Remarkable 3-in-1 Pakis-Stem Green Roofs for Saving Thermal Flat Rooftop
The green councils in the world are often promoting green buildings in terms of energy savings by mitigating the thermal load on buildings especially thermal rooftop into the room. Green roofs can be the most effective to lower roof thermal in tropical regions but complicated and costly
to build a perfect green roof even for a simple extensive green rooftop. This research looks for a remarkable growing medium for constructing green roof. Pakis-stem blocks can perform a 3 in 1 function: as a light-weight growing medium for green rooftops, an easytoform urban farming in private
buildings or residences, and an eco-friendly external roof insulation. After a deep measurement on the rooftop surface and room thermal behaviour, the pakis-stem green rooftop can reduce 16.4 °C of surface dry-bulk temperature and approximately 7 °C ambient room dry-bulk temperature
lower compared to conventional rooftops at noon. Furthermore, the surface temperature and ambient room air temperature difference between Pakis vegetative green rooftops and miana scrub green rooftop is approximately 7 °C and 3 °C respectively.
