Work with the original design and construction team if possible to identify opportunities for optimizing building systems and operations during the recertification process.
If the building has not received previous LEED BD&C certification consider pursuing one of those LEED certifications if any major renovations are planned. Once that process is completed, you can pursue LEED-EBOM certification.
While most LEED-CS buildings have tenant guidelines in place that address green building practices, it is less likely that at least 75% of tenant spaces will actually be certified under LEED-CI.
Determine if the project building received previous certification under LEED for New Construction and Major Renovations (LEED-NC), LEED for Schools, LEED for Retail–NC, LEED for Healthcare, or LEED for Core and Shell (LEED-CS). If it did, assemble copies of the official USGBC LEED scorecard for credit documentation.
In buildings with older or diverse fixtures, it may be difficult to find product documentation of flow and flush rates. Identify fixtures by brand and model information, and contact manufacturers for assistance.
Provide manufacturer data verifying the flush/flow rate of all installed fixtures and fittings that either exceed or do not meet UPC/IPC specifications.
Replacement of traditional fixtures with high-performance alternatives may require higher upfront costs. However, these fixtures will conserve water as well as energy (from hot water), and will generally offer a favorable payback.
If you have a pre-1993 building, and are planning on performing a major bathroom renovation as part of the overall LEED project, be sure to register the project with the USGBC before starting any retrofitting, in order to claim the less stringent 160% baseline case.
