  • Simulating large buildings: Large buildings (e.g. over 1M sq ft), and high-rise buildings (e.g. greater than 30 floors) may either take several hours to simulate, or result in an "out of memory" error. Options for developing a solution are currently being explored.
  • AS currently expects assembly components to be assigned to all roofs and floors, including interior surfaces. Options for preventing assigning components to adjacent roofs and floors are currently being explored.
  • The following HVAC systems are presently unsupported in Asset Score:
    • Multiple Zone Water Loop Heat Pump with Reheat
    • Multiple Zone CAV with Reheat
