The need for new strategies and implementation tools, for education and training is addressed in the final chapter as part of the nZEB concept, towards sustainable communities. The concept is discussed further in a chapter on advanced solutions for water re-use and recycling wastes as second raw materials. These two chapters discuss the problem of conversion efficiency at the level of components and systems, aiming at giving value to the variable renewable energy sources, in producing thermal and electric energy. Advanced solutions to cover the energy needs by using various renewable-based energy mixes are presented in two chapters.
The book starts with a chapter that addresses problems related to the energy demand and renewable energy sources available in the built environment, along with the restrictions and opportunities in developing sustainable, efficient and affordable solutions, also gaining aesthetic and architectural acceptance. Usually commercial software or games are produced for sale or to serve a commercial purpose.This book addresses the main challenges faced today in implementing the Nearly Zero Energy Buildings (nZEB) concept. Even though, most trial software products are only time-limited some also have feature limitations. After that trial period (usually 15 to 90 days) the user can decide whether to buy the software or not. Trial software allows the user to evaluate the software for a limited amount of time. Demos are usually not time-limited (like Trial software) but the functionality is limited. In some cases, all the functionality is disabled until the license is purchased.
