However, the aforementioned system primarily collects and analyzes building construction energy consumption and cannot directly and quickly adjust energy consumption and carbon emissions at the construction site.

[0048] In this embodiment, the data transmission network 21 includes a LoRaWAN network, an NB-IoT network, and a WiFi network.

[0049] LoRaWAN is a low-power wide-area network (LPWAN) communication protocol running on LoRA. LoRaWAN has been recognized as an international standard for LPWANs. LoRa is a physical layer protocol that uses spread spectrum modulation and supports long-range communications. It transmits data using a narrowband waveform with a central frequency, making it resilient to interference. Establishing a LoRaWAN network requires deploying a LoRa gateway to enable data upload from specific energy consumption data collection terminals. Typical models include the KerlinkiBTS and TEKTELICKONA.

[0050] NB-IoT (NarrowBand Internet of Things) is a cellular-based narrowband IoT technology and the optimal connection technology for low-power wide-area IoT (LPWA). It carries the foundational connectivity for smart homes, smart mobility, smart cities, and other intelligent worlds. It is widely used in areas such as smart metering, smart parking, smart streetlights, smart agriculture, and white goods, making it one of the foundational connectivity technologies in the intelligent era. NB-IoT networks generally use operator NB-IoT base stations, such as the Huawei DBS3900 and ZTE QCell.

[0051] Wi-Fi is a very common wireless network technology. By deploying WiFi APs (such as Cisco C1100, Huawei AP6500, etc.), specific energy consumption data collection terminals can upload data.

[0052] Data transmission network 21 simultaneously includes LoRaWAN, NB-IoT, and WiFi networks, forming a heterogeneous converged communication architecture with the following advantages: 1) Wide coverage, meeting the needs of diverse scenarios: LoRaWAN and NB-IoT are both low-power wide-area (LPWAN) technologies, enabling wide-area coverage and suitable for long-distance, low-rate data transmission. WiFi networks can provide high-rate, low-latency data transmission within a local area, making them suitable for close-range, high-volume data exchange. The three networks complement each other, covering diverse communication ranges from local to wide areas, meeting the needs of various application scenarios. 2) Flexible device access, supporting a diverse range of terminals: LoRaWAN and NB-IoT networks can connect to a large number of low-power, low-cost IoT devices, such as sensors and meters. WiFi networks can connect to a variety of terminals, including smartphones, tablets, and industrial control equipment. Different devices can flexibly select the appropriate network based on their characteristics and application requirements, achieving efficient and cost-effective data transmission. 3) Large network capacity, supporting a large number of devices: LoRaWAN and NB-IoT use narrowband transmission, enabling the concurrent access of a large number of devices within limited spectrum resources. Through rational channel planning and network deployment, WiFi networks can achieve high network capacity within a local area. The combination of these three networks can support the access and data transmission needs of a large number of devices in industrial applications. 4) Excellent transmission performance, meeting diverse application requirements: Although LoRaWAN and NB-IoT have lower data rates, they offer long transmission distances and low network energy consumption, making them suitable for low-speed, low-power applications. WiFi networks offer high transmission rates and low latency, making them suitable for applications with high real-time and data volume requirements. Based on requirements for real-time data transmission, reliability, and security, the appropriate network or combination can be selected to optimize transmission performance. 5) Easy deployment and maintenance, reducing system complexity: LoRaWAN and NB-IoT can reuse existing communication infrastructure (such as carrier networks), reducing the cost of building dedicated networks. WiFi networking offers flexibility, allowing for rapid deployment and adjustment based on site conditions, facilitating localized coverage and data aggregation. A unified network management platform enables centralized management and operation of heterogeneous networks, reducing system complexity and maintenance costs. 6) Strong interoperability, enabling seamless data integration: Through gateways, protocol conversion, and other technical means, interoperability between LoRaWAN, NB-IoT, and WiFi networks can be achieved. Data collected from different networks can be aggregated onto a unified platform for storage, processing, and application, enabling seamless integration of all types of data. Data integration facilitates comprehensive perception of the industrial environment, optimizes production processes, and improves the scientificity and effectiveness of decision-making.

[0077] In this embodiment, the storage battery is a lithium-ion battery. In addition, the capacity of the storage battery is generally 10% to 60% of the average daytime electricity consumption of the construction site.

[0078] The following is an estimate of the construction electricity usage for a hypothetical large commercial building project:

[0079] 1) Project Overview:

[0080] Building area: 50,000 square meters

[0081] Construction period: 18 months

[0082] Average number of construction workers: 200.

[0083] 2) Main electrical equipment:

[0084] Tower cranes: 2, each with a power of 100kW

[0085] Construction elevators: 4 units, each with a power of 20kW

[0086] Welding machines: 10 units, each with a power of 10kW

[0087] Air compressor: 2 units, 50kW each

[0088] Lighting and household electricity: 50kW.

[0089] 3) Estimation process:

[0090] Calculate the total power consumption of the device:

[0091] Tower crane: 100kW×2=200kW

[0092] Construction elevator: 20kW×4=80kW

[0093] Welding machine: 10kW×10=100kW

[0094] Air compressor: 50kW×2=100kW

[0095] Lighting and household electricity: 50kW

[0096] Total equipment power = 200 + 80 + 100 + 100 + 50 = 530kW

[0097] Estimated average daily electricity consumption:

[0098] Assuming the equipment works for 8 hours a day, the total daily power consumption is:

[0099] 530kW×8h=4240kWh

[0100] Estimated electricity consumption during the entire construction period:

[0101] Assuming 26 working days per month and 468 working days in 18 months, the total electricity consumption during the construction period is:

[0102] 4240kWh / day × 468 days ≈ 1984MWh

[0103] Therefore, under this assumption, the average daily electricity consumption during the construction period of the construction project is approximately 4240kWh, and the total electricity consumption during the entire construction period is approximately 1984MWh.

[0104] In this embodiment, the data aggregation gateway 31 specifically adopts Advantech AIIS-3410 industrial computer.

[0105] In this embodiment, the energy storage management module 42 adopts an existing product, such as ABB Ability™ OPTIMAX energy storage management system of ABB.

[0106] Energy storage management module 42 can be used to configure construction site energy storage device 5 to charge at night and when green electricity is available, and to discharge during the day. By optimizing the energy storage device's charging and discharging strategies through the energy storage management module, multiple benefits can be achieved, including peak load shifting, green electricity consumption, cost reduction, and reliability improvement, promoting efficient energy utilization and sustainable development at construction sites.

[0107] The aforementioned building construction energy consumption management system incorporates a construction site energy storage device connected to both the external power supply network and the construction site power network. This device can store electricity when the external power supply network is adequately supplied and release it during peak construction site power consumption periods, achieving efficient energy utilization and directly and rapidly reducing energy consumption and carbon emissions. The external power supply network can include a green electricity supply network, thereby increasing the proportion of renewable energy use and reducing fossil energy consumption. Furthermore, by integrating the construction site energy storage device into the building construction energy consumption management system, it is possible to couple building construction energy consumption monitoring with energy storage management, providing a basis for optimized energy storage control and enabling direct and rapid adjustments to energy consumption and carbon emissions at the construction site.
