As the "dual carbon" goals advance, the building industry is facing the dual challenge of energy efficiency and occupant comfort. Coolinno's phase change energy storage building materials achieve a "constant temperature" indoor effect through the absorption and release of heat via physical state changes. Below are real-world cases from three typical application scenarios.

Case 1: Office Building in an Eco-Tech Park – Reducing HVAC Load and Achieving "Peak Shaving and Valley Filling"

Pain Point: Large temperature fluctuations between day and night in the office building, high daytime cooling energy consumption, and significant pressure on the urban power grid during peak hours.

Solution: Phase change energy storage wall panels are installed on interior walls and ceilings, with a phase change temperature set at 26°C.

Results:

1. Significant energy savings: When indoor temperatures exceed 26°C during the day, the phase change material melts and absorbs heat, delaying the startup of air conditioning systems. Comprehensive cooling energy consumption is reduced by 18%–25%.

2. Power peak shaving: During off-peak nighttime hours when electricity rates are low, the air conditioning system uses residual cooling to "charge" the phase change material; during peak daytime hours, the stored cooling is released, reducing electricity costs by 30%.

3. Improved comfort: Temperature fluctuations in office areas are controlled within ±2°C, eliminating localized overcooling or overheating.

Case 2: Rural Schoolhouse in a Severe Cold Region – Nighttime Insulation, Keeping Teachers and Students Warm

Pain Point: At a rural primary school in Northwest China, winter nighttime temperatures plummet to -15°C. Traditional electric heaters heat up quickly but also cool down quickly, with high operating costs.

Solution: Phase change thermal storage modules are installed within wall cavities, with a phase change temperature set at 20°C. During the day, they store heat using solar energy or low-cost electric heating.

Results:

1. Long-lasting insulation: After power is turned off at night, the phase change material solidifies and releases heat, maintaining indoor temperatures at 16–18°C for 6–8 hours.

2. Health and safety: Reduces fire hazards and dryness caused by running electric heaters all night. Classrooms are no longer freezing cold during morning reading sessions.

3. Economical and eco-friendly: Saves approximately 40% on heating costs per heating season, while reducing CO₂ emissions from coal-fired heating.

Case 3: High-End Data Center Server Room – Precise Temperature Control, Ensuring Equipment Stability

Pain Point: Servers generate sudden, intense heat. Traditional precision air conditioners start and stop frequently, resulting in high energy consumption and risk of downtime.

Solution: Customized phase change cooling panels are installed on rack backplanes and ceilings, with a phase change temperature of 32–35°C.

Results:

1. Emergency cooling: In the event of air conditioning system failure, the phase change material can absorb peak heat loads for 20–30 minutes, buying time for emergency power generation.

2. Uniform heat dissipation: Eliminates localized hotspots in server racks, reduces server temperature fluctuations by 70%, and extends hardware lifespan.

3. Lower PUE: Allows the air conditioning setpoint to be raised by 3–4°C, reducing the annual comprehensive PUE (Power Usage Effectiveness) from 1.45 to 1.32.

Why Choose Our Phase Change Building Materials?

1. High-efficiency energy storage: Thermal storage density is 5–10 times that of concrete, with a compact footprint.

2. Safe and stable: Non-toxic, non-corrosive, with a cycle life exceeding 10,000 cycles and no risk of leakage.

3. Flexible forms: Available as panels, microencapsulated coatings, and mortars, suitable for both new construction and retrofits.

4. Intelligent tunability: Phase change temperatures can be customized between 18°C and 35°C for different climate zones.

From office buildings to schoolhouses, from data centers to passive houses, phase change building materials are redefining "building energy efficiency." They are no longer passive insulation layers but active "temperature regulators."
