How Much Cooler Will My Building Be

The use of Energy Star heat reflective coatings on the external roof and walls of a property is guaranteed to increase the buildings reflectivity to sola induced heat and reduce the absorbed heat in the building envelope.  In some circumstances and climatic conditions, substrate temperatures can be reduced by as much as 50%.  

To accurately state the temperature reduction that can be achieved using Energy Star is however, difficult to state as every building is different and there are many factors that will effect the actual reduction of internal temperature such as; existing insulation levels, Australian climate zone, glazing, shading, the buildings orientation and external fabric.

However, for the assistance of our users we are able to accurately state substrate temperature reductions from tests conducted to ASTM E 1980-01 which is an international standard for the testing of thermally regulated paints and coatings.

The chart in the Sub-Menu on the right compares standard colours to identical colours in Astec Energy Star and provides an example of plain galvanized metal under the same test conditions.
