At present, China's natural gas production and supply amount is increasing rapidly, the smart grid construction pace is accelerated, professional Service Corporations have been initially set up, national support policies are loaded heavily, all the facts prove that DES/CCHP will boom soon in China.
According to literature [1], in the condition that natural gas price is 2.5 yuan/m³, electricity price 0.80 yuan/ m³, electricity price 0.80 yuan/kWh, cooling price 0.46 yuan/kWh, for a DES/CCHP project of medium size (10MW ), investment recovery period of is less than 10 years, 40% of the proceeds comes from cold and hot water produced.

According to a recent Greek study on potential energy savings in the building sector, the most effective energy conservation measures (ECMs) are the insulation of external walls (33-60% energy savings), weather proofing of openings (16-21%), the installation of double-glazed windows (14-20%), the regular maintenance of central heating boilers (10-12%), and the installation of solar collectors for sanitary hot water production (50-80%).
It is concluded that the mode of self-transformation guided by the government and the professional persons would be feasible.

The pressure difference causes the moist air to leak from the inside through joints and untightness into the envelopment structure, which may, in turn, result in water vapours condensing and fungal growth. [2, 3] Building materials and construction type At present there are a number of building materials used in the current construction.
Diverse groups of building materials always require a professional and rigorous approach to the design and execution of an airtight building envelope.

Because human body keeps losing water in ways of evaporation and diffusion.
The measuring technique of plantar pressure is a technology to using pressure measuring equipment to analyse the plantar pressure in the process of human body's still or dynamic state.[9] People can analyse foot by this technique, designing soles for professional athletes.
