FAO/CNRE WORKING GROUP ON SOLAR ENERGY FOR HEATING OF GREENHOUSES

Dr. I. Segal
The FAO/CNRE Working Group on Solar Energy for Heating greenhouses was established at the first solar energy network consultations in Israel in October 1983.

It main goals were to promote:

  1. Systematic exchange of information.
  2. Joint research activities.
  3. Establishment of recommendations for research and development and applications.
  4. Transfer of know-how to developing countries.

The working group, headed by Prof. Von Zabeltitz completed the following activities:

  1. Completion of a state-of-the-art study "Greenhouse Heating with Solar Energy" describing about 50 projects in 15 countries.
  2. Organization of three workshops (in Cyprus, Greece and Turkey) to discuss the state-of-the-art study.
  3. Starting a joint experiment on passive storage of solar energy in greenhouses utilizing thin wall transparent polyethylene tubes.
  4. Cooperation with other groups on preparation of a guideline bulletin regarding conservation and renewable energies in greenhouses.

The main conclusions drawn from the first four years of activity:

  1. Utilization of solar energy for greenhouse heating in view of the low fuel prices is a difficult technical and economical task. Only the most simple systems are applicable and cost effective.
  2. Cooperation with other groups dealing with energy conservation and other renewable sources is necessary.
  3. Combined horticultural and engineering research is most important to optimize production in greenhouses in the future.
