For residential projects, showers typically use more water than any other fixtures due to the duration of use. For commercial projects, toilets and urinals typically use more water. Water-saving strategies should target the most consumptive fixtures to achieve greatest water reductions.
The architect or acoustics consultant calculates total ceiling area and decides whether Option 1 (all ceiling material to have an NRC of 0.70) or Option 2 (a combination of ceiling, wall and floor material has a combined NRC of 0.70 for an area the same size as the ceiling area) is best for the project. Option 1 is the most straightforward but might not be possible for all projects due to design constraints such as, ceiling material selection, classroom layout and programmatic issues. Research other design strategies and compliant products.
Select water-efficient fixtures and strategies. Gather information on applicable fixtures including manufacturer, model number, and flush or flow rates.
Reverberation Time: Case 1, Classrooms and Core Learning Spaces less than 20,000 ft3
Acoustic requirements can add minimal upfront costs associated with upgraded mechanical equipment, wall assembly design, and materials selection.
Including microphone and speakers in a classroom design or other electronic amplifiers will not contribute to credit compliance. Amplification allows the teacher to be heard more easily but does not reduce reverberation time or background noise levels.
Commercial Interiors projects registered after July 19, 2010, if they do not install or modify any fixtures in the base building restrooms, should copmlete calculations for WEp1 that only include fixtures within the tenant space/LEED-CI Project Boundary (the kitchen sink). However, the calculations for WEc1 must include all fixtures that are used by the LEED-CI project occupants (both within and outside of the LEED-CI project space).
Well water and pond water are not considered “reused” water for the purposes of this credit and must count as potable water—so you don’t get credit for substituting them for conventional water sources. Water types that do count as reused are: graywater (lavatory, sink and shower water), rainwater, treated wastewater, air-conditioner condensate, reverse-osmosis reject, and sump-pump water.
Painting sound-absorptive materials could affect the acoustic performance of the material; check with manufacturers before specifying any paints.
