Our country’s location in the hot tropical zone, where summer temperatures frequently breach 40°C, has significantly increased investments required for cooling. According to the India Cooling Report, these costs have risen at an annual rate of 9% over the last decade. This trend has been accompanied by a rapid increase in air-conditioning usage which, due to its greenhouse gas emissions, further pushes the temperature needle upward. Under such circumstances, there is a pressing need for investments that can simultaneously reduce electricity consumption costs as well as greenhouse gas emissions.
LuminX cool roof paint effectively addresses this dual challenge. With a high Solar Reflective Index (SRI) of 120—the best in its category—it reflects up to 95% of incoming solar radiation, reducing absolute roof temperatures by 10–15°C and internal temperatures by 5–7°C.
Key Benefits and Return on Investment
Energy cost reduction:
LuminX can reduce cooling loads by 25–30%, with some users reporting reductions of up to 35% in air-conditioning costs. Peak cooling demand has dropped by as much as 20% in certain client facilities, such as Swiggy warehouses in Gurgaon. Commercial applications have reported year-on-year electricity cost savings of approximately 30%.
Return on investment:
LuminX offers one of the fastest payback periods among available alternatives. A typical double-coat application has a payback period of roughly two years, accelerated by energy savings and available incentives (e.g., Telangana Cool Roof Policy, Ahmedabad Cool Roof Policy, among others). The Indian Green Building Council (IGBC) indicates that certified products like LuminX are life-cycle cost-effective.
Extended roof life:
LuminX protects roofs from UV damage, thermal expansion, and weathering. Its nanoparticle-infused technology and acrylic base make it highly hydrophobic, rendering surfaces waterproof and preventing dampness or leakage. This can significantly extend roof lifespan while reducing maintenance requirements.
Low emissions and environmental footprint:
Higher energy demand necessitates increased fossil fuel combustion in a thermal energy–dependent country like India, creating a vicious cycle of rising greenhouse gas emissions and peak energy demand. LuminX aims to break this cycle by reducing peak cooling loads. It is low in volatile organic compounds (VOC) and is a green-certified product that promotes responsible consumption.
Additional Advantages
Faster payback:
In non–air-conditioned or fan-cooled homes, benefits are realised immediately after the application of LuminX. It is also significantly more affordable than alternatives such as PU sheets or green roofs, which often have high upfront costs beyond the reach of lower-income households.
No space or structural limitations:
LuminX can be applied on roofs of all types (RCC, asbestos, metal, etc.) without adding weight or creating structural concerns, unlike metal panels or PU sheets.
Complementary to solar installations:
Experts recommend applying reflective coatings before or alongside solar panel installation, as cooler surfaces enhance panel efficiency. ReflectON, our in-house reflective sheet, is specifically designed for bifacial solar panels to improve their overall performance.
LuminX is a proven and scalable solution for heat-related challenges across the country. Its affordability reinforces our vision of eliminating cooling as an elitist concept—ensuring that lower-income households are also included. For homes and commercial enterprises with high cooling needs but limited budgets, LuminX offers one of the highest immediate returns on investment among available upgrades.
