The Asset Score Tool (AST) is a quick and easy way to determine the overall energy efficiency of your building's physical characteristics and corresponding energy consumption independent of occupant behavior.
The energy use in commercial buildings is not constant. It changes with the seasons, from year to year, as tenants come and go, and with changes to building components. Building science researchers know that the energy performance of commercial buildings declines over time – different parts of the system start to age and building occupants invariably alter the “optimal” settings.
The US needs to develop a coordinated program to architect and build the next generation power grid or Smart Grid, harness renewable energy sources and reduce its carbon foot-print while expanding generation and distribution capacities (see  for additional details).
Building 101 in the Navy Yard is the temporary headquarters of the U.S. Department of Energy’s Energy Efficient Building Hub. The building, owned by the Philadelphia Industrial Development Corporation (PIDC), has become one of the nation’s most highly instrumented commercial buildings.
