Create your Sustainability Management Plan Clarify the following: • Who is responsible for what? • What trades are affected? • What are the documentation requirements and how will they be met? • What work practices are required and how will they be verified? G|PRO The Sustainability Management Plan (SMP) Pages 12 -14

CLASSROOM EXERCISE: Sustainability Management Plan The CM generates the SMP to coordinate the execution of the sustainability measures. G|PRO Classroom Exercise #3 Page 63

CLASSROOM EXERCISE: Now make the argument to the Owner about how you plan to achieve each credit. G|PRO Classroom Exercise #3 Page 63

Sometimes Points are Eliminated Delete Solar Thermal System: Financial criteria: Proposed solar system will have a long payback period (increasing water efficiency means less hot water being used) Site logistics: Turns out that the solar thermal system doesn't have adequate southern exposure G|PRO
