The aim of the SmartBuild project is to develop new knowledge, integrated solutions, and technologies that will make it possible to cover our building-related energy needs with substantially less harmful environmental emissions, while still satisfying the whole range of end-user needs such as comfort, aesthetics, costs, operability, reliability and functionality. Building integrated energy systems are defined as systems in the building envelope or building structure that utilize the available on-site energy resources in a way that minimizes the need for purchased energy and maintains a satisfactory indoor environment. In this report, the systems have been categorized into passive and active systems.
