Natural Resources Canada (NRCan) software

  This quick and easy tool analyzes energy use in homes with only a small amount of critical information. The graphical interface is simple enough to be used by homeowners or by home energy evaluators as a fast gateway to research-quality analysis. For much of the simple single-family housing stock, HOT2®XP can give results as accurate as those of HOT2000 or similar programs. However, as the complexity of a house increases, the HOT2®XP simulation may become more approximate. To maintain a high level of accuracy, the user may be required to override an increasing number of program defaults, or may prefer to switch to HOT2000.

HOT2-EC is a special version of HOT2000 that provides compliance with MNECH 1997. A house file created in HOT2-EC can be loaded into the latest version of HOT2000 but the reverse is not true. This saves users from inputting their design twice in order to use each program. Note that HOT2-EC does not contain all of the features and capabilities of HOT2000 and will be updated when the MNECH is updated.
