Chemical Concentrates and Portion-Controlled Dilution

Good question. LEED isn't requiring that projects purchase chemical dilution control equipment in order to get certified, but they are promoting it as a best practice that should be given serious consideration for a long-term high performance cleaning plan. Proper use of concentrates reduces over-use of cleaning chemicals, saves money, reduces waste from packaging and minimizes the risk of improper storage and spills. If your project doesn't have one of these systems, your plan should either indicate a timeline for adopting the dilution system or thoroughly describe how your chemical management procedures still meet the intent of the credit.
