UMaine experiments with 3D printed floor panels made from recyclable natural materials

2024-08-10T11:00:00-04:00

The U.S. Department of Energy’s Oak Ridge National Laboratory and the University of Maine are leading interesting new engineering research into floor cassettes made using recyclable natural materials that are strong enough to be used in multi-story buildings. Thanks to experiments at UMaine's cutting-edge Advanced Structures and Composites Center (which previously contributed to our coverage of bio-based 3D printed homes), engineers were able to produce a capable model made from polylactic acid and lumber by-products, such as wood flour.

The SM2ART Nfloor cassette components can be 3D printed in roughly two-thirds the time it takes for a typical floor cassette to be factory assembled, thus saving labor costs. Scott Tomlinson, a structural engineer at the Center, shared: "This technology holds a lot of promise for the future of sustainable buildings." The project came together at the initiative of the SHoP offshoot Assembly OSM.

The work was also recently on display as part of the ...

Federal Green Proving Ground program secures $9.6 million to test emerging building technologies

2024-07-24T13:08:00-04:00

Last week marked the announcement of the U.S. General Services Administration’s collaborative Green Proving Ground program with the Department of Energy. The initiative is aimed at producing “real world” evaluations of 17 different emerging technologies that may have a considerable impact on the future of the building industry and architectural design. Funding for the GSA’s latest $9.6 million investment comes from the Inflation Reduction Act.

This year’s program focuses on the following areas: building envelopes and enclosures, healthy and resilient buildings, HVAC systems for commercial buildings, and on-site renewables. The group being evaluated includes everything from heat pumps to geothermal retrofitting solutions and energy-saving ceiling tiles. Select testing will occur at the GSA's Applied Innovation Learning Labs with the first evaluations becoming available in 2026.

The GSA hopes this will ensure a transition to a net-zero emissions federal building portfolio by 2045. On...

Federal 2007 ban on fossil fuels in government-owned buildings finally kicks in

2024-04-28T08:00:00-04:00

Fossil fuels will be banned from new and remodeled federal buildings under a rule finalized by the Department of Energy this week. The rule stems from the Energy Independence and Security Act of 2007 (EISA). Section 433 of that law says new federal buildings and those undergoing major renovations have to phase out "fossil fuel-generated energy consumption" by 2030. But that provision never went into effect because the Energy Department failed to finalize regulations, until now.

All buildings (and vehicles) owned by the U.S. Government are currently under mandate to run on renewable energy by 2050. The EISA mandate was not fully effected until now because the DoE never finalized its regulations, NPR reported a year ago.

Now, the enactment will save an estimated 2 million metric tons of carbon emissions and another 16,000 tons of methane emissions within three decades. That's equal to 4.92 billion kWh of electricity (enough to power a city the size of San Diego for a year) according to standard conversions.

Biden announces $90 million commitment to upgrade building codes nationwide

2023-07-24T14:36:00-04:00

The Biden Administration has recently announced a new $90 million commitment in the form of competitive awards meant to help states and cities in their myriad attempts at mustering updated building codes into the country's patchwork response to climate change.

The funds are being taken from the 2021 Bipartisan Infrastructure Law and supports 27 projects that are all aimed at increasing the energy efficiency, resiliency, and overall performance of buildings in different parts of the country.

In a statement, U.S. Secretary of Energy Jennifer M. Granholm said: “Cutting emissions from buildings across America and ensuring they’re more energy efficient are critical components of President Biden’s plan to tackle the climate crisis and create cleaner and healthier communities. With unprecedented support from the President’s Investing in America agenda, the Department is providing new funding to help cities and states modernize their building codes — lowering energy costs for American famil...

Energy department commits $6 billion to decarbonizing industrial manufacturing

2023-03-13T19:14:00-04:00

The Biden Administration announced a plan to help decarbonize the industrial manufacturing sector through a new $6 billion investment it says will eventually help lower emissions while signaling a newfound demand in the “marketplace for clean products.”

As part of the government’s largest-ever investment into industrial decarbonization, manufacturers of things like concrete, cement, and steel that are known to be heavy polluters will be bolstered by support through the new Industrial Demonstrations Program, which in turn advances grants to early-stage projects in line with the administration’s broader 2050 carbon economy goals.

The White House says grants will cover up to half of the costs for qualifying projects. The funding was made possible as part of the new Inflation Reduction Act and previous Bipartisan Infrastructure Law. Roughly one-third of all domestic carbon emissions come from the industries included in the decarbonization package, according to the Department of Energy (...

U.S. Department of Energy grants $39 million to projects developing carbon-storing buildings

2022-07-21T19:01:00-04:00

The U.S. Department of Energy (DOE) has awarded $39 million to 18 projects dedicated to developing technologies that can transform buildings into net carbon storage structures.

The initiative titled the Harnessing Emissions into Structures Taking Inputs from the Atmosphere (HESTIA) program is being led by the Department of Energy’s (DOE) Advanced Research Projects Agency-Energy (ARPA-E).

The awardees will use the funding to develop alternative building materials and construction techniques. The decarbonization goals for the program align with President Biden’s plan to reach zero emissions by 2050, aiming to increase the total amount of carbon stored in buildings to create carbon sinks.

“This is a unique opportunity for researchers to advance clean energy materials to tackle one of the hardest to decarbonize sectors that is responsible for roughly 10% of total annual emissions in the United States,” U.S. Secretary of Energy Jennifer M. Granholm remarked on the initiative.

The U.S. Department of Energy has invested over a billion dollars into mostly failed carbon capture programs since 2009

2021-12-31T11:08:00-05:00

The Biden administration wants to shove more money into projects that are supposed to capture CO2 emissions from power plants and industrial facilities before they can escape and heat up the planet. But carbon capture technologies that the Department of Energy has already supported in the name of tackling climate change have mostly fallen flat, according to a recent report by the watchdog Government Accountability Office.

According to the report, the Department of Energy (DOE) has invested about $1.1 billion in 11 carbon capture and storage (CCS) demonstration projects since 2009. Of those, only three were ever built, however, the sole participating coal plant shut down in 2020, leaving only two industrial projects in operation.

The U.S. Government Accountability Office (GAO) suggests that Congress consider implementing a mechanism for greater oversight and accountability of DOE CCS demonstration project funding. GAO also recommends that the DOE improve its project selection and negotiation processes and that they should establish more consistent scopes, schedules, and budgets for projects.

U.S. Department of Energy says solar energy has the potential to produce 40% of the nation's electricity by 2035

2021-09-08T13:13:00-04:00

A new study released by the U.S. Department of Energy (DOE) highlights the role solar energy could play in decarbonizing the country’s power grid.

The Solar Futures Study shows that by 2035, solar energy has the potential to power 40% of the nation’s electricity and employ as much as 1.5 million people, without raising electricity prices. This comes following the installation of a record amount of solar in 2020, which currently accounts for 3% of the country’s electricity supply.

The study shows that by 2035, the U.S. would need to quadruple its yearly solar capacity and provide 1,000 GW of power to ensure a renewable-dominant grid. The report goes further to say that by 2050, solar energy could provide 1,600 GW for a zero-carbon grid.

DOE invests $74 million to develop innovations in building and construction

2020-02-18T19:00:00-05:00

Last week the U.S. Department of Energy (DOE) announced its investment of $74 million "for 63 projects to research, develop, and test energy-efficient and flexible building technologies, systems, and construction practices to improve the energy performance of our Nation's buildings and electric grid."

The investment comes in light of the fact that America's buildings use more energy than any other sector in the country, making up 40 percent of total energy use and almost 75 percent of the nation's electricity consumption.

"DOE is accelerating its quest to improve the energy productivity and flexibility of America’s residential and commercial buildings," said Assistant Secretary of Energy Efficiency and Renewable Energy Daniel R Simmons in a statement. "We’re renewing our commitment to develop state-of-the-art building technologies that will empower Americans with more options to enhance buildings performance quickly without disruption to their lives."

Former Texas Governor Rick Perry nominated as Secretary of U.S. Department of Energy

2016-12-15T12:29:00-05:00

President-elect Donald Trump has added another name to his cabinet: former Texas Governor Rick Perry will head the U.S. Department of Energy. The announcement has drawn mixed responses. The oil and gas industry, on the one hand, welcomed the fossil fuel industry-friendly climate change skeptic, and immediately requested that he support increases in natural gas exports. On the other hand, environmentalists and others concerned with accelerating global warming found the choice worrisome, to say the least. A few years ago, Perry proposed abolishing the department altogether, although he also forgot its name once during a debate in a notorious gaffe.

The nomination is the latest addition of an oil industry-friendly climate change skeptic to the cabinet, following the selection of Exxon Mobil Corp’s CEO Rex Tillerson as secretary of state and Oklahoma Attorney General Scott Pruitt, a major opponent of climate change mitigation efforts, as head of the EPA.
