Defining Sustainability : Meeting the needs of the present
without compromising the needs of the future.
How does this relate to the construction industry?
 We, in the construction industry by the nature of our business utilize a
tremendous amount of resources and energy in order to build
structures.
 Our challenge is to build structures that work with the environment,
minimize energy and resource use and actively pursue building spaces
with healthy indoor environments.



This is what most people think
of when they hear the term
‘green building’
There is a perception that
green is brown and doesn’t
incorporate beautiful design
And somehow these same
people think THIS costs 20%
more
Perception



But this is the reality of
green design in the
marketplace
Proving green interiors do
not have to sacrifice on
amenities
This is the REI Portland store
proving green design can be
functional, urban and
modern
Reality

There is no simple answer to this question as it depends on
the job. Some jobs can reach a Certified level at very little or
no cost above conventional construction practices. Jobs
seeking Gold or Platinum levels of Certification typically
require expenditures to achieve these levels. It is important
to understand that these expenditures are adding quality
and should be looked upon as quality enhancements to the
project.


Owners that are pursuing these ratings are doing so because
they are getting a higher quality project that is expected to
more than pay for the increases in 1st costs over the life of
the facility. (This is one of the barriers that tend to thwart
Spec office builders from pursuing Green Buildings.)
These 1st costs are offset by the following:
 Decrease in energy costs due to increased energy efficiencies of the
building.
 Decreased Maintenance and operating costs due to better HVAC
Systems and Exterior Envelope Systems.
 Increases in employee productivity.
 Less absenteeism, sickness, insurance claims



Buildings are LEED Certified
People are LEED Accredited
Materials are neither
 LEED is an overall design concept, not depending on individual
materials
