Building with an Active Thermal Protection in Combination with High Share of Renewable Energy Sources Use

This paper presents the concept of an active thermal protection system for heating and cooling and its integration into the envelope of a school building with an area of 5200 m2. The entire system was developed using numerical simulation tools integrated into the practical application of green energy. The system uses a high proportion of renewable energy sources (thermal solar system for heating, direct cooling with underground water, heat pump) and seasonal heat storage. By measuring a number of influential parameters over a longer period of time, the correlation of simulation and applicable values was determined, and high energy efficiency and sustainability in variable external microclimatic conditions were confirmed. The average use of electricity for heating, cooling, ventilation and preparation of sanitary hot water in the period from 2015 to 2019 was below 8 kWh/m2.
