The results indicate that the moment amplification coefficient at the bottom section of columns in the ground floor should be compatible to that of the upper stories;
Through expounding the calculation process of the external wall, roofing, floor and door and window heat transmission coefficient, the article investigates the energy-savingc alculation.
