The document provides information on building green at an Indiana park and recreation conference. It discusses the need to change building habits due to population growth and environmental impacts. Specific strategies covered include using LEED certification, incorporating cost-effective green improvements like native landscaping, water efficiency, energy optimization through measures like geothermal heating/cooling, and using solar power.

26. #2 Incorporate Cost-Effective Green Building Strategies

29. Drive Less Walk, bike, carpool or take public transportation more often. You’ll save one lb of CO2 for every mile you don’t drive. Your car will emit as much CO2 in a year as your entire household = 12,000 lbs.
