Quality evaluation for scale-up of moss (Sphagnum sp.) rooftop greening panel using Taguchi method

Rooftop greening panel is a moss plant (Sphagnum sp.) grown, overlaid in a panel and installed in a narrow open space on a rooftop building. As the final step prior to the full-scale agro-industry, scaling-up the moss panel is required and must be designed in consideration to the quality evaluation. The research objectives are: 1) to design a scale-up for moss (Sphagnum sp.) rooftop greening panel by means of Taguchi method; 2) to evaluate the quality for scaling-up the moss panel in rooftop building; 3) to identify the design factors involved in scale-up process of moss panel. The result then showed the photosynthesis rate, CO2 absorption and L*a*b color with the quality robustness in rooftop building.
