Green Buildings initially cost more
but are cheaper in operation
Goverment and NGOs take Action
Stakeholder
Investors
 New building codes and regulation
Often do not pay the energy bill and have
little incentive to promote energy efficiency
 Establishment of green building
labels
Architects
 LEED, GreenBuilding, BREAM,
Minergie, Passivhaus etc.
set their focus more on esthetics and tradition
than on sustainability and operational
excellence
General contractors
Are interested in fulfilling the specifications
with the least amount of money
(initial cost focus)
Planning offices
do not have a real incentive to promote
green buildings
Energy savings alone make green building cost effective. Energy
savings alone outweigh the initial cost premium in most green buildings.
The present value of 20 years of energy savings in a typical green office
ranges from $7/sf (certified) to $14/sf (platinum), more than the average
additional cost of $3 to $8 per square feet for building green.
