’enveloppe de maison passive à partir d'une seule source en plus des fenêtres mondialement reconnues.
La collaboration serrée des acteurs de la construction offre un potentiel d'économies inimaginable. Cela devient particulièrement clair avec le système certifié EnerPHit smartshell reno.
Pour la première fois dans le monde, le cadre de la fenêtre est complètement supprimé et le châssis de la fenêtre est simplement accroché dans le mur reno smartshell rénové.
