Four steps from IDF to optimal design
Define variables
Set design parameters, such as WWR, shading depth, glazing type, orientation, with ranges and constraints.
EnergyPlus sampling
Latin Hypercube Sampling generates diverse design combinations; each is simulated automatically.
Surrogate training
XGBoost learns from the simulation data and evaluates thousands of candidates in seconds.
Pareto front export
NSGA-III finds the optimal trade-off surface. Archive, CSV, and PDF report exported automatically.

Everything you need, in one pipeline
Multi-objective NSGA-III
Optimize energy, embodied carbon, and comfort simultaneously, handles 4+ objectives without losing solution diversity.
Full IDF parametric control
Tag-based IDF substitution gives direct control over any EnergyPlus parameter, geometry, materials, HVAC.
XGBoost surrogate model
Orders of magnitude faster than brute-force simulation, and generalizes accurately from the sampled data.
60-year lifecycle analysis
Scale energy and carbon results over the full building lifetime, with a user-configurable study period.
Embodied carbon calculator
Built-in material database with quantity take-off, tracked alongside operational energy in every run.
Global sensitivity analysis
See which variables drive performance most, the levers worth pulling before you commit to a design.
