INFILTRATION IN A COMPLEX BUILDING

The air infiltration through building envelope mainly depends on the doors and windows tightness considered by means of corresponding effective leakage areas pressure difference between exterior interior. Although standards provide simple methods to estimate parameters that control movement, significant differences in volumetric flow fresh are observed standardized most accurate traditional methods. Our aim is evaluate a two-storey with large central atrium during typical day January considering all relevant parameters. analytical result incorporated numerical simulation EnergyPlus determine internal temperature evolution sensitive intake. Simulation results compared in-situ measurements. It found rate calculated from procedure only enables be reproduced substantial adjustment design rate. methodology developed useful calculate buildings under actual use conditions assess when measurements not available.
