Residential Retrofit Scenario Review

Owner priorities: 1 Comfort · 2 Upfront · 3 Carbon · 4 Operating. Method: gate on comfort, then choose on a cost ↔ carbon frontier. Each dot below is one simulated run — click it to open its full card. Peel the field down by stage to see how the study was built up.

Build-up · the 31 runs by stage

Every run branches from the same calibrated model, then adds one layer. Click a stage to isolate its runs in the field and table; click again (or “All”) to see the whole set.

Comfort gate Max occupied unmet hrs Color by Y axis

· Comfort gate leans on occupied unmet hours (the metric that actually separates these runs). Basement swing and RH are shown as labeled context in each run card — never inferred from an estimate.

All runs — full table (sortable, click a row to open its card)

Grey rows fail the current comfort gate. Carbon / operating shown as delta vs the gas baseline — green beats baseline, red is worse.

Sensitivity lens — re-weightable score (NOT the decision)

A blended score can silently trade comfort away, so it is not the judge. Use it only to ask “does the pick hold if I weight carbon higher than stated?” Applies to comfort-passing runs. Click a bar to open that run.

About this public review

This page compares a fixed set of precomputed scenarios. It is not a design tool, an export, a calculation input, or a way to request a new simulation. Custom combinations require a separate, project-specific engineering review.
