Using Biomimetic Architectural Design Approach For Passive Natural Ventilation In Educational Buildings

Abstract

The air quality and fresh air in the internal spaces of the buildings are important for the users’ health. This component is especially important in intense user indoors such as offices, educational institutions, industrial buildings and hospitals. According to the World Health Organization (WHO), the number of patients in buildings that have not refreshed their interior ventilation system increases by 4.3 million people in the world per year. Passively designed elements such as manholes, windows, and electromechanical systems are used to improve building air ventilation. Active electro-mechanical air conditioning, ventilation systems are high costs and need more operating electricity spends. This study presents a passive ventilation system that consumes zero energy in building design. A university space that is used by intensive students was chosen as the case study. As a nature-inspired (biomimetic) approach, the termite nest ventilation system can be used from the current inputs in architectural design. External vents and air inlets were placed in classrooms 304 and 307 of the architectural department. Next, the use of air by the students and the supply of fresh air was simulated by software. The results showed that the recommended system has no open windows to prevent noise from outside and cold air in the winter. Also, it consumes no energy, has a low initial investment cost, and does not involve any operating costs. In conclusion, that zero energy architectural design is appropriate for educational buildings and other intense user buildings with functionality
