Measurement of solar reflectance

refl
In condition of strong solar radiation, the heat load to be discharged by means of air conditioning systems is closely related to the solar reflectance of opaque building elements. The knowledge of solar reflectance of roofing surfaces, walls and shading elements is a fundamental requirement for the correct design of efficient and comfortable building systems.

Tests of solar reflectance are conduced according to two different standards:

- ASTM E 903, using a UV-Vis-NIR spectrophotometer with 150 mm integrating sphere. Test is accredited ISO 17025.

- ASTM C 1549, using a D&S solar reflectometer. Test is accredited ISO 17025.

 

EELab works in close partnership with other lab of the Department of Engineering "Enzo Ferrari" of the University of Modena and Reggio Emilia on the development of innovative materials with high solar reflectance, to be used in building and automotive applications.
