Study on energy zero balance based lighting system in toilet zet lighting system using the energy harvesting technology implement to actual building

Research output: Contribution to journalArticlepeer-review

Abstract

In this research, the relationship between the possibility of zero balance of energy and the excretion were confirmed based on the data obtained from the demonstration experiment of ZET system. In the windowless the gents' toilet, found that the zero balance of energy could be achieved by reducing energy used for the behavior of needless excretion and wrong detection of lighting. The energy loss due to the lighting of unnecessary area for the excretion accounts for 2.8 to 15.7 %. In parametric study, one with the daylight window has surplus capacity from 1.65 to 3.65 times comparing to windowless one.
