Global warming contributes to the rising surface temperature of up to 70°C which leads to the urban areas experiencing warmer air temperatures. This is a major contributor in the increased UHI [Urban Heat Island]. UHI refers to the higher temperatures experienced in dense urban areas.
MITIGATION OF UHI IMPACTS
Research & studies state the use of IR Reflective / High SRI paints & coatings COOL Reflective Surfaces is one of the most economical strategies to reduce energy usage and environmental impacts and improve occupants' health. Reduce the surface temperatures Stop the heating of the roofs, walls, and pavements Controls the heat transmittance indoors Contribute to reducing the indoor and city temperature.
The urban heat island (UHI) effect is a common environmental problem occurring in metropolitan areas in which the air temperature is significantly higher than in suburban areas.
Heat Island Effect
In recent studies, Many scientists believe that UHI is mainly caused by urbanization. Exposing any surfaces such as hard surfaces, sand, water etc., to direct sunlight increases their temperature which consequently has an effect on regional weather, energy consumption and thermal comfort Rapid urbanization has caused an increase in the global temperature This has caused an elevated surface temperature as high as 70°C . The urban regions thus experience warmer air temperatures which contributes to the increased UHI.

Wide spread installation of Cool Tops can delay global warming (10 tons of CO2 offset by 100 m2 white roofing) (Menon et al. 2010; Akbari et al. 2009; Oleson et al. 2010)
Wide spread installation of Cool Tops can reduce UHI Effect;It has the overall potential to reduce city temperature by 2°C .(GCCA; LBNL)
Cool Tops improves air quality & health benefits (Rosenfeld et al. 1998; Akbari et al. 2001)
Installation of cool tops can reduce the temperature of the surrounding air and the rate of smog generation; resulting in a cozy setting; (Rosenfeld et al. 1998; Akbari et al. 2001)
Research & studies states the use of IR Reflective / High SRI paints & coatings reduce the surface temperatures, prevents heating of the roofs, walls and pavements hence controlling the heat transmittance indoors and thus reducing the indoor temperature. Cooler roofs & Cool Walls mean Longer Life of building envelopes with crack prevention & contribution to indoor cooling.
Cool Roof & Cool wall paints amends the roofs & walls just like new and provides energy conservation for temperature stability.
Increased Solar gain, heat stress, hot climatic conditions prevailing through most part of the year, expanding middle class, growing construction sector and increasing per capita income provokes the desperate requirement for thermal comfort and that has obvious visibility in the increased demand of purchase of “thermal comfort” in form of Air Conditioners – the most prominent positive electricity consumer!
When the ambient temperature is 450C the surface temperature of metal substrate is increased to 800 C & the temperature of cement surface is increased to 65-700 C. Application of Cool Tops reduces the metal surface temperature by 250 C & the cement surface temperature by 18-200C ; increasing a lot of thermal comfort indoors & reduction in HVAC load!
Cool surfaces thus can reduce UHI intensity and building cooling loads, lowering demand for electricity and greenhouse gas emissions from power plants. Various criteria and indices are used to assess the effectiveness of cool surfaces, including solar reflectance index (SRI) and variation in air temperatures. Materials with high values of reflectance and emittance would typically be considered cool and vice versa.
Cool surfaces, like cool roofs, cool walls, and cool pavements can help safeguard vulnerable groups such as underprivileged people in slums, children and the elderly from excessive indoor heat. According to a study by Lawrence Berkeley National Laboratory (LBNL) in the US and International IIIT-H, commercial buildings can annually save 13-14 kWhm^2 of energy by switching to cool-roofs.
Among all the components of Solar radiations transmitting to earth, almost 58 – 60% of the Solar radiations are of IR [ Infrared] Radiations, which get absorbed by the structures. This radiation is transformed into heat energy which ends up heating materials.
The temperature of The Roofs, Walls, Roads, Buildings, industrial sheds, tanks; all built structures (with less reflectivity & emissivity) exposed to Sun get elevated transmitting the heat indoors and emitting the heat of 60 to 75°C in the atmosphere.
Any material with high IR Reflective property will help to reflect the IR radiations coming from Sun hence prevent heating of the substrate- Roofs/ Walls/ Roads/ Non Roof Areas .
Any material with high IR Reflective property will help to reflect the IR radiations coming from Sun and STOP heating of the substrate- Roofs/ Walls/ Roads/ Non Roof Areas and reflect the radiations away from a building, reducing the surface temperatures, leading to reduction in heat ingress indoors and emission of heat in the atmosphere. A high thermal emittance also plays a role, particularly in climates that are warm and sunny. Thermal emittance is the ability to radiate absorbed, or non-reflected solar or heat energy. Together, these properties help any substrate to generate less heat and roofs stay up to 20–28°C cooler & walls stay up to 100 C cooler than conventional materials during peak summer weather. The measure for a good Cool Surface material is the better value of SRI, more than 100.

Sustainable Development Goal 13 is about climate action. The official mission statement of this goal is to "Take urgent action to combat climate change and its impacts". The decade between 2010 - 2019 was the warmest decade recorded in history. SDG 13 and SDG 7 on clean energy are closely related and complementary. The leading sources of the greenhouse gas savings that countries need to focus on in order to realize their commitments under the Paris Agreement are: switching fuels to renewable energy and enhancing end-use energy efficiency.

Energy conservation is crucial to fighting environmental changes, smog, and declining air quality caused by pollution and solar heat, and cool roofs can reduce unwanted solar heat gain, lower demand for electricity and greenhouse gas emissions, and decrease the need for air conditioning.
High SRI Paints
Cool Tops (Cool Roof System)- Cool roofs with high solar reflectance can reduce energy consumption and greenhouse gas emissions, especially in solar-dominant countries, by lowering building cooling loads and curbing pollution from power plants. By adopting cool Roofs one can raise the albedo (solar reflectance) of a building’s roof, reducing unwanted solar heat gain. This saves electricity and lowers peak power demand by decreasing the need for air conditioning.
Cool Wrap (Cool Wall Paints)- Cool Wrap is a sustainable wall paint that reflects infrared radiation to prevent wall heating. It contains no VOC and is free from harmful metals. Its cooling properties make it ideal for green projects.
Cool Top Xpress (Cool Pavements & Driveways)-Cool Top Xpress is a high Solar Reflective Index (SRI) coating designed for use on driveways, pavements, parking lots, and roads, with a high reflectivity that helps to counteract the effects of Urban Heat Islands.
Thermal Insulation Products
Insulmix Screed (Thermal Insulation for Roof)- Insulation reduces unwanted heat loss or gain and can decrease the energy demands of heating and cooling systems. Insulmix Screed is composed of special hydraulic binders with sealed expanded clay, expanded microspheres and minerals and a special additive for thermal insulation for the roof which helps achieve Energy Efficiency, Use of Recycled materials and Less Waste Generation. Insulmix Wall Plaster (Thermal Insulation for Wall)- Walls compose the maximum exposed area, thus thermal insulation of walls makes the most important component of the energy efficient buildings. The wall assembly consists of a system of components that fulfill the support, control, and finish function of the building envelope. Insulmix Wall Plaster is a mix of inorganic & organic material of insulation families along with incorporation of advanced materials to enhance the efficiency of insulation & workability.

A Cool Roof coatings consists of a binder (usually an organic compound or silicone compound) blended with pigments and other additives to provide two main benefits: protection of roof membranes for longer roof life cycles; and reflectivity of solar radiation, for lower air conditioning costs.
The main components of most Cool Roof coatings are the binder, pigment, water and reflective pigments. Water serves as a liquid carrier, which provides viscosity, allowing the pigment and binder to be spread on the roof as a thin coating. The majority of white coatings in use today are water-based coatings
An energy efficient , white, reflective, elastomeric coating manufactured by Panache can reflect up to 92% of visible light, keeping the roof surface much cooler than with aluminum, black, or non-reflective roofing materials. Lower temperatures mean less energy usage, and translate to money saved. Elastomeric roof coatings protect the roof substrate adding years to your roof, plus saves against costly tear-offs and re-roofing.
