Project Background
The IBM G1 Building, located in Manyata Tech Park, Bangalore, is a modern four-story office complex. Bangalore has a tropical climate with high temperatures throughout the year, making air conditioning a major contributor to the building’s overall electricity consumption. The client sought a green energy solution capable of meeting large-scale cooling demands while significantly reducing operational costs.
Our Solution
We designed and deployed a 225 TR (780 kW) solar air conditioning system for the IBM building, featuring the following core components:
1. High-Efficiency Solar Thermal Array
-
780 sets of CPC1518 solar thermal collectors installed on the 8th-floor rooftop of two buildings
-
Total coverage of approximately 3,200 square meters
-
Specially designed CPC collectors allow for direct flat installation without any south-facing inclination, greatly simplifying rooftop structural requirements
-
Capable of harvesting solar thermal energy for over 340 days per year, fully leveraging Bangalore’s abundant solar resources
2. Thermal Storage & Conversion
-
System generates 90,000 liters per hour of 95ยฐC solar hot water
-
Equipped with a 30,000-liter buffer tank to ensure stable energy supply
-
High-temperature hot water serves as the heat source to drive a 225 TR absorption chiller
-
Consistently delivers chilled water at 7โ9ยฐC, meeting the cooling requirements across all four office floors
3. Intelligent Automation & Control
-
Fully automatic operation with multiple controllers for safety and automation
-
Both end-users and installers can monitor and control the entire process in real time
-
Ensures safe and stable system performance even under extreme heat conditions
| Key Metrics | Performance |
|---|---|
| Electricity consumption reduction | ~90% |
| Current system power consumption | Only 27 kWh/hour |
| Annual effective operating days | >340 days |
| Investment payback period | ~4.4 years |
The system has enabled IBM to dramatically cut air-conditioning season electricity costs while significantly reducing the building’s carbon footprint through clean energyโsupporting the company’s broader sustainability and ESG goals.
