The natural ventilation systems of multi-story residential buildings are designed to meet the requirements for maximum air exchange. Their calculations under conditions significantly different from standard, usually do not carry out and therefore provide measures prevent their unstable operation. article presents results analysis system a two-room section ten-story building using mathematical m...

Estimating the temperature field of a building envelope could be time-consuming task. The use reduced-order method is then proposed: Proper Generalized Decomposition method. solution transient heat equation re-written as function its parameters: boundary conditions, initial condition, etc. To avoid tremendous number parameters, condition parameterized. This usually done by using Orthogonal to p...
