Climate Adaptation Public Space
DKK 48.45M investment — what a 2019 analyst would have predicted, and what seven years of validated data confirmed.
A Phase 1 Desk Assessment — conducted remotely from drawings, site plans, and publicly available data. All projections were made at design stage. The 2026 figures are post-occupancy validated outcomes.
Indicators were selected based on the purpose of the design (climate adaptation, public space), public data availability for Copenhagen, and measurability within a Phase 1 framework.
Type 1 (Calculated) — quantified, sourced, defensible monetary value assigned.
Type 2 (Evidenced) — documented effect, no monetary figure assigned at Phase 1.
The project was designed to achieve 30% surface infiltration across its catchment. Post-completion monitoring confirmed 50% — almost double the specification.
The economic value is calculated against HOFOR's published 2026 tariff schedule. The 60% outperformance is driven entirely by technical delivery exceeding design specification — not by tariff growth.
The biological projection was accurate to within 3.4% — the trees sequestered almost exactly what the IPCC age-bracket methodology predicted. The 107% value increase came entirely from EU ETS carbon prices rising from ~€42 to €90/tonne.
The 586 trees are an appreciating asset. Between 2026 and 2030, annual carbon value is projected to increase by 159%.
The 2019 market baseline grew far faster than forecast — a post-COVID surge no model predicted. But the green premium estimate proved accurate: 5% projected, 4.5% validated. The methodology measured the right thing correctly.
For municipalities: DKK 14.5M annual tax increment = fiscal payback in approximately 3.2 years. For private developers: DKK 428M neighbourhood asset creation = 8.8× project investment.
The 2019 temperature prediction was accurate to within 0.1°C. The methodology applied IPCC-derived tree cooling coefficients to the design specification — 586 trees across 48 species replacing 9,000 m² of asphalt.
The health cost is calculated using a published EPFL/Nature Communications coefficient (Manoli et al., 2023) of €192 per adult per year, applied proportionally to the 17.2% cooling contribution of the project.
Cross-referencing SLA's 2026 monitoring report (34.9°C → 28.9°C = 6.0°C = 17.2%) confirms the mid-scenario prediction was met precisely.
A monetary value is not assigned to this indicator. Doing so without clinical outcome data — measured changes in depression rates, GP consultations, or anxiety scores in the catchment — would be an inflation, not an assessment. The effect is real, evidenced, and documented.
Design projection vs. validated outcome, 2026. Every indicator met or exceeded its 2019 forecast.
