We are building an addition to an existing building that has a central plant that is outside of our LEED boundary. However, we also have a contract to improve the performance of the central plant. We are purchasing steam from Con Edison. Under LEED, we are allowed to either Option 1 Path 1, where by we assign costs to all purchased energy, or Option 1 Path 2, whereby we account for the central plant. Is it possible to use Path 2 to account for the central cooling plant, which is owned by the project owners, without accounting for the central heating plant, which is owned by ConEdison? In this scenario, we would still use the purchased rate of steam to price our heating energy.
