Heating and cooling buildings is a large part of global energy demand and a significant source of CO2 and greenhouse gas emissions, and in the coming decades the energy demand for heating and cooling – also known as thermal energy – is expected to grow considerably. Scientists and engineers have made many advances in lowering
One hundred and four U.S. companies, schools, governments, and institutions are taking their building energy savings to a new level with the Department of Energy’s Smart Energy Analytics Campaign, a four-year initiative funded through the Building Technologies Office and facilitated by Berkeley Lab.
Buildings account for a whopping 40% of total U.S. energy consumption, and windows are responsible for approximately 10% of that. High thermal performance windows reduce combined heating and cooling energy consumption of typical single family homes in California by up to 50% compared to existing single-pane windows, which are still found in 6.5 million, or
Extreme weather events – such as severe drought, storms, and heat waves – have been forecast to become more commonplace and are already starting to occur. What has been less studied is the impact on energy systems and how communities can avoid costly disruptions, such as partial or total blackouts.
A study by scientists at Berkeley Lab modeled several different types and ages of homes, retail stores, and office buildings in cities across California and the U.S. and found that sunlight-reflecting “cool” exterior walls can save as much or more energy than sunlight-reflecting cool roofs in many places.
Berkeley Lab indoor air experts Brett Singer and Woody Delp advise: stay indoors, consider a mask, limit activities, use air filtration systems, or even build your own.
Berkeley Lab has been awarded more than $4 million by the Department of Energy (DOE) to undertake three projects aimed at improving the energy efficiency of buildings, which account for more than 40 percent of the country’s energy consumption and greenhouse gas emissions.
The U.S. Department of Energy (DOE) wants your ideas on how to make buildings smarter and more energy efficient. As a DOE national lab, Lawrence Berkeley National Laboratory (Berkeley Lab) is partnering with the DOE and private industry on JUMP, an online crowdsourcing community for building technologies. You can submit your ideas on specific technology
It’s estimated that 10 percent of all the energy used in buildings in the U.S. can be attributed to window performance, costing building owners about $50 billion annually, yet the high cost of replacing windows or retrofitting them with an energy efficient coating is a major deterrent. Berkeley Lab researchers are seeking to address this problem with creative chemistry—a polymer heat-reflective coating that can be painted on at one-tenth the cost.
Inaugurated today with help from U.S. Department of Energy Secretary Ernest Moniz, Berkeley Lab’s new General Purpose Laboratory will be devoted to flagship centers in materials sciences and energy storage research, as well as to key biosciences programs. Among the building’s new tenants will be the Berkeley Lab site of the Joint Center for Energy Storage Research, or JCESR, a multi-lab program aimed at achieving revolutionary advances in battery performance.
