As long as 80% of the installed domestic hot water heating capacity is metered, you can include the meter. Having a meter on your boiler (that heats 100% of the water demand) meets the requirement for Option 2 of the credit. As long as Option 1 is fulfilled (whole building water meter) and your cooling tower meter meets the Option 2 requirements, the domestic hot water meter will satisfy Exemplary Performance.

We are thinking to install meter for hot water. However we can only put meter for kitchens of two restraunts. There are other places where people use hot water, like small pantry for offices and toilets. We are thinking to calculate the amount they use in kitchen and compare it to the other usage to demonstrate kitchen usage is more than 80 % of all hot water. Do you think it works all right for the point? Thank you.

Shoko, Good question. Yes, I think as long as you can show that the kitchen and 2 restaurants account for at least 80% of the hot water, you are within compliance. Sorry for the delayed response. Natalie
