_Energy-Smart Buildings_ intends to provide a brief research source for building technology and regulations in terms of energy efficiency, as well as discussing fundamental aspects and cutting-edge trends for new buildings and retrofitting the current building stock. Additionally, sources of renewable and sustainable energy production and storage are reviewed, with case studies of such systems on buildings in a cold climate. This volume provides industry professionals, researchers and students with the most updated review on modern building ideas, and renewable energy technologies that can be coupled with them. It is especially valuable for those starting on a new topic of research or coming into the field.
