Method and system for controlling environmental conditions of different entities

A controlling system for adjusting environmental conditions of at least first and second entities, characterized in that, each of the entities has desired environmental conditions for at least two different states, and that the system comprises

• a) first equipments for adjusting the environmental condition of said first entity, and second equipments for adjusting the environmental condition of said second entity, where the adjusting is based on controlling parameters,
• b) first controlling means for controlling the function of said first equipments, and second controlling means for controlling the function of said second equipments,
• c) first measuring means for measuring environmental condition in said first entity and signalling it to the first controlling means, and second measuring means for measuring environmental condition in said second entity and signalling it to the second controlling means, and
• wherein
• d) said first and second controlling means are adapted to provide said controlling parameters to said first and second equipments so that at least one parameter used for controlling the environmental condition of the first entity depends on at least one measured environmental condition parameter of the second entity, and that at least one parameter used for controlling the environmental condition of the second entity depends on at least one measured environmental condition parameter of the first entity, where said first entity is different that said second entity.
