In the Mediterranean region, protected cultivation is considered as one of the most important agricultural enterprises. The availability of plastics and the low cost of frame materials contributed to the rapid development of protected cultivation. In Greece many types of greenhouse can be found, either constructed by specific industries or by farmers. The construction cost of the greenhouse plays an important role in the decision of the investor, as construction expenses constitute a very significant part of the greenhouse production costs which are very much determinant of the greenhouse economic effectiveness, notably in a world where available funds to agricultural investment are greatly limited. The Net Present Value (NPV) criterion was used to assess the economic effectiveness of a greenhouse structure. It has been proved that cheap greenhouse constructions are the most preferable, probably due to the Mediterranean weather conditions, and they can be recommended as the most appropriate structure for cultivating off-season vegetables.
