As people become more aware of the environment, the requirements of “green” projects are building.Therefore, it is valuable for the decoration of entrepreneurs to take concrete steps on LEED ratings, and know the consequences for the temperature of concrete.
The Leadership in Energy and Environmental (LEED) is an organization created to support public safety, structures more environmentally concerned.They operate on a points system that are assigned when a customer meets certain environmental criteria. If a client is interested in earning LEED points, the concrete is cooler than a way to acquire them.
Cool the solar surface with a refractive index of the surface, or SIR-determined value. SRI is a material, the measured temperature and heat generation in the reflection. They are calculated on a scale of zero to one, with more thought. Reflection is the ability of a surface to reflect sunlight, while the emittance, and a surface radiates heat to space is defined. SRI value is important in decorative concrete, as a prerequisite for LEED green concrete surface has an SRI of 29 or higher.
Manufacturers should be interested in the benefits of colder surfaces, because they show a series of studies that contribute to the treated surface urban heat effect Iceland. The UHI, as defined by the Agency U. S. Environmental Protection, is a considerable increase in the temperature of urban air temperatures basically the replacement of vegetation with buildings, roads and other infrastructure that absorbs heat. The heat island effect can lead to significant temperature differences between rural and urban areas.
In other words, as the sun comes into contact with objects such as buildings or roads, the radiation is absorbed and creates heat. Temperatures can reach unacceptable when heated objects are unable to sunlight is reflected. As a result, the energy required to cool the area. Obviously, excessive heat can affect the health, safety and comfort of residents. Fortunately, the surface temperature of materials, particularly concrete surfaces can be reduced to a few different ways.
Although concrete is a natural substance can cool the temperature of other treatments or ornaments, or low. For instance: brighter colors, durable sealants and coatings, concrete / irregular surface texture, permeability, maintenance and even decorative accessories such as glass. IR-reflective technology also allows you to control the heat on concrete surfaces.
The following is an excerpt from the Portland Cement Association:
“Concrete surfaces can be a LEED certification for new construction and major renovations (LEED-NC Version 2.2) credits through Sustainable Sites Credit 7.1: Iceland roof .. the heat is not the intent of this credit to reduce the effect of heat island, the intention can be achieved if the materials that remain fresh in the sun at least half the earth’s surface the roof is not waterproof, such as roads, sidewalks, patios and parking lots are used. ”
Technology, a product to maximize total solar reflectance can be a concrete surface to absorb an uncomfortable amount to prevent the sun’s rays.Maximizing solar reflection, the products are also now available in dark colors, for a homeowner to build with the environment in mind while still capable of the appearance they desire. With infrared reflective technology in concrete surfaces can reduce an IRS classification, and contribute to a clientele of LEED points.
