Annex 55 Reliability of Energy Efficient Building Retrofitting- Probability Assessment of Performance and Cost

The International Energy AgencyThe International Energy Agency (IEA) was established in 1974 within the framework of the Organisation forEconomic Co-operation and Development (OECD) to implement an international energy programme. A basicaim of the IEA is to foster international co-operation among the 28 IEA participating countries and to increaseenergy security through energy research, development and demonstration in the fields of technologies forenergy efficiency and renewable energy sources.The IEA Energy in Buildings and Communities ProgrammeThe IEA co-ordinates research and development in a number of areas related to energy. The mission of theEnergy in Buildings and Communities (EBC) Programme is to develop and facilitate the integration oftechnologies and processes for energy efficiency and conservation into healthy, low emission, andsustainable buildings and communities, through innovation and research. (Until March 2013, the IEA-EBCProgramme was known as the Energy in Buildings and Community Systems Programme, ECBCS.)The research and development strategies of the IEA-EBC Programme are derived from research drivers,national programmes within IEA countries, and the IEA Future Buildings Forum Think Tank Workshops. Theresearch and development (R&D) strategies of IEA-EBC aim to exploit technological opportunities to saveenergy in the buildings sector, and to remove technical obstacles to market penetration of new energy efficienttechnologies. The R&D strategies apply to residential, commercial, office buildings and community systems,and will impact the building industry in five focus areas for R&D activities: Integrated planning and building design Building energy systems Building envelope Community scale methods Real building energy us
