            Indoor air pollution directly causes to the diseases such as asthma, chromic obstructive pulmonary disease (COPD), cardiovascular disease and lung cancer. The central government of China paid highly attention to indoor air quality and developed a series of research and standards & laws. Until now, we have seen that 1) the control index is upgraded to related to environmental and operational pollution including PM2.5 and mould; 2) constructing process is more comprehensive covering design, construction, inspection and operation; 3) control path is more systematic, changing from source control to integrated control of source, ventilating, purifying and thermal environment and building energy efficiency as well.

              China clean energy consumption accounting for 22.1% in 2018
            Mentioned by Mr. Qi Chengyuan, deputy director of National Energy Administration at 2019 International forum on clean energy development, in 2018, China clean energy consumption accounted for 22.1% of the total energy consumption and non-fossil energy consumption accounted for 14.3%. The installation capacity of hydropower, wind power and PV power in China is at the top of the world.

            Low efficient products is phasing out
            In order to promote green consumption, improve high qualified development and lead green lifestyle, co-released by National Development and Reform Commission(NDRC ) and other government departments, "Green and high efficient refrigerating action plan"(Plan) is encouraging consumers to choose high efficient products.

            New energy efficiency grades standards will be implemented next May
            The revising parts include 1) the assessment system changes from EER to APF; 2) new standard covers fix speed products and inverter products; 3) put the energy efficiency of ducted air conditioner as a single standard, named as "Minimum allowable values of energy efficiency and energy efficiency grades for ducted air conditioner" (GB 37479-2019); 4) the new standard is also applied to water –cooled unit, air conditioner for computer room and data center, etc.
