For families who want to live near downtown, Houston's affordable housing deficit in and around the Inner Loop is no secret.

For thirty years and counting, Houston-based nonprofit Avenue has confronted this reality by creating affordable housing opportunities and comprehensive community development programs for families in Houston neighborhoods.

"One of our chief objectives is to help stabilize neighborhoods and give opportunities for people to stay in the neighborhoods by providing moderately-priced homes," says Robert Fiederlein, Avenue's senior director of real estate development.

After an audit of Houston's Northline neighborhood revealed the community's affordable housing shortage, the Avenue team began to explore various methods to deliver new construction to the community, through sustainable housing at affordable prices. Research of diverse construction methods led Avenue to the innovative solution of prefabricated family dwellings.

In their effort to find a smart, sustainable alternative to traditional construction, Avenue came across BoxPrefab, an innovative off-site construction company that produces precision-built prefabricated homes from design to completion.

BoxPrefab's sustainable-oriented attributes and efficient processes checked all of Avenue's 'must-have' boxes and the two entities kicked off their partnership with their premier pilot program for modular home development.

"We care a lot about bringing affordability to housing and bringing good designs to affordable housing. We were really excited to work with Avenue because we are really in tune with their mission," says Rame Hruska, BoxPrefab's co-founder. "This is a great solution for homeowners."

This housing solution is not your run-of-the-mill "affordable housing." Besides its sleek finishes and modern look, BoxPrefab's modular home design and construction process is practical and ultra-simplified. Using prefabricated components, the company specializes in building homes in a factory, a controlled environment, instead of building on-site, where the construction process is subject to external variables, like rain, inclement weather, or any labor diversions.

"Reliability is a big factor for our clients. There's so many unknowns and variables, from weather to other various delays, so we can really give people a much more definitive price, time and set quality," says Hruska.

After producing the factory-built components, BoxPrefab then assembles the prefabricated modules on the home's lot. With this streamlined process, BoxPrefab is able to build homes faster and in a more systematic manner, all while reducing waste output and overall cost.

"We have confidence that if we placed higher orders, costs would go down," Fiederlein says. "This could be a way to build less costly affordable housing. Construction costs came out $130 per square foot, which is comparable to the other site-built homes that we're working on right now.

"Another thing we've learned was that we can do it in half the time as a site build," Fiederlein continues. "It takes six to seven months to build a site-built home and we completed this home in just over three months. Russell, with tighter scheduling, said he could've built quicker. We can half the time it would normally take. As you know, time is money."

BoxPrefab's construction process, fiscal efficiency and waste output reduction is exactly what Avenue was looking for in a partner. Together, the two entities successfully completed their pilot program by placing a three-bedroom-two-bathroom prefabricated home on the market in Houston's Northline neighborhood.

"We're really excited about this potential and see it as becoming a much more standard way to build," Hruska says.

Prefabricated building options are considered the future of construction, due to its increased reliability and quality in the construction process, Hruska says. Based on the success of their pilot program, Avenue anticipates investing in more modular housing in the future. BoxPrefab, while Houston-based and focused, has their sights set on expanding regionally, to service more clients with prefabricated solutions, says Russell Hruska, BoxPrefab co-founder.

"Modular is a viable path going forward," Fiederlein says. "It's going to take additional work to get there, but the pilot shows that it's certainly a method that helps to reduce costs…We're confident that it can be the way of delivering affordable housing at lower prices."

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
