At the end of the 90s, with the introduction of changes in the regulatory documents of the Russian Federation №3 to SNiP II-3-79*, regulatory requirements for thermal protection of buildings were revised towards increase. For this reason, the buildings built till 2000 don't conform to modern requirements. The actual solution of this problem is to carry out works on renovation of facades of the existing buildings with the use of innovative materials. As object of research one of educational cases of Peter the Great St. Petersburg Polytechnic University has been chosen, where by practical consideration the size of the actual thermal resistance of external walls has been determined by heat flux meter, the numerical value of which was significantly lower than the standard values. Based on the obtained data two modern ways of thermal insulation of facades (Ventilated Façade System (VFS) and External Thermal Insulation Composite System (ETICS)) have been analyzed, the assessment of energy saving potential and the discounted payback period of the investments directed to warming of facades has been made
