FAQ
Questions Energy Efficiency Estimator owners ask.
- 01
What inputs are needed to get the initial score?
The core metrics include total heated area, wall thickness, and combined U-values. The query_structure_thermal_score capability uses these inputs to generate the raw thermal index.
- 02
Does my home's direction matter for the score?
Yes. The query_orientation_bias capability accounts for passive solar gain and wind loads (e.g., South-East vs. North). This factor modifies the score to give a regionally accurate assessment.
- 03
How do I know what to fix after the rating?
After receiving your A-E classification, use the query_improvement_recommendations capability. It analyzes component weaknesses and provides a prioritized list of actionable upgrades (e.g., upgrading glazing or improving roof insulation).
