Building-Level Risk Scoring
Seismic retrofit priority grounded in Turkey's Law 6306 and FEMA's rapid screening method. Real İBB air-quality station readings against WHO thresholds, not a citywide average. Heat, green access, and terrain, for every one of 1.2M buildings, automatically.
A score is ready before a consultant would normally reply to the request. Nothing to schedule, nothing to wait weeks on, before we can start on a new city.
Retrofit priority follows the same storey-band and construction-era logic as Turkey's Law 6306 and FEMA's P-154 screening. Air quality follows WHO's guideline thresholds against a real monitoring station, not a flat number applied city-wide.
The scoring doesn't depend on one government's export format. It runs the same way in a new city without renegotiating data access from scratch.
Methodology
No spreadsheet, no site visit, no waiting on a survey. Ask for a building and get an answer in the time it takes to load a page.
What We Score
Retrofit priority blends a real 7.5M earthquake-scenario simulation with İBB's building-age survey, weighting storey count and construction era the same way Turkey's own Law 6306 quick-assessment and FEMA's P-154 rapid screening do — not an arbitrary in-house formula.
Every building is matched to its nearest official İBB air-quality monitoring station and classified against WHO's 2021 guideline thresholds for PM10, cross-checked against European reanalysis data where no station is close enough.
Local climate zone, sky-view factor, tree-canopy cover, distance to green space, elevation, and slope — six independent readings of how a block actually holds heat and drains water, not one proxy standing in for all of them.
How It Works
From raw data to a building-level score, in three steps.
Building footprints, satellite imagery, government surveys, and real monitoring-station data for the target area.
Each building gets a regulation-grounded retrofit priority, a station-based air-quality reading, and heat, green-access, and terrain readings.

FAQ
A seismic retrofit priority grounded in Turkey's Law 6306 and FEMA's rapid screening method, a real air-quality reading from İBB's monitoring stations against WHO thresholds, and heat, green-access, and terrain readings, for every building or 250m grid cell, alongside supporting attributes like height, footprint, and inferred use.
A pilot region we're using to validate the pipeline before expanding. The map itself is open to explore.
Yes. The pipeline isn't tied to one government's data format, so expanding to a new city doesn't mean renegotiating access from scratch. Get in touch if you'd like to be next.
No. Tessera scores existing buildings and neighbourhoods to help prioritise where to act. It doesn't simulate a new design or replace a physics-based CFD tool.
