Nevertheless, greenhouses are used to minimize the negative effects of those environmental constraints. As winter approaches, the need for heating increases. The energy consumed to heat a greenhouse can be as high as 80% of the total energy required to run a greenhouse business. As energy costs are increasing, many greenhouse operators are re-evaluating energy consumption and savings strategies. In most cases, updating older heating systems to more efficient units in addition to the use of double layer glazing, insulation materials, and energy curtains significantly reduces fuel . Plant Factory: An Indoor Vertical Farming System for Efficient Quality Food Production. provides information on a field that is helping to offset the threats that unusual weather and shortages of land and natural resources bring to the food supply.. As alternative options are needed to ensure adequate and efficient production of food, this book represents the only available resource to take a.

The energy saving effect of screens might be divided into two components where the screen acts as a physical barrier to mass transport and as a blockage to radiation, respectively. Modern greenhouses exhibit a low natural air exchange rate and the long wave radiation properties of the screen material become important in energy saving.

EfficiEncy improvEmEnts cut EnErgy costs and boost production Operating a commercial greenhouse or nursery is a delicate balancing act, with the need to tightly control temperature, humidity, ventilation and light.

Optimizing such variables can be highly energy intensive and take an increasing bite out of profits. Energy for greenhouse heating is required both in summer and winter in Northern Europe. if the plant and the greenhouses lie close together. The technical problems of low temperatue heating systems are solved more or less.
