The façade as a circuit: metamaterials move light, sound and heat by geometry, not bulk
Metamaterials let a façade bend light, sound and heat by geometry, not bulk. The systems read: where the unit cell becomes the spec, and what it depends on.
AionDB Folds Three Databases Into One Rust Engine — Draw Your Dependency Graph First
AionDB folds Postgres-wire SQL, Cypher graphs, and HNSW vector search into one Rust process. What the convergence means for AEC archives and PAZ-GPT.
Your Face Is a Façade: What Apple's Personas Reveal About Gaussian Splatting
Apple's Vision Pro Personas use Gaussian splatting. PAZ unpacks the geometry behind it — the R·S·Sᵀ·Rᵀ covariance — and what it means for AEC survey.
The Week the Dependency Graph Came Due: Spare Paths, Open Files, and Who Resets It at 2am
Week 2026-W26 recap: Sakana Fugu's spare path, Neural CAD vs CADAM's openable files, and the single points of failure hiding in your AEC stack.
Zoning as Code: When a Masterplan Recomputes Its Own Envelopes
How parametric urbanism turns setbacks, FAR and sunlight into executable rules — a masterplan that recomputes its own envelopes and street life.
Two days at PAZ Central: the KI Sommer Camp returns, tighter and hands-on
PAZ Academy's KI Sommer Camp returns 2–3 July 2026 at PAZ Central, Zürich: a two-day, hands-on AI workflow camp for architects and AEC teams.
The wave equation, sliced four ways: a faster solver for seismic and acoustic FE
A new space-time sparse-grid method makes the wave equation embarrassingly parallel — what it means for seismic, acoustic and vibration FE on an architect's desk.
The blurry-mean trap: why your AV (and BIM) model can score well and still be wrong
An arXiv diffusion world model shows SSIM and cosine metrics reward useless blur — the evaluation lesson every AEC ML pipeline needs. Plus a 3-line Python check.
Adam's CADAM Turns a Sentence Into Editable OpenSCAD — In Your Browser
Adam's CADAM (YC W25) turns plain English into parametric, browser-based OpenSCAD you can export, edit, and Git. A hands-on PAZ tutorial for AEC makers.
I Keep My Keys in My Walls: A Three-Class Scanner That Stops Crying Wolf
A new CNN-CodeBERT framework separates real credentials from placeholders, cutting false alarms 33% — and why your AEC studio's repos need it now.
