Abstract
Recycling of building materials with good insulation properties if you can
reduce indoor air-conditioning energy consumption. But, how is it effective the
insulation? This study to investigate energy saving efficiency for recycling of
building materials. Wish to contribute to the promotion of renewable and application
of insulation tiles.This study will these materials’s U-value into a computer simulation
of HVAC system to analyze its’ energy consumption patterns. From this study we
have conclusions as follows：1. Recycling of rubber have the best energy saving
efficiency in the insulation brick(save 2.5% of electricity). 2. Recycling of light tiles
is better general tile (save 2.5% of electricity).
