An Online ‘Face to Face’ Focus Group Approach for Understanding How Household Energy Use and Green Investment Decisions Differ by Personality Traits
In a UK context, encouraging the uptake of energy efficiency measures at the household level is an ongoing challenge of ever-increasing importance. A combination of economic and psychological factors influence green investment decisions and so this study aims to determine whether online focus groups are a viable means of interacting and evaluating the effectiveness of personality tailored marketing strategies. Here, we present the learnings from …
Tracking a city’s center of gravity over 500 years of growth from a time series of georectified historical maps
It is surprising difficult to define where a city center lies, yet its location has a profound effect on a city’s structure and function. We examine whether city center typicality points can be consistently located on historical maps such that their centroid identifies a meaningful central location over a 500-year period in Southampton, UK. We compare movements of this city center centroid against changes in the geographical center of the city as…
City-wide building height determination using light detection and ranging data
The research presented in this paper addresses a current gap in the availability of building geometry data and provides estimates of individual building characteristics at city scale. Such data are crucial for a wide range of subjects such as modelling building energy consumption as well as regional housing market studies. However, such data are currently not available in the UK. In this work, a new approach was developed to automatically estimat…
Ensuring statistics have power
In this paper we address ongoing confusion over the meaning of statistical significance and statistical power in energy efficiency and energy demand reduction intervention studies. We discuss the role of these concepts in designing studies, in deciding what can be inferred from the results and thus what course of subsequent action to take. We do this using a worked example of a study of Heat Pump demand response in New Zealand to show how to appr…
Sick and stuck at home – how poor health increases electricity consumption and reduces opportunities for environmentally-friendly travel in the United Kingdom
Research on the determinants of direct and indirect energy use has identified a range of relevant socio-economic factors. However, we still know little about possible influences of people's health on their energy use. Do people in poor health use less energy because they are on lower incomes, or do they have additional domestic energy needs as they spend more time at home? Does poor health reduce mobility for all or just some (environmentally-fri…
The Role of Digital Trace Data in Supporting the Collection of Population Statistics – the Case for Smart Metered Electricity Consumption Data
Debates over the future of the UK's traditional decadal census have led to the exploration of supplementary data sources, which could support the provision of timely and enhanced statistics on population and housing in small areas. This paper reviews the potential value of a number of commercial datasets before focusing on high temporal resolution household electricity load data collected via smart metering. We suggest that such data could provid…
Student project allocation using integer programming
The allocation of projects to students is a generic problem in many universities within the UK and elsewhere, not only in engineering but also in various other disciplines. This paper defines the student project allocation problem explicitly by an objective function and a number of constraints. Two integer program models are presented, the first of which is a dynamic program. A general purpose solver is used to solve the models, and the input fil…
