low energy buildings

A voluntary certification for very low energy buildings has been implemented in 2013 in France, which requires among other the ventilation systems to be controlled by an independent technician. To ensure the expertise of these technicians, a certification scheme has been implemented for the airtightness measurement of ductwork. This certification will soon be required for the ventilation system controls.

There is an increasing demand for energy efficient and environment-friendly buildings with a high  thermal comfort. On the other hand, the Kyoto protocol binds the developed countries to reduce the emission of greenhouse gases at least by 5% by 2008-2012.

In 2005, the Executive Committee of the International Energy Agency’s (IEA) Energy Conservation in Buildings and Community Systems (ECBCS) program approved the start of a new four-year research project on building commissioning. Annex 47, on “Cost-Effecti

With the growth of living standards, there is an increasing demand for the cooling of living space. Rational energy use demands the use of alternative ways of cooling because the energy consumption of compressor cooling is high. In this article a new cheap and efficient paperboard compact heat exchanger and indirect evaporative cooling are presented.
