Green Failures, Ctd

The unfolding record of disastrous Green policies almost defies belief.

Whenever the Green movement gets its hands on the levers of power, it drives nations deeper into trouble.

Ethanol – Fail.   Electric cars – Fail..  Carbon Trading – Fail.  Windmills – Fail.

And now home insulation – Fail.

Several German studies show that insulated homes consume more rather than less energy. These findings are especially significant because the German Federal Government plans to further tighten energy saving regulations.

Insulation does not always reduce heating energy demand in residential buildings. Its application can in fact increase the consumption of oil and gas. This is the result of a number of studies. The results raise the question whether the Federal Government’s green energy transition may fail in its objectives.

Particularly explosive is a recently rediscovered study by the IBP Institute for Building Physics  of the Fraunhofer Institute. Based on an detailed comparative analysis, scientists at the research institute in Stuttgart established in 1985 that, given average winter temperatures of minus four degrees Celsius, the use of insulating does not reduce heating energy consumption; compared to house with solid walls it rather pushes up energy consumption. 

“The expensive facade insulation is useless and even leads to rising heating costs,” says architect Konrad Fischer. The insulation critic from Hochstadt am Main has found the Fraunhofer paper again which was lost for decades.

According to the study, the fact that insulating materials do not meet the expectations placed upon them it is due to a simple physical law: massive walls can retain solar  warmth and radiate the heat into the interior spaces until late in the evening, even in winter. With insulated houses, however, this is not possible because of the thick plastic insulation covering the outer walls. As a result, “the interior is at no time supplied with heat”, the researchers at the Fraunhofer Institute already recognised 27 years ago.
