Paints as a Scalable and Effective Passive Daytime Radiative Cooling (PDRC) Technology
Excessive heat poses significant challenges for warehouses, impacting worker comfort and goods integrity, and increasing energy costs associated with cooling. Retrofitting older warehouses to meet modern cooling demands is a complex and costly endeavour, often needing substantial infrastructure modifications. However, integrating passive and alternative cooling solutions offers a promising avenue for addressing these challenges.
Cooling paint is one passive cooling solution that is widely available, but with varying degrees of success. Unlike conventional paint, cooling paint incorporates special additives and reflective pigments that deflect sunlight, thereby preventing heat absorption and reducing indoor temperatures. Studies have demonstrated that cooling paints can achieve surface temperature reductions of up to 10 to 20 °F compared to conventional paints.
White paint does not provide highly effective PDRC
Knowing that companies are in need of effective heat solutions, many paint makers have labelled white paint as a cooling product. While white paint does reflect sunlight and therefore heat, its performance is far inferior to other products on the market that are designed with cooling in mind. Pirta paint not only reflects heat, but also facilitates its release from the surface of a structure. This strategy increases its cooling capabilities far beyond that of a plain white paint.
PDRC decreases mechanical cooling demand
Cooler surface and indoor temperatures decreases the need for mechanical cooling systems, curbing energy consumption. By diminishing reliance on air conditioning systems, cooling paint helps decrease electricity consumption and associated carbon emissions, yielding cost savings for warehouse operators and promoting broader environmental conservation efforts. Research underscores the substantial energy-saving potential of cooling paint. For example, studies have shown that buildings treated with cooling paint can achieve cooling energy consumption reductions of up to 30%. As warehouses and other businesses increasingly prioritise energy efficiency and environmental responsibility, cooling paint is a valuable tool for achieving these objectives.
Pirta Paint is a reliable and effective cooling paint option for keeping costs, emissions and temperatures down. Developed as part of a broader initiative to address climate change through passive cooling technologies, it delivers exceptional performance in terms of solar reflectivity and thermal emittance. With an SRI (Solar Reflectance Index) of 117.6, Pirta Paint significantly outperforms other cooling paints, making it a premier choice for warehouse operators seeking sustainable and cost-effective cooling solutions. Its affordability, non-toxic formulation, and VOC-free composition further underscore Pirta Paint's practicality and environmental friendliness for warehouse applications. Its ease of application and compatibility with various building materials further enhance its appeal as a dependable cooling paint option for warehouses of all sizes.
Cooling paint – and specifically Pirta Paint – embodies a sustainable approach to surface temperature control and indoor thermal comfort, offering superior performance and reductions in energy consumption. Pirta aims to make passive cooling technologies effective, affordable, and scalable, accelerating the shift towards a greener, healthier, and more sustainable future.
