Determination of Solar Reflectance Near Ambient Temperature Using a Portable Solar Reflectometer: ASTM C1549: A technique for determining the solar reflectance of flat opaque materials in a laboratory or in the field using a portable solar reflectometer. This test method does not supplant Test Method E903, which is the standard.
Reduce heat islands by understanding your materials. CTLGroup performs solar reflectance index testing SRI thermal testing in general accordance with ASTM C 1549, Solar Reflectance Near Ambient Temperature Using a Portable Solar Reflectometer, and we calculate the solar reflectance index according to ASTM E 1980, Standard Practice for Calculating Solar Reflectance Index of
SOLAR REFLECTANCE Index. Solar Reflectance Index SRI is a composite measure that combines surfaces solar reflectance and emittance. Essentially, the SRI is an indicator of how well a surface reflects reflectance and release absorbed solar radiation emittance . The lower the SRI, the hotter a material is likely to become in the sunlight.
Solar and Light Reflectivity Values for Alucobond Colours and Finishes Solar Reflectivity The environmental classification system LEED askes for the solar reflectance index SRI particularly for roofs. The colour is the most important aspect for solar reflectance and SRI. The SRI is calculated according ASTM E1980-01, which describes the
Solar Light Company, Inc. provides Visible Spectral Reflectance Testing Services, covering the 400-700nm range with 10nm intervals. As a means of assessing the changes of a material under the action of accelerated light exposure, we employ our Hunter spectrophotometer to measure the Spectral Reflectance, or color changes.
The age of the specimens at the time of testing is unknown. The specimens were approximately 4-in. by 8-in. by 2¼-in. brick samples. The top surface of each specimen is slightly rough and textured. On February 13, 2014, the solar reflectance of the top surface of each of the specimens was measured in three locations.
The subcommittee has also undertaken the development of a standard practice for calculating a solar reectance index SRI of horizontal and low-sloped surfaces. test method for measuring solar reectance of horizontal 10 a.m. and 2 p.m. ASTM Standards for Measuring Solar Reflectance and Infrared Emittance of Construction Materials

solar reflectance index SRI and the surface temperature of the sample was calculated following the procedure in ASTM E1980. Results The results only refer to the object specified in this document. Spectral reflectance: See diagrams in appendix 1.
Solar Reflectance Index SRI In relation to Pervious Concrete 29 or greater = Acceptance level for achieving SRI levels acceptable for LEED Pervious because of its uneven surface with hills and valleys creates shadows. This makes it appear somewhat darker than traditional concrete pavement.
These can be performed for space applications as well as terrestrial applications such as obtaining the Solar Reflectance Index SRI toward LEED coatings and materials and instruments to measure their properties has necessarily required laboratory expertise in the measurement and testing of the properties of coated and uncoated surfaces.
This report presents the results of solar reflectance testing on 135 concrete specimens from 45 concrete mixes, representing a broad range of concretes. The purpose of this testing is to determine which combinations of concrete constituents will meet the solar reflectance index
The solar reflectance index SRI is a measure of the constructed surfaces ability to reflect solar heat, as shown by a small temperature rise. It is defined so that a standard black surface reflectance 0.05, emittance 0.90 is 0 and a standard white surface reflectance 0.80, emittance 0.90 is 100.

Examples of Film Measurements. Solar transmittance measurement software was used to calculate the performance test items. This software supports the calculation of visible light transmittance, UV transmittance, solar transmittance, and solar reflectance for flat glass according to JIS R3106. For these tests, the calculations prescribed in JIS A5759
These points can be earned by specifying materials with a Solar Reflective Index SRI of at least 29 when measured according to ASTM E903 or ASTM C1549. The actual SRI value of the concrete or structure made with Davis Colors can vary significantly from these values.
