This paper explores the efficiency and effectiveness of radiant heating and cooling systems in office buildings, aiming to provide sustainable and energy-efficient solutions. Indoor thermal environment in buildings has been studied for many years, highlighting the importance of thermal comfort and the continuous development of technologies to enhance indoor environments. An innovative material, foamed aluminum, currently under research, was assessed for thermal comfort for employees in an open office. The results show high thermal conductivity of the material and a rapid response of the system. Foamed aluminum radiant ceiling panels provide optimal thermal comfort for year-round operation, although deficiencies were observed in terms of assessing relative air humidity during the winter months. Based on experimental measurement of innovative radiant heating/cooling systems placed in office spaces is clear, that so called foamed aluminum panels can improve the operation of such systems, guarantee the hygienic required indoor environment during the whole year and provide the optimal energy operation for winter and summer period.
