Passive House renovation

In the colder parts of the world houses use a lot of the energy of the family energy consumption. Many houses are older and built in a time when energy was cheap and when people coudl (would) live in much colder houses (and adapt their clothing)

Making a house into a passive house requires lookign at the following main factors:
- energy consumption
   - lighting
   - heating/cooling
   - cooking
   - entertainment
- energy loss
  - isolation
  - ventilation
- energy production
  - solar panels
     - warm water
     - electricity

In this blog message I like to show you an interesting method used by the vdm company of the Netherlands.

They "attack" the energy loss aspect of passive renovation by installing a ventilation heat exchanger and by construction a completly new outer shell of the building for isolation. Below some photographs of the proces an this is a link to a dutch (sorry) youtube movie.
