Article
Gamification is increasingly being used by organizations to foster work-related competencies and employee motivation. In the current body of gamification literature, there is a dearth of design knowledge about systems that foster the development of employee competencies through effective gamification approaches. The aim of this paper is to set the...

Harnessing benefits and preventing harms of AI cannot be solved alone through technological fixes and regulation. It depends on a complex interplay between technology, societal governance, individual behaviour, organizational and societal dynamics. Enabling people to understand AI and the consequences of its use and design is a crucial element for...
Chapter
Sustainable energy is hands down one of the biggest challenges of our times. As the EU sets its focus to reach its 2030 and 2050 goals, the importance of energy efficiency for energy consumers/prosumers becomes prevalent. Over the years, a lot of different approaches have been followed to engage end-users and affect energy-related occupant behaviou...
Chapter
This paper presents the evaluation results of an improved version of an interactive tool for energy demand and supply forecasting, based on the combination of explainable machine learning with visual analytics. The prototype applies a kNN algorithm to forecast energy demand and supply from historical data (consumption, production, weather) and pres...

This paper presents the design and a prototypical implementation of a tool for short-term energy demand forecasting in prosumer scenarios in local energy systems. The prototype combines explainable machine learning and visual analytics to facilitate the forecasting and analysis of energy demand and supply in a way usable for small utilities not use...
Chapter
As part of the energy transition, the spread of prosumers in the energy market requires utilities to look for new approaches in managing local energy demand and supply. Doing this effectively requires better understanding and managing of local energy consumption and production patterns in prosumer scenarios. This situation is particularly challengi...
Article
In this paper we describe the socio-technical approach developed in the POWER project extending traditional forms of citizen engagement for local sustainability challenges with a collective awareness platform in order to increase public awareness, knowledge and engagement. We show how a citizen-centered design and implementation process integrating...

Conference Paper
The use of IoT technologies (e.g. smart metering, smart home) and persuasive techniques to support energy-saving behaviour in households has been increasingly researched. Studies suggest that effective designs of such systems should incorporate different types of feedback with motivational techniques and energy saving advice [4]. But to be effectiv...

Full-text available
In a world affected by the constant growth and concentration of the population in urban areas, the problem of preserving natural resources has become a priority. A promising approach to resource conservation is demand management, i.e., the ability to positively influence the behaviour of the population towards more sustainable consumption. Informat...
Conference Paper
Full-text available
The application of gamification does not always achieve the expected results due to the shortcomings of the quite common “one size fits all” approach of standard gamification concepts. We therefore propose a design framework that can inform systematic development of adaptive gamification applications. The developed framework draws on the current bo...
