Based on the research of the energy embodied by building materials and transportation energy consumption,presents a simplified calculation method for construction energy consumption.

Analysed influences of opaque part,translucent part(glass window) in building envelope and different orientation to total energy consumption of building,got their influence rules to total energy consumption of building.

The definition,basic term,production technology,product attribute,energy saving and environment protective performance of Low-E glass were described in detail from explanation of heat emission,energy consumption of building,light pollution from glass.

Present situations of building energy consumption in Lvliang and questions existed;

Survey on building energy consumption with statistics theory;

Influence of Low-e glass on air conditioning load and building energy consumption;

Analysis on energy consumption and conservation of public buildings in hot summer and warm winter zone;

In order to understand the situation of residential energy consumption generally,a survey on the condition of energy consumption was made in seven cities from January to December,2006.

Although average person using energy in China is no more than half of that in the word, the gross of energy consumption has reached number two.

The building stock in Hong Kong has been expanding consistently in the past several decades to meet the needs of improving the living condition, which on the other hand results in a sharp increase of building energy consumption.

The BIN method,as one of simple steady state methods requires,reliable and detailed BIN data in order to calculate building energy consumption.
