Wilsdruff, Germany<\/p>\n<\/div>\n\n\n

\n

Two multi-family buildings (MFBs) were built in the town of Wilsdruff near the city of Dresden. They have different sizes and were approached architecturally differently but still, both buildings have identical heating concepts.<\/p>\n<\/div>\n\n

\n

Keeping the systems quiet was crucial because the MFBs lie in a neighborhood with especially strict noise control regulations. Thanks to specifically designed fan blades the sound level never goes above 58 dB(A), even when the system is running on full load.<\/p>\n<\/div>\n\n

\n

Even before the German Geb\u00e4udeenergiegesetz GEG <\/em>(Buildings Energy Act) was reformed, the planners decided to go for the hybrid heating concept of heat pumps and gas boilers. The technical and financial advantages were decisive, promising high efficiency and low costs.<\/p>\n<\/div>\n\n

\n

Choosing heat pumps even without regulations in mind proves that this technology already makes sense from a economic and a practical point of view.<\/p>\n<\/div>\n\n
