This study evaluates the performance of Single-Flow and Dual-Flow ventilation systems in a residential building situated in Strasbourg, characterized by high PM2.5 levels, permeable tightness, and strong wind conditions. The research examines indoor air quality by measuring CO2 and PM2.5 concentrations in bedrooms and compares the energy consumption of both systems across different cities.

The use of a sampling method for airtightness measurement of multifamily residential buildings - An example

Large buildings can not always be tested as a single pressure zone. In Europe, different approaches have been proposed concerning the choice of representative parts of the building (sampling method) and the compliance check in situations, when several parts of the building have to be tested separately. The preliminary Czech standard TNI 73 0330 defines a sampling method, as well as subsequent treatment of results and compliance check procedures for multifamily residential buildings. This contribution reports the results of a trial test of TNI 73 0330 method.
