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: Attoseconds break into atomic interior

A newly developed laser technology has enabled physicists in the Laboratory for Attosecond Physics (jointly run by LMU Munich and the Max Planck Institute of Quantum Optics) to generate attosecond bursts of high-energy photons of unprecedented intensity. This has made it possible to observe the interaction of multiple photons in a single such pulse with electrons in the inner orbital shell of an atom.

In order to observe the ultrafast electron motion in the inner shells of atoms with short light pulses, the pulses must not only be ultrashort, but very...

Im Focus: Good vibrations feel the force

A group of researchers led by Andrea Cavalleri at the Max Planck Institute for Structure and Dynamics of Matter (MPSD) in Hamburg has demonstrated a new method enabling precise measurements of the interatomic forces that hold crystalline solids together. The paper Probing the Interatomic Potential of Solids by Strong-Field Nonlinear Phononics, published online in Nature, explains how a terahertz-frequency laser pulse can drive very large deformations of the crystal.

By measuring the highly unusual atomic trajectories under extreme electromagnetic transients, the MPSD group could reconstruct how rigid the atomic bonds are...

For the first time, a team of researchers at the Max-Planck Institute (MPI) for Polymer Research in Mainz, Germany, has succeeded in making an integrated circuit (IC) from just a monolayer of a semiconducting polymer via a bottom-up, self-assembly approach.

In the self-assembly process, the semiconducting polymer arranges itself into an ordered monolayer in a transistor. The transistors are binary switches used...
