Sage Homebuilders, LLC (http://www.sageSTL.com) is a green-only custom and spec home builder that's built on a building philosophy that marries the high performance of green building (industry best-practices, hyper energy efficiency, improved air quality and comfort, and environmentally conscious design and construction) with the aesthetic appeal of high design.
Sage is versed in the HBA / GBI Green Building Guidelines, USGBC LEED-H (for homes), and is an Energy Star partner. All Sage homes are built under a minimum HBA Green Building guideline Bronze standard, and all are 3rd party verified. Whether you choose Sage or another builder, if you decide to build or buy "green" be sure that it's 3rd party verified!
Sage's "Owens Corning Near Zero Energy Home" will be featured among the homes included in March '07's NAHB Green Building Conference here in St. Louis. After the conference, tours and lessons about the green construction of the home can be arranged by calling 314-495-0718.
