As part of the energy design synthesis method, complex dynamic building simulation
database was created with IDA ICE code for all family house building configurations
for a considered problem. In this paper, the annual heat energy demand output parameter
is considered to serve as basis of a building energy design investigation. The sensitivity
analysis performed by Morris' elementary effect method was used. As the result of
the sensitivity analysis of the output parameter, the most important input parameters
can be identified, that influence the buildings' energy efficiency, that can support
further building designs.
