The present document is the result of a study led by the Fire Research and Innovation Centre (FRIC), aiming to help enhance the fire safety of new technologies in buildings. Accordingly, the study firstly evaluates the technology of Vehicle-to-Grid (V2G) to identify its related fire risks for buildings and to propose fire safety measures that allow mitigating the identified risks. V2G is an alternative technology for enhanced energy storage and the use of renewable energy in buildings. This technology uses the batteries of Electric Vehicles (EVs) to store energy and then returns an optimal amount of the stored energy to the power grid when needed. The present document evaluates the fire hazards of EV batteries integrated with V2G technology and provides an overview of the existing regulations as well as developing standards in this area. Secondly, the study evaluates the technology of smart ventilation systems, i.e., systems that employ sensors to improve indoor ventilation quality and its efficiency in terms of energy consumption. The present document evaluates the influence of such systems on fire safety in buildings, especially from the perspective of their interaction with fire suppression systems.
