The EnEV (Energy Saving Regulation) 2009
Energy demand
Heating technology
Thermal insulation
……links Building Services Engineering with Systems Engineering.
A house is a complex system where one has
to consider both the techniques and the construction.
Improved thermal insulation and
efficient systems engineering are equal measures.
