1. A computer based method for evaluating energy efficiency of building massing configurations in a building design process implemented by a building realization platform, the method comprising:

  • specifying a set of parameters for a building massing configuration;

    calculating a normalized energy use index indicating energy efficiency for multiple different building massing configurations that meet the specified set of parameters, wherein the normalized energy use index for each of the multiple different building massing configurations is normalized against a reference energy use index of a reference building;

    ranking the multiple different building massing configurations by the respective normalized energy use indexes;

    selecting at least one of the different massing configurations for display on a graphical user interface according to the ranking; and

    outputting the ranked multiple different building massing configurations to the building realization platform, wherein the corresponding normalized energy use indexes for the ranked multiple different building massing configurations are used to realize a building design;

    wherein the normalized energy use indexes for multiple different building massing configurations that meet the specified set of parameters are calculated from pre-derived shape-specific normalized energy use index formulas;

    wherein at least one of the shape-specific normalized energy use index formulas is a function of Rs, wherein Rs=Be/Bfp, where Bfp is the number of bays in the footprint of a particular building massing configuration, Be is the number of bays along the exposed perimeter of the particular building massing configuration, and each bay is the same size.
