Identification and evaluation of effective risk factors of carbon Monoxide emissions in residential buildings in Isfahan province by integrating energy tracking methods and fuzzy logic

Tremendous growth of carbon monoxide poisoning statistics in recent years in Isfahan province shows the unfavorable condition of residential buildings for the use of thermal energy production system, which contradicts the objectives of national building regulations. The process of producing thermal energy using natural gas in buildings is subject to the energy contained in the system components. The unintended release or conversion of these energies into each other is due to the occurrence of emissions and increased carbon monoxide concentrations purposes. Thus, the present study was conducted in 1977 with the aim of identifying and managing effective risks using the ET & BA method which is a suitable tool for identifying errors by tracking the energies in it. Experts' verbal variables in the fuzzy environment were used to allocate the risks. The results showed that kinetic energy is one of the most important energies of the system and human errors during operation are the most risk factors. The inability of human senses to detect carbon monoxid emissions, is the most important stakes , the use of carbon monoxide detectors and alarms , extensive training for users through medias and implementation of 22 national building regulations were recommended as safeguards.
