Providing green consulting on a full range of sustainable building topics for projects of all scales to architects, builders, developers, and homeowners.

We educate our clients to create informed choices on the ecological impact and relative cost of decisions made in designing and constructing buildings.  Our goal is to promote eco-sensitivity at the same or lower cost than "standard" building techniques.


Areas of expertise include:

  • natural, healthy & sustainable building materials

  • passive solar design

  • energy efficiency strategies

  • water conservation products & strategies

  • space efficiency

  • waste management (during construction or for building occupants)

  • green cleaning plans

  • indoor air quality

  • natural daylighting

  • LEED analysis (note we do not provide LEED documentation)
