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 heat insulation has to be installed to diminish the thermal heat piercing onto the room. The research is concentrated to the thichness 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 saving energy domain.
