            In 2013, MOHURD of China and the World Bank co-organized and implemented a project called "China urban buildings energy saving and renewable energy application program" funding by Global Environment Facility, targeting to promote low carbon and livable cities, increase energy efficiency of public buildings and commercialize roof solar PV system. In this issue, there are 6 articles introducing the energy planning methods and energy micro-net building.

            • Some key points in urban demand side energy planning
            • Hydraulic calculation of pipe network in energy bus system
            • Feasibility of fuel cell-based CHP systems applied to public buildings

            Since April 1st of 2017, the nitrogen emission from new boilers must be limited to the cap of 30mg/m3. Beijing plans to finish the low nitrogen emission retrofitting of boilers in 1,500 communities. In 2017 Gas-fired boilers low nitrogen and high efficient technology application conference held on March 31st, the experts and representatives from manufacturers discussed the technology roadmap and shared experience and case studies, as well as proposed the sustainable development which will promote the high efficient and low nitrogen emission products and technologies application.
            • A parallel combined system with required number of wall-mounted boilers
            • Energy saving deployment for heating system of gas-fired water boilers
            • Case study: Pre-mixed condensing boiler application

            9th Retrofitting technologies conference for existing buildings
            • Time: April 20th-21st
            • Venue: New Fangzhou Hotel, Hunan
            New buildings and existing buildings retrofitting have become the new normal of China construction industry. To push the development of new urbanization and advanced energy retrofitting technology, China Academy of Building Research will organize a technology conference in Changsha of Hunan including 6 sub-conferences: green livable retrofitting, indoor environment and healthy building, low energy consumption retrofitting, building industrialization and green retrofitting, green materials application, building energy efficiency and air quality improvement for hospitals.

            3rd New technologies forum on data centers air conditioning systems
            • Time: May 23rd
            • Venue: Beijing Yulong Hotel
            With accelerating of industry upgrading and structure adjustment, new technologies representing by artificial intelligence and virtual reality are blooming, which pushes the development of big data industry including internet, finance, insurance and e-business. Data center industry is entering into a large scaled constructing stage. The 3rd forum will present the trend of data center, case studies, standards, operation and management experience and energy retrofitting, as the theme of "Safety, green and high efficiency".

              China HVAC system market demand analysis
            Urbanization becomes a largest diver of future development of China economy and is one of the important factors impacting the demand of central air conditioning system in China. According to the data from National Bureau of Statistics of China (NBS), in the past 10 years, urbanization rate of China increased from 43.00% in 2005 to 56.10% in 2015, but still a huge gap comparing with developed countries. Chinese Academy of Social Sciences predicted that urbanization rate of China will reach 61% and 65% in 2020 and 2025, respectively. Driven by urbanization, commercial deployment and public infrastructure will bring great new demand for central air conditioning industry.

            High GWP gases face 30% price increase
            Refrigerant users face new price increases of as much as 30% as Europe transitions away from high GWP HFCs. Many chemical manufactures - Chemours and Mexichem announced to increase prices of their refrigerants by 15-25%, including R404A, R410A, R507, R134a and R407C. Latest European Commission figures report that the amount of HFC refrigerant placed on the market in 2015 amounted to 168Mt CO2eq - within the baseline cap amount for the year of 183Mt CO2eq. Next year the industry, faced with cuts of 37% of the baseline, must make do on 115Mt CO2eq.

            New IRENA Study finds eliminating energy-related carbon emissions possible
            Global energy-related carbon dioxide (CO2) emissions can be reduced by 70% by 2050 and completely phased-out by 2060 with a net positive economic outlook, according to new findings released by the International Renewable Energy Agency (IRENA). The buildings, industry and transport sectors need more bioenergy, solar heating and electricity from renewable sources that substitute conventional energy. Electric vehicles need to become the predominant car type in 2050.
