v0.8.1
44940b49 · ·0.8.1 — a saved scenario can be loaded back in Restores every lever from a current-version file and reproduces its emissions exactly. Reports retired, absent and clamped settings, and flags model drift when a file predates a change to the calculation.

v0.5.0
1f679889 · ·0.5.0 — the building stock replaces the calibrated metamodel Mapping the peak aggregation found three defects rather than a formula: it divided by the peak efficiency twice, anchored 40 GW against the 2020 useful heat rather than the 2020 peak load, and read the wrong efficiency row for district heating. Corrected, the reference transition multiplies the electric-heating peak by 1.27 instead of holding it flat: 39.45 -> 51.0 GW.

v0.5.1
cbf34c17 · ·0.5.1 — wood is priced, heat networks become a choice, net zero gets a verdict Wood carries 27 gCO2/kWh in 2050 as it does in 2020, worth 2.06 MtCO2. The district-heating mix becomes four levers, and its heat pump is the only thermosensitive one. The dashboard says whether the scenario reaches net zero.

v0.6.0
eaab04c7 · ·0.6.0 — a material account for the transition 6 568 kt of steel a year, 34% of the steel the scenario's own industry produces. One-way by design: nothing reads it back. All of it from a local workbook after the web research was blocked.

v0.8.0
7159701b · ·0.8.0 — the building usages, and an electricity mix that follows the demand 271 TWh of hot water, cooking, cooling and specific electricity, previously outside the account. The supply is one of RTE's six 2050 scenarios, scaled to the demand the model computes, and its build rate drives the material account.

v0.4.0
243d2de6 · ·The Net Zero Game 0.4.0 Waste-heat recovery and cross-cutting energy efficiency, both coupled to the combustion that produces them: fuel that is never burned rejects no heat, so efficiency and electrification shrink the waste-heat gisement they would otherwise have recovered. Efficiency is bounded by the potential RTE identified, branch by branch, so the lever says how much of it is captured rather than how much exists. Reference scenario unchanged: 49.34 MtCO2 on the model's perimeter, 621 TWh of electricity, 77.47 MtCO2e national gross against the SNBC 3 objective of 63.

v0.3.0
c4044130 · ·The Net Zero Game 0.3.0 The reference scenario no longer contains a residual where a calculation belongs. The rest of industry is modelled, with output and processes on separate levers so growth cannot pass for decarbonisation. 49.34 MtCO2 on the model's perimeter, 621 TWh of electricity, national gross 77.47 MtCO2e against the SNBC 3 objective of 63.
