5-15%

ESG and Compliance Value:

Automated GHG inventory foundation: Established a precise energy and carbon emissions data foundation not only meets current compliance requirements but also lays a solid foundation for future carbon neutrality pathways and ESG reporting disclosures.
Enhanced brand image: Transformed into a 'green mall' to attract sustainability-conscious brand tenants and consumers, thereby increasing property value.

Customer background

Located in the core business district of Beijing's Xidan, this well-known department store is a large, multi-brand commercial space, operating for long periods and supporting high foot traffic and consumer demand. Under the premise of balancing customer experience and operational efficiency, energy management has gradually shifted from a simple equipment operation and maintenance issue to a core challenge affecting operating costs, management efficiency, and sustainable compliance.

Challenges and pain points

High electricity bills, but difficult to reduce effectively:

Energy consumption is highly concentrated in air conditioning and lighting systems, accounting for 70–80% of total energy consumption, requiring long-term operation to maintain high-sensitivity spaces. With revenue growth slowing and high electricity costs severely squeezing profits, there is a lack of systematic means to identify energy-saving opportunities.

Compliance and ESG pressures of 'falling behind if you don't upgrade':

China's dual carbon policies and the trend of mandatory ESG disclosure have emerged one after another. As a landmark shopping mall, it faces potential risks such as green building evaluations, bank credit approval, and rent negotiations, urgently needing to establish carbon management capabilities that comply with regulations.

Data is fragmented, meter reading relies on manual labor, and decisions lack basis:

With multiple brand tenants and complex food court equipment, energy consumption data scattered across counters and outdated systems, leaving management teams relying on manual meter reading and historical experience for equipment scheduling, lacking real-time, accurate data support.

Visible: Energy Diagnosis and Management Mechanism Establishment (Energy Conservation Consulting Services)

In mall operations, air conditioning, lighting, and public facilities run for long periods, but energy consumption across systems is dispersed, making it difficult for managers to know "where electricity is actually being used." Through energy inventory and flow analysis, JOSUN breaks down air conditioning, lighting, and electricity usage in each area, establishing energy KPIs and management indicators, enabling managers to clearly grasp energy consumption changes across different time periods, pedestrian flows, and regions.
👉 Turning energy from "invisible" to "manageable" effectively reduces electricity costs by about 5–10%.

Manage: Centralized Energy Management and Operational Optimization (Energy Management Platform)

In an environment where department stores have multiple tenants of multiple brands and multiple system equipment, air conditioners, elevators, and various MEP equipment often rely on on-site personnel for operation, making real-time adjustments difficult. JOSUN has introduced a one-stop energy management platform that integrates operational data from various mall systems, allowing operators to instantly monitor equipment status and dynamically adjust, based on changes in foot traffic and operating hours, such as improving air conditioning efficiency during peak hours and reducing energy waste during off-peak hours.
👉 Shifting from 'manual experience' to 'data-driven management' improves system energy efficiency by about 5–15%

Achieved: Equipment optimization and energy-saving retrofit implementation (system energy-saving retrofit project)

Under long-term operation of existing mall equipment, some system efficiency declines, but without continuous optimization mechanisms, energy-saving improvements are difficult to truly implement. Through equipment diagnostics and energy-saving retrofit projects, JOSUN optimizes and upgrades high-energy-consuming equipment such as air conditioning units and cooling systems, combined with continuous monitoring and adjustment mechanisms, making energy-saving effects visible not only in the short term but also sustainable over the long term.
👉 Ensuring effective energy savings, saving about 3 million RMB (about 12%) annually on electricity bills
