| Abstract: | Based on the life cycle assessment of insulation material, a new economical optimum mathematics model of insulation thickness was presented. A simple algebraic formula for calculating economical thickness was obtained to minimize the total cost of external wall in life span. The model was used to calculate the economical insulntion thickness for a certain wall of Xuzhou, and the effect of different trpes of fuels on the economical insulation thickness was also taken into account. |
| Keywords: | life cycle assessment(LCA) building envelope economical insulation thickness |
