Drop a residential HPXML file below. Your browser will import it, fetch the weather year for its station, and simulate all 8,760 hours with the same engine our design tool runs. The home never leaves your machine — only the weather file is downloaded.

This demonstration runs an ideal-loads annual load simulation with standard occupancy-derived internal gains; it models the envelope and weather, not a specific piece of equipment. Results are estimates, not certified ratings, and this page is not a compliance tool. The sample home is a slab-on-grade sample file from the open-source OpenStudio-HPXML project, redistributed under its BSD-3-Clause license. Weather data is served from Aris’s station library; US stations are supported.
