•GSHP air-conditioning system as a mature green technology , with its outstanding energy saving efficiency and zero emission feature, has long been recognized and used in advanced countries such as Swiss; Denmark; Sweden etc. While in China, the application of such technology is just on its way up. Currently, in 3.3 billion sq.m. old buildings,only a small percentage has implemented some kind of energy saving techniques. As the big part of building energy consumption, Nobao’s GSHP central air-conditioning eco-system has unimaginable market potentials.
