Buildings in the U.S. consume 38.5 quads of energy annually, of which nearly half is used for heating, ventilation, air conditioning and refrigeration (HVAC&R). Traditional HVAC&R systems rely on a process called vapor compression to cool and heat our buildings, using a compressor to circulate liquid refrigerants, typically hydrofluorocarbons (HFC). HFCs are hundreds to thousands of times more potent than carbon dioxide and can last for centuries when released into the atmosphere.
The United States and India have a long and successful strategic partnership in the energy sector. In November 2009, the United States and India launched the Partnership to Advance Clean Energy (PACE), which is working to accelerate inclusive, low carbon growth by supporting research and deployment of clean energy technologies. Under PACE-R (research), the U.S. and India support research in solar energy, building energy efficiency, advanced biofuels, smart grid, and energy storage.
As part of Smart Cities Week, the White House recently announced a new Energy Department-led Smart Energy Analytics Campaign to encourage the use of cost-effective, energy-saving building analytics platforms – also known as energy management information systems technologies (EMIS) – in commercial buildings nationwide, and refine best practices.
The U.S. Department of Energy (DOE) today recognized 34 of the nation's leading builders at the 2016 Housing Innovation Awards during the Energy and Environmental Building Alliance's Excellence in Building Conference in Dallas, Texas.
As part of the Obama Administration's effort to cut energy waste in the nation's buildings and facilities, today the U.S. Department of Energy is launching the Better Buildings Smart Labs Accelerator to advance energy efficiency in laboratory buildings owned and operated by universities, corporations, national laboratories, hospitals, and federal agencies.
The U.S. Department of Energy is launching the Better Communities Alliance (BCA), a new collaborative effort among 60 local governments, philanthropies, nonprofit organizations, and leading private companies to accelerate local clean energy progress across the country. The BCA was announced today by the White House during Smart Cities Week.
Reducing air conditioning energy use by using new materials to enhance the cooling effects from outer space may not be such a far-out idea. In a simulation study, PNNL researchers found that daytime radiative cooling—the physical process by which an object loses heat to another object of lower temperature—could reduce energy consumption of an office building by 30 to 50 percent.
The Energy Department is supporting efforts to phase down the global use of climate-change causing hydrofluorocarbons (HFCs) used in cooling and refrigeration. These chemicals can be thousands of times more potent than carbon dioxide and last for centuries when released into the atmosphere.
At the Secretarial Honor and Presidential Rank Awards, the DOE Building Technologies Office’s Appliance and Equipment Standards (ASP) Program won a Secretary of Energy Achievement Award, under the leadership of John Cymbalsky, for its work last year on finalizing a record 13 standards, including the largest energy-saving standard in U.S. history. Award-winning teams must have demonstrated cooperation and teamwork en-route to accomplishing significant achievements on behalf of DOE and attaining their goals.
The Energy Department’s Building Performance Database (BPD), the nation’s largest dataset of energy-related building characteristics, has expanded to include data from over 950,000 commercial and residential buildings.
A few months ago, we discussed what building energy codes are and more recently we looked at how they are developed and what role the U.S. Department of Energy (DOE) plays in that process. Today, we are going to take a look into the next step—how codes are adopted.
Thanks in part to DOE’s Buildings Technologies Office (BTO) and its network of research and industry partners, many appliances and building technologies, such as air conditioning and solid-state lighting, have, and continue to, become more and more energy efficient, providing the same level of services or better at a lower energy cost.
Some metals do a remarkable thing when they’re placed within a magnetic field: They heat up. Remove the magnetic field, and they grow cold. It’s not difficult to see how this heating and cooling, known as the magnetocaloric effect, might be put to good use.
John Cymbalsky, program manager of Appliance and Equipment Standards within DOE’s Building Technologies Office (BTO), was recently recognized as a “Champion of Energy Efficiency” by the American Council for an Energy-Efficient Economy (ACEEE).
I recently spoke with two distinct audiences about the importance of buildings in the U.S. energy space. Both the FEMP Energy Exchange conference and a group hosted by the Alliance to Save Energy had roomfuls of energy savvy professionals, many – but I suspect not all – of whom recognize the scope of opportunities the U.S. buildings sector offers for reducing energy consumption and greenhouse gas emissions.
At the Energy Exchange 2016 earlier this month, the Department of Energy’s (DOE) Federal Energy Management Program (FEMP) and Building Technologies Office (BTO) announced the winner of the FEMP JUMP technology challenge to identify underutilized new or recently commercialized building technology solutions.
The U.S. Department of Energy (DOE) has selected 43 small businesses, including three businesses working on buildings-related issues, to work directly with DOE national labs to accelerate the transformation toward a clean energy economy. Selected businesses will be afforded access to world-class laboratory resources to help move these innovative technologies into the market faster.
Driving the reduction of energy consumption and greenhouse gas (GHG) emissions through efficiency projects in the retail sector can be difficult, particularly when many energy managers lack awareness of financing mechanisms available to them to fund their projects.
