A model was proposed to calculate the severity of fully developed fires in a multi room spreading scenario. The model is intended for use in fire resistance design. The model consists of a heat balance of rooms, network ventilation for mass flow rates through openings and heat conduction in enclosure walls. The model was compared with a full-scale experiment. Even though the verification is not perfect, the model could calculate the corridor temperature properly. Using the model, the effect of burning in adjacent rooms is examined for a simple two-room building and a realistic building with corridor and office rooms.
