Abstract: The ICT industry is quickly becoming a very significant consumer of global energy. This energy usage clearly comes at an environmental cost, and recent reports estimate that the industry now contributes 2% of the worlds CO2 emissions, or as much as the aviation industry. A significant part of this energy consumption can be attributed to data-centres, where huge numbers of energyintens...

Buildings account for almost 40% of energy consumption in European countries and hence are responsible for a significant part of greenhouse gas emissions. Recent regulations and standards (Minergie, Minergie P, etc.) are strongly encouraging more sustainable buildings by decreasing energy consumption and integrating more renewable energy sources. It is essential, in such a context, to evaluate ...

buildings play an important role in the energy demand sector. due to the increase of environmentalconcerns and renewable energy sources restriction, lighting control systems will play an important role in the reductionof energy consumption of the lighting without impeding comfort goals. lighting control systems can control lightingconsumption according to the type of building, adequate luminanc...

The world is currently facing a critical environmental crisis, and the shift toward renewable energy sources has become increasingly urgent [...]

Taking the UK as a case study, this paper describes current energy use and a range of sustainable energy options for the future, including solar power and other renewables. I focus on the area involved in collecting, converting and delivering sustainable energy, looking in particular detail at the potential role of solar power. Britain consumes energy at a rate of about 5000 watts per person, a...

According to the energy crisis in the world, optimization of energy consumption is indispensable. Technological advances in constructions and application of renewable energy resources demand saving energy. Atrium, as one of the construction elements, catches sufficient daylight and acts as a passive solar element and results in a decline of energy consumption. This research seeks to evalu...

Zero-energy buildings (ZEBs) are attracting increasing interest internationally in policies aiming at a more sustainably built environment, the scientific literature and practical applications. Although “zero energy” can be considered at different scales (e.g., community, city), the most common approach adopts only the perspective of the individual building. Moreover, the feasibility of this ob...

This paper by using Long-range Energy Alternatives Planning System (LEAP) constructs four different renewable energy scenarios for the Greek transport, energy, and industry sectors. By projecting the demand for renewable energy and the associated resulting carbon dioxide emissions up to the years 2020 and 2030, the paper applies in a second stage data envelopment analysis (DEA) evaluating the G...
