This project is a prison complex, comprised of multiple buildings with multiple uses. As such, a wide variety of plumbing fixtures are required to be installed, many of which are not expressly addressed within the Energy Policy Act of 1992. This inquiry relates to how certain unconventional fixtures should be addressed within the context of the WEc3 Letter Template Calculator. Fixture types installed at this facility that we believe fall within the purview of EPAct 1992, and should be included in our calculations, include: combination units in the cells, lavatory sinks, water closets, urinals, hand wash fountains, hand wash sinks, janitor sinks, kitchen sinks, and showers. We have included all such fixtures in our WEc3 calculations. Based on several rulings within WEc3.1 and WEc3.2 which specifically state that optimization of process water use is not eligible to receive credit under WEc2 and WEc3 and that process water includes, but is not limited to, water use from cooling towers, dishwashers and clothes washers, fixture types installed at this facility that we believe can be excluded from our calculations are: institutional clothes washers, institutional dishwashers, eyewash fountains, emergency showers, barber sinks, clinical sinks, bar sinks, plaster sinks, scrub sinks, maintenance sinks, permanent water coolers, and permanent water fountains. We would like confirmation that our understanding of the included and excluded fixtures is correct.
