At Clima Solutions, our commitment is to Performance × Elegance—transforming passive interiors into Active Thermal Systems that deliver measurable results. This intelligence is powered by Phase Change Material (PCM) technology, which stores and releases latent heat to actively stabilize indoor temperatures and reduce energy demand.
This compilation of global case studies serves as the data-backed validation for our approach, proving that integrating PCM is a scalable, effective, and economically viable solution for modern commercial properties worldwide.
Case Study 1: The Commercial ROI in Indian Hospitality
The business case for PCM is most compelling when deployed in large-scale commercial retrofits.
Application: PCM layers were strategically applied to the external wall assemblies of a 16-floor Indian hotel.
Measurable Results: This strategic retrofit resulted in a significant 6% reduction in total energy consumption and successfully maintained guest comfort across changing seasons.
Financial Performance: This investment delivered a rapid payback period of approximately 4 years and an astonishing >500% ROI over 25 years. This confirms that PCM is a highly cost-effective retrofit strategy for commercial real estate.
Case Study 2: The Critical Role of Control in North American Banks
An independent study on the use of PCM ceiling tiles in bank buildings in Minnesota, USA, provided the most crucial insight into operational reliability.
Application: PCM ceiling tiles (Templok) were installed above suspended ceilings in commercial bank buildings.
Savings Potential: When the control protocol was optimized, the system demonstrated immense potential, achieving up to 29% in cooling savings and up to 34% in heating savings.
Strategic Imperative: The study concluded that achieving these results was highly dependent on strict HVAC operation and consistent night setbacks. This validates Clima Solutions' model: high performance is conditional upon Energy Intelligence and automated control strategies (IoT Monitoring).
Case Study 3: Thermal Stabilization in Composite Climates (Jaipur, India)
Research demonstrated the effectiveness of integrating PCM directly into the building fabric to manage solar heat gain in warm climates.
Application: Paraffin-based PCM (RT18HC) was integrated into bricks used for wall construction in Jaipur's composite climate.
Measurable Results: The PCM-enhanced bricks resulted in a 12% reduction in cooling energy consumption. This directly correlated with a reduction in the indoor air temperature of approximately 1.2°C.
Takeaway: This proved the viability of using PCM-enhanced walls to mitigate solar heat gains transmitted through the building façade.
Case Study 4: Performance in High-Humidity and Temperate Zones
Global data confirms the universality of the PCM application, regardless of local climate severity.
Tropical Climate (Singapore): Research using simulations showed the potential for 10-15% cooling energy savings and an indoor temperature reduction of up to 1°C in high-humidity conditions. Performance was further enhanced when combined with reflective coatings.
European Temperate Climate: A European residential project that integrated PCM into walls and ceilings achieved substantial long-term results.
Savings included 30% cooling energy savings and 16% heating energy savings.
The system provided significant thermal comfort, resulting in a temperature stabilization that reduced peak temperature fluctuations by ~4°C.
The payback was achieved in a swift 7-10 years under European energy pricing.
Comparative Insights: Optimizing Your Investment
These studies collectively highlight key factors for maximizing the performance of your ClimaTec system:
Proven Savings Range: Across all climates, PCMs consistently demonstrate cooling energy savings between 10% and 30%.
Strategic Placement: False ceilings prove most effective for reducing solar heat gain, while wall integration is crucial for overall thermal stabilization. This validates Clima Solutions' separate ClimaTec Ceilings and ClimaTec Walls systems.
Technical Specifications: Optimal performance requires correct PCM selection based on its phase change temperature and a thickness of 10-15 mm.
Longevity: PCM integration is a high-value, long-term investment, with durability studies showing the material can last 20+ years with minimal maintenance.
The data is clear: PCMs represent a scalable, effective, and economically viable solution for high-performance commercial projects that demand measurable impact.
