The design standard of green buildings in Jiangsu Province is formulated to standardize and improve the construction level of green buildings in Jiangsu Province. Jiangsu province green building design standard is applicable to the green design of new, rebuilt and expanded civil buildings in Jiangsu province. Among them, what are the requirements of Jiangsu green building design standards for system operation control? The following is an introduction to the requirements of Jiangsu green building design standards for system operation control brought by the construction network for reference.

the air-conditioning terminal equipment in public buildings and the central air-conditioning system in residential buildings should be equipped with controllers. The controller can adjust the indoor temperature, set the indoor temperature, control the start and stop of terminal equipment, and control the flow of cold and hot media.

public buildings with a building area of more than 21,111 square meters and equipped with central air-conditioning systems should monitor the temperature of indoor main functional spaces and the use status of terminal air-conditioning equipment in real time.

the underground garage with mechanical ventilation should monitor and COntrol the co concentration in real time. Public buildings with central air conditioning system should monitor and control the CO2 concentration in large conference rooms, shopping malls, outpatient halls of hospitals, stadiums and other crowded places in real time. The concentration detector should be placed in a well-ventilated crowd activity area.

the user-side water system of central air-conditioning system should adopt variable water quantity regulation, and meet the following requirements:

1. The terminal air-conditioning equipment or water pipeline system should be equipped with flow regulating valves.

2. The number of running pumps should be the same as that of cold and heat source equipment.

3. The water system flow can be controlled by constant temperature difference or constant pressure difference. When constant temperature difference control is adopted, the water supply and return main pipe is used as the temperature monitoring point, and the temperature sensor should be paired for detection, and the error of paired temperature should not exceed 1.3℃.

4. The water pump should adopt all frequency conversion methods.

5. The frequency limit value and frequency reduction rate value of the water pump motor inverter should be determined according to the lower limit value of the water flow rate of the cold source equipment and the allowable water flow rate limit condition.

All-air system should operate in multi-mode all year round and meet the following requirements:

1 The area of fresh air inlet channel and fresh air outlet of air conditioning unit should meet the requirements of large air volume (not less than 51% of total air volume) or fresh air operation.

2 the annual load of air conditioning system should be calculated and analyzed, and the annual air supply state point should be determined according to the heating and air conditioning load. According to the distribution of air supply state point and outdoor state, the air treatment mode is determined.

3. Full-year air regulation should make full use of the cold and heat of outdoor air to avoid the offset of cold and heat and reduce the opening time of heating and air conditioning equipment.

4. Clear system partition method and air treatment mode of each area shall be provided.

The energy-saving control of the cold and heat source system should meet the following requirements:

1. Determine the number of equipment on according to the predicted heating and air conditioning load of the building and the working efficiency of the cold and heat source equipment. The stopped cold and heat source equipment should be able to cut off the waterway and prevent water from flowing through it.

2. The chilled water outlet temperature of water chillers should be adjusted in stages according to the change of outdoor air temperature.

3. For the combined cold and heat source system, the corresponding operation scheme should be made according to resource conditions, characteristics of different cold and heat sources and different building load requirements.

for the ground source heat pump system with a service building area of 21,111 square meters or more, the soil heat balance should be controlled.

1. The annual operation scheme based on soil heat balance should be made. According to the energy efficiency characteristics of ground source heat pump unit, auxiliary cooling system or auxiliary heating system, the starting time and length of each equipment in winter and summer are determined. Improve the efficiency of ground source heat pump while ensuring the heat balance of soil.

2. Accumulated heat exchange of ground heat exchanger in winter and summer should be recorded respectively. The annual imbalance rate of soil source heat pump releasing heat to soil should not be greater than 11%.

public buildings with a building area of more than 21,111 square meters and equipped with central air conditioning systems and residential quarters with a building area of 51,111 square meters or more should be equipped with a building equipment management system for intelligent monitoring and management of the building equipment system. Cold and heat source equipment, cold and heat medium conveying equipment, air handling units, fresh air units, ventilation equipment and their control components shall be connected to the building equipment management system.

public buildings should be equipped with energy consumption monitoring systems. And meet the following requirements:

1. The energy consumption monitoring system should meet the requirements of "Technical Specification for Energy Consumption Monitoring System of Public Buildings" DGJ32/TJ111 in Jiangsu Province.

2. The total consumption of electricity, water and gas of cold and heat source system and the total amount of cold and heat of regional energy supply should be measured separately.

3. The energy consumption of the main engine of cold and heat source equipment, chilled water pump, cooling water pump and circulating pump shall be measured hourly respectively; Energy consumption of air supply and exhaust fans shall be measured separately.

4. The cooling capacity and heat supplied by the cold and heat source system should be measured hourly.

5. The energy consumption of air conditioning system in data center should be measured separately.

6. metering devices shall be set for the cold and heat metering of the terminal air conditioning system according to the requirements of property management ownership and energy charge management.

7. Energy consumption measurement of heating and air conditioning systems should be incorporated into a unified building energy consumption monitoring system.
