The adoption of energy efficiency practices and increased penetration of renewable energy sources in the power system are estimated to play a key role in the decarbonization of the energy sector, helping reduce greenhouse gas emissions and ultimately fight climate change. To foster energy transition, energy education initiatives should primarily target the citizens and be designed adopting a User-Centered Design (UCD) approach and HCI methodologies. This paper describes how UCD/HCI can inform the design of citizens’ energy education initiatives by presenting a case study—the development of an information platform targeting Madeiran citizens. The article describes the design process, from ideation to prototype and validation. Methods used in each phase (card sorting, semi-structured interviews, brainstorming sessions, think-aloud protocol and surveys) are described. Results of each phase and how they have informed the following steps are presented, together with a detailed description of the resulting information platform and initial results in terms of acceptance and interaction with the system. Our initial results support the hypothesis that adopting an HCI perspective can nurture the development of energy education initiatives targeting citizens, bringing a user-centered approach to the design of such initiatives.

Portugal is the country in Europe where the death rate in winter and summer has the highest correlation with outdoor temperatures. The Portuguese National Institute of Public Health Ricardo Jorge has developed a national warning system for heat waves called ICARO, which has been in place since 1999 (and is the oldest in Europe). However, it presents some limitations, namely, the low spatial resolution (five regions in Portugal’s mainland), the low temporal forecasting period (one day), and the fact that it was only accessible to health authorities until very recently. This work describes the development of a new public dashboard that uses a new early warning index for extreme weather events, the CLIMAEXTREMO index, which extends the current warning system by improving the current forecasting models for risk by integrating new sources of public data and increasing the spatial and time resolution of the warnings to the municipality or the parish level. The new index is a combination of a new model to estimate the relative mortality increase (updating the model used in ICARO) together with a model of the indoor temperature of building archetypes for all municipalities and a vulnerability index that considers socio-demographic economic indicators. This work discusses the results of the new risk indicator for the heat waves that occurred in Portugal at the end of June and mid-August 2023, and it shows that the index was able to indicate a high risk for the municipalities that had an increase in the number of deaths during that period.

Web-immersion – i.e., a deep sense of cognitive and perceptual absorption engendered by the content and interactive features of a website - plays an important role in our modern, digital world. Yet, this topic has received little attention from design and HCI scholars. The lack of tools to assess and measure immersion in the Web may severely limit our ability to understand the nature of such experience, thereby constraining future research in the area. To address this issue, we designed a questionnaire for assessing immersive websites and conducted a preliminary evaluation on it. In this article, we outline the questionnaire design and report on findings from a preliminary study conducted to analyse its reliability and validity. Moreover, we present results from Factor Analysis performed to investigate the dimensionality of the instrument. Finally, we conclude by discussing the implications of our findings, along with limitations of the study and future work.
