About Cool Surfaces

The Cool Surfaces Project began as a collaboration between the South African and United States of America’s respective Departments of Energy under the Clean Energy Ministerial. The Cool Surfaces Project is the response to South Africa’s need for an energy passive, low cost, low maintenance cooling technology for buildings.

South Africa relies on coal for about 90% of its energy input, resulting in a large amount of carbon dioxide emissions. This pollution, concentrated around the power ENERGY EFFICIENCY ENERGY EFFICIENCY stations mainly in the Mpumalanga area, is not caused by the power stations alone but by all South Africans, as they are generating the pollution through their excessive use of coal-based energy. These emissions contribute to the changing climate patterns we are now seeing develop in South Africa – climate change is a reality today, not some time in the distant future. Every kilogram of coal burnt releases approximately one kilogram of carbon dioxide.

PARTNERS AND FUNDING

Initially the Cool Surfaces project was a cost share initiative between the USA DOE and RSA DOE that contributed to kick starting it. SANEDI is in partnership with the Department of Public Works and the National Development Agency, is funding the project. Two SANEDI programmes (Energy Efficiency Programme and Working for Energy) are collaborating to implement Cool Surfaces.

BENEFITS OF COOL SURFACES

Cooler surface temperatures help the roof and the equipment on it last much longer.

  • Cool roofs allow less heat into the building, making un-airconditioned homes, warehouses and other buildings much cooler.
  • In cities, cooling effects vary from city to city, but studies indicate a consistent pattern of cooling potential from between 2 and 4°C.
    Whitening 100m2 of roofing cancels the warming effect of 10 tons of CO2 emissions (or 0.6 tons per year for the life of the roof).

Globally cancels 500 medium- sized coal power plants’ worth of greenhouse gas emissions – more than CFL deployment. It is an excellent offset measure.

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).

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

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.

“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

    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

    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 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
