Green Product SolutionsSteel Depot provides customers with a variety of green building options that help mitigate energy consumption and support overall green building efforts including: environmental, economic, and, health and community. As a leader in our industry, we are committed to the continuation of developing new green building opportunities and innovations for our customers.

The Green in Metal
Metal construction has green characteristics including recyclability and durability. In addition, strategically-designed metal construction projects contribute to a building’s improved energy efficiency, can reduce the amount of materials necessary for the building envelope and are often more cost effective than other non-metal construction materials.

roof 1Recyclability and Durability
Roof and wall panels, structural members and other building materials composed of steel are virtually 100% recyclable when removed, as opposed to many conventional, non-metal construction materials, which are taken to landfills. According to the American Iron and Steel Institute (AISI), steel is the most recycled material in North America, with an annual average recycling rate of 70 percent. Furthermore, new steel made with recycled material uses as little as 26% of the amount of energy required to manufacture steel from iron and other naturally extracted materials.

Metal roof and wall panels consist of a minimum of 25% percent recycled material and, with the addition of our structural members, our metal buildings can contain 30%-50% recycled material, depending on the project.

In addition to recyclability, metal roofs and wall panels can reduce waste due to their unmatched durability and resistance to fire, wind and insects. AISI reports that metal roofs last between 40 – 60 years and require less maintenance than other types of roofs.

roof 2Solar Reflectivity and the Solar Reflectance Index
Solar Reflectivity (SR), 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 total absorbance. ENERGY STAR requires an SR value of 0.25 or higher for steep slope (more than 2:12) roofing and SR value of .64 or higher for low slope (2:12 or less) roofing.

Solar Reflectance Index (SRI) is used to determine compliance with LEED requirements and is calculated according to ASTM E 1980 using values for reflectance and emissivity. Emissivity is a material’s ability to release absorbed energy. To meet LEED requirements, a roofing material must have an SRI value of 78 or higher for low slope (2:12 or less) roofing.

Cool Colors for Metal Roofing
Steel Depot offers cool paint colors for all of our metal roof panels. When used properly, considering the environment and the slope of the roof, a cool roof can reduce energy consumption, providing significant cost savings while helping to mitigate urban heat islands.

An urban heat island (UHIs) is an elevation of air temperatures in urban communities, relative to surrounding rural areas, caused when vegetation is replaced by large sections of pavement or other dark, non-reflective surfaces. Urban heat islands are believed to not only influence the temperature of the affected area but are also responsible for higher pollutants in the air.

Many of Steel Depot’s cool colors meet the reflectivity and emissivity performance levels required by LEED and ENERGY STAR to mitigate the cause of UHIs and energy consumption overall. Reflectivity is the deflection of solar energy from a surface. Roofs at 2:12 and greater have been proven to generate less of a heat island effect than lower-sloped roofs. Greater reflectivity abilities require less energy to cool a building.

Emissivity is the relative ability of a surface to emit heat by radiation. As with reflectivity, when a roof can effectively cool itself through radiative heat loss, it will reduce the amount of energy consumption for the building.

roof 3Insulated Metal Panels
Buildings using effective insulation systems have long-term impacts on the environment due to their ability to reduce energy consumption over an extended period. As a result, the reduction in energy used contributes to the reduction in energy costs. Steel Depot offers insulated metal panels that are ideal for numerous roof and wall applications, that when used as part of a strategically-designed green construction project, can improve the building’s energy efficiency, which is measured, in part, by what is known as an R-value.

Retrofit Roofing
For building owners and architects looking to achieve LEED Certification on an existing building, Steel Depot’s retrofit roofing system can help. It uses light-gauge framing in combination with our metal roofing panels. When applied over an existing roof with a specified slope, a retrofit system delivers an aesthetically pleasing effect, while improving SR values and providing water runoff solutions. In addition, if the existing roof materials remain, they won’t become waste added to landfills, with many serving as added insulation. NCI’s retrofit framing system is ideally suited for a wide-range of substrates including steel, wood or concrete. The retrofitting technique can also work for new construction as an economical and competitive alternative to prefabricated truss construction.
