We are working on a office building in which there is an openspace. The outside openings largely cover 4% of the total floor area. A small part of the open space area falls outside the distance of 7.6 m from the openings. For this part of space I have to provide an engineered ventilation dimensioned only on the area that falls beyond 7.6m? Or the engineered ventilation system shall be sized on the total openspace area?
