Big Data - Road to Smart Cities

The recent trends in social development show that in the next decades an increasing larger share of the population worldwide will live in cities. Decarbonizing the energy footprint of urban areas becomes therefore a critical point in the outlook of meeting challenging environmental targets set by Governments in many Countries and eventually fighting climate change. Optimal utilization of local resources represents a strategic area to improve the environmental efficiency of cities, and integrated operation and planning of the overall urban system is needed to optimize such efficiency. Hence, while various energy vectors such as gas, electricity, heat, and so on, have been traditionally decoupled in terms of operation and planning, the need to reduce emissions and the availability of smart grid technologies represent a significant opportunity to rethink urban energy systems. The objective of this paper is to discuss the main issues relevant to wastage of energy in the buildings and method to reduce it through the smart control devices.
