The purpose of the article is to introduce the condition of airtightness measurement market of large buildings in the Baltic states and in some European countries.
There are also considered national building norms of envelope airtightness and measured values.
Based on the measurement results of large buildings (more than 4,000 m3 volume according to ISO 9972-2015) the article assesses compliance of building norms of some countries with the actual building envelopes and the implementation of their controlling and stimulating functions.

Airtightness is the most important property of building envelopes to understand the ventilation. Airtightness refers to the flow measurement through the building envelope as a function of pressure across the building envelope. This relationship often fits to a power law, which is the most common way of expressing data. However, pressure homogeneity during airtightness tests can crop up, especially in large buildings.

CETE de Lyon gives support to French administration for thermal regulation definition and enforcement. They must therefore work on measurements in order to set appropriate requirements and give advice to professionals about building methods.
The absolute necessity of air renewal to maintain indoor air quality and thermal comfort in buildingsfaces the major issue of energy consumption reduction and optimisation in building sector. Manystudies carried out so far point out the performances improved thanks to the recourse to ventilationstrategies and control algorithms in the aim of optimising the energy consumption of air renewal, butvery few of them could assess the performances in the particular case of large buildings despite thepotential energy gains it represents considering the great volume and huge air flow rates induced.
