# Commission Implementing Decision (EU) 2017/302 of 15 February 2017 establishing best available techniques (BAT) conclusions, under Directive 2010/75/EU of the European Parliament and of the Council, for the intensive rearing of poultry or pigs (notified under document C(2017) 688) (Text with EEA relevance), Division BAT 8

Extent: E+W+S+N.I.

In order to use energy efficiently in a farm, BAT is to use a combination of the techniques given below.
A description of the techniques is given in Section 4.2.
Technique
Applicability
a
High efficiency heating/cooling and ventilation systems.
May not be applicable to existing plants.
b
Optimisation of heating/cooling and ventilation systems and management, especially where air cleaning systems are used.
Generally applicable.
c
Insulation of the walls, floors and/or ceilings of animal housing.
May not be applicable to plants using natural ventilation. Insulation may not be applicable to existing plants due to structural restrictions.
d
Use of energy-efficient lighting.
Generally applicable.
e
Use of heat exchangers. One of the following systems may be used:
1.. air-air;
2.. air-water;
3.. air-ground.
Air-ground heat exchangers are only applicable when there is available space due to the need for a large soil surface.
f
Use of heat pumps for heat recovery.
The applicability of heat pumps based on geothermal heat recovery is limited when using horizontal pipes due to the need for space availability.
g
Heat recovery with heated and cooled littered floor (combideck system).
Not applicable to pig plants.
Applicability depends on the possibility to install closed underground storage for the circulating water.
h
Apply natural ventilation.
Not applicable to plants with a centralised ventilation system.
In pig plants, this may not be applicable to:
housing systems with littered floors in warm climates;
housing systems without littered floors or without covered, insulated boxes (e.g. kennels) in cold climates.
In poultry plants, this may not be applicable:
during the initial stage of rearing, apart from duck production;
due to extreme climate conditions.
