Green Materials and Resources
The environmental impacts of building materials occur in their extraction, manufacturing, processing and transportation. Utilizing materials that are salvaged, contain high recycled content, are extracted and manufactured regionally, are made from renewable resources, or are certified by organizations such as the Forest Stewardship Council are practices that help reduce or even eliminate these impacts.
Reusing and repurposing components, architectural elements, and even whole buildings avoids the impacts of manufacturing new materials while helping San Francisco retain and celebrate its history. Construction and demolition waste make up about 22% of all solid waste in California. For example, the construction of a new 2,000-sq. ft. custom home produces an average of 7,000 pounds of waste. Most waste (in many cases all) can be avoided through careful planning, construction management, and strategic specification of materials.
San Francisco is habitat for 800,000 people – meeting needs for space to work, play, and learn; for food, water, and air; for community with local flora and fauna. SF Environment provides support for urban agriculture and forestry and green buildings, helping residents and businesses harness environmental opportunities.
