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
|
|
|
|
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
|
|
|
|
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.
|
Purpose conflict: no roof covered with greenery
|
|
|
|
Nevertheless, a few points of the otherwise very good Salzburg building furtherance support stand in the contradiction to own planning sighting. So the furtherance points for roof covered with greenery.
|
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
|
|
|
|
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
|
|
|
|
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
|
|
|
|
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
|
|
|
|
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
|
|
|
|
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.
