NUPI Industrie Italiane S.p.A. installed its ELOWEB radiant heating system in Palazzo Bentivoglio in Bologna city center, Italy. The palace was built in 1551 on the remains of the old building that was destroyed by popular fury in the spring of 1507. The decision to destroy it was made by the enemies of the Bentivoglio, who had come to see their rule of Bologna as tyrannous and had co-operated with Pope Julius II to bring about their expulsion from the city in late 1506. The city's new rulers were convinced that it was necessary to raze the house of tyrants if you wanted to prevent their return, and the Senate accordingly decreed that any emblem or sign of the Bentivoglios' past domination must be destroyed. The destruction of the palace in Via San Donato was, however, a great loss for the history of Italian art. ELOWEB is the complete system proposed by NUPI Industrie Italiane S.p.A. for efficient and alternative panel heating and cooling installations. The validity of radiant systems for heating and cooling of civil or industrial environments is appreciated and recommended not only by experts in heating and energy saving, but also by building designers and interior decorators that enhance its simplicity, functionality and aesthetics. Today, the ELOWEB System can boast many installations in small and large private residential, industrial and collective buildings such as schools, multi-purpose centers, hospitals and gyms where the savings in terms of costs and energy and safety are of primary importance.
