Overview

Continental Automotive Singapore partnered with Resync to enhance energy efficiency while maintaining optimal thermal comfort. Resync’s AI-driven Smart Building Solution was deployed to optimize the facility’s ACMV system, focusing on energy reduction and improved indoor air quality.

Client: Continental Automotive Singapore
Building Type: Industrial Facility
HVAC System: Packaged Air Handling Units (PAHU)

Challenges

• High Energy Consumption: The PAHUs were consuming excessive energy due to suboptimal operation.
• Thermal Comfort Variability: Some areas experienced warmer conditions due to insufficient airflow.
• Manual Adjustments: Frequent manual overrides impacted the effectiveness of automated optimizations.
• Airflow Issues: Certain levels (e.g., CA1 Levels 5 and 6) had poor ventilation, contributing to discomfort.

Resync’s Smart Solution

Resync implemented a data-driven approach using AI and IoT to enhance the HVAC system’s efficiency:

• AI-Based Energy Optimization
  • Automated adjustments to PAHU operations based on real-time environmental data.
  • Smart algorithms reduced energy consumption without compromising thermal comfort.

• Occupant-Centric Comfort Control
  • Temperature and humidity were dynamically adjusted to maintain optimal indoor conditions.
  • The system was fine-tuned to ensure optimal automation while maintaining user comfort.

• Enhanced Air Quality Management
  • CO2 levels were continuously monitored, with 771 ppm for CA1 and 615 ppm for CA3 (below the 1000 ppm threshold).
  • Recommendations were made to install controllable fresh air dampers to further improve airflow and comfort.

Key Results

• 13.8% Reduction in Total AHU Energy Consumption
  • CA1 achieved a 15.9% reduction.
  • CA3 achieved an 11.9% reduction.

• Optimized Thermal Comfort
  • Indoor temperatures averaged 23.8°C (CA1) and 24.1°C (CA3) with 60-61% relative humidity.
  • PMV (Predicted Mean Vote) maintained within the optimal comfort range.

• Improved Air Quality
  • CO2 levels in CA3 remained within ideal thresholds, ensuring a well-ventilated environment.
  • Recommendations were made to install controllable fresh air dampers to further improve airflow and comfort.

Conclusion

Resync’s Smart Building Solution successfully optimized Continental’s energy usage, reducing operating costs while maintaining a comfortable and healthy indoor environment. Further refinements, including mechanical investigations and the installation of fresh air dampers, could unlock additional efficiency gains.
