Information
Detailed model of a single-zone with Ubat and variable inertia
This model allows the representation of Individual House / Collective Housing / Tertiary Building in single zone. The modelling is detailed, walls and windows are distinguished according to their orientation.
The loss level represented by Ubat is adjustable.
Hypothesis and equations
Geometry
Model of a parallelepiped 0D-1D square section single-zone. The building height depends on the number of levels (NbNiveau), on total air volume (Vair) and on the living area (HS). The building is oriented in the four cardinal points. Glazing are defined on every façade.
Building typology
Building typologies (materials and layers thicknesses) are considered in detail.
Inertia is adjustable by choosing the constructive mode via the wall type. The inertia due to inner walls, outside floors, is neglected.
The choice of walls parameters (paraParoiV...) describing building typologies and of glazing parameters allows to compute a reference Ubat. The Ubat of the building is then adjusted to the parameter Ubat using insulations of external walls thicknesses. Floor insulation is not considered in this adjustment.
Physics
The coefficient B imposes boundary conditions on the low floor outer face. The entire solar flux transmitted through the glazing is absorbed on floor(s) surface. The ceiling / roof is subjected to SW/LW radiations as well as vertical outer walls.
Bibliography
Refer to BuildSysPro walls and glazings modelling assumptions.
Instructions for use
The solar fluxes different ports are connected with a FLUXzone model. The outdoor temperature port must be connected to a weather block.
Known limits / Use precautions
Depending on the chosen building typology and the type of glazing, Ubat can be chosen anyhow. It must necessarily be framed. An error message occurs when the selected Ubat is out of this range.
