The window is one of the most important aspects a building. It aims to obtain good lighting and meet requirements for Indoor Air Quality. A restroom place where surfaces are wet, it causes relative humidity become high. As result, must be considered in this space. men’s toilet on second floor Bina Nusantara University campus Malang subject research. Interviews with building operators, cleaners firsthand surveys location were also undertaken. author used results interviews help specify ventilation system. utilizes lux meter measure layout. According findings, uses mechanical form an exhaust fan. On other hand, area employs downlights that standards terms brightness color temperature selection artificial In current situation, there shortage energy efficiency. study offers method preserving electrical energy. This Arduino Mega several sensors automate operation these devices.
