In the north cold cities of our country,lots of buildings have been reconstructed for energy conservation.

The design of residential building in severe cold area;

The comprehensive roadbed construction technology of special railway line for passenger transportation in severe cold area

According to the research on the feature of building energy consumption in severe cold area, we divide the building energy consumption into heating energy consumption and building power consumption.

Design and construction of earth dam overflow face concrete strengthening in cold area;

Application of stepped reinforcement gabion energy dissipater in cold area;

Design research of the exterior surrounding structure of the country energy saving residence in cold area

Energy conservation design of village residence in severe cold regions;

Energy-efficient design for power plant buildings in severe cold region

Energy saving and daylighting design of windows is the residential buildings in the high latitude and severe cold region——tanking Wulumuqi region for example

Measures to prevention frost damage of tunnel in cold region;

Study of slope maintenance technique about water level change area in cold region

Research on energy-saving technique of exterior wall for urban house in cold regions;

At last,it points out some lessons for our country\'s building design in cold regions as well: deferring to climate,reserving the regional feature,adopting feasible technologies.
