Energy Efficiency – Technologies of the Future

Here are some of the ways Technology will be changing the Energy Efficiency Scenario across the world in Energy Efficiency Sector


We live in an increasingly connected world — the same is true for our homes. New electronic devices and appliances can now be linked to the Internet to provide real-time data that makes it easier to understand and lower energy use. Soon these technologies will be more cost effective and smarter as a result of a project supported by the Energy Department’s Building Technologies Office. New wireless sensors developed at Oak Ridge National Laboratory will boost home energy efficiency through automated control systems for heating and cooling units, lighting and other systems that access data such as outside air and room temperature, humidity, light level and occupancy all at a fraction of a cost of typical wireless sensors you see on the market today. Pacific Northwest National Laboratory, National Renewable Energy Laboratory and Lawrence Berkeley National Laboratory are also developing new protocols and standards that will improve how smart appliances communicate with each other and interact with the electric grid.



The Building Technologies Office is ushering in the next generation of heat pump systems, which warm and cool your home by moving heat from one space to another. These include:

A fuel-fired, multi-function residential heat pump that can reduce primary energy consumption by 30 percent.

A natural gas heat pump and air conditioner that uses an ultra-low-emission combustion burner and other equipment to provide home heating, cooling and hot water.

A low-cost gas heat pump designed to reduce heating costs by 30 to 45 percent compared to conventional gas furnaces and boilers.


The same concept behind heat pump technologies that keep your home comfortable can also be used for another important application: drying your clothes.  Oak Ridge National Laboratory and General Electric are developing a new type of clothes dryer that uses a heat pump cycle to generate hot air needed for drying. The result: a more efficient dryer that has the potential to lower energy consumption by 60 percent compared to conventional ones on the market today.



Oak Ridge National Laboratory and General Electric have teamed up to create a revolutionary new type of refrigerator that uses magnets to create cold, also known as the magnetocaloric effect (lowering or raising the temperature of material by changing the magnetic field).  For the past 100 years, refrigerators have relied on a process called vapor compression that uses coolants which can be harmful to the environment. The new refrigerator is a revolutionary technology that uses a water-based cooling fluid, making it better for the environment and more efficient, which means lower energy bills and less carbon pollution.



Lawrence Berkeley National Laboratory and Pella Windows are working on new highly insulated windows that use sensors and microprocessors to automatically adjust shading based on the amount of available sunlight and the time of day to ensure proper lighting and comfort, saving consumers energy and money.



Insulation is one of the most important ways to reduce your home heating and cooling costs. The Industrial Science & Technology Network is developing new foam insulation made with environmentally friendly and advanced composite materials that ensure heat doesn’t escape from the attic, walls and other areas of the home during cold winter months.



Cool roofs coated with materials containing specialized pigments reflect sunlight and absorb less heat than standard roofs. Expect these types of roof systems to get even “cooler” due to new fluorescent pigments developed by Lawrence Berkeley National Laboratory and PPG Industries that can reflect nearly four times the amount of sunlight of standard pigments. All NYC Buildings in new construction or undergoing certain major renovations are now required to have a green roof under The Climate Mobilization Act and Local Law 94.



Hydromx® is the first commercially viable and academically recognized Efficient Heat Transfer Nanofluid in the World for hydronic closed-loop cooling and heating systems. Hydromx® is a Trade Secret Protected & Certified innovative nano-thermo technology that enables 20-35% energy savings of the associated HVAC bills with a guaranteed maximum of 3 year ROI.

Hydromx® leverages the nanoparticles to increase the speed and the effectiveness of the overall heat transfer process. As a result, the required target temperature is satisfied in a shorter amount of time, thereby requiring significantly less energy versus the conventional heat transfer mediums. Hydromx® has been tested throughout the world and awarded by many industry standard-setting certifications such as NSF International, ASTM, BuildCert, NACE hence proving its compatibility to the latest building and environmental standards.

Hydromx®  is one of the top measures for buildings to improve energy efficiency, offer opportunities to create local jobs, save on energy bills, and cost-effectively reduce greenhouse gas emissions and other harmful pollutants.
