Introduction

In today’s fast-paced healthcare environment, hospitals are under immense pressure to deliver exceptional patient care while minimizing operational costs and meeting sustainability goals. Energy efficiency has emerged as a key factor in achieving these objectives, particularly in large facilities like National Hospital. At Resync, we provide AI-driven energy management solutions tailored to optimize energy usage, maintain thermal comfort, and support sustainability efforts in hospital & commercial buildings.

Challenges in Energy Management for Hospitals

Hospitals operate 24/7, consuming vast amounts of energy to support common areas like lobbies, waiting rooms, and other spaces. These areas require consistent thermal comfort and better air quality, making energy efficiency a top priority. Some of the key challenges include:

1. 1. High Energy Demand: Large hospitals account for significant energy usage due to their size and the need for uninterrupted operations.

1. 1. Thermal Comfort and Indoor Air Quality: Maintaining optimal indoor temperatures and air quality is crucial for the comfort of patients, visitors, and staff.

1. 1. Operational Costs: Rising energy costs add financial strain to already tight budgets.

1. 1. Sustainability Compliance: Hospitals are increasingly required to meet environmental standards and reduce their carbon footprints.

National Hospital Surabaya: A Case Study

The National Hospital in Surabaya, Indonesia, exemplifies how Resync’s energy management solutions address these challenges. This 9-storey hospital consumed between 550,000 and 603,000 kWh per month, with air conditioning systems accounting for 52% of total energy usage. The facility faced significant issues, including high energy consumption, lack of automated control, and inefficient manual facility management for 536 fan coil units (FCUs).

Key Challenges

• • High Energy Costs: Monthly energy bills ranged from $38,800 to $41,000.

• • Manual Management: The lack of real-time asset monitoring led to inefficiencies and ad hoc maintenance.

• • Thermal Comfort: Fluctuating indoor temperatures impacted staff productivity and patient comfort.

Solution Implementation

How Resync Transformed National Hospital’s Energy Management

Resync implemented a comprehensive energy optimization solution, leveraging AI-driven systems and IoT-enabled monitoring tools. Key interventions included:

1. Digitalization and Real-Time Monitoring

Resync integrated smart energy meters and onboarded 536 FCUs onto its platform. This enabled centralized control, real-time monitoring, and automated scheduling, significantly reducing manual intervention.

• • Impact: Improved operational efficiency and reduced downtime.

2. ACMV Optimization

By optimizing the Daikin VRV condensers and fan coil units, Resync reduced energy consumption and improved system performance. The AI algorithms continuously adjusted cooling based on real-time data such as occupancy levels and temperature fluctuations.

• • Result: A 27% reduction in HVAC energy consumption.

3. Enhanced Thermal Comfort

Resync’s solution ensured temperature and humidity levels stayed within the ASHRAE Standard 55-2020 comfort range. Fluctuations were minimized, creating a consistent and comfortable environment for visitors, staff and patients.

• Outcome: Achieved a median Predicted Mean Vote (PMV) within the optimal range of -0.5 to +0.5.

Results and Impact

The implementation of Resync’s solutions delivered measurable results:

• • 27% Energy Savings on ACMV: Significant reduction in ACMV energy use.

• • 19% Total Energy Savings: A marked decrease in overall building energy consumption.

• • Operational Efficiency: Automated scheduling and real-time monitoring streamlined facility management processes and reduced their man-hours.

• • Sustainability Compliance: Reduced carbon footprint and enhanced alignment with their sustainability efforts.
