Naturpiedra Jbernardos currently employs more than 100 people directly, a number which shows an upward tendency.<\/p><p align=\"justify\">&#8211; Regarding the environmental aspect, the entity Naturpiedra Jbernardos complies with all the legal requirements which are imposed upon it, as a company exploiting and working with a natural resource, by the demanding European environmental legislation. Thus, the quarry\u2019s tailings are processed in controlled debris management spots, the slurries from slate-cutting are treated in appropriate spaces, the residual water resulting from the quarry\u2019s drainage is recycled, the oils from the vehicle\u2019s engines and machinery are taken to recycling points, etc. In order to guarantee its compliance with this legislation, Naturpiedra Jbernardos keeps the required restoration plans up-to-date, as well as the corresponding mandatory permits.<\/p><p>\u00a0<\/p><p align=\"justify\"><b><br \/>ENERGY EFFICIENCY<\/b><\/p><p align=\"justify\"><span style=\"font-size: 1rem;\">The use of energy-efficient materials in the construction of buildings requires a meticulous selection in order to optimise costs and maintain an adequate and comfortable temperature for the inhabitants of large cities, where temperatures tend to be quite high.<\/span><\/p><p align=\"justify\">It has been recognised and demonstrated that the temperature in urban areas is significantly higher than in neighbouring suburban and rural areas. This phenomenon known as \u201curban heat island\u201d increases the surface temperature of buildings, leading to an temperature rise of up to 3\u00b0C more in comparison with suburban and rural areas.<\/p><p align=\"justify\">In this context, the demand for energy to cool down buildings and thus reach a comfortable temperature clearly rises too.

The scientific definitions of these two terms are as follows.<\/p><p align=\"justify\">&#8211; Solar Reflectivity (R) refers to the ability of a material to reflect solar energy from its surface back into the atmosphere.<\/p><p align=\"justify\">&#8211; Infrared emittance or emissivity (\u03b5) is the proportion of \u201cinfrared radiation\u201d shed by a material\u2019s surface due to the temperature which the material reaches in a given environment.<\/p><p align=\"justify\">Both values are measured on a scale from 0 to<\/p><p align=\"justify\">The closer they are to 1, the colder the surface can remain when exposed to the sun.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<section class=\"elementor-section elementor-top-section elementor-element elementor-element-44b4ef7 elementor-section-boxed elementor-section-height-default elementor-section-height-default\" data-id=\"44b4ef7\" data-element_type=\"section\" data-e-type=\"section\">\n\t\t\t\t\t\t<div class=\"elementor-container elementor-column-gap-default\">\n\t\t\t\t\t<div class=\"elementor-column elementor-col-100 elementor-top-column elementor-element elementor-element-ddd5dbb\" data-id=\"ddd5dbb\" data-element_type=\"column\" data-e-type=\"column\">\n\t\t\t<div class=\"elementor-widget-wrap elementor-element-populated\">\n\t\t\t\t\t\t<div class=\"elementor-element elementor-element-27346f7 elementor-widget elementor-widget-image\" data-id=\"27346f7\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"image.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t\t\t\t<figure class=\"wp-caption\">\n\t\t\t\t\t\t\t\t\t\t<img decoding=\"async\" width=\"1500\" height=\"680\" src=\"https:\/\/naturpiedra.com\/es\/wp-content\/uploads\/2023\/01\/Sostenibilidad-y-Eficiencia-Energetica-naturpiedra-2-1.jpg\" class=\"attachment-full size-full wp-image-41233\" alt=\"\" \/>\t\t\t\t\t\t\t\t\t\t\t<figcaption class=\"widget-image-caption wp-caption-text\">Picture II-11.
