Residential and hospitality projects that use low-flow showers, lavatories, and kitchen sinks (contributing to WEc3) benefit from lower energy use due to reduced overall demand for hot water. However, for energy-savings calculations, these are considered process loads that must be modeled as identical in baseline and design cases, or you have the choice of demonstrating the savings with ECM for process loads.
