Roofing systems from Sika are ideally suited to fulfill the Congressional requirements of U.S. government procurement agencies — under established directives to incorporate energy efficiency and sustainability into all facets of building construction.
Sika Sarnafil Roofing Solutions are Compliant with:
- Department of Defense Unified Facilities Criteria
- U.S. Postal Service Building Design Standards
- EnergyStar, LEED & Green Globes
Buildings consume 40 percent of primary energy and 72 percent of the electricity in the U.S. Total energy expenditures for federal government facilities alone were $4.26 billion in 2005. A large percentage of that energy usage is to cool buildings. Even in colder climates, many buildings are air conditioned year- round due to internal heat.
Greenhouse Gas, Pollution, and Urban Heat Island Mitigation
Carbon dioxide emissions are a major contributor to global warming. Buildings account for 35 percent of the emissions in the U.S. Replacing dark colored roofs with reflective, light colored roofs on 80 percent of commercial buildings air conditioned roof areas could reduce the carbon dioxide emissions by 6.23 metric tons per year.
Sika EnergySmart Roof helps minimize the urban heat island effect caused in large part by a high density of dark colored surfaces in and urban environment.
Outer space is not the only area where NASA does research. In fact, the Sustainability Base at NASA Ames Research Center in Moffett Field, California is testament to research NASA is doing right here on earth. Considered to be the “greenest” federal building in existence, the 50,000-square-foot, two-story, lunar-shaped building is designed to be “a workplace, a showcase for NASA technology and a living prototype for future buildings,” according to NASA. “It is NASA’s latest mission on earth.
Recycling reduces the environmental impacts of producing new materials at the beginning of the life cycle and the burden on landfills at the end.
Sika recycles more that 4 million pounds of membrane trimmings annually. In addition, a post-consumer recycling program allows building owners to recycle vinyl roofs at the end of their useful life. Millions of square feet of old roofing membrane have been recycled into new roofing products.
Post consumer recycling, the recycling of roof membranes at the end of their useful life, is an opportunity to divert construction debris from the waste stream. The technology exists to recycle the material but historically the lack of a need in the market has prevented the establishment of a viable infrastructure to allow recycling. The sustainability movement along with the advent of landfill restrictions on construction waste in cities such as Chicago and Boston and the increase in waste disposal fees has begun to create the conditions to make recycling old roofs a reality.
The Solar Electric Roofing System integrates reflective EnergySmart Roof which improves the building’s energy efficiency and reduces utility bills. Building owners save money, especially during peak demand periods, and may get credit for feeding excess solar power into the local electrical grid.
Durability and Longevity
Sika Sarnafil roofs last for decades. Independent scientific research organizations have evaluated and documented this performance:
An independent panel consisting of industry consultants and government-related organizations from the U.S. and Canada studied the service life of roofing membranes. The group issued an interim report in 2005 indicating that Sika's composite score was excellent, and that the company’s membranes performed well in virtually all categories.
Vinyl by its basic formulation is very fire resistant. This is why PVC is utilized in many critical applications such as electrical wire jackets. One of the strengths of PVC roofing membranes is the ability to self extinguish and resist spread of flame. Sika Sarnafil’s roofing membranes have been widely tested and meet fire code requirements in over 20 countries worldwide.
The eight-story building is home to the NFPA (National Fire Protection Agency), where much of the research for the United States is conducted and standards created.
Recognizing the importance of fire and other performance properties of the roof system, Russo and Spaulding & Slye selected a Sika Sarnafil Class A rated roof assembly. Russo specified the existing roof system to be removed down to the steel deck.
The steel deck was replaced where it had deteriorated. Three inches of Sarnatherm insulation was secured to the steel deck. Sika Sarnafil’s 60 mil G410 membrane was adhered to the insulation.
Examples of Sika Roofing projects:
With the California budget crisis looming over their heads, the last thing California lawmakers needed was an inefficient, money-wasting new roof on the California State Capitol building. Fortunately, the Sika Sarnafil roof recently installed on the historic Sacramento landmark is a proven, sustainable system that will not only offer energy savings, but will also provide an excellent return on investment over the life of the roof.
At the largest point, the Cantano Ferry Boat Terminal stretches out 240 by 312 feet, making it the world's largest ferry boat terminal station. It features a large barrel roof and main entry terminal with low slope deck to allow for 250 solar panels. Originally a metal roof was considered for the new building, but due to the high winds and continuous salt spray it was ruled out in favor of the Sarnafil Decor system in patina green.
