Propiedades ópticas de enredaderas en fachadas vegetadas

Abstract

In this work the optical properties of the vines Pentalinon luteum and Clitoria ternatea native of tropical America whose qualities are reported as: adaptability to hostile environment, low water requirement, broad foliage and aesthetic appearance, they can be used in the green facades to cover buildings. Both species function as attenuating radiation for wavelengths in the range 700 - 1000 nm (near infrared); in this same region the species pentalinon luteum, has standardized values of 0.54 - 0.80. In the visible region of the electromagnetic spectrum, in the length equal to 550 nanometers the diffuse reflectance was 0.22 to 0.48 and absorbance of 0.51 to 0.76. The experimental development was carried out following the life cycle of leaves, classifying them by their maturity in three sizes: young leaves, mature leaves and senescent leaves.
