Parametric TAS/SAM Compliance Engine
Parametric TM59 and Part O workflow on EDSL TAS and open-source SAM, on a path to retire £100K+/year of IES VE licensing

Building the instruments that let architects
ask the right questions before it's too late to change anything.
Machine learning surrogates for daylight, overheating, and solar load. Parametric CFD workflows. LiDAR-to-geometry pipelines. If the simulation is the bottleneck, the decisions wait — and that's where good buildings go wrong.

Profile
Climate-responsive evidence at the right moment
I help architecture teams move from intuition to evidence — combining parametric modelling, simulation, and machine learning across daylight, thermal comfort, outdoor comfort, and CFD. The goal is faster, better-informed decisions while the design is still cheap to change.
Summa Cum Laude architect (UNAL Colombia). DGNB-accredited consultant. Transsolar Academy fellow. Currently Senior Computational Developer and ML Specialist at Hoare Lea in London.

Services
What I offer
01
Bioclimatic Design Consulting
Performance-first consulting for design teams, from concept strategy through technical validation. Climate-responsive decisions when they still have budget impact.
Learn more → 02
Daylight, Thermal & CFD Simulation
Evidence-based studies with climate, comfort, and airflow metrics aligned with international standards — TM59, Part O, BCO, EN 17037, ASHRAE 55, DGNB.
Learn more → 03
Parametric Workflow Automation
Custom Grasshopper and Python workflows that reduce repetitive work and unlock faster iteration loops. If you run the same script every project, it should be a button.
