LEED Cost
How much does a LEED building cost more
than your traditional building?
What standards are associated with your
traditional building?
How much more does LEED cost above code?
How Green is/was your last project?
What level of certification are you striving for?
How experienced is your local contractor /
design community?
Current Soft Cost Data
Estimated soft
costs
(www.facilitiesnet.com)
People costs v.
Energy or
Construction
costs
Current Cost Data
Building costs represent
less than 10% of the cost
to own/operate building
for life of project – 20
year lifecycle.
(www.facilitiesnet.com)
Cost Literature Review
LEED costs
GSA sites a range of less than 0% for LEED certified to
a mean of 2.5% addition to total budget for LEED
silver buildings.
UF Facilities Planning and Construction claim $0
additional dollars for a LEED certified building.
Davis Langdon (architect firm) states design firms
produce LEED buildings as standard program elements
(no additional design fee).
Greg Kats – Average Silver rating for schools (n=33)
cost premium = 1.84%
Common perception minimum of 10%
Conclusion on First Costs
AsUF has gained experience with LEED
projects the associated first costs and process
has evolved. Major drivers of lowering costs
include:
Experience of project team members and local
market
Evolution of building standards to include LEED
based language
Outcome based selection of credits and levels of
certification
