Future climate boundary conditions dataset for building performance simulation in Morocco: 2,304 CMIP6-morphed EPW files (2030–2090)

This dataset provides 2,304 morphed future EPW (EnergyPlus Weather) files for 16 cities across all six RTCM climate zones of Morocco, generated via GCM-self-referenced delta morphing (shift and corrected stretch) of TMYx 2009-2023 baselines, using 9 CMIP6 GCMs, 4 SSP scenarios (SSP1-2.6, SSP2-4.5, SSP3-7.0, SSP5-8.5), and 4 future horizons (2030, 2050, 2070, 2090). The dataset includes 29 pre-computed building-relevant indicators per file (heating/cooling degree-days, hot days, tropical nights, diurnal temperature range, and others), classified via a three-axis robustness rubric (signal-to-noise ratio, coefficient of variation, directional agreement) documented in the accompanying manuscript. Version note: radiation channel (GHI/DNI/DHI) is carried at baseline values to preserve internal EPW closure (GHI = DNI*cos(theta_z) + DHI); the projected ensemble-mean radiation change over Morocco is demonstrated to be small (~+1.2%, range -0.7% to +2.7% across 8 headline GCMs) and is disclosed as not applied to the deposited files. Canonical derived statistics (baseline indicators, deltas, ensemble statistics, robustness classification) are provided as CSV files alongside the EPW dataset.
