Case Study: Energy Savings and Data-Driven Maintenance with SkySpark

Client: GreenTower Office Complex 
Industry: Commercial Real Estate
Location: Central Europe

Challenge

GreenTower Office Complex, a 12-story multi-tenant office building, struggled with rising energy costs and frequent HVAC system failures. The existing BMS (Building Management System) collected vast amounts of data but lacked actionable insights. Facility managers needed a smarter way to monitor performance, reduce energy waste, and anticipate maintenance needs.

Solution

Smart Digital Services and Analytics implemented a full SkySpark project onboarding and management process, focusing on data integration, energy analytics, and predictive maintenance.

1. Onboarding with Haystack Standard

   • Normalized over 5,000 data points from HVAC, lighting, and energy meters using the Haystack tagging standard.

   • Automated onboarding scripts reduced manual configuration time by 40%.

2. Custom Dashboards and Reporting

   • Developed dashboards to track real-time energy use, equipment efficiency, and tenant comfort KPIs.

   • Configured automated reports delivered weekly to facility managers and stakeholders.

3. Rules & KPIs for Data-Driven Insights

   • Deployed over 120 custom Spark and KPI rules to detect inefficiencies such as simultaneous heating/cooling and abnormal energy spikes.

   • Implemented data quality processes to ensure reliability of insights.

4. Predictive Maintenance

   • Designed rule-based alerts to identify early signs of equipment wear (e.g., fan motor vibration, chiller efficiency drops).

   • Integrated notifications with the client’s CMMS (Computerized Maintenance Management System) to streamline maintenance scheduling.

Results

• 18% Energy Savings within the first year through optimized HVAC scheduling, reduced equipment run hours, and detection of hidden energy waste.

• 30% Fewer Unplanned Breakdowns by shifting from reactive to predictive maintenance.

• Improved Tenant Comfort due to proactive issue resolution and real-time monitoring.

• ROI in 14 Months from reduced energy bills and maintenance costs.

Conclusion

Through SkySpark onboarding and ongoing management, Smart Digital Services and Analytics transformed GreenTower Office Complex into a data-driven, energy-efficient, and resilient building. By leveraging actionable insights, the facility team achieved measurable savings while enhancing comfort and reliability.
