  • Just how low the VOC level needs to be for a given product to qualify for inclusion in GreenSpec depends on the product category. For most products, we require certification to California’s health-based emissions standard, CDPH Std Method v1.1 standard (also referred to as California Section 01350), which tests a product’s resultant VOC concentrations in the space after a given period of time. For wet-applied products like paints, caulks, and adhesives, we still also look for VOC content instead of, or in addition to, verified low emissions; this is because emissions testing doesn’t adequately test initial offgassing, and VOC content is currently the only widely available proxy.

  • Included here are various erosion-control products, foundation products that eliminate the need for excavation, and exterior stains that result in lower VOC emissions into the atmosphere. Fluorescent lamp and ballast recyclers and low-mercury fluorescent lamps reduce environmental impacts during maintenance and disposal of luminaires.

Vocomp-20 is low-VOC, water-based acrylic curing and sealing compound with a VOC level of 4 g/l. Vocomp-20 has short application and drying times and was developed as a water-based emulsion to eliminate the use of hydrocarbon solvents.

Concrete curing agents are coatings or admixtures that aid the set and cure of freshly poured concrete. They generally use coalescing agents to retard evaporation. Conventional products use a petroleum hydrocarbon resin base.

GreenSpec lists products made with biobased materials, low-solvent, low-VOC (50 g/l or less), water-based, or some combination of those.
