Innovative, Lower Cost Sensors and Controls Yield Better Energy Efficiency

03.03.2015

Regulating comfort in small commercial buildings could become more efficient and less expensive thanks to an innovative low-cost wireless sensor technology being developed by researchers at the Department of Energy’s Oak Ridge National Laboratory.

Buildings are responsible for about 40 percent of the energy consumed in the United States. Studies indicate that advanced sensors and controls have the potential to reduce the energy consumption of buildings by 20-30 percent.


ORNL

ORNL researchers are experimenting with additive roll-to-roll manufacturing techniques to develop low-cost wireless sensors. ORNL’s Pooran Joshi shows how the process enables electronics components to be printed on flexible plastic substrates.

“It is widely accepted that energy-consuming systems such as heating, ventilating, and air conditioning (HVAC) units in buildings are under, or poorly, controlled causing them to waste energy,” said Patrick Hughes, director of ORNL’s Building Technologies Program. “Buildings could increase their energy efficiency if control systems had access to additional information.”

Collecting data such as outside air and room temperature, humidity, light level, occupancy and pollutants is currently cost prohibitive, whether the information is gathered by inexpensive conventional sensors that must be wired, or by using today’s expensive $150-300 per node wireless sensors.

ORNL’s new wireless sensor prototype could reduce costs to $1-10 per node by leveraging advanced manufacturing techniques such as additive roll-to-roll manufacturing. This process enables electronics components like circuits, sensors, antennae, and photovoltaic cells and batteries to be printed on flexible plastic substrates (base materials). The nodes can be installed without wires using a peel-and-stick adhesive backing.

“If commercially available at the target price point, there would be endless application possibilities where the installed cost to improve the control of energy-consuming systems would pay for itself through lower utility bills in only a few years,” Hughes said.

The ultra-low power smart sensors collect and send data to a receiver, which can capture data from many different peel-and-stick nodes and provide the information to the energy-consuming system. The more information received, the better the building’s energy management.

Both new construction and retrofitted buildings can benefit from ORNL’s smart sensors.

“This technology provides the information that enables ongoing continuous commissioning, fault detection and diagnosis, and service organization notifications when needed, ensuring optimal building system operations throughout their service life,” said ORNL’s Teja Kuruganti, principal investigator on the low-cost wireless sensors project.

ORNL is currently in negotiations to establish a cooperative research and development agreement with a premier international electronics manufacturer to make the low-cost wireless sensors commercially available.

This project is sponsored by DOE’s Building Technologies Office in DOE’s Office of Energy Efficiency and Renewable Energy.

UT-Battelle manages ORNL for the Department of Energy’s Office of Science. The Office of Science is the single largest supporter of basic research in the physical sciences in the United States, and is working to address some of the most pressing challenges of our time.

Im Focus: Deep inside Galaxy M87

The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.

Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Im Focus: Microprocessors based on a layer of just three atoms

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.

Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...

Im Focus: Glacier bacteria’s contribution to carbon cycling

Glaciers might seem rather inhospitable environments. However, they are home to a diverse and vibrant microbial community. It’s becoming increasingly clear that they play a bigger role in the carbon cycle than previously thought.

A new study, now published in the journal Nature Geoscience, shows how microbial communities in melting glaciers contribute to the Earth’s carbon cycle, a...
