EN 13031-1:2001 Greenhouses — Design and construction — Part 1: Commercial production

Part 1 of this standard relates specifically to greenhouses used for the professional production of plants and crops where human occupancy is restricted to low levels of authorised personnel. 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), and to small domestic greenhouses.
This European Standard gives rules for structural design and construction of greenhouse structures for the professional production of plants and crops.
It is based on ENV 1991 "Eurocode 1: Basis of design and actions on structures" as regards the general principles and requirements for actions, mechanical resistance and stability, serviceability and durability considerations. For structural design considerations, it is similarly based on the relevant parts of ENV 1992 to ENV 1999 (Eurocodes 2 to 9).
Complementary information is provided to account for the particular requirements, functions and forms of commercial production greenhouses that distinguish them from ordinary buildings. Amongst the distinguishing functional requirements of greenhouses are the desire to optimise solar radiation transmission to create and maintain an optimal environment for the growth of plants and crops, and commonly, to support the weight of growing plants. These have implications on the form and structural design of commercial greenhouses.
Greenhouse designs, based on this European Standard providing specific information about load distributions, deformation criteria and tolerances, adapting rules of Structural Eurocodes, ENV 1991 to
ENV 1999, result in adequate structural safety. This is justified because in contrast to normal buildings, greenhouses have specific design working lives and human occupancy is restricted to low levels of authorised personnel.
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 the adopting European Standard.
Design criteria for the accessibility of the greenhouses, e.g. ascents, workways, walkways, or roof ladders may be part of national legislation.
