| Distributed control system plays an important role in the improvement of HVAC system control and energy consumption reduction. It is necessary to establish the new generation of building intelligent network platform technology applicable to information treatment and operation control of building indoor spaces and devices, with the need of massive information management. This issue publishes 8 articles covering the latest achievement, typical intelligent control method and engineering problems in commercial buildings and subways, which will provide an important theoretical and practical reference. |

Green community, Green building Released by National Development and Reform Commission of China, "General plan on green life initiative" indicates a significant achievement by 2022，including over 60% of community should meet the requirement and achieve clean, comfort, safe and beautiful living environment, and the proportion of green building in urban new buildings will reach 60% and the green transformation of existing buildings will achieve positive results. Ministry of Housing and Urban-Rural Development is responsible for the details. First negative grow of China central air conditioning industry in past 3 years The data show that in the first half year of 2019, China central air conditioning industry declined 4.78%, which is the first negative growth in past 3 years. The change of brands and channel will be accelerated in the whole year of 2019. It is said that in the first half, the trend of "domestic brands increase and foreign brands decrease" is shown among 50 major brands. The market share of domestic brands increased 0.23%, but Japanese/Korean and European/American brands shrank. National standard on nearly zero energy building officially implemented China is exploring the development of ultra-low energy building. Ultra-low emission and green buildings not only contribute to energy saving and emission reduction, but also coin great economic benefits. The green and energy efficiency technologies will bring a 1000 billion yuan’s market with the application of ultra-low energy consumption technologies to residential buildings, public buildings, multi-storey buildings and high-rise buildings. |
