Retrofitting of external walls and building façades of residential buildings is often considered as the most energy efficient renovation measure. This paper presents a web based tool for remote monitoring of energetical performance of a multifunctional façade system for apartment building retrofitting, the ‘MeeFS’ system (www.meefsretrofitting.eu/). MeeFS System is an energy efficient non-intrusive concept based on multi-module pre-fabricated components that will allow integrating both active and passive technologies for façade retrofitting. The retrofitting process is based on a combination of innovative composite façade structure materials, multifunctional and easy to install panels, technological modules as well as an efficient energy management system. Every module integrated in the façade is based on particular technologies that will allow the reduction of the primary energy either by reducing energy demand of the building or by supplying energy by means of RES (Renewable Energy Sources).
