Extends from ZoneSlab (Model of parallelepiped zone on unglazed slab-on-grade floor, in pure thermal modelling).
Information
Model of parallelepiped glazed zone on slab-on-grade floor, in pure thermal modelling
Hypothesis and equations
Parallelepiped single-zone glazed building on slab-on-grade floor model, to be connected to a boundary conditions model (left thermal port) and a left realOutput for solar fluxes. By default walls are oriented in the four cardinal points; the orientation modification is represented by the parameter beta. The right thermal port is connected to the inner volume (heat capacity). Floor and ceiling are subject to outside temperatures which are weighted by a coefficient b.
This model inherits from ZoneCrawlSpaceGlazedInternalPartitions and superimposes on it the glazings.

Instructions for use
This single zone building model is to be connected to a weather boundary conditions model on the left (outside temperature, sunlight-related data). The right thermal port is connected to the inner volume (heat capacity) and can, if desired, be connected to any model using a thermal port (internal heat gains...).
The walls parameterization is done via the parameter caracParoi, however it still can be done layer by layer without creating any type of wall.
- Click on the small arrow of caracParoi + Edit
- Fill in the fields on the number of layers, their thickness, the mesh. The parameter positionIsolant is optional
- For the mat parameter, click on the small arrow + Edit array, match the number of boxes in a column to the number of materials layer in the window that is displayed, then, in each box, right-click + Insert function call and browse the library to specify the path of the desired material (in
Utilities.Data.Solids)
Known limits / Use precautions
To consider walls radiation in long wavelength (LWR), exchange coefficients h must be global exchange coefficients.
Glazings transmit solar fluxes to the floor.
