Household energy consumption and carbon emissions for sustainable cities – A critical review of modelling approaches

Abstract

11The purpose of this paper is to conduct a review of how household energy consumption and carbon emissions (HECCE) modelling 12 paradigms have evolved over the years. This is achieved by adopting the literature review methodology for the study. The paper first 13 reviewed the previous studies that are serving as the theoretical framework underpinning the HECCE models. Further to this, the paper 14 identified an array of energy models that have evolved over the years together with their capability of analysing energy consumption and 15 their associated carbon emission trends in housing sector of the economy. The results of the study showed that econometric (mainly 16 top-down), building physics, and statistical (mainly bottom-up) methods are the existing approaches that have found application in mod-17 elling HECCE issues. However, a number of limitations were noticed in these existing modelling techniques. These are (1) lack of trans-18 parency in the model algorithms, (2) inability to account for the complex, interdependencies, and dynamic nature of the issue of energy 19 consumption and carbon emissions, (3) limited evidence to show for the occupants-dwelling interactions, and (4) lack of enough capacity 20 to accommodate qualitative data input. And as such, the study concluded that there is the need to scout for more robust and sophisti-21 cated modelling approaches that take into consideration the kind of complexity involved in issues relating to HECCE. 22

A review and critique of UK housing stock energy models, modelling approaches and data sources

“…HSEMs poorly describe the influence of occupants and their behaviour on energy demands [30], likewise local climatic conditions [74]. In previous reviews of HSEMs [12,74,105], a set of performance gaps have been identified. The first set is related to data resolution: a) a reliance on iso-…”

A critical review on questionnaire surveys in the field of energy-related occupant behaviour

“…This model tries to predict behaviour as a result of a variety of predictors that determine a person's intention towards a specific behaviour. This framework is widely used in many different fields of pro-environmentalist, occupant and consumer behaviour and in building energy research fields as well (Chen and Knight 2014) ) (Gao et al 2016) (Oladokun and Odesola 2015) (Staddon et al 2016). Schwartz and Bilsky defined values as beliefs pertaining to desirable end states or mode of conduct that transcend specific situations and guide choices and actions (Schwartz and Bilsky 1990).…”
