Introduction
Part 1 of this document relates specifically to commercial production greenhouses used for the
professional production of plants (crops) where human occupancy is restricted to authorized
personnel, concerning low levels in number and duration. Other parts of this European standard are to
be prepared that relate to greenhouses where general access by the public is permitted (such as those
in garden centres or expositions).
This document gives specific rules and information, such as load distributions, deformation criteria and
limitations to tolerances, for structural design and construction of greenhouses to enable adequate
structural safety.
The structural design is based on EN 1990 and the relevant parts of EN 1991 to EN 1999 (Eurocodes 1
to 9) regarding the general principles and basic requirements for actions, mechanical resistance and
stability, serviceability and durability. National Application Documents (NAD) are considered.
Recommended values for structural design in this document are given in accordance with the
classification of greenhouses in EN 1990. This takes into account, that for commercial production
greenhouses the consequences and nature of failure and the importance for public safety are lower than
for normal buildings. The design working life is small. The potential economic loss is limited to the
owner and the impact on the environment is low.
Non-contradictory, complementary information is provided to account for the particular requirements,
functions and forms of commercial production greenhouses that distinguish them from ordinary
buildings. A distinguishing functional requirement is the optimization of solar radiation transmission to
create and maintain an optimal environment for the growth of plants (crops). This has implications on
the form and structural design of commercial greenhouses.
As rules and requirements of this standard may become adopted by other European standards, for
example the Structural Eurocodes or codes for Glass in Building – Design of glass panes, these will be
replaced by a reference to this document.
