Architecture is a huge sector of energy consumption. According to some relevant statistics, it consumes nearly 40% of total energies in all industries globally. In recent decades, the whole world is in the presence of a severe energy crisis, the conservation amount of fossil resources are decreasing continuously. Energy saving has been a compelling task for all human beings. Among all energies consumed by buildings, the buildings that have existed for a long term is a crucial section. Most of them were constructed in or before the middle of last century without the consideration of energy efficiency design. And new buildings have a replacement ratio of 1% to 3% annually. Reducing the total energy loads caused by buildings, the existing ones will be a key. It is extremely necessary to analyse the existing buildings to discover their weakness in energy efficiency for finding suitable measures to address the problems.
