This tree view consists of the following branches, which can be expanded or collapsed:

• Library
  The library is used to enter the building types, structural elements (façades, party walls, partition walls, curtain walls, basement walls, roofs, cantilevers, floor slabs and floor screeds), doors, glazed openings (such as windows and skylights) and linear thermal bridges for the building.
• Zones
  For each zone, the rooms it comprises are defined by specifying the structural elements and linear thermal bridges. The terminal units of the HVAC system or systems serving the rooms in the zone are also defined.
• DHW systems
  The building's systems for the production of domestic hot water (DHW) are defined.
• HVAC systems
  The production and distribution subsystems of the building’s heating and/or cooling system(s) are defined.
• Own shadows
  This refers to building surfaces that are not part of the building envelope but which may cast shadows on facades and roofs, such as balcony slabs or parapets.
• Remote shadows
  The surfaces of remote obstacles that may cast shadows on the building are defined.
