ENVIRONMENTAL
IMPACT INDEX™
The Environmental Impact Index™ (EII) is a smart, data‑driven scoring system that analyzes real local weather conditions to show how quickly algae, salt, sun, and storm moisture will impact your home's exterior surfaces. By combining rainfall, humidity, dew point, UV intensity, storm activity, and coastal exposure, the EII gives you a clear, science‑based understanding of your home's environmental pressure. With this insight, you can plan cleanings at the right time, prevent long‑term damage, and keep your home looking its best year‑round.
HOW THE INDEX WORKS
Algae Pressure Index™
Measures rainfall, humidity, dew point, and UV suppression to predict how fast algae and mold will grow on your surfaces.
Salt Exposure Index™
Calculates salt air concentration from coastal proximity, storm activity, and humidity — the #1 cause of surface corrosion in Florida.
UV / Heat Wear Index™
Tracks UV intensity and temperature to assess how quickly surfaces are bleaching, cracking, and oxidizing.
Storm Moisture Index™
Counts storm days and rainfall accumulation to estimate debris, mold risk, and moisture penetration into surfaces.
Moisture Persistence Index™
Measures how long moisture lingers on surfaces after rain — combining rain days, humidity, dew point, and wind drying. The real driver of algae and mold growth.

DATA SOURCES OVERVIEW
The EII uses a hybrid data model combining real‑time weather inputs and long‑term climate and hazard datasets — ensuring accurate, ZIP‑specific environmental pressure scoring for every index.
Real-Time Weather
Open-Meteo
Live temperature, humidity, dew point, rainfall, UV index, wind speed, and storm activity. Feeds directly into Algae Pressure, UV/Heat Wear, and Storm Moisture indexes.
Long-Term Climate Normals
NOAA
30-year climate normals including rainfall averages, humidity, temperature, UV climatology, storm frequency, hurricane tracks (IBTrACS), and coastal storm surge zones.
Environmental Stressors
EPA
Air quality (PM2.5, ozone), UV exposure trends, climate change indicators, and wet deposition chemistry affecting algae growth and long-term surface degradation.
Hazard & Geographic Exposure
USGS
Flood zones, groundwater and moisture retention, coastal erosion risk, salt exposure hazard class, elevation, and terrain moisture behavior by ZIP code.
Combined Hybrid Model: Open-Meteo → real-time pressure · NOAA → climate normals + storm history · EPA → environmental stressors · USGS → hazard zones + geographic exposure
