Technical Building Regulations
For the rules regarding the implementation of solar thermal systems,
see the list of Building Regulations (LTB) [Germany] or local regula-
tions.
This combines the technical rules of all Federal States [Germany] for
the use of linear supported glazing (TRLV) issued by the Deutsches
Institut für Bautechnik (DIBT). This includes flat-plate and tube collec-
tors. These concern primarily the protection of pedestrian and traffic
areas against falling glass.
■ Glazing with an angle of inclination greater than 10° is described as
overhead glazing.
No additional safety measures to protect against falling glass parts
are required for flat-plate and tube collectors with an angle of incli-
nation greater than 10°.
■ Glazing with an angle of inclination of less than 10° is described as
vertical glazing
– The TRLV does not apply to vertical glazing with an upper edge
higher than max. 4 m above a traffic area.
No additional safety measures to protect against falling glass parts
are required for flat-plate and tube collectors with an angle of incli-
nation less than 10°.
– For vertical glazing with an upper edge higher than 4 m above a
traffic area, suitable measures must be taken to effectively prevent
glass from falling (e.g. through netting or trays below; see the fol-
lowing diagrams).

The yield can be optimised by rotating the individual tubes to 25°.
