Case Study: Application of Ganzkuhl PDRC Coating at Nest Builders Container Office

ByQgen Team

Introduction

Nest Builders, a prominent construction and real estate development company based in Chennai, India, is known for delivering innovative and sustainable building solutions. The company operates a container office made of metal, serving as a mobile and modular workspace for their on-site operations. These metal structures, while versatile, are prone to excessive heat build up, impacting occupant comfort and productivity.

Q Gen-Next Sustainable Technology Pvt. Ltd., the innovator behind Ganzkuhl®, specializes in eco-friendly products designed to reduce energy consumption and enhance environmental efficiency. Their flagship product, Ganzkuhl® PDRC Coating, is a ceramic-based Passive Daylight Radiative Cooling coating that reflects up to 98.6% of solar heat, significantly lowering surface temperatures and offering waterproofing benefits.

Need for Coating

Nest Builders faced significant challenges with their metal container office at a construction site in Chennai. During peak summer conditions, the metal surfaces absorbed intense solar heat, causing indoor temperatures to soar, which led to discomfort for staff and increased energy costs for cooling. A sustainable solution was needed to reduce heat build up, improve working conditions, and align with Nest Builders’ commitment to eco-friendly practices. Ganzkuhl® PDRC Coating, applied by their trusted applicator partner Hydrotrident Coatings, was selected to address these challenges.

Pre-Coating Temperature Readings

Before applying Ganzkuhl® PDRC Coating, temperature measurements were taken on the metal surfaces of the container office during peak summer conditions. The recorded surface temperatures ranged from 58°C to 59°C, indicating substantial heat absorption, which created an uncomfortable and inefficient working environment.

Coating Application

Ganzkuhl® Premium Grade was chosen for the project, with Hydrotrident Coatings overseeing the application process. The metal surfaces were thoroughly cleaned using high-pressure water jetting to remove dirt and rust. Two coats of Ganzkuhl® Base Coat were applied by brushing, followed by a single coat of the Top Coat after the base coat had dried completely. The application adhered to the recommended guidelines, and the coated surfaces were left to cure for 24-48 hours under sunlight to ensure optimal performance.

Post-Coating Temperature Readings

After the coating had cured, temperature measurements were conducted under similar peak summer conditions. The results showed a significant reduction in surface temperatures, dropping to 35°C to 36°C. This decrease of approximately 20-23°C highlighted the high reflectivity and emissivity of Ganzkuhl® PDRC Coating, effectively cooling the metal surfaces and improving the indoor environment of the container office.

Conclusion

The application of Ganzkuhl® PDRC Coating at Nest Builders’ container office delivered remarkable results, reducing surface temperatures from 58-59°C to 35-36°C. This substantial cooling effect created a more comfortable and productive workspace for staff, while also reducing the need for energy-intensive cooling systems. The project, executed by Hydrotrident Coatings, underscores Nest Builders’ dedication to sustainable construction practices and demonstrates the efficacy of Ganzkuhl® as a cutting-edge solution for heat management in metal structures.
