  1. Brad JohnsonTHESIS PRESENTATION BARRIERS TO CERTIFICATION FOR LEED REGISTERED PROJECTS

  2. INTRODUCTION • What is Green Building • Why is it needed • Resource consumption • Energy consumption • Economics

  3. Green 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

  4. Why 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

  5. Why 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

  6. Why is it needed • Economics • Reduced energy costs • Increased productivity

  7. The United States Green Building Council (USGBC) • Formed in 1993 • The nation’s 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

  8. LEED • 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

  9. THE 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

  10. LIMITATIONS • 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

  11. RESEARCH 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?

  12. METHODOLOGY • The Population • LEED contact persons for projects that were registered before January 1st 2002

  13. METHODOLOGY • 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

  14. Treatment 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.

  15. RESULTS: 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)

  16. RESULTS: Characteristics of Respondents and Projects Type of organization that the respondents worked in

  17. RESULTS: Characteristics of Respondents and Projects

  18. RESULTS: Characteristics of Respondents and Projects

  19. RESULTS: Characteristics of Respondents and Projects • Time in days from completion to certification • Average = 300 days

  20. RESULTS: Characteristics of Respondents and Projects • End use for projects

  21. RESULTS: QUESTION 1- Reasons for certification • Open ended question

  22. RESULTS: QUESTION 1- Reasons for certification • Likert scale question (scale from 0 to 5)

  23. RESULTS: QUESTION 2- Barriers to Certification • Likert scale question (scale from 0 to 4)

  24. RESULTS: QUESTION 2- Barriers to Certification • Open ended question

  25. RESULTS: QUESTION 3- Differences Between Groups • Likert scale question (scale from 0 to 4) CG = Certified Group NCG = Non Certified Group

  26. RESULTS: 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

  27. CONCLUSIONS • 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

  28. CONCLUSIONS continued • Group differences • Ranking of barriers • Cost especially • Reason for certification • Owner driven

  29. FUTURE RESEARCH • Research the LEED documentation process • Cost to benefit study concerning LEED point categories
