Air tightness of building structures and critical details
Vávra, Petr ; Tichomirov,, Vladimír (referee) ; Bečkovský, David (advisor)
In thesis is dealt with problematic of how the value of air permeability may be affected by properties for water vapour diffusion with regard to OSB material There were chosen two main brands of OSB at Czech trade market Two specimens of OSB with different thickness were chosen for each brand. As a first the specimens were tested for air tightness to work out a value of air permeability for each specimen. Afterwords, the testing was conducted for gaining properties of water vapour diffusion on each specimen. As a final assessment was analysed the impact of properties of water vapour diffusion on the air tightness for each specimen. The general meaning of gaining higher air tightness with higher water vapour resistance was proved . It was shown that with raising thickness is usually gotten higher value of water vapour diffusion resistance. However it could not mean getting high air tightness. The crucial parameter is the quality of the material for gaining higher resistance against water vapour diffusion as well as for higher airtightness.

Proposal of measures for reducing energy demands of food stores
Julinová, Patricie ; Vlach, František (referee) ; Bečkovský, David (advisor)
The master thesis deals with measures to reduce energy performance of grocery store building. Model of the grocery store is evaluated according to a recommended energy values specified by Czech standards and according to the real values of the actual consumption. These values are compared. Final building analysis for a proposal measures to reduce energy consumption is based on the invoices of the real consumption and on the experimental assignments. Experimental measurements are the Blower door test of the tightness of the building envelope, the measures with the thermovision camera and the measuring of the illumination intensity. The most efficient proposal is extended to the whole model network of the food shops in the Czech Republic.
