To get a score for a design project in Portfolio Manager (or Target Finder) you are required to enter estimated annual whole-building energy use. This energy use includes the energy for heating, cooling, lighting, pumps, fans, domestic hot water (DHW), plug loads, and elevators. Any calculation process that yields these contributions is acceptable. Users often conduct building energy simulations using programs such as Trace, HAP, DOE-2, and eQuest to determine the building’s energy use, and then add calculated energy requirements of other systems, such as DHW, to obtain the final values.
If your design project earns 75 or better, you may be eligible for Designed to Earn the ENERGY STAR certification. More about the Design to Earn the ENERGY STAR certification process.
