The document summarizes a presentation about the cost implications of pursuing LEED (Leadership in Energy and Environmental Design) certification for buildings. It finds that LEED certification can increase initial construction costs by 0-2% but provides financial benefits over 20 years that are over 10 times the initial cost increase, through reduced energy and water use. Certain LEED points are identified as having low or no additional costs, such as optimizing energy performance or using regional materials, while others like renewable energy or green roofs can be more expensive.
