This research aims to develop a decision tree model for understanding actual gas consumption in residential buildings. Extending previous studies, this study examined to what extent four different type of factors, building characteristics, socio-demographics, psychological factors and household behaviour can explain actual gas consumption of Dutch households in 2017 and 2018. Data were collected from 601 households. A novel approach, a decision tree method, revealed that household gas consumption was related to building characteristics, socio-demographics, and psychological factors, while energy-related behaviour in households was not uniquely related to gas consumption. Specifically, house size, building age and residence type (building characteristics), household income and employment status (socio-demographics), and most notably egoistic values, hedonic values, environmental self-identity, perceived corporate environmental responsibility of the energy provider, and social norm (psychological factors) predicted total actual household gas consumption. These results illustrate that the novel integrated framework introduced in the paper yields a better understanding of actual household gas consumption. The results have important practical implications and suggest that it would be important to target these three type of factors in policy aimed to reduce household gas consumption.

本研究旨在建立决策树模型，以了解住宅建筑物中的实际天然气消耗。在先前研究的基础上，本研究考察了四种不同类型的因素（建筑特征，社会人口统计学，心理因素和家庭行为）在何种程度上可以解释2017年和2018年荷兰家庭的实际天然气消费。数据收集自601户家庭。一种新颖的方法，即决策树方法，揭示了家庭用气量与建筑特征，社会人口统计学和心理因素有关，而家庭中与能源有关的行为并非与用气量唯一相关。具体来说，房屋大小，建筑年龄和居住类型（建筑特征），家庭收入和就业状况（社会人口统计学），以及最显着的利己主义价值观，享乐价值，环境自我认同，对能源提供者的公司环境责任感以及社会规范（心理因素）预测了实际的家庭总天然气消耗。这些结果说明，本文介绍的新颖的集成框架可以更好地了解实际的家庭燃气消耗。结果具有重要的实际意义，并建议在减少家庭燃气消耗的政策中针对这三种类型的因素具有重要意义。这些结果说明，本文介绍的新颖的集成框架可以更好地了解实际的家庭燃气消耗。结果具有重要的实际意义，并建议在减少家庭燃气消耗的政策中针对这三种类型的因素具有重要意义。这些结果说明，本文介绍的新颖的集成框架可以更好地了解实际的家庭燃气消耗。结果具有重要的实际意义，并建议在减少家庭燃气消耗的政策中针对这三种类型的因素具有重要意义。
