Malaysia relies on non-renewable sources like fossil fuel and coal by 90%. The energy industry itself contributes about 77% of total carbon dioxide gas emission in 2011. Due to that, the government of Malaysia published Green Technology Master Plan Malaysia 2016–2030 to help reducing the carbon dioxide gas emission. This shows how serious the problem caused by electricity generation. Thus, the end user is encouraged to reduce electricity usage by switching to sustainable product. Turbine ventilator and tubular skylight has been invented a long time ago, which offers natural ventilation and natural lighting respectively. The usage of these devices could reduce the dependency on electricity use especially for a windowless space or a space located far from the window. Both of these devices require an area as they are commonly placed on the roof. This research aims to overcome these problems by designing a device that can provide natural lighting and ventilation without the usage of electricity. The device is called PhotoVenti which represents the photon and ventilator. The performance of this product is analyzed through experimentation on a test house located in Panchor, Muar. The average of illuminance obtained from the experiment are 232 lx and 208 lx and the average of indoor temperature obtained are 27.6 and 28.3 ℃. MS 1525 and MS 2680 and Industry Code of Practice of Indoor Air Quality 2010 to are used to describe its conformity under Malaysian climate.
