Total U.S. building energy use topic of FORNL talk April 8
A distinguished scientist at Oak Ridge National Laboratory who has led the creation of computer models of energy use in nearly every residential and commercial building in the United States will speak Tuesday, April 8, to Friends of ORNL. The models are proving useful for scientists and businesses.
'An energy model of every U.S. building: Science and business uses' is the title of a talk that will be presented to FORNL by Joshua New of the Grid-Interactive Controls Group in the Electrification and Energy Infrastructure Division at ORNL.
In 2024 he received the international R&D 100 'Researcher of the Year' award. In 2016 he won an R&D 100 award (Oscar of Invention) titled, 'Roof Savings Calculator Suite.'
The free presentation is open to the public and will be held at noon at the UT Resource Center, 1201 Oak Ridge Turnpike. Sandwiches, chips, cookies and drinks will be available at 11:15 a.m. at the UT Resource Center for a donation of $10 on a first-come, first-served basis.
To view the virtual presentation, click on the talk title on the www.fornl.org website homepage and then click on the Zoom link near the top of the page describing the lecture. You can view it the next day by clicking on 'Past Talks' on the website's navigation bar.
New is also a joint faculty member in the Electrical Engineering and Computer Science Department and Bredesen Center at the University of Tennessee at Knoxville, where he received the Outstanding Mentor Award in 2024 and his Ph.D. in computer science in 2009.
He has more than 200 peer-reviewed publications. He managed research portfolios for the Building Technologies Office of the U.S. Department of Energy that totaled more than $25 million while he was on loan to the Department of Energy. Over the past 15 years, he led more than 225 projects totaling $350 million.
'More than 125 million residential and commercial buildings in the United States account for 40% of the nation's primary energy use and 73% to 80% of electricity use on the nation's grid,' he said. 'The total energy cost of operating buildings in the United States is $370 billion per year.
'Scientists at ORNL are leveraging high-performance computing resources to simplify building-specific decisions and to provide major industry partners with data necessary to increase deployment of energy-efficient and other building technologies to help meet national goals.
'After five years of effort, the team I led successfully created a model of every U.S. building in 2020. Our building energy model is an open-source tool. We achieved breakthroughs in urban scale energy modeling made possible by artificial intelligence, computer vision and big data processing.
'The digital twin data for 125.7 million U.S. buildings and 122 million models have been made open source. We developed software to help inform best practices for urban-scale energy modeling.'
A digital twin is a virtual copy of a real-world object that accurately reflects its physical counterpart; it is able to be updated with real-time digital data in an effort to determine how to optimize the performance of the real-world object, such as a building.
'In the past five years, I have been working with key partners in several multibillion-dollar industries to enhance the data and models for practical uses in actionable business decisions,' New continued. 'Yet, even more exciting multi-trillion-dollar opportunities exist for resilience, insurance and automated financing of building investments.
'In my talk, I will present some of DOE's national goals, scientific breakthroughs, a roadmap for how to create a digital twin of every building in a nation, ways this information is being used currently, and some thoughts regarding how this new information could help scale up existing industries or create new ones.'
The ORNL data on individual American buildings' energy use, energy demand, emissions and costs has been made publicly available, he said. 'It can be used in scaling up the total effect on the nation of all building operations.'

Ohio Senate, House each passed their ideal budget; What's next?
Jun. 11—An Ohio Senate vote this week finalized its two-year state spending plan that would, among many other things, create a flat 2.75% income tax; push funds to higher performing school districts; and use Ohioans' unclaimed funds to partially fund a new Cleveland Browns stadium. The 23-to-10 Senate vote Wednesday and the subsequent 84-to-1 House vote not to concur with the Senate's changes set up a so-called conference committee — a negotiation between hand-picked members of each chamber that caps off nearly every operating budget process. "This is tradition with budgets with limited exceptions," Senate President Rob McColley, R-Napoleon, told this outlet. "It's usually just the standard process of getting together, working out the differences and figuring out where we're going to end up for the final version." Whatever compromise the GOP-dominated House and Senate chambers agree on then has to be sent to Ohio's Republican governor, who wields line-item veto power and can cross out provisions he doesn't like. Most of the negotiation happens behind closed doors and out of public view, but the major points of contention heading into this conference committee are fairly obvious. Highlights from the Senate's now-confirmed plan compared to the House's plan include: — Creating a flat, 2.75% income tax rate for all Ohioans who earn more than $26,050 annually. The proposal eliminates Ohio's highest tax bracket for earners pulling over $100,000 per year, eliminating over a billion dollars in state tax revenue over a two-year period. — Expanding access to Ohio's "homestead exemption" property tax relief program by increasing the income threshold from $40,000 to $42,000 and allowing slightly more of a qualifying participants' home value to be tax exempt. — Granting county budget commissions the authority to reduce property tax millage "if the commission finds it reasonably necessary or prudent to avoid unnecessary, excessive, or unneeded property tax collections." — Eliminating replacement and substitute property tax levies. — Capping a school district's financial reserves at 50% of the prior year's operating expenses, as opposed to the House-proposed 30% carryover cap. General funds in excess of that 50% cap would then be portioned back out to the property taxpayers of that district. — Directing $600 million of the state's $3.7 billion in unclaimed funds to the Cleveland Browns' new stadium project instead of issuing public bonds as the House proposed. — Requiring school boards to obtain a 2/3 vote from members before putting a property tax levy on the ballot. — Adding $633.9 million more to the state's K-12 public schools than the current biennium, phased in largely through new "performance-based" incentives that will reward high-performing and improving districts with more cash. — Establishing a $100 million set-aside to potentially withhold from state universities that do not come under compliance of the newly-passed Senate Bill 1, which eliminates university-sanctioned diversity, equity and inclusion programs on public campuses. Ohio House Speaker Matt Huffman, R-Lima, told reporters Wednesday that the Senate's school funding plan and flat tax rate will likely be central points of internal discussion as his caucus prepares for negotiations. "We'll have the next two-plus weeks to deal with it," Huffman said. "Our staff and some of the leadership and other folks are set to spend the weekend reviewing these items, so I think there's already discussions going on among a variety of people in different areas about what we may do." But, Huffman said he overall believes that the House and the Senate aren't too far apart on the big stuff — he likes the idea of a flat tax, he's framed the Senate's idea on using unclaimed funds to help the Browns as clever — but pointed to "a lot of very basic policy differences" within the disparate proposals. When asked about his non-negotiables, McColley said he didn't want to reveal too much. "But we're firm believers in some of the big items. The flat tax is something that we feel pretty strongly about," McColley said. "That would be something we're pretty committed to, hopefully we don't get a lot of push back. But other than that, we'll let the process play out." Asked about his non-negotiables, Huffman told reporters, "I'd like to tell you that there is nothing that's non-negotiable, even if somebody says it's non-negotiable."

Bill slashing ticket fees passes Pennsylvania House
HARRISBURG, Pa. (WHTM) — Massive ticket fees may soon be a thing of the past in Pennsylvania. The House passed a bipartisan bill Wednesday that takes aim at the ticket resale market. Known as House Bill 967, it would cap fees ticket resellers can charge at 5% for the buyer and 5% for the seller. Close Thanks for signing up! Watch for us in your inbox. Subscribe Now Reps. Mary Isaacson (D-Philadelphia) and Tom Mehaffie (R-Dauphin) proposed the bill, citing exuberant fees on some of Pennsylvania's favorite pastimes, such as Philadelphia Flyers and Pittsburgh Penguins games. Some fees cost as much as 55%, according to a co-sponsorship memo for the bill. 'These undue and extremely high fees put a burden on ticket prices and only serve as barriers for hardworking Pennsylvanians who want to cheer on their favorite sports team or see their favorite musical artist play,' Rep. Isaacson said. The representatives aren't the ones aiming for ticket fees. Last month, the Federal Trade Commission required ticket sellers to disclose total costs upfront, including fees. Pennsylvania House passes bill to expand AG oversight of health system transactions While he acknowledged companies need to make a profit, Rep. Mehaffie said, 'the reseller and company should not be setting fees so high that they are depriving others of the experience' to attend live events. The bill passed in a 108-95 vote. It now heads to the Senate for consideration. Copyright 2025 Nexstar Media, Inc. All rights reserved. This material may not be published, broadcast, rewritten, or redistributed.

Hegseth wavers on Russia sanctions, says US should not use ‘every tool' to end Ukraine invasion
WASHINGTON — Defense Secretary Pete Hegseth resisted senators' efforts to secure his support for a bipartisan bill that would sanction Russia for its war on Ukraine, telling an Appropriations subcommittee Wednesday that the US should not use 'every tool at our disposal' to pressure Moscow to stop its assault. Asked by Sen. Chris Coons (D-Del.) whether Washington 'should use every tool it has at its disposal, including additional sanctions, to pressure Russia to come to the table to negotiate a just and lasting peace for the war in Ukraine,' Hegseth demurred. 'Senator, every tool at our disposal? No,' he said. 'We have a lot of tools in a lot of places.' 'We should be pursuing a cease-fire and a negotiated resolution to the war in Ukraine at any cost,' Coons responded. ''Peace through strength' means actually using our strength, continuing to support Ukraine, and securing a lasting peace. [Vladimir] Putin will only stop when we stop him.' 4 Defense Secretary Pete Hegseth testified Wednesday at a Senate Appropriations Committee hearing. REUTERS Prior to questioning Hegseth, Coons had talked up Sen. Lindsey Graham (R-SC) and Sen. Richard Blumenthal's (D-Conn.) pending bill to further sanction Russia for its continued resistance to peace in Ukraine. The legislation, backed by 80 senators, would impose sanctions on key Russian officials and economic sectors — and, critically, penalize foreign nations that do business with Moscow. Graham later followed up, urging Hegseth and the administration 'to use that tool to get the attention of China and India.' 'China buys — and India buys — 70% of Russia's oil … If they stop buying cheap Russian oil tomorrow, would that grind Putin's war machine to a halt?' Graham asked, later adding: 'We have an ability, through legislation, to get China and India's attention [and say] that if you keep buying cheap Russian oil to empower Putin to kill Ukrainian children, you're going to lose access to our markets. 'We're not going to evict every Russian from Ukraine, I'm a practical guy,' Graham added. 'But we got to end this war so we don't entice China to take Taiwan, and we don't encourage Iran to think we're just all talk [about] stopping their nuclear ambitions.' 4 Sen. Lindsey Graham (R-S.C.) questions Secretary of Defense Pete Hegseth during a Senate Committee on Appropriations subcommittee hearing to examine proposed budget estimates for fiscal year 2026 for the Department of Defense. AP On Friday, the Wall Street Journal reported that the White House was quietly pushing Graham to water down the bill by allowing waivers to exempt certain people and entities from sanctions and to 'remove the mandatory nature' of the legislation. A White House official told the outlet that the Constitution 'vests the president with the authority to conduct diplomacy with foreign nations.' 'Any sanction package must provide complete flexibility for the president to continue to pursue his desired foreign policy,' they added. Hegseth did admit Wednesday that Russia is the 'aggressor' in Ukraine and that Chinese President Xi Jinping wants Moscow to 'win' the conflict. However, the secretary declined to answer Sen. Mitch McConnell's (R-Ky.) question about 'which side' he wanted to win the war. 'As we've said time and time again, this president is committed to peace in that conflict,' Hegseth said. 'Ultimately, peace serves our national interests, and we think the interests of both parties, even if that outcome will not be preferable to many in this room and many in our country.' 4 Defense Secretary Pete Hegseth (R) greets Chairman of the Joint Chiefs of Staff Air Force Gen. Dan Caine before testifying during a hearing with the Senate Appropriations Committee on June 11. Getty Images McConnell pushed further, noting that the Russians 'don't seem to be too interested' in peace talks. The former Senate GOP leader also alleged that NATO partners increasing their defense spending at Trump's behest are now wondering 'whether we're in the midst of brokering what appears to be allowing the Russians to define victory.' 'I think victory is defined by the people that have to live there, the Ukrainians,' he said. 'And I don't think they're going to ever conclude that victory means basically adopting the Russian views on all this. ' Hegseth responded that 'no one's adopting views,' but added that the upcoming National Defense Authorization Act does not include funding of weapons for Ukraine because 'the budget reflects the reality that Europe needs to step up more for the defense of its own continent, and President Trump deserves the credit for that.' 4 Ranking member Sen. Chris Coons (D-Del.) speaks with subcommittee Chairman Sen. Mitch McConnell (R-KY) during a hearing with the Senate Appropriations Committee on June 11, 2025. Getty Images McConnell agreed, noting that he had 'the same complaints' about the Biden administration not pushing hard enough for Europe to fund Ukraine's defense. Still, the Kentuckian insisted that by not standing foursquare behind the Kyiv government, 'it seems to me pretty obvious that America's reputation is on the line.' 'Will we defend democratic allies against authoritarian aggressors?' McConnell asked. 'That's the international concern that I have about this, and I think a number of my fellow members share that view.'
