“…Delayed plant growth is then compensated for by higher temperature under conditions requiring little or no heat demand, such as when the wind speed is low, the outside temperature is high or solar radiation is high (Bailey, 1985;Körner and Van Straten, 2008). The possibility to exploit such temperature integration systems has been published for several ornamental plants and vegetable crops, such as roses (Buwalda et al, 1999), chrysanthemum (Körner and Challa, 2004), cucumber (Slack and Hand, 1983), sweet pepper (Bakker and van Uffelen, 1988) and tomato (De Koning, 1990). These strategies, which are based on a combination of models and empirical knowledge, usually use fixed time periods for achieving a certain average temperature independent of all other micrometeorological variables.…”

“…The presented microclimate model has the potential for being generic. A simulation case study showed that using this model to predict crop microclimate is a promising alternative to greenhouse air temperature control and may be used for model-based dynamic control regimes (Aaslyng et al, 1999;Bailey, 1985;Bailey and Seginer, 1989;Buwalda et al, 1999;Kö rner and Challa, 2003a;Seginer et al, 1994) or for the concept of optimal greenhouse climate control (Gal et al, 1984). Because 10% energy is saved by a 1°C lower greenhouse temperature (Tantau, 1998), heating demand and therefore energy consumption can strongly decrease when using this microclimate model for crop temperature control.…”

“…Energysaving is highest during winter and 12% energy saving was attained during January under Danish climate conditions. During the last 20 years, several dynamic temperature regimes were designed for greenhouse energy-saving (e.g., Aaslyng et al, 1999;Bailey, 1985;Bailey and Seginer, 1989;Buwalda et al, 1999;Körner and Challa, 2003a;Seginer et al, 1994). In the early 1990s, a complete dynamic climate control concept was first developed (Aaslyng et al, 2003) and constantly further developed since then.…”

Greenhouse energy-saving and biocide reduction can be achieved through dynamic greenhouse climate control with computerized model-based regimes. This can be optimized when next to greenhouse macroclimate (i.e., the aerial environment) also, the crop microclimate is predicted. The aim of this article was to design and apply a simple deterministic microclimate model for dynamic greenhouse climate control concepts. The model calculates crop temperature and latent heat of evaporation in different vertical levels of a dense canopy of potted plants. The model was validated with data attained from experiments on dynamic or nondynamic (regular) controlled greenhouse cultivation. Crop temperature was with a 95% confidence interval of 2 °C or 2.4 °C for sunlit or shaded leaves, respectively, accurately predicted in a simple greenhouse with predefined climate set points. With a more dynamic greenhouse control also including assimilation lighting and screens, the prediction quality decreased but still had a 95% confidence interval of crop temperature prediction of 3.8 °C for sunlit leaves. Simulations showed that controlling greenhouse temperature according to the predicted crop temperature rather than according to the air temperature can save energy. Energy-saving is highest during winter and 12% energy saving was attained during January under Danish climate conditions.

“…The energy savings depend on the crop and the magnitude of temperature fluctuations allowed. The range of energy savings with TI, according to experiments and simulations, is 5-15% (Buwalda et al 1999;Körner and Challa, 2003;Elings et al 2005), with few effects on production.…”

Mid 2011 the proposal "Towards a sustainable and productive EU organic greenhouse horticulture", in short, BioGreenhouse, was submitted.At the end of 2011 COST approved this proposal as COST Action FA1105 (see http://www.cost.eu/COST_ Actions/fa/FA1105 and www.biogreenhouse.org), which builds a network of experts working in the field of organic protected horticulture and aims to develop and to disseminate through coordinated international efforts, knowledge for new and improved production strategies, methods and technologies to support sustainable and productive organic greenhouse/protected horticulture in the EU. In total 27 participating COST countries and two COST Neighbouring countries took part in the Action.This Action offered the framework and funds for experts of the participating countries to meet and to work together in Working Groups concerning the objectives of the Action. The objectives related to climate and energy management where: an inventory of the use of fossil energy in the present organic greenhouse horticulture;to develop guidelines for the reduction of the use of primary energy in different regions; to join available information about reduction of energy use and improvement of productivity; and to evaluate the feasibility of substitutes of fossil energy.Nine experts from different regions worked together on this topic. They have addressed their task with commitment, by reviewing the regulations as they exist on energy use for heating and humidity control in the different regions in Europe; presenting strategies for reduction of energy requirement and to increase the productivity of energy; by reviewing the indirect use of energy and the options for replacement of fossil energy by renewable energy.Together they realised this booklet:"Sensible use of primary energy in organic greenhouse production" I believe this booklet will prove a unique source of information for all people and institutions involved in research in organic protected horticulture; for researchers, students, teachers, consultants and suppliers. This booklet could also serve also a starting point for developing strategies for a climate-neutral organic greenhouse ho...
