Material layer input is available for floors, roofs, walls, panels and doors.
It is important to note that walls, panels, and doors are defined by means of an inside and outside. Floors and roofs are defined based on an upper and lower side, irrespective of whether the inside or outside is concerned.

If there
is a thermally active construction required for floor heating, floor cooling,
radiant ceiling, cooling ceiling, wall heating or concrete core activation,
choose the layer in which this delivery system is incorporated.

The plenum indicates whether the material layer
is part of the plenum. A plenum is the space in between the "true" ceiling and a
lowered ceiling, but also in between the "true" floor and an elevated floor as
is typically found in computer rooms. This space is included in the net volume
of the room as the inside air is able to circulate in the plenum. It is only
possible to assign a plenum in a floor or ceiling. The size of the plenum is
determined from the lower side of the plenum up to the lower side of the floor
above.

In the ISSO 51, ISSO 53 and ISSO 57 calculation methods, the average plenum height is not taken into account as it is assumed that regular houses do not contain a plenum. This is the case even when the geometry is defined with centre point dimensions, since the software uses the internal dimensions for the calculations. The software computes the room dimensions using the average wall thickness and average floor thickness which have been specified.

In the calculation of the ventilation volumes, the inner dimensions are considered, i.e. excluding the plenum. |
