How your Business Can Become More Environmentally Sustainable, and Reduce Carbon Emissions with a Smart and Environmentally Responsible Roof Coating.

 ~ Cool Down Your Roof and Stop Using So Much Air Conditioning ~

If you are the person responsible for managing your company’s carbon footprint, and/or are interested in becoming more efficient and sustainable, then you need to read this ~
The heat insulation industry refers to a roof coatings reflectivity as a ‘TSR’. (Total Solar Reflectivity). 
If one merely uses a very light roof coating, around 50% of TSR can be achieved for a short time. A new bright white roof surface can originally reflect up to 65% TSR, and make you cooler at first.
Before long, such as normally within the first two years of the coatings life, it will begin to break down (The white substance that soon wipes off as the solvents and polyester break down*) and the roof soon becomes non reflective again, loosing up to 40% of its original TSR. (*Not so good for water collection either)
A Bare Roof or Worn Roof Coating in Any Colour is Absorbing around 90% of Radiant Heat, Reflecting Only Around 10%.

A Roof Treated in a Heat Reflective Coating Will Only Absorb 10% as it will Reflect Around 90% of Radiant Heat

That is a Reduction in Roof Surface Temprature of around 40 degrees on a hot sunny day. This should reduce your air conditioning energy usage by more than 50% in most circumstances
Heat Reflective Coatings are Guaranteed to Keep Reflecting and Saving Energy for a Minimum 10 Years

A roof left untreated is expanding in the sun and contracting in evening; this is causing ‘Thermal Shock’ http://en.wikipedia.org/wiki/Thermal_shock and putting the roof and its coating under even more stress.
This roof although light or white will soon reflect only around 10 - 20%. So the balance of heat is absorbed into the roof structure for conduction to carry the heat into the home and its occupants.
If this had been coated with a darker colour, it would loose so much TSR that it will be reflecting only 3 – 5 % and absorbing up 97% of radiant heat. Situations like this can result in the roofs surface temperature reaching up to almost 100 degrees on a sunny day. 
Many buildings in this situation are continually running air conditioning units that are trying to combat the constant heat source coming from the roof. Even wool insulation in the ceiling will then heat up and hold the heat in the building for hours.
How Heat Reflective Insulating Roof Paint Will Keep You Cooler Without Wasting Energy 
Using heat reflective roof coatings, you can achieve up to 90% reflectivity.
Of all the methods of power saving available, Heat Reflective Coatings are is one simplest to implement, and is probably the least capital intensive. It has the ability to make a significant reduction to our energy bill, and the associated reduction in greenhouse gas, without lifestyle reductions, which would be resisted by the population.

Because we live in a relatively hot climate, one of our largest demands for energy is that of air conditioning. This particularly applies in our work place and in large public buildings such as shopping centres. Significant power savings can therefore be made by making more efficient use of air conditioning. Reducing the amount of heat energy entering a building, which must be removed by the air conditioning plant, can provide this improvement.

Heat Reflective Coatings work by reflecting solar energy from the surface to which it is applied. Long term testing has shown that for a galvanised iron or colourbond steel roof, then application of HRC to the exterior surface will reduce the heat load to be removed by the air conditioner, by reducing the surface temperature of the roof as much as 40oC.

Power savings for a typical building with a roof area of 10,000 square metres could be expected to be 100,000 Kwh per year or more. This would give a reduction in greenhouse gas emissions for this building alone, of about 100 tonnes per annum.

Heat Reflective Coatings require little energy in production and has the economic benefit of a payback period of 4 to 5 years. In addition the solution is here now, it does not required any special technology to apply, and cost and environmental benefits start immediately with minimal ongoing cost and maintenance demands.

Tests have shown that the surface temperature of galvanised iron is reduced by over 40°C resulting in a drop of up to 20°C within a building, creating comfortable internal conditions.
