Iranian Researchers Develop System to Transmit Sunlight to Dark Parts in Houses

Amirkabir University of Technology (AUT) researchers succeeded in designing and producing a daylight transmission system with the ability to generate electricity in the building and reduce energy consumption, the AUT public relations department said in a report.

Ali Ramezani, an AUT graduate and project manager of "manufacturing a natural light transmission system in buildings with the possibility of using photovoltaic panels and batteries" said that daylighting device captures and transmits sunlight into a light panel inside a building.

“The purpose of this project is to design a system to transmit sunlight from the Southern, Northern and sides and roof of the buildings to their dark parts,” he said.

“In addition, in situations where there is no need for sunlight the system uses photovoltaic panels to produce electrical energy from the solar power and store it in the battery, and it is used for lighting during the night or during cloudy days,” the AUT researcher said.

Ramezani pointed out that the system has advantages over its imported rivals. “For example, the system makes it possible to store electricity and increase the length of light transmission,” he said.

“Implementation and installation of this project in existing and newly constructed buildings will reduce the air-conditioning cost in the buildings due to its shading feature on the Southward windows, and also because of generating electricity in the buildings,” he said.

“Also, the transmission of natural light to dark interior spaces reduces consumption of the lighting sector of buildings, especially for office use. It makes it possible to store electricity from the unused sunlight in the battery for later use,” he said.

According to the report, the AUT researcher further said that unlike the imported rivals that are only placed on the rooftops of the buildings, the Iran-made device can be put in various places in the building, therefore, more light is transmitted inside the building. In the meantime, it is possible to use the device on all floors, and allows more access to natural light.

According to the AUT public relations department, the AUT researcher Ramezani received an award from the Association of Electrical and Electronics Engineers (IEEE)-Iran branch for being the best undergraduate project of the year 2021.

Ramezani also received the best invention and innovation of the 6th national environmental conference in Iran.
