El Paso Energy Building

The El Paso Energy Building is a 502-foot (153 m) tall skyscraper in Houston, Texas. It was completed in 1963 and has 33 floors. It was originally known as the Tenneco Building. It is the 28th tallest building in the city. Because of downtown Houston's diagonal street grid, all four sides of the building are exposed to the sun. The windows are recessed from the frame to control heat and glare from the sun. The footprint of the building is an exact square. Skidmore, Owings & Merrill LLP, the architects of the building, were recognized with an Honor Award from the American Institute of Architects in 1969.
