Environment-friendly ELCO heating technology for a more comfortable building The geothermal heat pump provides cold and warm water for the air-conditioning and, thanks to the innovative 4-way valve system, also serves as a source of cooling and heating. Depending on the season, the system automatically switches between cooling and heating. In winter, the system utilises the stored warmth for heating; in summer the warmth is dis- sipated. Thanks to a COP value of over 4, operating costs are reduced significantly – and the integrated ceiling cooling convectors increase the building’s comfort.

All the control units are concen- trated in one part of the building. The three systems together make it possible to save more than 50 % of the energy costs, and reduce the CO2 emission by about 10 tonnes a year. The solar installation comprises five AURON 20 DF solar collectors and a water tank. An electric auxiliary heating system is also integrated. The system offers a number of functions, such as time-dependent disinfection of the system, intelligent auxiliary heating, and protection from overheating and over- pressure. The warm water processing is thus reliable, perfectly hygienic and very convenient. Renovation: Meng Joss House – Italian Style Street A combined system makes it possible: Higher efficiency, more convenience This former military barracks, built in 1902, is the largest building in the “Italian Style Street” in Tianjin. It consists of two three-storey wings forming an L-shape. However, over the years, the striking arched windows and the open corridors were destroyed. In the course of major renovation work, it was possible to preserve the original style of the architecture completely. In addition to its historic significance, the building serves future generations as a reminder of the hundred-year history of modern Tianjin. Italian flair in Tianjin: The Italian Style Street
