With the introduction of the Water Use Reduction Prerequisite in LEED 2009 rating systems, every project team is required to complete these calculations to demonstrate a minimum percentage of water use reduction. Many teams think they have this credit figured out, but many errors are made when project teams complete these calculations. This consequently results in the prerequisite and/or credit being pended or denied during the certification review process.
This addresses issues such as proper calculation methodology, accounting for urinals in buildings, proper weighted calculations for dual-flush toilets, public vs. private fixtures, fixture usage groups and the use of proper gender ratios, and how to successfully submit the LEED v2009 Prerequisite/Credit Forms in LEED Online.
This course is for anyone working on a LEED project and will address issues such as proper calculation methodology, accounting for urinals in buildings, baseline flow rates required for fixtures, proper weighted calculations for dual-flush toilets, public vs. private fixtures, fixture usage groups and the use of proper gender ratios, and how to successfully submit the LEED Prerequisite/Credit Forms in LEED Online. Learn what reviewers are looking for and how to submit it right the first time.
Course takers should familiarize themselves with the credit language in LEED 2009 WEp1 and WEc3 LEED for New Construction and Major Renovations before taking this course.
