Jotun Powder Coatings has affirmed its continued support towards sustainable architecture trends through ‘The Cool Shades Collection,’ a range of energy-saving and environmentally friendly powder coatings that have been specially formulated to reduce the temperature of aluminum building components exposed to the sun. ‘The Cool Shades Collection’ is a range of heat reflective architectural powder coatings that helps reduce energy consumption and improve interior comfort of inhabitants.
The company commissioned the services of German sustainable architecture consultancy and research firm, ai³, to conduct a study on the impact of the Total Solar Reflectance (TSR) value on the users comfort and the energy performance of buildings. TSR is the fraction of solar energy that is reflected by a coated surface. The
study covered the observation of simulation buildings, where heat reflective coatings were used on opaque parts of the facade, across five key cities—Istanbul, Bangkok, Doha, Shanghai and Sydney. Two types of window systems were observed during the process: the non-insulated and the highly insulated type, which is generally used in cold climate locations. The observations made in Doha, which represented the Middle East aspect of the study, were conducted on a residential building model containing 80 apartments and 20 floors with the building orientation towards the south.
“Over the years, Jotun has demonstrated its strong support for the development of sustainable architecture by innovating solutions that comply with green standards and regulations,” said Yulia Gvozdeva, Global Product Manager, Jotun Powder Coatings. “Across the region’s construction industry, building materials used in today’s projects need to carry sustainability credits and the positive results gained from this study assures architects and developers that Jotun’s 'The Cool Shades Collection' helps them deliver more environmentally friendly and sustainable projects.”
“According to the study ‘The Cool Shades Collection’ has significantly higher TSR values than conventional coatings, which results in reduction of heat transfer inside the building during hot weather conditions, thereby contributing to higher interior comfort,” said Mr. Jager, Founder and Head of ai³. “The use of these heat reflective coatings in low insulated systems also leads to a reduced risk of contracting skin burns and irritation. In terms of energy efficiency in hot climate regions like the Middle East, the application of 'The Cool Shades Collection' on the window frames and other metal components of the building's facade leads to a reduction of energy consumption."
“The results garnered from this study support the efficiencies and benefits that can be gained from using our heat reflective coatings. ‘The Cool Shades Collection,’ which reflects our commitment to develop products that address the issue of climate change and the needs of our customers, have now become a highly preferred choice among the region’s most advanced and sustainable projects. In fact, it has been used across projects like the Olympic multipurpose hall at Al Lusail, Qatar, Siemens headquarters building for the Middle East region in Masdar City, Abu Dhabi and the King Faisal Specialist Hospital and Research Centre in Riyadh, KSA,” concluded Rene Mayer, Global Concept Manager, Jotun.
