- BARRIERS TO CERTIFICATION FOR LEED REGISTERED
PROJECTS
2INTRODUCTION
- What is Green Building
- Why is it needed
- Resource consumption
- Energy consumption
- Economics
3Green Building/Sustainability
- Optimize Site Potential
- Minimize Energy Consumption
- Protect and Conserve Water
- Use Environmentally Preferable Products
- Enhance Indoor Environmental Quality
- Optimize Operational and Maintenance Practices
- Whole Building Design Guide
4Why is it needed
- Resource Consumption
- Of the raw materials used, an estimated 40 are
used by buildings - In the U.S., in 1996, an estimated 136 million
tons of construction and demolition waste was
generated
5Why is it needed
- Energy Consumption
- Buildings account for 65.2 of total U.S.
electricity consumption - Buildings use greater than 36 of total U.S.
primary energy use
6Why is it needed
- Economics
- Reduced energy costs
- Increased productivity
7The United States Green Building Council (USGBC)
- Formed in 1993
- The nations foremost coalition of leaders from
across the building industry working to promote
buildings that are - environmentally responsible
- profitable
- healthy places to live and work
- Developed the Leadership in Energy and
Environmental Design (LEED) rating system
8LEED
- A definitive standard for what constitutes a
green building (Rocky Mountain Institute, 2002). - A point system where points are given in six
different categories - Differing levels of certification
- Projects are registered and certified through a
process of documenting the points earned in each
category
9THE PROBLEM
- Current building practices
- Green building practices are part of the solution
- LEED, a definitive standard
- Several projects are registered but not certified
- Why are they not becoming certified?
- Little research has been done
10LIMITATIONS
- Projects registered before January 1, 2002
- Only early LEED projects are included
- LEED was new for these projects
- Lessons learned
- Limited to the accuracy of statements and
opinions of respondents - No inference can be made to the population
11RESEARCH QUESTIONS
- What are the motivations for LEED registered
projects to become registered and eventually
certified? - What are some of the encountered barriers for
LEED registered projects to become certified? - What are some of the observed differences between
registered buildings that receive certification
and those that do not?
12METHODOLOGY
- The Population
- LEED contact persons for projects that were
registered before January 1st 2002
13METHODOLOGY
- Procedures
- Identify projects and contact persons
- Develop the survey
- Pilot the survey
- Approval from CSU Human Research Committee
- Send survey to the population
- Analyze the data
14Treatment of Data
- Multiple choice and Likert scale questions were
placed into SPSS - Open ended questions were coded
- Respondents were divided into two groups to
answer research question three.
15RESULTS Characteristics of Respondents and
Projects
- Thirty one respondents were LEED accredited
professionals and 12 were not - Twenty of the 43 projects were LEED certified
- Of the 23 non certified projects 14 indicated
that certification was still a goal - The owner and architect were the organizations
initiating LEED certification (26 and 15
respectively) -
16RESULTS Characteristics of Respondents and
Projects
- Type of organization that the respondents worked
in
17RESULTS Characteristics of Respondents and
Projects
18RESULTS Characteristics of Respondents and
Projects
19RESULTS Characteristics of Respondents and
Projects
- Time in days from completion to certification
- Average 300 days
20RESULTS Characteristics of Respondents and
Projects
21RESULTS QUESTION 1- Reasons for certification
22RESULTS QUESTION 1- Reasons for certification
- Likert scale question (scale from 0 to 5)
23RESULTS QUESTION 2- Barriers to Certification
- Likert scale question (scale from 0 to 4)
24RESULTS QUESTION 2- Barriers to Certification
25RESULTS QUESTION 3- Differences Between Groups
- Likert scale question (scale from 0 to 4)
CG Certified Group NCG Non Certified Group
26RESULTS QUESTION 3- Differences Between Groups
- Forty five percent of the certified group stated
as a reason for certification owner driven none
of the non certified group stated this as a
reason. - The non certified group mentioned cost more often
as a barrier than the certified group - The certified group mentioned a lack of
awareness, education or experience as a barrier
more often then the non certified group
27CONCLUSIONS
- Reasons for Certification
- Environmental stewardship
- To keep green building a project priority
- Owner required
- Barriers to certification
- LEED documentation
- Lack of education
- Cost
- Communication
- Lack of team buy in
28CONCLUSIONS continued
- Group differences
- Ranking of barriers
- Cost especially
- Reason for certification
- Owner driven
29FUTURE RESEARCH
- Research the LEED documentation process
- Cost to benefit study concerning LEED point
categories
