The ceiling system includes an air permeable suspended ceiling arranged below the structural ceiling, and a plenum space is formed between the suspended ceiling and the structural ceiling and a flooring space is formed between the flooring and the suspended ceiling. A plurality of partition wall sections is arranged in the plenum space extending between the structural ceiling and the suspended ceiling and forms a plurality of plenum modules distributed across the plenum space. Each plenum module includes equipment. The equipment of each plenum module includes a supply air device for delivery of supply air to the associated plenum module for pressurization thereof such that the supply air delivered to the plenum module is supplied to the flooring space through the air permeable suspended ceiling. ## Claims ### Claim 1 A building system comprising: a building space defined by a structural ceiling and a
