摘　　要：节能减排是世界各行各业的必然趋势,建筑业作为我国排放量的龙头更应当重视。以热平衡原理为依据可以建立一个计算室内温度的公式,并通过此式能够得出在不同的保温材料和厚度以及锅炉热水的温度和流量的情况下室温随时间变化的曲线,同时也可以对各要素进行对室温变化的敏感性分析。此模型可以给建筑设计和选材提供技术和理论依据,使得节能减排能被运用到实际建造中去。Energy saving and emission reduction is the world＇s direction now, and the emission of construction industry is on the top of all the industries. Then a model used to analysis the indoor heat supply and preservation is given, which is based on heat-balance theory. This formula shows us the curves which describe the relationships between time and other elements＇ change. The elements are heat preservation material, the ply of the materials, the temperature of water and the volume of it. At last sensitivity analysis is used to compare the sensitivities of all the elements toward the indoor temperature. This model can offer technology or theory for architecture design and material choice and energy saving and emission reduction to be actual.
