Agricultural and Greenhouse Constructions (Theory)

The aim of the lesson is to present, to inform and to educate students on issues related to agricultural and greenhouse constructions. Particular emphasis is placed on understanding in phenomena taking place in a greenhouse. So, the students can analyze these phenomena and then be able to calculate the necessary equipment which they can achieve the proper conditions inside the greenhouse.


Upon successful completion of this lesson the student : • has demonstrated knowledge and understanding of issues relating to a) design, organizing and constructing agricultural buildings and agricultural products storage. b) technologies and techniques related to greenhouses. • has the knowledge to supervise agricultural building and greenhouse constructions. • has the ability to gather and to interpret relevant data in order to formulate judgments that include reflection on relevant issues with renewable energy. • Is able to notify ideas and solutions to problems related to renewable energy at both specialist and non-specialist audience. • has developed those skills to learn in order to continue his/her study in high level in a particular subject.
