ICT 4 E2B Forum is aimed at bringing together all relevant stakeholders involved in ICT systems and solutions for Energy Efficiency in Buildings, at identifying and reviewing the needs in terms of research and systems integration as well as at accelerating implementation and take-up.ICT 4 E2B Forum intends to promote, through community building activities, a better understanding, a closer dialogue and a more active cooperation between researchers, end-users/practitioners, building owners, technology-suppliers, and software developers as regards the use of ICT to support informed decision-making (both human and automated) in the current delivery and use of sustainable and energy-efficient buildings and districts.The ICT4E2B Forum project aims at the following objectives:-\tBring together relevant stakeholders to identify and review the needs in terms of research and systems integration-\tUpdate the REEB research roadmap-\tPromote the use and further development of ICT for improved energy efficiency of buildingsBy accomplishing these objectives, ICT 4 E2B Forum will map the sector-specific priorities into a common view and vocabulary, thereby enabling communication and understanding between experts in different sectors that need to join forces in order that fundamental improvements in energy efficient buildings can be achieved. All this coordination work will support in defining future research directions as well as in channelling efforts, while favouring consensus buildings on the roadmap itself.
