• In2004,theMayor’sGreenBuildingTaskForceissuedrecommendationsthatledtotheadoptionofBoston’sgreenbuildingzoningrequirements.

• In2005,Boston’sEnergyManagementBoardcompletedanIntegratedEnergyManagementPlanfor362municipalbuildings.

Boston also recognizes that

solar power can provide a useful backup

source of electricity for

critical services in the event of a widespread

blackout.
