Owner approach of sustainability

From the project design and construction drawing to the final construction completion, the project is always positioned in the sustainable development of green buildings. Through the deepening discussion on all stages of the project, the green building technology is effectively integrated with the building itself and the surrounding environment, by using the best technical solution for China's green building two-star and US LEED silver requirements.

Under the full consideration of the local natural climate conditions in Nanjing, a number of green ecological and building energy-saving technologies suitable for commercial buildings have been adopted. Firstly, increasing the shading for road and square, reducing heat island intensity, planning public transportation facilities properly, and connecting the underground vehicles, controlling surface rainwater runoff properly with reaching 55% of the total annual runoff control rate, selecting energy-saving lights, adopting intelligent lighting control system and advocating efficient lighting. Additionally, selecting level 1 water-saving appliances, high frequency use sanitary wares are all inductive, adopting the water-saving irrigation method equipped with the soil moisture sensor and also rainy-day automatic shutdown system, setting the indoor CO2 and air quality (PM10, formaldehyde) monitoring system. By using the intelligent cloud management system, which is researched and developed independently by the Wanda Group with intellectual property rights, the project has realized the all-round and three-dimensional management of fire protection, security, equipment, operation and energy savings. Specifically, the energy consumption of the electromechanical system is automatically recorded and stored in the database every 10 minutes to create big data for operational management, which purposes for providing opportunities for further energy saving potential. Through the integrated application of the above technologies, the energy saving rate is 65.00%, the non-traditional water source utilization rate is 8.14%, the renewable energy power generation provides 0.4% of the building electricity consumption, the solar hot water supply ratio is 12%, and the recycled building material ratio is more than 10.05%.

Through the application of a series of green building technologies, it aims to solve the problems relating to land saving, water saving, energy saving, material saving and environmental protection, and provide excellent shopping and leisure places for surrounding residents while integrating better into the surrounding environment.

Architectural description

The project set up Huiyun intelligent management system, integrating 16 light-current systems and more than 30,000 information points on one management platform, realizing all-round and three-dimensional management of realization of fire protection, security, equipment, operation and energy saving in this commercial plaza. Specifically, the energy consumption of the electromechanical system is automatically recorded and stored in the database every 10 minutes to create big data for operational management, which purposes for providing opportunities for further energy saving potential. Huiyun system can collect passenger flow information, business and operational data and environmental parameters of the square, and upload it to the group headquarters in real time for big data analysis and auxiliary operation management. The management personnel can remotely access the platform through the mobile terminal network, which can conveniently and quickly monitor the operation of each square subsystem. Even if it is overseas, it can be queried anytime, anywhere, find and solve problems, and truly realize the intelligent operation and management of Wanda Plaza. After applying Huiyun system, the number of property management personnel in a single shopping center is reduced by 11 people, and the annual labor cost can be saved by about 580,000 yuan.

In 2017, “Huiyun Intelligent Management System” won the “Global Top 50 Digital Transformation and Innovation” award from the International Data Group (IDG). 

If you had to do it again?

1. During the construction of the project, the construction drawing design has many problems, such as pipeline cross collision, conflict with structural components and unreasonable pipeline elevation. Through Wanda's BIM model, such problems are solved in the drawing stage at the initial stage of construction.
2. In view of the low-level intelligent operation and management system of shopping malls, there are some problems, such as over-reliance on management personnel, huge management team, uneven management level and responsibility, high building energy consumption. Huiyun intelligent management system is researched and developed independently by the Wanda Group with intellectual property rights to solve the problems mentioned above. Through Huiyun intelligent management system, 16 light-current systems and more than 30,000 information points of the building are integrated to one management platform. It creates the energy consumption management system, by setting smart metering tools to record the electricity consumption and water consumption of each commercial rental unit to realize independently metering and charging management. It can also calculate the energy consuming through classified energy consumption categories, process automatic measurement, record automatic statistics. Huiyun intelligent management system includes many characters, including the management calendar has built-in annual HVAC operation mode, lighting in public area automatically determines the number of lights to be turned on according to the weather, night lighting automatically lights up according to sunrise and sunset time, real-time display information about equipment operating status and environmental quality parameters, air conditioning system automatic operation ensures Indoor environmental quality, intelligent lighting control system that instantly illuminates all fixtures and automatically monitors real-time status.

Indoor Air quality

Building indoor CO2 test concentration（mg/m3）：800

The project sets indoor CO2 and pollutant concentration monitoring system to monitor the CO2 concentration in the cinema lobby, cinema hall and indoor pedestrian street in real time. In total of 37 measuring points are set up, linked with the fan control, and incorporated into the building equipment monitoring system. The specific control measures are as follows:

   Fresh Air System control: When the indoor pedestrian street CO2 concentration is higher than the setting value 100ppm, the system in the corresponding area is turned on; when the setting value is lower than 100ppm, the system in the corresponding area is turned off.

Combined air handling unit control: When the outdoor air enthalpy value in the cooling season is higher than the indoor air enthalpy value, or during the heating season, the opening of fresh air system valve and return air valve are automatically adjusted according to the indoor CO2 concentration control. if the CO2 concentration is 50 ppm higher than the setting value, the fresh air system valve opening degree is increased, while the CO2 concentration is 50ppm lower than the set value, the fresh air valve opening degree is reduced. The upper limit of the fresh air valve opening degree is 70%, and the lower limit is 15%. The CO2 sensor is wall mounted and is located indoors near the return air outlet.

Large air-conditioning areas such as supermarkets, retail collection stores, electrical appliances, video games, sub-main stores, baby kings, cinema auditoriums, cinema lobbies, etc., use full air system with single fan. Indoor pedestrian street shops and theme restaurants use fresh air system with fan coils. The indoor pedestrian street public area and the atrium are equipped fresh air system with ceiling units. The theater projection mezzanine, the theater audience corridor, and the cinema office area use fresh air system with fan coil. The commercial management staff restaurant uses fresh air system with fan coil.

The combined air treatment unit of the full air system and the combined fresh air treatment unit of the fresh air system are provided with a primary to medium efficiency filter on the fresh air side, and a filter screen is arranged on the exhaust side. The fresh air side primary to medium efficiency filter ensures the air quality of the indoor personnel space, and the exhaust side filter helps to remove indoor pollutants, ensure the exhaust air quality, and reduce the impact on the atmospheric environment.
