This research focuses on Light Metal Structure and compares different temperature control designs and methods in order to establish a simple evaluation system for public use. The heat-reducing methods compared in this study are Insulation material to cool and buoyancy ventilation to cool. After the acquisition of a series of on-site statistics, related theories were applied to evaluate their efficacy of heat-reduction. The analytical results in heat-reduction and thermal environment of Light Metal Structure shows that variables for preliminary system has a better heat-reduction rate on higher buildings, and that heat-reduction rate is influenced by Building aperture area. The results of this study lowers the Professional threshold for common people in evaluating Light Metal Structure’s heat-reduction systems. Numerical analyses were applied on case studies to evaluate the Building Materials’s influence on buoyancy ventilation, and a chart was hence made to weigh all variables for preliminary reference in heat reduction of a building. This study suggests that, when reducing heat with buoyancy ventilation, besides controlling each parameter and customizing building for heat-reduction, the evaluation chart in this study can also be used in selecting an appropriate heat-reduction system. It should also be noted that, when reducing heat with buoyancy ventilation, after complying with the theoretical formula of buoyancy ventilation Theory, the ventilation passage design should be checked for clearance.
