Evaluation on energy conservation of a full-scale wood structure house

The heat transfer coefficients of the envelope for a full-scale wood structure house are calculated. The index of heat loss of building and index of coal consumption for heating of the house are derived according to the design standard. The conclusions are as follows: The heat transfer coefficients of the envelope such as the outer door, the windows and the composite floor are satisfied with the design except the composite wall and roof. So the thicknesses of the wood structure are added for both the wall and roof, and the results meet the requirements of energy conservation of 50%. The index of heat loss of building and index of coal consumption for heating of the house are 30.27 W/m² and 31.4 kg/m², respectively. Because the shape coefficient of the house is 0.585, even if the heat transfer coefficients of the wall and roof are decreased, the index of heat loss of building and index of coal consumption for heating only drop to 25.21 W/m² and 26.2 kg/m², respectively.
