About SACSA

On the 6th February 2014 the South African Cool Surfaces Association (SACSA) was established. The formation of the Association is as a result of a conference in May 2013 organized by the South African Department of Energy, United States Department of Energy and SANEDI who invited participation in the conference for the Cool Roofs and Pavements Working Group of the Global Superior Energy Performance Partnership (GSEP) – an initiative of the Clean Energy Ministerial (CEM) and the International Partnership for Energy Efficiency Cooperation (IPEEC).

High-level government officials, regional decision-makers, industry representatives, green building and sustainability experts and others convened to:

Introduce the concept of Cool Surfaces

Share the best practices and experiences of global leaders in sustainability, and forge new relationships and partnerships to support initiatives to bolster resiliency and sustainability through cooler buildings, communities, cities and nations. This conference led to the formation of SACSA.

SACSA is a non-profit organization to implement and communicate an accurate radiative energy performance rating systems for roof and other surfaces, support research, and serve as an educational resource for information on roofing.

The South African Cool Surfaces Association (SACSA) was created to develop accurate and credible methods for evaluating and labeling the solar reflectance and thermal emittance (radiative properties) of surfaces, including roofing products and to disseminate the information to all interested parties.


Vision & Mission

SACSA is a non-profit organization for the following purposes:

To implement and communicate fair and accurate, credible radiative energy performance rating systems for roofs and surfaces

To support research into energy related radiative properties of roofing surfaces, including durability of those properties

To provide education and objective support to parties interested in understanding and comparing various roofing options

Technical Information

A cool roof reflects and emits the sun’s energy (radiation) as light back to the sky instead of allowing it to enter the building below as heat. In many climate zones, a cool roof can substantially reduce the cooling load of the building, providing several direct benefits to the building owner and occupants.

If a building does not have air conditioning, this keeps the building cooler and a more constant temperature. If a building has air conditioning, the equipment does not have to work as hard.

Standards & Testing

Standards used by SACSA

ASTM C1549 – Standard Test Method for Determination of Solar Reflectance Near Ambient Temperature Using a Portable Solar Reflectometer
ASTM C1371 – Standard Test Method for Determination of Emittance of Materials Near Room Temperature Using Portable Emissions Meters
ASTM E903 – Standard Test Method for Solar Absorbance, Reflectance, and Transmittance of Materials Using Integrating Spheres
ASTM E1918 – Standard Test Method for Measuring Solar Reflectance of Horizontal and Low-Sloped Surfaces in the Field
ASTM E1980 – Standard Practice for Calculating Solar Reflectance Index of Horizontal and Low-Sloped Opaque Surfaces

SABS Testing

"The newly established Building Envelope Testing Services (BETS) at the SABS is in the process of procuring equipment to test the performance of cool roofs and surfaces in order to assist with the rating of products. “

Product Directory

Product rating, labeling & certified product directory:

Product Rating:

At the core of SACSA is its Product Rating Program, in which roofing manufacturers can label various roof surface products with radiative property values rated under a strict program administered by SACSA and SAFIERA (South African Fenestration and Insulation Energy Rating Authority)

SACSA does not set a minimum definition for “cool”; the Association simply lists the measured radiative property values on our Directory. Any roofing product can be tested as long as it is in compliance with the product rating manual. A product’s placement on the Directory does not mean that the product is “cool” as defined by any particular code body or program

All radiative property testing is conducted by accredited testing laboratories. The SABS is in the process of procuring equipment to become an Accredited Testing Laboratory
