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
- Reduce HVAC grid energy use by up to 100% during peak hours (project-dependent)
- Achieve ROI in 1 to 7 years (reference: Shanghai ATEQ building – 14.72% ROI)(depending on local electricity cost)
- Stay ahead of sustainability mandates and position your building as a leader in clean energy
- Stabilize operating costs and reduce carbon footprint without compromising comfort

F.A.Q
The system is engineered with enough storage capacity to handle most cloudy periods.
For large buildings, the grid can supplement the system if needed.
Yes. Sun‑Ice uses water or flame retardant PCM materials in sealed metal containers, contains no lithium, and is designed for long‑term, low‑risk operation.
The system is also non toxic and is highly recyclable at end-of-life.
Yes — but only during a major renovation where the building is taken back to its structural frame with state of the art insulation and ventilation.
Sun‑Ice is primarily designed for new construction, where it can be fully integrated into the building from the start.
Sun‑Ice stores thermal energy, not electricity.
This makes it:
- More efficient for cooling applications
- Longer‑lasting (batteries have a limited life cycle for daily storage)
- Lower‑maintenance
- Safer (no lithium, no “run away” risk)
- More cost‑effective for large cooling loads
Sun‑Ice is designed for new buildings with strong insulation and high‑performance envelopes.
The better the insulation, the lower the cooling load — and the more efficiently Sun‑Ice units operates.
We work closely with architects to optimise:
- Building orientation
- Insulation levels
- Shading and solar control
- Ventilation strategy
- Thermal mass and envelope performance
This integrated design approach ensures the building requires as little cooling as possible.
