The Fire Navigator: smoke and flame sensors in smart buildings

The Fire Protection Engineering magazine has recently published our article reporting exciting research on the theme of smart buildings and fire protection. In this work, sponsored by Chief Donald J. Burns Memorial Research Grant, my student Nahom and I developed an algorithm that uses data arriving from building sensors to detect and map an ongoing fire. The algorithm, called the Fire Navigator, then provides forecasts of future smoke and flame spread within the building, allowing to see where and how the fire would propagate if not stopped before hand.

We envision that the forecasting of fire dynamics in buildings will lead to a paradigm shift in the response to fire emergencies, providing the fire service with essential information about smoke propagation and flame spread ahead of time (i.e. minutes before it happens). Disposing of information on fire events before they actually happen would have a positive effect on the fire service efficiency and safety, therefore saving human lives and mitigating property losses and environmental damage. Smart buildings anticipate the occupants’ needs with the help of various sensors. Control of heating and air conditioning, energy consumption and lighting are now common examples of how sensors allow control over key aspects of the built environment. We want to extend this to fire safety engineering and enhanced fire fighting. Already existing smoke and heat sensors, as well as sprinklers, generate data that has yet to be harnessed and used in smart buildings. This is what our article proposes and shows how to do it.

Our work is based on combining new and old ideas. The new ideas are the use of a very quick fire model based on cellular automata theory, and the integration of  the whole system into building information models (BIM). You can read the full article at the SFPE website:
