By right-clicking an object, it can be interacted with by common copy/paste-commands as well as scripts.

The table Windows shows all windows and skylights in the building, both inserted in zones and in faces (on a building body).

Name	The window name
Type	Window, Window (detailed) or SkyLight
Group	The zone group name. Shown as "n.a." (not applicable) for windows inserted into faces and having no adjacent zones
Zone	The zone in which the window is inserted.
Face	The face towards which the window faces or, for internal windows, the adjacent zone.
External or Internal	The face type of the window.
Sill height from ground	Distance from ground level to lowest point of the window.
Sill height from floor	Distance from zone floor level to lowest point of the window.
Azimuth	0 for windows faced to North, 90 to East, etc. Empty for horizontal windows
Slope	From 0 for floor to 180 for ceiling
Area	The window area including the frame. For skylights – the base area.
Glazing	The glass construction
g (SHGC)	The Solar heat gain coefficient of the glazing
T	The solar transmittance of the glazing
Glazing U	The U-value of the glazing
Frame fract	The fraction of the frame. Empty for skylights.
Frame U	The U-value of the frame. Empty for skylights.
Win total U	The overall U-value of the window. Empty for skylights.
Int Shading	The type of the integrated shading. For detailed windows available only if the window construction contains a shading layer
Control	Selection of control strategy for integrated shading device.
Schedule	Schedule for integrated shading, 1=completely drawn, 0=completely open
Ext shading	Choice of external window shading
Opening control	Selection of control strategy for window opening
Opening schedule	Schedule for degree of window opening, 0 = fully closed, 1 = fully open

The table Surfaces shows all walls, the floor and the ceiling of the zones in the building.

Name	The surface name
Group	The zone group name
Type	Roof/wall/floor, external or internal. In case of mixed external/internal the percent of mixture is shown
Area	The area of the inner surface of the wall, excluding windows, openings, and doors
Connected to	The list of the zones and faces on the other side of the wall
Azimuth	0 for walls faces to North, 90 to East, etc. Empty for horizontal surfaces
Slope	From 0 for floor to 180 for ceiling
Construction	Wall construction. Shown as "<mixed>" and non-editable for mixed internal/external walls. Constructions of any wall parts are not shown here.
U-value	The U-value of the construction at standard conditions . Shown as "<mixed>" for mixed internal/external walls.
Thickness	The total thickness of the construction. For mixed constructions, both values are shown: external / internal
Layer material	The material of the 1-st layer (the layers are ordered as defined in the wall construction). Empty for mixed constructions.
Layer thickness	The thickness of the 1-st layer. Empty for mixed constructions.
Layer material etc.	The material of the 2-nd layer etc.

The table Wall parts

An editable list of all wall parts in the building with similar columns to the "surfaces" table as described above.

The table Openings shows all oin the building, both inserted in zones and in faces (on a building body).

Name	The opening name
Type	Type of opening
Group	The opening group name. Shown as "n.a." (not applicable) for openings inserted into faces and having no adjacent zones
Zone	The zone in which the opening is inserted.
Face	The face towards which the opening faces or, for internal leaks, the adjacent zone.
External or internal	Type of the opening
Azimuth	0 for openings faced to North, 90 to East, etc. Empty for horizontal openings
Slope	From 0 for floor to 180 for ceiling
Area	The opening area.
Construction	The opening construction
U-value	The heat transfer coefficient (u-value, W/(m2*K))
Opening schedule	Schedule for degree of window opening, 0 = fully closed, 1 = fully open
Equivalent leak area	Leak area for closed internal doors
Inner surface	The name of the choosen inner surface with given properties
Outer surface	The name of the choosen outer surface with given properties
Annotations	Annotations of the opening

The table Leaks shows all leaks of the building inserted in zones.

Name	Name of the leak
Group	The leak group name.
Zone	The zone in which the leak is inserted.
Face	The face towards which the leak is inserted or, for internal leaks, the adjacent zone.
Azimuth	0 for leaks faced to North, 90 to East, etc. Empty for horizontal openings
Slope	From 0 for floor to 180 for ceiling
Inpar	0 if Leak area (ELA) is choosen and 1 if Powerlaw coef (CT) is choosen
ELA	Equivalent leak area, which is the opening area multiplied by the discharge coeffiecient, Cd, at 4 Pa pressure difference, dP
CT	Powerlaw coefficient (kg/(s*Pa^n)
N	Powerlaw exponent (massflow = CT * dP^N)
Annotations	Annotaions of the leak

The table Wall constructions shows all wall constructions available in the building. See the description of the columns of the Surfaces table

The table Materials shows all materials available in the building.

The table Facades and roof shows all roof parts and wall faces in the building model, along with their pressure coefficients. These coefficients are also available int the "Pressure coefficients" form in Global data.
