Dear all,

We are developing the design phase of a LEED Project which is already registered in the LEED online. This project is an adittion to an existing building (same owner) and in the LEED Boundary registered is only including the new construction. The designers of the Domestic Hot Water system are planning to use an existing boiler located within the Existing Building because the hot water systems of this Building is able to provide it to the new construction. Considering this issue, is it necessary to modify the LEED Boundary including the part of the existing building which the boiler is located? And considering this issue, is it possible to modify the LEED Boundary into the LEED Registration data of this project?
