#3 LEED – Green Roofing
To prevent health hazards, like mold and mildew, keeping your family safe
A new roof, adequately designed and ordered directly from the factory, will reduce costs while building a SIP Panel Building Envelope.
Once shipped, it can be installed by a local roof professional.
The roof designed will provide a strong seal against the elements and lower heating/cooling costs.
New roofs help prevent health hazards, like mold and mildew, keeping a family safe.
HVAC efficiency: A new Spartan Roof ordered from the factory allows HVAC systems to work more efficiently, saving money on monthly energy bills. One can expect to save about 44% on utility bills on average, which adds up significantly during the winter and summer months.
Plus, it increases one’s curb appeal and the value of one’s home!
It used to be that these benefits don’t come without a big cost — but not anymore since Spartan can buy direct from MFG facilities of galvanized roof products. And if you choose a standard size, these items will be automatically fitted to your SIP construction choices.
Reducing Urban Heat Islands
Cool roofing can help address the problem of heat islands, which results in part from the combined heat of numerous individual hot roofs in a city or suburb. Cool roofing products are made of highly reflective and emissive materials that can remain approximately 50 to 60°F (28-33°C) cooler than traditional materials during peak summer weather. Building owners and roofing contractors have used these types of cool roofing products for more than 20 years.
Normalized Solar Intensity
Understanding how cool roofing works requires knowing how solar energy heats roofing materials and how the properties of roofing materials can contribute to warming. This section explains solar energy, the properties of solar reflectance and thermal emittance, and the combined temperature effect of these two properties working together.
In hot climates solar energy makes the attic and roof area extremley hot and wastes huge HVAC resources. In some instances 150 degrees. Needs to be cooled by your HVAC system.
The California Energy Commission has sponsored the “Cool Colors Project,” under which LBNL and Oak Ridge National Laboratory (ORNL) are collaborating with roofing industry partners to research and develop cool colored roof products that could expand significantly the use of cool roofing in the residential sector.
When purchasing cool roof elastomeric coatings, building owners can require that products meet the ASTM international standard, ASTM D 6083-05e1, “Standard Specification or Liquid Applied Acrylic Coating Used in Roofing,” to ensure the product achieves certain specifications. There is currently no similar standard for cementitious coatings.
Reduced Energy Use
A cool roof transfers less heat to the building below, so the building stays cooler and more comfortable and uses less energy for cooling. Every building responds differently to he effects of a cool roof. The measured savings varied from 10 to almost 70 percent of each building’s total cooling energy use.
Peak vs Non peak
Proper roofing saves energy when most needed—during peak electrical demand periods that generally occur on hot, summer weekday afternoons, when offices and homes are running cooling systems, lights, and appliances. By reducing cooling system needs, a cool roof can help building owners reduce peak electricity demand.
- The building is in a climate with hot and sunny weather during at least part of the year (80°F or hotter weather with clear skies for at least three months of the year)
- Significant cooling energy is used (three or more months of cooling use)
- The duct system is in the attic or plenum space
- There are problems maintaining indoor comfort in the summer (if air conditioning equipment cannot maintain the desired temperature, or without air conditioning, if indoor temperatures exceed 80°F)
- The roof accounts for much of the building’s envelope (i.e., the roof area equals or exceeds one-fourth of the building’s exterior surface area, calculated as the walls plus the roof)
- The roof materials tend to crack and age prematurely from sun damage (if damage begins before the warranty period or the roof life ends).
Environmental and design expertise for home and commercial building designers.
The better the techniques and products used in building, the longer the home will stand.
Warranted for 50-years with a 120 mph wind warranty, Spartan products are proven to last, and dd to the longevity of any project.
Made from pressed aluminum-zinc alloy coated steel, Spartan premium choices, have the durability and strength of steel.
In addition to the aluminum-zinc alloy coating the panel is covered with ceramic coated granules.
The granules added to the texture increase the aesthetic appeal of the product and provide further protection for building envelope.
