The Energy Concept Adviser (ECA) is an electronic tool assisting in the design of renovations/retrofits focusing on energy savings of educational buildings (schools, university buildings and nursery schools). It will provide a potential list of solutions to specific energy related problems associated with the building shell, lighting or HVAC systems. The ECA contains more that 30 descriptions of exemplary retrofit/renovation projects and provides a wide and varied selection of retrofit technologies and strategies. The ECA will energy rate an existing educational building versus the national average for varied energy sources. Additionally, a calculation tool will provide energy savings and costs for retrofit technologies/strategies selected to be considered for improving the energy efficiency of the educational building.
Who is the target group of the Energy Concept Adviser?
The ECA was developed for educational building decision-makers and their staff, responsible for programming, planning and accomplishing the retrofit/renovation of existing facilities. With the use of the ECA, the energy saving potential within an existing building will be better understood during the development of a retrofit/renovation projects and therefore reduce the energy consumption of an existing building. The decision-makers will be provided with reliable information on conventional and innovative strategies and technologies and thereby gain improved planning reliability.
Who has developed the Energy Concept Adviser?
The Adviser was developed in the framework of the International Energy Agency (IEA) in the project Annex 36 of the Energy Conservation in Buildings and Community Systems Programme. Experts from 9 European countries and the USA brought in their national expertise, case studies and retrofit technologies to promote energy savings in the retrofit/renovation of existing buildings. See also 'Info&Contact'.
How to operate the Energy Concept Adviser?
The user-interface is developed for intuitive use; the information paths shall be recognized intuitively. Additional information in the retrofit concept development part is provided under '?'. The main navigation bars are reached by clicking on the project logo on the upper left side of each page.
The ECA computer program has been developed as a decision support tool for educational buildings. It was prepared under IEA ECBCS programme Annex 36 - 'Retrofitting of Educational Buildings' under the leadership of the Operating Agent Hans Erhorn from the Fraunhofer Institute of Building Physics (IBP), Stuttgart.

This is the first and international version of the ECA. The national experts of the participating countries surveyed the careful development. Still the software could contain bugs. Users should carefully review the results to make sure that they are credible and consistent. If bugs or inconsistencies should occur, please inform your national representative (see information within the ECA).
