MACOMA Environmental Technologies is committed to slowing down global warming by reducing greenhouse gasses and protecting human health through economical, reflective nano-paint  and photocatalytic technology.

MACOMA Cool Roof & Cool Façades, reflects heat, reduces energy use by up to 40%, resulting in lower power bills, decreases greenhouse gas emissions and more.  A 1000 sq. ft. (100 square meter) roof treated with our technology offsets 28 tons of CO2.

MACOMA Cool Roof is designed to reflect more sunlight than a conventional roof, while absorbing less solar energy. This reduces the temperature of the building. Conventional roofs can reach temperatures much higher than the ambient temperature, for example 65°C or more, which heats the interior of the building or house. MACOMA Cool Roof prevents the roof from heating up while maintaining the ambient temperature, it can even be 2°C or 3°C below the ambient temperature. MACOMA COOL ROOF has a high “thermal emissivity”: the ability to shed heat by emitting “thermal infrared” radiation. SRI 98 Solar Reflectance 0.79 Thermal Emission 0.88

Benefits of MACOMA Cool Roofs & Cool Façades

A Cool Roof & Cool Façade can benefit a building and its occupants by:

  • Reducing energy bills by decreasing air conditioning needs
  • Improving indoor comfort for spaces that are not air conditioned, such as garages or covered patios
  • Decreasing roof temperature, which may extend roof service life.

Beyond the building itself, cool roofs can also benefit the environment, especially when many buildings in a community have them. Cool roofs can:

  • Reduce local air temperatures (sometimes referred to as the urban heat island effect)
  • Lower peak electricity demand, which can help prevent power outages
  • Reduce power plant emissions, including carbon dioxide, sulfur dioxide, nitrous oxides, and mercury, by reducing cooling energy use in buildings. 

MACOMA Cool Roof
Reduces Urban Heat Island

An urban heat island occurs when a city experiences much warmer temperatures than nearby rural areas. The difference in temperature between urban and less-developed rural areas has to do with how well the surfaces in each environment absorb and hold heat.

Numerous universities, government agencies, and international institutions for the reduction of global warming have verified and agree that refractive roofs and pavements offset carbon dioxide CO2 emissions.

It is calculated that 100m2 of refractive ceiling offsets 28 Tons of CO2, which represents 28 Tons of carbon credits, which can be traded in the international market.

1 m2 of surface area per 0.01 reduces long-term global temperature by around 3 10 15 K, which offsets between 6.5 and 7.5 kg of CO2 emissions, (Hashem Akbari et al 2012 Environ. Res .Lett.7 024004)
