Advanced framing, or Optimal Value Engineering (OVE), is a
systems approach to the design, engineering, and construction of
wood-framed structures that reduces lumber use, minimizes wood
waste, and maximizes a structure's thermal efficiency. View this
fact sheet for details on how to implement various strategies.
Fly Ash Concrete (Build It Green fact sheet, .pdf) Fly ash is a
waste product that can be substituted for large portions of
Portland cement, significantly improving concrete's
environmental characteristics. Fly ash, consisting mostly of
silica, alumina, and iron, forms a compound similar to Portland
cement when mixed with lime and water. Fly ash is a noncombusted
by-product of coal-fired power plants and generally ends up in a
landfill. However, when high volumes are used in concrete
(displacing more than 25% of the cement), it creates a stronger,
more durable product and reduces concrete's environmental impact
considerably. FSC Certified Wood (Build It Green fact sheet,
