Electric power, heat and climate regulation

Big towns have a some degree Celsius more warm climate than the green surroundings. This has not to be like this, however a mad energy wastefulness costing us much money.

  Double energy wastefullness

In the summer time, sun heats up the roofs of the houses. When the buildings have in a big town a big part of the total surface, this means a general heat up of the whole town area. Every weekend, many people flee from the town area. Big traffic jams Sunday in the evening, when all this people return in the unloved town.

The energy from the warm roofs is wasted. The inhabitants driven out by the unpleasant urban climate in endless rows of vehicles driven by ICE combustion engines.

On the other hand in winter, all the houses are heated by burning fossile fuel. An insanity of the crude oil age.

  Cool roofs, store heat, climate regulation

The underground below a town from 20 to 100m depth as a gigantic season storage. In summer the heat from the roofs is stored in the underground. The underground becomes warmed up by some degree Celsius. In winter, the heat stored in summer is used to warm the houses by heat pumps.

Good insulated houses with heat recovery at air exchange do not need so much heat like taken from the roofs in summer to regulate the climate. What to do with this waste heat? Less salt to make in winter the streets free from snow and ice, because it's possible to warm the streets? Glas covered shopping streets in winter with 10 degree Celsius?

Photovoltaic - Electric power direct from light Photovoltaic - Electric power direct from light
Even a far north situated industrial nation like Germany could produce a big part of the needed energy by the roofs of the houses. Photovoltaic has much potential.

Photovoltaic and heat combined Photovoltaic and heat combined
Cogeneration of electric power and heat from one modul. Optimal utilization of roofs by combined production of electric power and heat on the same area.

  Future urban development

New technical development brings new planning targets for municipal politicians and new design possibilities for architects.

Energy turning point full in progress
Application for application will be the word cheap oil and expensive solar energy turned in the opposite. Cheap solar energ and expensive oil will be the oppinion of the masses.

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.

End of the compressed urban planing
We live where we yield the solar energy. The required area is regulated by the energy demand. Tendency against compression and pro generous surface usage.

Urban planing: Turn of the parameters
Until now, more compression was the philosophy, but a turn around of many parameters goes in the opposit direction in favor for the people.
