Energy Centre, Commercial skyscraper in New Orleans Central Business District, United States.

The Energy Centre is a 39-story, 530-foot (162 m) skyscraper at 1100 Poydras Street, at the corner of South Rampart Street in New Orleans' Central Business District. Designed by HKS, Inc., it is the fourth tallest building in both the city and Louisiana. A four-story parking garage, accessible from Loyola Avenue and South Rampart Street, stands one block upriver.

The Energy Centre was designed by HKS, Inc. In November 2003, Behringer Harvard (TIER REIT) bought the tower for $68.5 million. Hurricane Katrina in August 2005 blew out windows near the top, mostly false windows covering rooftop climate-control systems, and damaged the street-level overhang ceilings; repairs were completed in 2010. Hertz and local investors agreed to buy the building in 2013, and Hertz's unpaid $56.5 million mortgage led to foreclosure in August 2024, with Triangle Capital Group buying it that November.

The Energy Centre sits in the Central Business District of New Orleans, a neighborhood shaped by rapid commercial growth in the 1980s. Walking along the surrounding streets, you pass a mix of towers from that same era, which together give this part of the city its particular look today.

The building sits in the heart of the Central Business District and is easy to reach on foot from most parts of downtown New Orleans. The facade is best seen from the sidewalks and street corners nearby, where you can step back far enough to take in the full height.

The uppermost windows of the building do not open into office space but conceal a large mechanical system hidden behind the facade. From street level they look identical to the windows below, so most people walking past never notice the difference.
