Gunnar Hubbard- LEED vs Three Star Green Building Rating SystemsGeoffrey Lewis
The best English language presentation on the differences between the US Green Building Council's LEED system and the Chinese government's Ministry of Construction Three Star green building rating system. Also a great overview on how rating systems drive market transformation.
Presented by Gunnar Hubbard, CEO of Fore Solutions, on March 25th, 2009 at a green building event at the Canadian Embassy in Beijing.
Buildings use approximately 40% of the energy in the US. Buzzwords like “going green” and “energy efficient” are more prevalent today. LEED is a rating system, which provides designers the opportunity to tailor their design to reduce the impact on society and the surroundings. It is an integrated process involving the architect, landscape architect, civil engineer, MEP (mechanical, electrical and plumbing) consultant, lighting designer and contractor. As a design team these professionals evaluate energy trade offs within a conceptual design to create a functional building. This session will focus on LEED V4. It will target LEED’s definition, history and categories. More importantly, how to become a LEED accredited professional and LEED’s V4 holistic approach to building design.
John Cusick, Assistant Specialist at the UHM Environmental Center, discusses the current unsustainability of Hawaii tourism, and presents examples from Hawaii and abroad of how that might be changed. Slides from the REIS seminar series at the University of Hawaii at Manoa on 2009-10-29.
Dora Nakafuji from HECO describes plans to meet the renewable electricity generation goals set forth by the Renewable Portfolio Standard (RPS) and Hawaii Clean Energy Initiative (HCEI). Slides from the REIS seminar series at the University of Hawaii at Manoa on 2009-11-12.

41. CONCLUSIONS
OVERVIEW WHAT IS LEED? LEED EB O&M CASE STUDY ENERGY EFFICIENCY + CONSERVATION
• LEED is the future of the building industry.
“It may be called green building now,
but it’s just the right way to build”
• Energy Conservation and Energy Efficiency
- are keys for sustainability
- can reduce global warming and air pollution
- offers the quickest implementation and best
payback.
• Renewable energy should be considered only after
implementing all energy conservation measures in
buildings.
