Anew study of the office rental market in the U.S. has revealed Houston has the second highest rate of office vacancies nationwide. In fact, the total square footage of Houston’s empty office space adds up to 1,153 football fields.

The report by Indian service provider Outsource2India discovered 18.6 percent of all office space in Houston is sitting empty, a figure that has grown by 1.6 percent since 2023.

To put the football fields comparison into perspective, that means about 1,522 acres of office space around the city is sitting empty, or nearly 66.30 million square feet.

Rent prices for office space around the U.S. has largely remained unchanged, the report says, except for a very slight uptick in Houston and Austin. Rent prices have gone up just one dollar since the last year to $30 per square foot in Houston, and $44 in Austin.

It's not hard to see why so many offices are sitting empty, especially considering the rising demand (and popularity) of remote and hybrid professions since the COVID-19 pandemic. In a 2020 analysis, Forbes said companies prioritizing the "remote work revolution" saw an increase in teleworker productivity, performance, engagement, retention, and profitability. In 2024, secondary benefits of flexible work environments include smaller carbon footprints, more women in the workplace, reduced operating costs, and more.

Outsource2India suggests major businesses in cities like Houston will need to reimagine their work culture and office spaces in order to compete with flexible work models.

“As remote work continues to reshape workplace dynamics, there is a pressing need for this market to evolve and adapt,” the report said.

After all, Houston commutes aren't getting any easier, and more workers are starting to look for less commute-heavy vocations in suburbs with top job markets.

San Francisco was the only U.S. metro area with a higher office vacancy rate than Houston, at 21.7 percent. However, the actual square footage of empty office space in the city only adds up to 721 football fields, or nearly 952 acres of space.

Elsewhere in Texas, Dallas-Fort Worth has the third highest office vacancy rate in the nation, at 18 percent, followed by Austin with a 16.7 percent vacancy rate. According to the study's football field comparison, the total square footage of empty office space in Dallas and Austin equals 1,328 and 392 football fields, respectively.

The top 10 metro areas with the highest office vacancy rates are:

  • No. 1 – San Francisco, California
  • No. 2 – Houston, Texas
  • No. 3 – Dallas, Texas
  • No. 4 – Austin, Texas
  • No. 5 – Washington, D.C.
  • No. 6 – Chicago, Illinois
  • No. 7 – Denver, Colorado
  • No. 8 – Phoenix, Arizona
  • No. 9 – Los Angeles, California
  • No. 10 – San Jose, California

Outsource2India tracked office rent prices in major U.S. metropolitan areas for 2023 and 2024 to discover the top 10 metro areas with the highest office vacancy rates using data from the National Association of Realtors (NAR).

Houston researcher builds radar to make self-driving cars safer

eyes on the road

A Rice University researcher is giving autonomous vehicles an “extra set of eyes.”

Current autonomous vehicles (AVs) can have an incomplete view of their surroundings, and challenges like pedestrian movement, low-light conditions and adverse weather only compound these visibility limitations.

Kun Woo Cho, a postdoctoral researcher in the lab of Rice professor of electrical and computer engineering Ashutosh Sabharwal, has developed EyeDAR to help address such issues and enhance the vehicles’ sensing accuracy. Her research was supported in part by the National Science Foundation.

The EyeDAR is an orange-sized, low-power, millimeter-wave radar that could be placed at streetlights and intersections. Its design was inspired by that of the human eye. Researchers envision that the low-cost sensors could help ensure that AVs always pick up on emergent obstacles, even when the vehicles are not within proper range for their onboard sensors and when visibility is limited.

“Current automotive sensor systems like cameras and lidar struggle with poor visibility such as you would encounter due to rain or fog or in low-lighting conditions,” Cho said in a news release. “Radar, on the other hand, operates reliably in all weather and lighting conditions and can even see through obstacles.”

Signals from a typical radar system scatter when they encounter an obstacle. Some of the signal is reflected back to the source, but most of it is often lost. In the case of AVs, this means that "pedestrians emerging from behind large vehicles, cars creeping forward at intersections or cyclists approaching at odd angles can easily go unnoticed," according to Rice.

EyeDAR, however, works to capture lost radar reflections, determine their direction and report them back to the AV in a sequence of 0s and 1s.

“Like blinking Morse code,” Cho added. “EyeDAR is a talking sensor⎯it is a first instance of integrating radar sensing and communication functionality in a single design.”

After testing, EyeDAR was able to resolve target directions 200 times faster than conventional radar designs.

While EyeDAR currently targets risks associated with AVs, particularly in high-traffic urban areas, researchers also believe the technology behind it could complement artificial intelligence efforts and be integrated into robots, drones and wearable platforms.

“EyeDAR is an example of what I like to call ‘analog computing,’” Cho added in the release. “Over the past two decades, people have been focusing on the digital and software side of computation, and the analog, hardware side has been lagging behind. I want to explore this overlooked analog design space.”

12 winners named at CERAWeek clean tech pitch competition in Houston

top teams

Twelve teams from around the country, including several from Houston, took home top honors at this year's Energy Venture Day and Pitch Competition at CERAWeek.

The fast-paced event, held March 25, put on by Rice Alliance, Houston Energy Transition Initiative and TEX-E, invited 36 industry startups and five Texas-based student teams focused on driving efficiency and advancements in the energy transition to present 3.5-minute pitches before investors and industry partners during CERAWeek's Agora program.

The competition is a qualifying event for the Startup World Cup, where teams compete for a $1 million investment prize.

PolyJoule won in the Track C competition and was named the overall winner of the pitch event. The Boston-based company will go on to compete in the Startup World Cup held this fall in San Francisco.

PolyJoule was spun out of MIT and is developing conductive polymer battery technology for energy storage.

Rice University's Resonant Thermal Systems won the second-place prize and $15,000 in the student track, known as TEX-E. The team's STREED solution converts high-salinity water into fresh water while recovering valuable minerals.

Teams from the University of Texas won first and second place in the TEX-E competition, bringing home $25,000 and $10,000, respectively. The student winners were:

Companies that pitched in the three industry tracts competed for non-monetary awards. Here are the companies named "most-promising" by the judges:

Track A | Industrial Efficiency & Decarbonization

Track B | Advanced Manufacturing, Materials, & Other Advanced Technologies

  • First: Licube, based in Houston
  • Second: ZettaJoule, based in Houston and Maryland
  • Third: Oleo

Track C | Innovations for Traditional Energy, Electricity, & the Grid

The teams at this year's Energy Venture Day have collectively raised $707 million in funding, according to Rice. They represent six countries and 12 states. See the full list of companies and investor groups that participated here.
