Plug and process loads (PPLs) consume about one-third of primary energy in U.S. commercial buildings. PPL efficiency solutions have become relevant in achieving energy cost savings and improvement in building performance; however, their broad implementation has been stunted by a number of myths.
Small businesses are a vital part of America’s growing economy, but they face many challenges bringing their innovative ideas and products to market. When pursuing innovation, many small businesses cannot secure sufficient funding to support research and development (R&D) of new technologies and services.
Fellows in the Emerging Technologies (ET) program of the Building Technologies Office (BTO) are the Energy Department’s next generation of engineers and scientists, tasked with bringing fresh ideas and new perspectives to the program’s building energy efficiency research and development portfolio.
As part of the Obama Administration’s effort to cut energy waste in the nation’s university buildings and facilities, today the Energy Department’s Better Buildings Challenge program recognized University of California, Berkeley for its leadership in energy efficiency. The University achieved 65 percent energy savings at its Jacobs Hall facility, the College of Engineering’s interdisciplinary hub where students and teachers from across the university work at the intersection of design and technology.
In order to consistently exchange information on building characteristics and energy use data between tools and databases, several organizations have signed up to use the Building Energy Data Exchange Specification (BEDES) in their software applications, totaling 16 BEDES-compliant products since inception.
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).
