Building Green

D1 operates under a robust Lean manufacturing environment where the elimination of waste is an essential core value, practice and result.

VOC Gas Elimination: In 2001 D1 switched to 100% low-VOC glue, and in 2003, all spa plumbing was converted from glued joints to barb and clamp, further reducing VOCs (Volatile organic compounds). D1 also drastically reduced VOC emissions by switching from fiberglass-reinforced polyester (FRP) products to urethanes, which emit no VOCs.

Sustained Forest Lumber Exclusively: All D1 framed wood construction uses lumber from Sierra Nevada-grown sustained forests, thus protecting our nation's venerable old-growth forests.

Forest Stewardship Council Support: D1 uses FSC paper in most of its print-based materials. Paper products with a "mixed sources" label support the development of responsible forest management worldwide. Such paper is from FSC-certified and well-managed forests and/or post-consumer reclaimed material.

RoHS Directive Support: RoHS is the European Union's stringent regulation that restricts the use of hazardous substances in electronics. The directive, more commonly known as the Restriction of Hazardous Substances Directive, bans the placement of electronics on the EU market that contain specified levels of lead, cadmium, mercury, chromium and other substances. D1 sells widely in Europe so the electronics used in our products are RoHS compliant.
