| Problem | Likely Cause | Solution |

| Simulation crashes during shading calculation | Too many buildings (n>2000) | Reduce to representative clusters (e.g., archetype-based) |
| Unrealistically low cooling loads | Overestimated shading | Check sun angles and surrounding building heights |
| Out of memory | Storing full hourly results for all zones | Use --output-format parquet and filter to thermal zones |
| Microclimate temperature jumps >5°C | Missing anthropogenic heat | Add --waste-heat-factor 0.15 (15% of elec load) |

URBiN4HD is an experimental neurotechnology initiative (or project name) focused on developing urban-scale brain–health interventions and infrastructure. It explores integrating wearable neurotech, city data, and public-health frameworks to monitor, support, and potentially predict neurological health outcomes across populations. Key themes to cover in a post: If no public repo exists: Contact the developers (e
