Economic Finance Issues
29
Green Building Costs are Reasonable

• Lifecycle costs far below conventional buildings
• Silver for free
• Better design reduces change orders
• Advanced energy efficiency for pennies/square
  foot
• BUT, must pay tuition

30
First Cost

• How much does it cost to build green?
• Compared to what?
• Quality
• Location
• Climate
• Code
• Local Practise
• Local materials resources
• Planning requirements
• Utilities
• Environmental value engineering

31

34
Life Cycle Cost

• Financial benefits from
• Longer building life
• Improved productivity
• Occupant health comfort
• Design and operation to optimize life cycle cost
  is better for the environment

LEED What it is...

• Provides a definition for green buildings
• US market-based standard to distinguish and
  promote sustainability
• Tool to introduce, promote and guide
  comprehensive integrated building design

37
LEED What it is

• Self evaluating and documenting
• Rigorous, transparent, easy to use
• But not easy to achieve
• A living document
• Ongoing consensus process involving many
  stakeholders

38
LEED What it is Not...

• Self certifying
• Done by USGBC
• The ultimate definition of green design
• Moving toward sustainability
• A tool to prioritize environmental impacts of
  buildings
• Must come from the Owner
• A guarantee of good building design
• Thats up to the Design Team
