Green Buildings and Solar Systems Overview

• Why Green Buildings?• Federal Programs• State Programs• City Green Building Initiatives• Steps residents can take to reduce energy

used in their home• Photovoltaic system permit process

4

Why Green?

• The level of Carbon Dioxide in the atmosphere is increasing and causing global warming

• Global warming is causing environmental effects including an increase in sea level

• Too rapid an increase in sea level can cause tremendous damage to infrastructure in coastal areas

We can make a difference

• Reduction in CO2 production can delay sea level rise and give us more time to respond and relocate as needed

• Use of renewable and sustainable resources protects the environment
