Hundred-Year View
Scrub a design from 2026 to 2126 and watch what a century actually costs it: the site's warming offset in Δ°F, and a carbon curve that climbs with every year of operations, bends as the grid decarbonizes, and steps each time the glazing or the roof is replaced — with the crossover year where the century overtakes the up-front spike. The assumptions driving all of it (conditioned hours, grid target, service lives) are yours to set and argue with. Each lane says out loud when its data runs out (solid = modeled, dashed = extrapolated). Reads the Work's saved Architect design, or runs the studio's default pavilion as a worked example. No AI calls.

Running Eco-Architect's default pavilion (a worked example, not your Work). Save a design to a Work from Eco-Architect V4 and it replaces this one — the assumptions below stay yours either way.
Climate — warming offset
no data — see below
- Climate deltas not loaded yet — they come from the Open-Meteo Climate API for the design's site; if the fetch fails the lane stays dark rather than inventing a curve.
Carbon — embodied + operational
31,446 kgCO₂e in 2026 modeled
dashed throughout — only 2026 is modeled, so every later year on this curve is your assumptions running forward
- Embodied (year 0)
- 30,700 kg
- Replacements to 2026
- 0 kg
- Operations to 2026
- 747 kg
- Crossover year
- 2106
- The stored design carries geometry only — no comfort run, so the conditioned hours below are YOUR assumption, not a measured figure. Load a climate in Eco-Architect V4 and run comfort to replace it with the design's own hours.
The century's assumptions
Every number below is an assumption, not a measurement — yours to set and to argue with. They are what turns a building into a hundred-year story, so the curves above move when you move them.
Hours a year the building runs heating or cooling. A comfort run in Eco-Architect V4 measures this; until then it is a guess. Zero = never conditioned.
Average electrical draw during those hours — a small heat pump duty-cycling, not a measured load. The operational slope scales straight off this.
Where the US grid ends up, as a share of the cited eGRID2022 figure (0.373 kgCO₂/kWh), reached on a straight line. 100% freezes today's grid for a century — try it and watch what that assumption alone was worth.
After this year the grid holds flat. At 2026 the curve is using 0.373 kgCO₂/kWh.
How long before the glazing is torn out and re-bought at its full embodied cost (module B4). 0 = never replaced — the assumption this tool used to make silently.
Same for the roof build-up. A thin sheet roof is a wearing surface; over a century the difference between 40 and 50 years is a whole extra replacement.
