In comparison to regular diesel fuel the quali-
ty biodiesel combustion causes in the engine
about 60% less of carbon dioxide emissions.
The biodiesel using in transport sector is also
not harmful to environment, because it takes
28days tobedecomposed in soil andonly few
days inwater.

Current building energy certificate (Process
chart) contains energy multicolor indicators
classified from to classG (themaximal energy
user-bottom) up to class A (the least energy
user-top) illustrating the logical process that
needs to be followed to improve the perfor-
mance of a definite building complementary
to national Energy Directive implementation
schemes.
Oneof thebiggest reasonsofheat losses inbu-
ildings is room ventilation. The space’ heating
isoneof thebiggest yearlycosts forhousekee-
ping, that'swhy thechoiceand thecontrol of a
heating system are important. From the very
beginning we have to decide about the kind of
fuel and the type of heating system regarding
the building characteristics or its isolation. In
case of the building’s façade surface renovati-
on the investment anyway will be reimbursed.
We also should keep inmind that the isolation
of the attic would be certainly reimbursed in
3 years.
According to the European statistical data,

INTERESTINGFACT!
Table oil without chemical treatment is not the same as biodiesel. The table oil has higher
viscosity and »acidity« in comparison to biodiesel, that is why it can not be used in usual
diesel engines. Averagehousekeepingwouldneedabout6,5haof land toproducebiodiesel
