This unification aims to specify and collect characteristics, executive procedures, calculation methods and test methods, for the correct drafting of greenhouse construction projects and for their good execution. In the design and calculation of greenhouses, procedures based on methods other than those suggested in this unification may be followed; it must also be proven that these other methods lead to safety coefficients no lower than those corresponding to the methods indicated in this unification.
