There is a currently an ENERGY STAR tool called Target Finder. During a building’s design phase, Target finder provides either an energy performance score based on a building’s design energy or a design energy based on a building’s energy performance score target. The functionality of Target Finger is also included in the new web services as “Design” web services. For info on the current Target Finder, see: http://www.energystar.gov/index.cfm?c=new_bldg_design.bus_target_finder
There are separate web services to submit and retrieve design data and metrics for a property -- please see the Design section of the property API documentation at http://portfoliomanager.energystar.gov/webservices/home/api/property.
