“…Modifications for Northern latitudes have led to integrated construction parts, minimized dimensions of gutters, the use of wide (>1.7 m) glass panels and white coated frames resulting in constructions with a limited light interception (Janssen and 't Hart, 2006). Within the limitations of current materials technology and international construction norms, further improvement of the construction transmission is expected to be only marginally (2%), e.g.…”

Efficient use of energy in greenhouses has been subject of research and development for decades. The final energy efficiency, e.g. the amount of energy used per unit of product, is determined by improvements in energy conversion, reductions in energy use for environmental control and the efficiency of crop production. The new European targets on reduction of CO 2 emission have resulted in a renewed interest in innovative technologies to improve energy efficiency in greenhouses designed for North-as well as South European regions. In this paper an overview of the recent developments is presented from both the Northwest European as well as the Mediterranean perspective. The developments range from new modified covering materials, innovative and energy conservative climate control equipment and plant response based control systems, to integrated energy efficient greenhouse designs.
