Daylighting transforming techniques: An approach to reduce energy consumption in residential buildings, the case of Amman in Jordan

Daylighting transforming techniques to basement levels to reduce energy used for lighting in buildings are investigated in this paper. A review of present technology is conducted to identify suitable techniques to transform daylighting to lower levels of the building. Glass pyramids (skylight) technique to transform daylighting from the top of the building through a shaft to lower levels is investigated. A typical multi-story residential building in Amman in Jordan is chosen to assess the efficiency of glass pyramids to transform daylighting through a deep shaft. Lux meter devise is used to measure daylighting in interior spaces in the levels of the building. Results indicate that daylighting can be increased when applying glass pyramids in the shaft. Thus, less energy is used in artificial lighting particularly in basement levels
