Weather Normalization

Is Your Building Getting Better, or Was It Just a Mild Winter?

Energy consumption changes with the weather. VITALITY normalizes for temperature — heating degree days, cooling degree days — so you can see actual building performance improvements, not just seasonal noise.

How Weather Normalization Works

We correlate your building's consumption with local weather data — heating degree days (HDD), cooling degree days (CDD), and temperature extremes — to isolate weather-dependent usage from base load.

Local Weather Data

VITALITY pulls weather data for your building's exact location. Not regional averages — actual conditions at your property.

HDD/CDD Regression

Statistical modeling that separates temperature-driven consumption from base load, operational changes, and equipment efficiency.

Normalized Comparisons

Compare this year to last year on equal footing. Compare buildings in different climates fairly. Weather is no longer an excuse.

Why Normalization Matters

Prove ROI on Upgrades

Installed new insulation? Upgraded HVAC? Weather normalization shows the real impact — stripped of seasonal noise.

Fair Building Comparisons

Compare a Phoenix building to a Minneapolis building on equal terms. Normalization levels the playing field across climates.

Regulatory Compliance

Many building performance standards require weather-normalized data for compliance reporting. VITALITY generates it automatically.
