Floor Materials Solar Reflectance

Concrete as Solar Reflectance Material - Portland Cement Association Concrete does a very good job of reflecting solar energy. That is the finding from a Portland Cement Association (PCA) study which measured the solar reflectance index (SRI) of 45 concrete mixes. Lighter colored materials (such as concrete) generally have a higher solar reflectance. They reflect heat from the sun and do...

Solar Reflectance Values of Concrete - Portland Cement Association This solar reflectance value results in an 5Rl of about 37. All of the concrete mixtures studied in this report, regardless of constituents, would therefore meet the LEEO-NC 55 Credit 7.1 paving material requirement or the LEEO-NC 55 Credit 7.2 steep-sloped. ,a ld e. Husqvarna Hiperfloor is a revolutionary flooring concept for...

Solar Reflectance - Portland Cement Association than any other constituent material. The solar reflectance of the supplementary cementitious material had the second greatest effect. REFERENCE.

Solar Reflectivity (R) & Solar Reflectance Index (SRI) by Color ... Solar Reflectivity (R) &. Solar Reflectance Index (SRI) by Color. Solar reflectivity or reflectance is the ability of a material to reflect solar energy from its surface back into the atmosphere. The SR value is a number from 0 to 1.0. A value of 0 indicates that the material absorbs all solar energy and a value of 1.0 indicates total...

Urban Heat Island Reduction, SRI - Concrete Thinker Urban heat islands are primarily attributed to horizontal surfaces such as roofs and pavements that absorb solar radiation. In this context, pavements include roads, parking lots, driveways and sidewalks. Where paved surfaces are required, materials with higher solar reflectance (albedo), such as concrete, will reduce the...

Green in Practice 111 - Solar Reflectance of Concretes for ... One point can be earned by using paving materials with a solar reflectance index of at least 29 for 50% of the site hardscape (including roads, sidewalks, courtyards, and parking lots). This is “Sustainable Sites Credit 7.1: Heat Island Effect: Non-Roof”. Another point can be earned by using roofing materials with a solar...

CASE STUDY: Natural Stone Solar Reflectance Index and the ... Jul 17, 2009 ... absorption and release of the sun's energy by buildings and other manmade structures. Heat islands are most common in urban areas where surfaces are comprised of synthetic materials. In particular, roofing and pavement absorb heat from the sun, especially when their capability to reflect solar radiation...

High-Reflectance Technology on Building Fa?ades - MDPI Aug 10, 2016 ... Retroreflective material was considered for use on building fa?ades below the third floor in order to avoid impacts on pedestrians from the reflection of solar radiation. Keywords: building fa?ade; pedestrian comfort; high-reflectance technology. 1. Introduction. As a measure to counter the urban heat island...

Building materials with high solar reflectance - Centro Ceramico For many years Centro Ceramico has been involved in the design, development and characterization of building materials with high Solar Reflectance. ... SRI values, reflectance spectra and thermal emissivity values of several flooring and covering materials including ceramic tiles, clay bricks, natural stones and concretes.
