Project member João Pedro Gouveia, a researcher from CENSE – Center for Environmental and Sustainability Research (FCT-UNL), has had his latest paper Unravelling electricity consumption profiles in households through clusters: Combining smart meters and door-to-door surveys published in Energy Buildings.

This paper contributes to a comprehensive understanding of the electricity consumption profiles in a Southwest European city through the combination of high-resolution data from smart meters (daily electricity consumption) with door-to-door 110-question surveys collected within INSMART for a sample of 265 households in the city of Évora, in Portugal. It shows that this approach can deliver important results and meaningful knowledge regarding households’ electricity consumption profiles.

The analysis of the electricity consumption profiles of 10 clusters, showed four distinct types of annual consumption patterns in the municipality of Évora: U shape (soft and sharp), W shape and Flat, which might bring different insights for public policies and stakeholders decisions. U shape profile is the most common one, covering 77% of the sampled houses, and is characterized by a significant difference of electricity consumption between winter and the rest of the year unravelling the low ownership levels of air conditioning system for space cooling in Évora (confirming also the pattern at national level).

The combination of the daily electricity consumption data with qualitative door-to-door survey-based data proved to be a powerful data tool to distinguish groups of power consumers, allowing us to derive insights to support DSOs, ESCOs, and retailers to design measures and instruments targeted to effect energy reduction (e.g. peak shaving, energy efficiency) at a city level. The fieldwork was conducted in a southwestern European city; however the methodology can be applied to any region equipped with a smart metering network.

Energy and Buildings (ELSEVIER) is an international journal publishing articles with clear links to energy use in buildings. The aim is to present new research results, and new proven practice aimed at reducing the energy needs of a building and improving indoor environment quality.
