为了克服建筑能耗预测模型在建筑设计阶段的应用不足,通过解耦方法建立了建筑能耗快速预测模型.以中国冬冷夏热地区典型建筑为研究对象,依据传热学的基本原理,将影响建筑能耗的因素分为运行属性因素和自有属性因素两类,以运行属性参数为基准,自有属性参数为修正,依据主元解耦方法,建立了典型建筑冷热负荷计算快速预测模型,并验证了该数学模型的准确性.研究结果表明:与软件Energy Plus相比,该模型计算结果的相对误差在1.5%以下;与实际运行数据相比,该模型计算结果的相对误差在2011年为13.14%,2012年为8.56%,其主要原因是建筑的同时率分别高于设计值16%和13%;与软件Energy Plus和Design Builder相比,该模型计算快速、简捷且能够用于设计阶段.该建筑能耗快速预测模型对建筑的设计和运行优化具有一定工程价值.
In order to overcome the insufficiency of building energy consumption forecasting model in the stage of building design, a fast prediction model of building energy consumption was established by decoupling method.With the typical buildings in the winter, cold and hot areas of China as the research object, based on the basic principles of heat transfer, The factors of building energy consumption are divided into two kinds of operational attributes and their own attributes. Based on the operational attributes, their own attribute parameters are revised. Based on the principle and principal component decoupling method, a fast prediction model of typical building cooling and heating load is established , And verify the accuracy of the mathematical model.The results show that: compared with the software Energy Plus, the relative error of the model calculation results below 1.5%; compared with the actual operating data, the relative error of the model calculation results in 2011 This was 13.14% annually and 8.56% in 2012, mainly due to the simultaneous construction rates of 16% and 13% higher than the design values respectively. Compared with the software Energy Plus and Design Builder, this model is computationally fast and easy to use Design stage.The rapid prediction model of building energy consumption has certain engineering value for the design and operation optimization of buildings.
