We deliver resilient, cost-saving climate control by harnessing renewable energy with our intelligent thermal storage.
cooling and heating are typically the largest energy loads in public and industrial buildings—driving high electricity bills, peak demand charges, and carbon emissions. Sun Ice Energy turns HVAC into a renewable-powered, grid-positive asset by combining solar PV, high-efficiency chillers, and patented PCM thermal batteries to store cold and deliver it exactly where and when it’s needed.
CORE VALUE
Escape rising energy prices, achieve dramatic savings, and gain grid independence for your building’s largest energy load: heating and cooling. Sun Ice Energy enables predictable operating costs, improved energy resilience, and stronger sustainability performance—without compromising comfort.
Why This Matters for Public & Industrial Buildings
Public and industrial facilities operate long hours with variable occupancy and large enclosed volumes. Our solar-driven thermal storage helps reduce exposure to volatile electricity pricing, maintain comfort during grid instability, and support positive “net-zero” and ESG objectives.
- Reduce exposure to volatile electricity pricing and peak demand penalties
- Maintain comfort through grid instability and extreme weather
- Improve energy efficiency and lower total cost of ownership (TCO)
- Support decarbonization, ESG reporting, and net-zero building strategies
Cut HVAC Costs to positive “Near Zero” with 24/7 Renewable‑Powered Comfort.
HOW IT WORK
Generate
Your rooftop solar panels produce renewable electricity during daylight hours.
Operate & Charge
Solar power is intelligently managed to directly power the chillers to meet real-time cooling demand and simultaneously charge Sun Ice thermal batteries by freezing PCM to build stored cooling capacity
Discharge On Demand
When the sun goes down—or during peak tariff windows—the thermal PCM buffers release stored cold to maintain stable comfort without drawing expensive, carbon-intensive grid power.
Technical Performance Highlights
- Peak load reduction (peak shaving) to cut demand charges
- Thermal load shifting to maximize solar energy utilization
- Lower compressor cycling time and improved HVAC lifespan
- Seamless integration with chilled water HVAC and Building Management Systems (BMS)
- Modular architecture scalable for large public and industrial buildings
The Bottom Line for You

F.A.Q
It depends on the building size, insulation quality, and cooling load.
During design, we work with the architect to size the solar array and thermal energy storage buffer so that solar provides the primary cooling energy year‑round.
Yes. Sun‑Ice can provide heating by pairing the system with a reversible heat pump.
The heat pump produces hot water, which is circulated through the Sun‑Ice system, allowing it to operate like a highly efficient, fan controlled radiator.
Maintenance needs are low.
The system has few moving parts and no chemical battery cells.
Routine checks are similar to standard cooling equipment.
Sun‑Ice uses solar energy to freeze a thermal energy storage buffer during the day.
That stored cooling is then released to keep the building comfortable at night or during cloudy periods.
No electrical batteries are required when used with Grid support.
Sun‑Ice works best in hot, sunny climates where cooling demand is high.
It performs well in tropical, subtropical, and desert regions.
