Pakis-Stem Blocks as Natural Heat Insulation Diminished Room Thermal in Surabaya

In the era of sustainable architecture where global warming is happen every time and day in many
countries, flat concrete rooftop heat insulation has to be installed to diminish the thermal heat piercing
onto the room. The research is concentrated to the thickness of Pakis-stem block layers that could obstruct
as low as possible of solar heat radiation piercing onto the room. By providing two flat concrete rooftop
models, the bare rooftop thermal and Pakis-stem blocks rooftop thermal performances could be monitored.
The outcome of the thermal performance of pakis stem blocks cover is crucial to lower the room
temperature. The lower heat room thermal coming from rooftop will lead to energy saving domain.
