The What-if-Analysis is a software tool that aims at providing building users with tailored recommendations on how they can reduce building energy consumption and energy costs. For that purpose, different strategies for engaging user into more energy-efficient behavior have been investigated and a catalogue of energy conservation measures has been elaborated. These energy conservation measures consists of different simple actions on the building energy system that a building user (resident, facility manager, staff, etc.) can undertake. These actions shall support the user saving energy and removing the bad habits that lead to energy wasting. These energy conservation measures consist for example of:
To make it possible for a software tool to automatically identify and evaluate proper energy conservation measures in real time during building operation, modern technics from the field of data analysis and artificial intelligence are utilized. Especially, one big challenge in making the What-if-Analysis tool resides in its ability to be used in any kind of building regardless of its existing technical systems, its end-users and available information. Fraunhofer IIS EAS is developing this tool that will be integrated into the overall eTeacher software package.
The theory of nudges comes from behavioural science and was pioneered by Nobel-winning Richard Thaler. It is now being studied as an alternative strategy to help reduce household energy waste.
