Evaluation Method for Heating Energy Consumption of Rural Buildings in Cold Zone

Evaluation of heating energy consumption plays an important part for promoting rural building energy efficiency. Key Evaluation factors were selected and grouped from diversified factors that can affect heating energy consumption of rural buildings in cold zone by using variance analysis method according to the statistical strength of association. Two-stage evaluation index system for heating energy consumption was established, and the weight coefficients of each stage's evaluation indicators were determined by constructing an improved evaluation and comparison matrix, which was based on comparisons of the strength value of association between indicators. The improved method is much superior to traditional analytic hierarchy process(AHP) which is subject to expert subjective judgement. The evaluation method of heating energy consumption provides comparably objective judgment and evaluation, and may be beneficial to putting forward the corresponding energy efficiency improvements.
