  "text": "In order to use energy efficiently in a farm, BAT is to use a combination of the techniques given below.\nA description of the techniques is given in Section 4.2.\nTechnique\nApplicability\na\nHigh efficiency heating/cooling and ventilation systems.\nMay not be applicable to existing plants.\nb\nOptimisation of heating/cooling and ventilation systems and management, especially where air cleaning systems are used.\nGenerally applicable.\nc\nInsulation of the walls, floors and/or ceilings of animal housing.\nMay not be applicable to plants using natural ventilation. Insulation may not be applicable to existing plants due to structural restrictions.\nd\nUse of energy-efficient lighting.\nGenerally applicable.\ne\nUse of heat exchangers. One of the following systems may be used:\n1.. air-air;\n2.. air-water;\n3.. air-ground.\nAir-ground heat exchangers are only applicable when there is available space due to the need for a large soil surface.\nf\nUse of heat pumps for heat recovery.\nThe applicability of heat pumps based on geothermal heat recovery is limited when using horizontal pipes due to the need for space availability.\ng\nHeat recovery with heated and cooled littered floor (combideck system).\nNot applicable to pig plants.\nApplicability depends on the possibility to install closed underground storage for the circulating water.\nh\nApply natural ventilation.\nNot applicable to plants with a centralised ventilation system.\nIn pig plants, this may not be applicable to:\nhousing systems with littered floors in warm climates;\nhousing systems without littered floors or without covered, insulated boxes (e.g. kennels) in cold climates.\nIn poultry plants, this may not be applicable:\nduring the initial stage of rearing, apart from duck production;\ndue to extreme climate conditions.",
