Buildings use one-third of all energy and two-thirds of all electricity generated. Garco 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.
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.
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.
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 Garco’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.

The panels use a special foam insulation to provide superior R-values for greater thermal efficiency. The R-value is the unit of measurement of apparent thermal conductivity, or the resistance, of the flow of energy from warm to cold, and describes the rate that heat energy is transferred through materials. R-values are achieved by tiny air spaces that slow conductivity. Insulation with higher R-values will be more effective than those with lower R-values.
Insulated panels are ideal for temperature controlled building systems. They are thermally efficient, affordable and aesthetically pleasing. Insulated panels offered by Garco receive excellent test results for air leakage and water penetration through panel joints and meet the weathertightness requirements of most specifications.
Garco offers insulated panels that provide the benefit of being disassembled when they are no longer needed for a building. The disassembled metal panels can be recycled or reused to create the structure of a new metal building project. Maintaining 75% – 95% of existing walls, floors or the roof of a building provides one to two points when qualifying for LEED Certification.

Whether our customer is seeking to meet LEED, Green Globe or other certification requirements or simply wanting to improve the energy performance of their building, Garco offers solutions to reach many environmentally-friendly construction goals.
