Conventionally, a boundary line between the interior zone and the perimeter zone is provided, for example, every 1 m from the outer wall surface in the winter season to cope with the assumption that a cooling load is generated in the interior zone and a heating load is generated in the perimeter zone. It is common to provide an air conditioning system, but due to external weather conditions such as cold and warm, solar radiation, uneven distribution of office equipment heat, actual conditions of personnel and lighting, etc., the cooling load and heating load may not always be as expected. It is a fact. Depending on the space, it may be too hot or too cold.
