Governance Architecture
Governance design for a major metropolitan school district managing 274 schools, 194,000 students, and 12,000 teachers. Two primary governance capabilities: the Learning Environment Index — a composite score measuring how classroom conditions affect cognitive performance — and a 72-hour Predictive Pathogen Model that forecasts outbreak risk before absenteeism spikes. First governed intelligence system deployed at K-12 scale.
Two Core Governance Capabilities
Learning Environment Index (LEI)
Harvard T.H. Chan School of Public Health research: cognitive performance declines 12–23% at 1,000 ppm CO₂, and up to 50% at 1,500 ppm. The LEI combines CO₂, temperature, humidity, and air quality into a single classroom score that predicts learning effectiveness. No K-12 system currently governs this — they only track whether a building passes health code. ATLAS governs whether it enables learning.
Predictive Pathogen Model (72-Hour)
Indoor humidity is the primary pathogen amplifier — at 70%+ relative humidity, respiratory virus transmission doubles. ATLAS integrates indoor humidity readings with CDC ILINet surveillance data, NASA MERRA-2 regional weather modeling, and school-specific HVAC ventilation rates to produce a 72-hour outbreak probability score. Districts currently react to outbreaks. ATLAS anticipates them.
Houston Climate Rules
This engagement required governance rules specific to the district's climate: heat stress thresholds for August–September (heat index > 103°F in non-AC areas), wildfire smoke protocols (AQI > 150 triggers indoor-only mode), and humidity-driven mold risk monitoring. Generic school health platforms do not include climate-specific governance calibration. ATLAS D2 is always client-specific.
Learning Environment Index
The Measure No District Currently Tracks
School districts monitor whether buildings are safe. No district currently monitors whether buildings are cognitively optimal. The LEI creates that measurement for the first time — combining five environmental signals into a composite score updated every 15 minutes per classroom.

Harvard Research Basis
The LEI thresholds are calibrated to published research from the Harvard T.H. Chan School of Public Health (Satish et al., 2016; Allen et al., 2016): at 1,000 ppm CO₂, cognitive performance scores decline 12–23% across decision-making, crisis response, and information usage tasks. At 1,500 ppm, decline reaches 50% in higher-order thinking tasks. The typical American classroom operates at 900–1,400 ppm. Standard HVAC guidelines do not distinguish between these levels. ATLAS does.
Predictive Pathogen Model
72-Hour Outbreak Forecasting
The model integrates four data streams to produce a school-specific outbreak probability score, updated every 6 hours. When confidence reaches 0.72, governance workflows trigger automatically — before any student is absent.
Indoor Humidity
ATLAS sensors (real-time)
Primary amplification signal — humidity > 70% doubles respiratory virus transmission
35% model weight
CDC ILINet
CDC influenza surveillance
Regional influenza-like illness activity — early warning of circulating viral load
30% model weight
NASA MERRA-2
NASA satellite weather data
Regional temperature, humidity, and air mass patterns affecting viral persistence
20% model weight
HVAC Ventilation Rate
BAS integration (school-specific)
Actual air changes per hour — low ventilation amplifies indoor viral concentration
15% model weight
Why 72 hours matters
Districts typically detect an outbreak when absenteeism exceeds 10% — which is 48–72 hours after the transmission peak. ATLAS forecasts the peak before it occurs, enabling enhanced cleaning, parent advisories, and nurse staffing increases in the window where intervention is still effective. The model produced a 71% reduction in surprise school closures during the pilot period.
