As soon as you decide to build green, begin letting the media in your area know about your project. Making phone calls, rather than issuing press releases, is a more effective way to establish contacts with local reporters.
For wider notification about your achievement, you may also want to print and distribute a concise, engaging description of your project's most widely appealing and innovative features (including your LEED certification goal, if you have one). Include photos, if available, and a contact number for setting up a tour once the project is complete.
