Dallas Urban Heat Island Effect: Energy, HVAC, and the Path to a Cooler City

What You'll Find in This Report

Dallas is the second-fastest warming major U.S. city. In August 2023 and 2024, NOAA researchers collected over 60,000 temperature measurements across 250 square miles of Dallas — and found that some neighborhoods run 12°F hotter than others at the exact same moment.

This report examines where those hot zones are, why they exist, how they stress the ERCOT grid, and what HVAC technology does — and doesn't — make it worse.
