Include details on preparation, protection and any special arrangement required during construction. Reused elements may need protective coverings and sheets from contaminants and construction dust
A good preventive maintenance program will not only identify leaks and obvious problems, but will also include a regular flow and flush rate test for at least 20% of fixtures to ensure continued performance.
When replacing flushometers, make sure that the existing water closet or urinal bowl is capable of providing the flush rate specified on the new hardware. This information should be available on product data sheets or by request from the manufacturer.
If your building supports visitors or retail customers, you will need to calculate the average number of each of these occupant types that use your facilities on a daily basis.
Formal authentication of the fixture upgrade can be met using copies of construction permits, substantial completion notices, contract excerpts, plumbing inspection reports, commissioning reports, or similar documentation.
The assessment must account for potential cost savings on water supply, disposal, and expected maintenance. The economic assessment should, at minimum, determine the simple payback of any new fixture investment. Carefully consider the payback period required to justify your purchasing decision.
Develop a checklist of all interior elements and use this to make preliminary calculations anticipating the percentage of elements that can be reused. Pursue the credit only if these preliminary calculations show that at least 50% of interior elements in the completed building are reused, per the requirement.
