dc.description.abstractIn multi-family buildings in Portugal essentially mixed ventilation systems are used. However, this system does not currently have a document that supports its design. The mixed ventilation system envisaged in the prNP 1037-5 considers two situations a) base flowrate given by passive devices which will allow the dwelling to be swept by flow rates due to wind action (e.g. horizontal ducts between compartments located on opposite facades), b) peak flowrate given by mechanical extraction placed in service compartments (kitchen and toilet facilities). In this paper, through a simulation using the CONTAM software and based on experimental data of air permeability of ventilation devices, an application of the design principles of the mixed ventilation systems idealized in prNP 1037-5 is performed. A sensitivity analysis is carried out by varying some of the most significant parameters in mixed ventilation systems, such as: geographical location, orientation and elevation of the dwellings; positioning of interior doors, closed or open. It involves the annual simulation of air flows using representative environmental conditions of the continental Portuguese climate (four cities), and the production of indoor pollutants (water vapor and CO2). Through this simulation we intend to conclude, for example, what is proper condition (opened or closed) of interior doors and the recommended air intake flows.pt_PT
