The case study results show that overall energy consumption can be reduced by 1 ) increasing the concentrations of multi-functional crosslinkers in material composition , and 2 ) setting the shape programming and recovery temperatures as 10 to 15℃ above the material glass transition temperature without compromising the shape fixity and recovery ratios .
