On August 5,2009, the Tucson Mayor and Council approved a voluntary Green Building Program for residential (one to three units) structures. The Green Building Program is the result of significant work that has taken place with other jurisdictions,  SAHBA, non-profit and for-profit builders, and builders who specialize in green building techniques.  Suggested practices include orientation of the building and windows, energy efficient building techniques and appliances, and the use of photovoltaic and solar devices to create energy.
