Impact of air tightness on the evaluation of building energy performance in Lithuania
In order to fulfil the European Energy Performance of Buildings Directive (EPBD)
requirements for the reduction of energy consumption, European national requirements
have been created for building envelope thermal properties and calculation methodology to
determine if building energy efficiency is created. This is however not true in all
methodologies. The necessity of building air tightness appears only for new A class
buildings, and there are no requirements for air tightness for other building classes …
