Scientists have developed an all-season smart-roof coating that keeps homes warm during the winter and cool during the summer – without consuming natural gas or electricity. Research findings point to a groundbreaking technology that outperforms commercial cool-roof systems in energy savings.
Building operations account for a whopping 35% of U.S. carbon dioxide emissions. A free online tool developed by Berkeley Lab with support from the U.S. Department of Energy’s (DOE) Building Technologies Office (BTO) — the Building Efficiency Targeting Tool for Energy Retrofits (BETTER) — is helping to bring that number down by virtually evaluating buildings for immediate no- and low-cost energy efficiency upgrades.
With a simple stretch, a thin semiconductor material can achieve near 100% light-emission efficiency at all brightness levels. The discovery, reported by scientists at Berkeley Lab and UC Berkeley in the journal Science, has implications for energy-efficient mobile devices and lighting applications.
Since buildings consume 75% of electricity in the U.S., they offer great potential for saving energy and reducing the demands on our rapidly changing electric grid. But how much, where, and through which strategies could better management of building energy use actually impact the electricity system?
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.
Heat waves are becoming a more regular occurrence across the country. Iain Walker, Leader of the Residential Building Systems Group at Berkeley Lab, has suggestions on efficient use of your air conditioner.
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.
A national online energy data management system is transforming how energy retrofit projects implemented by a wide variety of users – including local, state, and federal governments – develop projects and track performance.
After serving four years as Berkeley Lab’s Associate Director for Energy Technologies, Ramamoorthy Ramesh will be returning to his research in ultra low-power electronics while also helping to lead a major Berkeley Lab research initiative in next-generation, energy-efficient microelectronics. This new initiative has been dubbed “Beyond Moore’s Law,” as it seeks the solution to what
