WATER: Are there any retrofits I can use to regulate the flow of the current toilets instead of installing new ones?
No. Although flush valves (the mechanism you press down to flush the toilet) can be changed to reduce flush volumes, flush volumes after these retrofits are still higher than the 1.6 gpf standard required by the program, therefore, a flush valve retrofit will not help you qualify. All Green Businesses must use low flow toilets (1.6 gpf) or high efficiency toilets (1.3 gpf).
