This report was conducted by the Applied Economics Office in the Engineering Laboratory (EL) at the National Institute of Standards and Technology (NIST). The report is designed to document the assumptions used in creating the whole building energy simulations used for new commercial building prototypes. The intended audience is the building research community, particularly those concerned with energy efficiency in commercial building designs.

This report documents the prototype building designs and the lifecycle costing and carbon assessment data and approaches implemented in the BIRDS building energy efficiency and sustainability database.
