“…It was concluded that storing of heat in a stone battery has positive effects (environmental, yield effects). There are many research papers concerning condensation drying of air in the literature (Han et al, 2015;Campen et al, 2002;Campen et al, 2003;Campen et al, 2009). The authors determined environmental effects, savings in heat consumption and suggested structural solutions for this system.…”

The paper, based on the materials of the Main Statistical Office, presents a present state of use of renewable energy sources in the Polish power industry. Moreover, based on the available data, the amount of energy used for roofed production was estimated (heat, electric energy). Additionally, the amount of emission to atmosphere of hazardous substances (sulphur oxides, lead oxides, carbon dioxide and carbon oxide, dust and benzo(a) piren) was determined. Based on the available literature, technical solutions, which are analysed in various scientific centres, which aim at decrease of fuel consumption, were presented. A detailed analysis focused on the possibility of substituting fossil fuel with another heat source, effectiveness of energy use, increase of insulation ability of the facility roof and modification of greenhouses structures. From among the available energy sources, problems and its possible use in horticultural production were presented. The following energy sources were analysed: geothermal energy, sun and wind energy, biomass, heat pump; co-generative system (triple co-generative). Also barriers and possibilities of use of own boiler house and heat from central heating grid as energy source were analysed.

During periods with relatively low radiation and moderate ambient temperatures, natural or forced ventilation is generally used to prevent (too) high humidity and this is related to a significant (5 to 20%) fraction of the energy consumption (Campen et al, 2003).…”

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.

“…The energy consumption and the CO 2 supply of a greenhouse depend on the greenhouse climate, the outside climate, the crop and the set-up of the greenhouse, including the energy supply system. For this study the validated dynamic simulation model KASPRO is used (Zwart, 1996;Campen, 2008). The used specific conditions for the greenhouse climate are common for Dutch growers.…”

For the pilot crop tomato, business concepts of low emission greenhouses for the midterm (10 year) have been designed. The study is carried out in cooperation with innovators in the horticultural sector, suppliers and extension services. The business concepts are evaluated for different indicators in the field of planet and compared to the current situation. The focus is on the reduction of energy consumption and CO 2 emission for the cultivation with and without supplementary lighting. The energy concepts differ in the way the heat and power are produced or supplied on business level. The results show that the energy concepts without supplementary lighting have a lower environmental impact and have a better energy efficiency than the energy concepts with lighting. The energy concepts without supplementary lighting show that simultaneous production of heat and power on business level and the delivery of electricity to the public grid is most favorable looking at the energy use and CO 2 emission on national level. Second best is the conditioned greenhouse. In this energy concept solar energy is collected in summertime, stored and re-used in wintertime. Conditioned greenhouses have also good perspectives in reducing the use and emission of pesticides.
