Rc-value and mass

Rc and Mass input is available for floors, roofs, walls, panels and doors.

Thermally Active

HL BS EPG
This box indicates which of the layers is thermally active. This layer is then coupled to the selected HVAC template; provided an emissive device which makes use of the thermally active layer has been assigned, such as floor heating, floor cooling, a heated ceiling, a cooled ceiling, wall heating, or concrete core activation. It is only possible to have a thermally active layer inside a floor, roof or wall.

Rc value

HL BS CL EPG
This is the overall heat resistance of the construction. A well-insulated structure has a high Rc-value.

Mass

HL CL BS
The mass of the construction per square metre.

•      Light (100 kg / m²)

•      Medium (200 kg / m²)

•      Heavy (500 kg / m²)

Thickness

HL BS CL EPG
The value of thickness represents the total thickness of the construction. This value is important as it is used by the software to calculate the net floor surface area and the net volume.

Plenum thickness

HL BS CL EPG
This represents the thickness of the wall corresponding to the plenum. The plenum thickness is only required for floors and roofs. 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 applied in computer rooms. This room is included in the net volume of the room as the inside air is able to get into 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.
