Fire and smoke control in naturally ventilated buildings

Though there is a developing interest in achieving low-energy, naturally ventilated, non-domestic buildings in order to achieve reductions in carbon dioxide emissions, those two case studies demonstrate that local authority Building Control Departments, fire authorities, insurers are reluctant finding some uncertainties about compliance of natural ventilation with the current fire regulations and codes. So the current regulatory system impacts negatively in the use of natural ventilation and prevents innovation.
