This project entitled “Solar Ventilition System” This study focuses on the use of low energy architectures through natural ventilation systems, building 'facade' interactions with the environment, indoor natural light, air conditioning, smart solar power systems for analysis and management of indoor energy. On the way to work, ventilate the supply of external air pumps into the building. The simplest mechanical version of this system is analogous to a fan mounted in a hole in the wall. It provides plenty of fresh air. But there is a significant drawback - in the cold winter supply of people.This can damage the health of the occupants and the condition of the premises. Therefore, this type of air supply system is commonly used only in warehouses and industrial premises. For effective air exchange in residential buildings, fresh air ventilation schemes have been developed with air heating.It is especially important in the winter and can include, in addition to heating, cleaning and moistening the incoming air mass. In addition, solar energy is a technology created to generate energy from sunlight. Sun energy has been used in many traditional technologies over the last several centuries. Examples of solar energy use include water heating, heating and cooking. In fact, the sun can also produce electricity through heating machines.With the latest technology, solar panels can generate daily electricity. Today, many homes, factories and industries are installing solar panels to generate electricity either for business or personal use.
