Existing buildings are responsible for more than 40% of the world’s total primary energy consumption. Current building management systems fail to reduce unnecessary energy consumption and preserve user comfort at the same time mainly because they are unable to cope with dynamic changes caused by user’s...

Research is often inspired by visions of the future. These visions can take on various narrative forms, and can fall anywhere along the spectrum from utopian to dystopian. Even though we recognize the importance of such visions to help us shape research questions and inspire rich design spaces to be...

Cloud Computing is often regarded as form of "green computing". However, the growth of cloud computing also goes hand in hand with an increasing demand for energy, caused by a continuously growing demand for content, data-intensive applications and bandwidth. The debates on the energy implications of...

Green software is currently gaining interests with the increasing impact of IT in energy consumption. Green-ness in software however, can be achieved at various stages of the Software Development Life Cycle (SDLC). Consequently, several software engineering concepts can be adopted for achieving greener...

Sustainability is a normative concept, building on ideas such as justice, equity and responsibility, and based on human culture and society. Computers, internet, and the technologies that are central in our network society embed also normative values and are part of a cultural context. But the work looking...

In research and development of information and communication technologies for sustainability, there is a strong belief that human behaviour can be monitored at the individual level to generate different signals, and that these signals can be used to influence individuals to behave differently. We analyse...
