Sensitivity Analysis of Factors Influencing Rural Housing Energy Consumption in Different Household Patterns in the Zhejiang Province

Unlike urban dwellings, it is very common for elderly people to stay at home alone in Chinese rural families, and some families have three generations the same house who are different situations, their family patterns lead highly sensitive parameters of building energy consumption. This paper first selects most based on a questionnaire survey. The measured consumption behavior electrical parameters, time, basic were input into DesignBuilder build simulation models, these verified by comparing predicted values residential month-by-month electricity global sensitivity analysis was then conducted using software determine interactions between variables second-order Sobol index cooling load, heating comfort models obtain standardized regression coefficients (SRC) each factor parameters. results show that household had little influence ranking factors cooling, but annual discomfort significant factors. For example, model 1 showed general lighting power density when optimizing total amount goal, while one greatest degree 2 3 equipment density.
