A few features make these shingles stand out.
Meeting California Code Compliance
In California, residential roofs must meet solar reflectance requirements because they are mandated by California's Building Energy Efficiency Standards Title 24, Part 6 and Los Angeles County Green Building Code. Both codes set a minimum reflectance rating known as the solar reflective index (SRI), which measures a material's ability to reflect sunlight and heat. Plus la valeur de l’indice de réflectance solaire (IRS) est basse (de 0 à 100), plus un matériau devient chaud lorsqu’il est exposé à la lumière du soleil. Plus la valeur est élevée, plus le matériau reste frais Shingles with a higher SRI help reduce temperatures by reflecting sunlight which can help reduce the cooling load.
The new Timberline HDZ® RS Shingles provide solar reflectance that complies with both Title 24 and the Los Angeles County Green Building Code.
Article 24
California's Title 24 covers the entire state, unless local requirements are stricter, providing cool roof requirements for residential and commercial buildings based on their locations within 16 climate zones. Pour les bâtiments résidentiels (nouvelles constructions), les zones climatiques 1 à 9 et 16 ne présentent pas d’exigences en matière de toits blancs. Climate zones 4, and 8 through 15 require cool roofs for new and reroof applications when more than 50 % of the roof is removed.
If shingles don't meet the required SRI, alternative paths to compliance include using a radiant barrier, airspace, or additional attic insulation.
Los Angeles County Green Building Code
The Los Angeles County Green Building Code's Cool Roof Ordinance covers buildings in the county and prescribes SRI values depending on the type of building (low-rise residential, high-rise residential and hotels/motels, and nonresidential) and roof slope. High-slope (greater than 2:12), low-rise residential roofs must have an SRI of 20 or more. Exceptions apply to roof repairs or replacements where less than 50 % of the roof is removed, additions of less than 500 square feet or less than 50 % of the total roof area, and green roofs.
