Most energy usage of buildings throughout their life cycle is during the operational stage (~80%). The decisions made in the conception and design stages of new buildings, as well as in renovation stages of existing buildings, influence about 80% of the total life cycle energy consumption.
The impact of user behaviour and real-time control is in the range of 20%. ICT has been identified as one possible means to design, optimize, regulate and control energy use within existing and future (smart) buildings.
This books presents a collection of best practices, gap analysis of current research and technology development activities, a research roadmap, and a series of recommendations for ICT supported energy efficiency in buildings. Key research, technology, and development priorities include: integrated design and production management;intelligent and integrated control; user awareness and decision support; energy management and trading; integration Technologies.
The vision for ICT supported energy efficiency of buildings in the short, medium, and long term is advocated as follows:
•Short term: Buildings meet the energy efficiency requirements of regulations and users
•Medium term: The energy performance of buildings is optimised considering the whole life cycle
•Long term: New business models are driven by energy efficient “prosumer” buildings at district level – long term.
