Roof for a one family house

Planning for the roof, the deciding component, which makes a house an energy waster or energy producer. Electric power and warmth from the roof is a must.



Roof secure for the future
Roofs not producing no electric power an no heat and break down because a littile bit snowfall have nothing to do with a secure future.


Photovoltaic snow free by sliding Photovoltaic snow free by sliding
After the snow always slided down from the little bit descending roof to the windshield, it stands firm: The solution for a snow free photovoltaic.


Solar collector snow free Solar collector snow free
On the north side is like on all other houses about one half meter snow on the roof. But the snow can not perist on the large solar collector.


South side with sunny sight
Who gets the south side? Human or solar equipment? Against most rigid solar architecture, not the solar equipment but the human inhabitants.


Roof areas for the generation of energy
It does not matter to south, west, east or even a little bit towards north. Each roof surface, each partway sunny facade is urgent necessary for the generation of energy.





Snow shoveling on the roof Snow shoveling on the roof
A very dangerouse work on a snowy roof. For the workers, but also for the chief in case of an accident with an unsecured worker.


Solar-collector under snow Solar-collector under snow
Only a small upsurge in the snow shows, that on this roof of a garage is a solar collector. The failure: Below the collector is a tile roof.


Solar collector partial free from snow Solar collector partial free from snow
Only a half meter tiles below the solar collector prevent the sliding of the snw. Tin instead of tiles would help here.


Snow glides on a water film Snow glides on a water film
At the first time, I thought a prankster pushed all the snow from the roof to the windshield. Because it happened several times, I started to think about it.


Water film lets slide the snow Water film lets slide the snow
80 minutes after I was car driving, all the snow from the front of the roof had slid to the windshield. The warmth from the interior room has melted a thin layer of snow..


Snow turned over from the roof Snow turned over from the roof
Over the garbage container is a tin roof. The sun was sining on the left side. The heat had spread out to the right side and melted a thin layer of snow.






  Plan for house building - requirements specifications


From the first idea over the requirements specifications and how this develops to constructions plans. The development of my second plus energy house.

Ground plan for an one family house
Thoughts about the ground plan during the planning of our plus energy house. Size of the house, division and size of the rooms.


Cellar at house building
To much ground surface of the cellar for a usefull usage. New ideas to use the place below the house better. New demands which will be actual in the next decades.


Wall construction
From the simple mobile home wall construction up to a modern passive house. Overview over all wall constructions, we wrote in our technical magazine.
