Kronos Porcelain Pavers are produced in the U.S., the manufacturing plants are located in Tennessee.

The factory is member of the U.S. Green Building Council, which is an organization that
promotes buildings that are environmentally responsible, profitable and healthy places to live and work.

In accordance with LEED Rating System and UNI EN ISO 14021:2016 Enviromental
labels and declarations – (Type II enviromental labelling), declares that:

Kronos USA tiles are produced in manufacturing plans which have got the prestigious ecological mark ECOLABEL (EU Regulation 2002/272/EC). These plants vant the environmental management systems compliant to ISO 14001:2004 and EMAS (European Council Regulation 761/2001). These environmental standards guarantee excellence in terms of:
  • safeguard of the environment;
  • continuous improvement of the environmental performances of Kronos USA products and manufacturing sites;
  • healthcare of Kronos Usa workers and customers.

SS SUSTAINABLE SITES: HEAT ISLAND EFFECT

THE HEAT ISLAND EFFECT

Urban areas are usually warmer than their rural surroundings, due to a phenomenon known as the “heat island effect.”

Cities development involves the decrease of vegetation areas in favor of the urban backgrounds, where the surfaces are paved or covered with buildings, the change in ground cover results in less shade and moisture to keep urban areas cool. Built-up areas tend to evaporate less water, which contributes to elevate surface and air temperatures. Several properties of urban materials, in particular solar reflectance, thermal emissivity, and heat capacity, also influence the development of urban heat islands, as they determine how the sun’s energy is reflected, emitted, and absorbed.

Heat islands can affect communities by increasing summertime peak energy
demand, air conditioning costs, air pollution and greenhouse gas emissions, as
well as heat-related illness and mortality, and water quality. 

Lawrence Berkley National Laboratories (LBNL), which has performed extensive research on the heat island effect in urban areas, has established that the probability of smog creation rises 5 percent for each one-half degree increase above 70°F. While LBNL has concluded that reduced vegetation accounts for the largest percentage of urban heat islands at 56 percent, dark roofing surfaces run a strong second at 38 percent. The USGBC has addressed the heat island effect in regard to both roofing surfaces and other large, typically paved areas in its LEED guidelines.

WHAT IS THE SOLAR REFLECTANCE INDEX?

In October 2005, the USGBC released new guidelines for LEED credits.
The New Construction Version 2.2 revised the values required for mitigating the heat island effect.
The guidelines are now based on the Solar Reflectance Index (SRI) of specified materials as calculated by ASTM E 1980.

EMITTANCE –
The emittance of a material refers to its ability to release absorbed heat. 
Scientists use a number between 0 and 1 to express emittance.
With the exception of metals, most construction materials have emittances above 0.85.

SOLAR REFLECTANCE –
Also known as albedo, is the ratio of the amount of solar radiation reflected from a surface to the total amount reaching that surface (which includes visible and ultraviolet light and infrared radiation).

SOLAR REFLECTANCE INDEX (SRI) –
SRI is a value that incorporates both solar reflectance and emittance in a single value to represent a material’s temperature in the sun. SRI quantify es how hot a surface would get relative to standard black and standard white surfaces.
It is calculated using equations based on previously measured values of solar reflectance and emittance as laid out in the American Society for Testing and Materials Standard E 1980.

WHAT SRI VALUES DO BUILDING MATERIALS NEED FOR LEED?

As shown in Table 1, the minimum SRI for cool roofing has increased in the newer LEED v4. In the earlier LEED 2009 requirements, cool roofing did not consider age. SRI as an option for qualification.
Projects seeking LEED v4 have the option of qualifying using either initial SRI or by obtaining the 3-year aged SRI value.

The impact of hardscape such as roads, sidewalks, courtyards, and parking lots is an important element in earning the Heat Island reduction credit.
Table 2 shows the requirements for hardscape and shade providing architectural devices and structures. In LEED version 4, paving materials require documentation for Solar Reflectance only, not the SRI asked for in LEED 2009.
