Otherwise, the solar natural ventilation (NV) is expected to introduce the cooling requirement with power-saving of almost 10% and 15% saving of the annual power consumption required for fan when the operational and climatic conditions are more convenient .
A Comprehensive Guide to Eco-friendly Cooling Solutions Solar ventilation is a method of using solar energy to enhance the ventilation of a space, typically buildings or homes. This involves solar powered fans or vents that efficiently circulate air and regulate temperature.
The American Society of Heating, Refrigerating, and Air Conditioning Engineers (ASHRAE) defined natural ventilation (NV) as the introduction of outdoor air into the building due to the driving buoyancy forces of natural pressure or density differential.
In a building of 60 m high, with the total solar collector area of ten times of SC cross-section area, the air velocity reached 1.5 m/s at solar radiation higher than 800 W/m 2. The solar-induced ventilation system is convenient for high-rise buildings as suggested by Rao .
The solar-induced ventilation system is convenient for high-rise buildings as suggested by Rao . Natural ventilation deals with a broad range of Sustainable Development Goals (SDGs) in various aspects such as thermal comfort, climate action, good health and well-being, clean energy, as well as energy efficiency.
It is evident from extensive literature that a solar chimney is an excellent passive ventilation strategy used to enhance natural ventilation and provide thermal comfort. The effectiveness of the solar chimney on the improvement of ventilation rate and thermal regulation has been studied by various researchers numerically and experimentally.
