The decree requires the classification of new construction with a label that informs buyers of how efficiently the building. It is that every building has a label with your energy rating (A, corresponding to the buildings more efficient, to G, less efficient buildings) and the inclusion of estimated energy consumption and emissions associated CO2.
However appliances undergo a test in a laboratory, while the buildings are much more complex systems whose operation can not test or estimate so easily subjected to conditions and usage habits much more variable. Therefore, implementing such a system is not possible if it is not making major simplifications. In addition, the Read the rest of this entry »
