Publishing Interactive Web Dashboards for Honeybee Energy / Daylight Reports with Fast LCP & WCAG 2.2 Compliance

When architectural engineering and sustainability teams export Ladybug / Honeybee annual daylight (UDI / sDA) and EnergyPlus thermal comfort matrices into interactive web dashboards for client delivery or municipal permitting, two frontend engineering challenges frequently arise:

  1. Main-Thread Stalls on Large Sensor Grids:
    Loading 50,000+ spatial sensor points as unchunked JSON into browser SVG/Canvas charts freezes page interactivity. Converting annual hourly arrays into typed Float32Array binary buffers and rendering via instanced WebGL keeps pan/zoom interactions under 16ms.
  2. Colorblind-Safe & WCAG 2.2 AA Accessible Legends:
    Standard rainbow (Jet) false-color palettes fail perceptual uniformity and often violate WCAG 2.2 Level AA contrast requirements when overlaid with numerical text labels. Using perceptually uniform colormaps (Viridis, Cividis) paired with high-contrast badge containers ensures environmental reports pass institutional accessibility audits:
/* High-Contrast Accessible Sensor Tooltip for Environmental Web Reports */
.sensor-metric-badge {
  background-color: #0f172a;
  color: #f8fafc; /* > 15:1 contrast ratio (WCAG AAA) */
  border: 1px solid #38bdf8;
  padding: 4px 8px;
  font-variant-numeric: tabular-nums;
}

Our studio has architected and launched over 60 browser-native CAD, geometry, and WCAG 2.2 accessibility verification tools—available in our live portfolio at Will Sun — 60+ Interactive Web & CAD Engineering Works and Technical Audit & Custom Web Engineering Packages.

How are other environmental design teams packaging interactive Honeybee / Pollination web reports for non-CAD stakeholders?
