Renewable Energy (RES) Technologies in Buildings and Built Environment

The world energy production system is today in the crossroad of changing from the application of centralized power production based on fossil fuels to the local-decentralized one, in which the renewable energy (RES) technologies associated with a conceptual energy management system is going to play the key-role. Integration of RES technologies in buildings and built environment have been rapidly grown in last decades, and this trend should be strained in order to meet the energy and environmental targets of UN Framework Convention on Climate Change (UNFCCC). Among the classic and well-developed technologies, such as solar, hydro and bio- mass, new technology challenges coming into the light. Enhanced geothermal systems, hydrogen, ocean and tidal technologies are some good examples of the forthcoming competitive technologies of the energy market. Within this framework, this special issue is intent to shade light on existing and future development of efficient RES technologies. The special issue includes, but not limited to, the following themes: (a) solar, (b) shallow and deep geothermal, (c) biomass, (d) wind, (e) hydro, (f) ocean and tidal energy and technologies, (g) analysis and energy efficiency of existing and future energy technologies, (h) energy efficiency models for RES integration into future cities, (i) Sectoral modeling of RES, (j) RES monitoring in development countries and economies in transition (k) assessment of RES policies/measures, (l) other topics relevant to RES technology efficiency modeling, development, and policy.
