LAUREL, Mississippi (WDAM) – The town of Laurel is currently accepting offers to renovate the historic Oak Park Alumni building.

First built in 1928, it is the last standing structure that was once part of a sprawling Oak Park Vocational High School campus.

Laurel Mayor Johnny Magee said the building is a very important part of the city’s rich history.

“It was laid out like a university campus. There were about 8 different buildings at a time and all the buildings are gone except this one and we want to preserve it and want it to be something people can enjoy, ”Magee said.

“With all the people that come to Laurel, we want to let them go to the Oak Park Alumni building and see what Laurel is all about,” he added.

Oak Park School High School has seen many notable graduates including;

  • Leontyne Price: The first African-American soprano to receive international acclaim.
  • Ralph Boston: In 1960, Boston set a world long jump record previously held by Jesse Owens for 25 years.
  • Dr. Deborrah Hyde: The second African American woman in neurosurgery in the country.

Oak Park High School’s last promotion dates back to 1970.

In February 2021, the Town of Laurel became the owner of the Oak Park Alumni Building, when efforts to restore and rehabilitate the aging structure began.

In July 2021, Laurel City Council approved an ordinance allowing the city to use the services of architect Michael McKinnon for the development of the design for the rehabilitation of the building to the original designs from 1928.

The building is on the Mississippi Department of Archives and History’s list, which will require specific building materials that would have been used in its construction.

Bids will open on October 11 and the cost of the project is expected to be approximately $ 250,000.

The work will include the renovation of the building from the roof to the floor.

The building is placed under the Laurel Parks and Recreation Department and will be available free to the Oak Park Alumni Association.

This article is brought to you thanks to the collaboration of The European Sting with the World Economic Forum.

Author: Jatinder Sidhu, writer, educational content


  • A new report has looked at greenhouse gas emissions over the entire life cycle of a building, including construction and maintenance.
  • He suggests that high-density, low-rise cities such as Paris may be the best at reducing emissions.
  • The net zero goals have largely targeted operational energy consumption, not building-related emissions.

As humanity grapples with the climate crisis, consensus has grown that increasing urban density is a greener way of life.

But according to new research published in the journal Urban sustainability, the most effective way to build a sustainable city is not high-rise buildings, but high-density low-rise buildings.

“Our results show that density is indeed necessary for a growing urban population, but height is not,” said lead author and professor at Edinburgh Napier University, Francesco Pomponi.

“So it looks like the world needs more Paris and less Manhattan – as much as I love New York – in the coming decades.”

Low waist, high density https://www.facebook.com/plugins/video.php?href=facebook.com%2Fworldeconomicforum%2Fvideos%2F1818305771694634% 2F & width = 640 & show_text = false & appId = 1085482764806408 & height = 360

Researchers looked at greenhouse gas (GHG) emissions over the entire life cycle of a building, including the construction and maintenance of structures.

They concluded that tall, high-density buildings increase GHG emissions by 154% compared to low-rise and high-density buildings; while low density housing required 142% more land.

The researchers say that the design of the urban environment has mainly focused on the operational use of energy – which is becoming increasingly efficient – and has not properly taken into account “embedded” energy. It is about “the energy and emissions that are used or generated during the extraction and production of raw materials, the manufacture of building components, the construction and deconstruction of the building and transportation. between each phase ”.

With 2.5 billion more people expected to reside in cities by 2050, the debate over the most efficient way to house people is critical.

Urban areas account for 78% of global energy consumption, and city leaders around the world say they want to take responsibility and do more to reduce carbon emissions.

Transportation and buildings are among the biggest contributors – the construction industry is responsible for around 40% of all carbon emissions. Cities

What is the World Economic Forum doing to promote sustainable urban development?

Cities are responsible for 75% of global greenhouse gas emissions and are home to more than half of the world’s population, a number that will grow to two-thirds by 2050. By becoming greener, cities could contribute to more half of the emission reductions needed to keep global warming below 2 ° C, which would be in line with the Paris Agreement.

To achieve zero net urban emissions by 2050, the World Economic Forum is joining forces with other stakeholders to lead various initiatives to promote sustainable urban development. Here are a few :

To learn more about our initiatives to promote zero carbon cities and see how you can participate in our efforts to facilitate urban transformation, contact us here.

So what are the solutions?

Los Angeles has, as part of California’s Green New Deal policy, adopted guidelines to reduce GHGs from building materials. It is “the first local government to regulate the global warming potential of steel, flat glass and mineral wool purchased by the city”, according to the C40 group of nearly 100 cities engaged in the fight against change climate.

In Norway, the city of Oslo has a zero emission target for municipal construction sites by 2025, extending to all construction sites by 2030. This means that construction equipment will have to switch from fuels. Fossil to Electricity – 98% of Norway’s electricity comes from renewable sources.

The C40 group says it is not enough for buildings to be net zero in terms of operational energy consumption, and has launched a statement to reduce intrinsic emissions by at least 50% for new buildings, renovations major and infrastructure projects by 2030.

Fast action

The costs of not resolving the climate crisis were clearly laid out in the latest report of the Intergovernmental Panel on Climate Change (IPCC). He said “immediate, rapid and large-scale reductions” in GHG emissions would be needed to limit global warming.

Human activity is responsible for the increase in temperature, according to the panel, and lack of action would result in a warming of 1.5 or 2 ° C within 20 years. The effect of this warming is more intense rainfall and flooding, severe coastal flooding and erosion, and more frequent heat waves.

And the highest costs of climate change – both in lives and money – will likely be borne by city dwellers. Globally, 70% of cities are facing climate change and 90% of urban areas are coastal and therefore vulnerable to sea level rise.

Several changes to housing on the Northern Kentucky University campus have taken place this fall semester and are expected to continue next year. Along with a new dormitory which opened on August 19, the existing dormitories are being renovated and new additions have been made to the university accommodation staff.

The new university residence is located in the residential village of Boothe, opposite Norse Hall. It has five floors and 297 beds in a suite style similar to university suites, with each room containing two bedrooms, a shared shower and a shared toilet. The capacity of each suite is four students.

According to Elizabeth Birkenhauer, associate director for planning, design and construction, the first floor includes a fully open common area with a study room, living room and two kitchenettes. Each floor above the first has a desk and a seating area. There is also a yard and charging stations for electric vehicles outside the building.

Floors one through three were open for student access in August at the start of the semester, while floors four and five will be completed in September, Birkenhauer said.

The New Residence Hall was slated for early 2017 and construction began in April 2020, according to a section on the University Housing website with information about the new building. This is the first new housing construction for the university in 17 years since University Suites was completed in 2003.

Aside from the construction of the new residence, renovations to Norse Hall were carried out throughout the summer. According to Dr. Eddie Howard, vice-president of student affairs, these renovations include repainting the walls, replacing the doors and door frames and raising the facades.

“We got to half of the apartments and they should be finished this summer,” Howard said. “We’re going to take the building offline again and bring it to a consistent standard across campus. “

In a campus-wide email on June 29, Howard announced that Callahan Hall will be offline for the 2021-2022 school year to enable a $ 3 million infrastructure improvement project. Scheduled to reopen for the fall semester of 2022, the building is to be fitted with new pipelines and security cameras for added security.

Housing hopes that Callahan Hall will be completely renovated during the summer. Due to lack of sufficient material, they decided to close it for this fall and potentially a whole year.

Obtaining building materials such as steel has been a challenge during the pandemic. “At one point, we thought that the inability to obtain materials would prevent us from delivering the project. [New Residence Hall] on time, ”Howard said.

According to information in the email, students assigned to Callahan Hall have been reassigned to Northern Terrace or other buildings in the residential village of Boothe. Students residing at Northern Terrace will continue to have dining options at the Callahan Bistro.

Other campus facilities will be subject to ongoing upgrading and maintenance. Major areas will be repaired first, followed by a regular program or routine of carpet, patching, etc.

“The goal is not to allow facilities to operate year after year without at least one building maintenance being performed each summer,” Howard said. “We’ve done this in the past, but we’ve taken a haphazard approach. We are now taking a more persistent approach.

Some of NKU’s more recent projects have been done behind the scenes, said Arnie Slaughter, assistant vice president for student affairs. These include new staff additions to University Housing and Residence Living and a new staff structure.

According to Slaughter, a new director for university accommodation has been selected and the residence life coordinators will be in charge of the dormitory buildings, rather than ward directors as before. They will help students who may have questions or need assistance and will increase the overall residential experience.

In early August, NKU began to demand indoor masking for everyone on campus, both unvaccinated and vaccinated.

“Fortunately, as of now, that may change under the regulations of the Centers for Disease Control and Prevention. We will still be able to accommodate students with no occupancy restrictions, ”Slaughter said. “The new director of housing will be involved in making informed decisions based on CDC regulations, the university’s mandate and the state’s mandate.”

As the Delta coronavirus variant drives the number of cases in Kentucky to the red zone, NKU has recently grown COVID-19 decision indicators, which are color coded to show levels of community transmission. Stricter pandemic measures such as social distancing and limited occupancy could be taken based on current indicators.

“What I’m hoping for is to stay in a situation where we can do face-to-face education until the term ends,” Howard said. “We hope that our cases remain low, our isolation and quarantine will remain at zero, that people will mask themselves and remain socially distant. “

For the second month in a row, the price of building materials jumped in August 2021 compared to August 2020, registering an annual increase of 14.37% according to data released by the Statistical Service of Cyprus.

Essential inputs such as steel, cement, sand, stone aggregates and wood-based materials have seen their prices rise over the past year, pushing up overall construction costs.

Compared to August 2020, increases were noted in:

  • Metal products (31.27%) of which iron and steel (47.42%)
  • Wood, insulation materials, chemicals and plastics (12.93%)
  • Electromechanical products (11.02%)
  • Minerals (2.55%) of which Cements (5.36)
  • Mineral products (1.26%)

The Cyprus Statistical Service notes that “the prices of materials used in construction are collected monthly on the basis of a sample of products and suppliers. The reference date for collected prices is the 15th of each month. The prices are evaluated excluding VAT. Data collection is carried out by telephone, fax or e-mail. Material prices are based on actual prices rather than list prices.

In addition to building materials, transportation costs have also increased, with the price of crude oil increasing by around 80% since October 2020. Petroleum is essential to industry as the manufacture of building materials, their transportation and the Operation of construction machinery all depend on oil.

When Rebecca Yang started studying solar building materials about 10 years ago, she feared people would laugh at her.

“I thought it would be great but I was working on my own,” she told AAP.

Professor Yang was captivated by the idea that construction products could be designed to generate energy, but no one in Australia was really talking about it, she says.

Over the past decade things have changed and now there are windows, skylights, facades, siding and roofing products that can capture the sun’s energy while replacing traditional building materials.

Abroad, the FKI Tower in Seoul is clad in movable panels that follow the sun’s rays, and Chicago’s Willis Tower has modernized its photovoltaic glass.

Professor Yang now heads the RMIT Solar Energy Applications Lab, with around 20 researchers, and represents Australia on Building Integrated Photovoltaics (BIPV) at the International Energy Agency.

It maintains a database of over 300 BIPV products – transparent PV windows that can be colored or printed, coatings that can be molded into specific shapes, and PV tiles that snap into place.

There are many unknowns – it’s hard to say what the energy production potential of a BIPV building might be or to estimate what that might mean for entire cities.

“We don’t know what the energy potential of BIPV is in Australia,” she said.

And although these products are used overseas, Australia lags behind Europe and China, despite being a global leader in rooftop solar adoption. , said Professor Yang.

There are only about 20 non-domestic BIPV buildings in Australia and no figures on the number of BIPV homes.

Part of the reason is that many BIPV products are manufactured and safety certified overseas, and there is no testing to prove they meet Australian standards.

BIPV also finds itself stuck between two sectors – renewable energy and construction – which often do not get along.

Fire safety is also a “critical issue” for BIPV products in an industry marked by flammable coatings scandals, although Professor Yang says there are design solutions that mitigate the risk.

Last week, she secured funding from the Victorian Building Authority to study the BIPV fire risk and compare foreign certifications with Australian standards.

The RMIT lab is also hoping for government funding to test various products to see if they can be used locally.

BIPV’s rapid efficiency gains mean that building materials that produce their own energy could be widespread within a few years.

“I think now is the right time, we are all thinking about how to use it,” Professor Yang said.

BOSTON – A state lawmaker wants schools and other public projects to be built with American steel and domestic materials, arguing that foreign competitors are hurting American manufacturers.

The proposal, tabled by Senator Joan Lovely, D-Salem, would require cities and towns to give preference to American manufacturers when purchasing steel, iron and other materials for new buildings and renovations.

Lovely said manufacturers in Canada and other countries can afford to underbid domestic companies for public construction due to a favorable tax structure.

“The cost of doing business here is higher,” she said. “But every time a contract comes to Canada, no one spends money here. Their workers are putting that money back into their economy, and we are on the losing side.”

Lovely said she heard from domestic steelmakers who no longer bother to bid on public projects because they know they won’t get them.

The “Made in America” ​​restrictions, if approved, would apply to public projects exceeding $ 500,000 for “the reconstruction, alteration, repair, improvement or maintenance of a public building or public works. carried out by a public body ”.

Geoff Beckwith, executive director of the Massachusetts Municipal Association, said lawmakers need to be careful about putting in place protectionist policies that could limit the availability of labor and materials and affect costs.

Beckwith said procurement rules in many cities and town halls require them to find the “best and lowest bidder” to reduce costs for taxpayers.

He said a “Made in America” policy could also increase costs for the state, which often shares responsibility for building new schools and public buildings.

“Since there is only a limited amount of public money, one wonders if this would delay the projects,” he said. “And delays are often the biggest cost driver for public projects.”

Supporters of the plan, including Lovely, recognize it will likely increase costs, but argue that the benefits are well worth it.

Lovely said the proposal included exceptions for local governments if the new rules increased the cost of a project too much.

An economic analysis of New England steelmakers suggests that such a requirement would increase the cost of school building materials by about 15%, but it also suggested that this would be “overshadowed” by the increase. of national economic activity.

The trade group said taxpayer-funded school projects in Massachusetts save about $ 15 million per year by purchasing steel from foreign manufacturers.

“However, the result of such savings has resulted in a loss of economic activity of over $ 100 million per year and significant damage to our taxable local steel industry,” the group wrote.

The group said that for every dollar spent on domestically made steel, about $ 1.50 was generated in economic activity.

“The pandemic has taught us that purchasing domestic products is essential to our economic health and our overall well-being,” the group said. “Using steel made by taxpayers on taxpayer funded projects also makes economic sense. “

At least 21 states, including Maine and New Hampshire, have laws that require government preference for materials and products made in the United States.

Thirty-eight states have a sourcing preference for state manufacturers, according to the National Association of State Purchasing Officials, a trade group.

Scott Paul, president of the Alliance for American Manufacturing, said buying Americans “is smart policy that supports middle-class jobs and strengthens both the manufacturing sector and our local communities.”

“Policymakers must maximize the means to ensure that taxpayer dollars are reinvested directly into the workers and businesses that make their products in Massachusetts and the United States,” he said.

BUFFALO, NY (WKBW) – Community Archeology Days, September 17-18, and the following week, September 24-25, were created to educate children about archeology, the African American Heritage Corridor and Black History in Buffalo.

“Black history is American history… we’re all in the same boat,” said Lillie Wiley-Upshaw, president of the Buffalo-Niagara Freedom Station Coalition, one of the organizers of the community event.

The installation and the excavations are entirely open to the public and free of charge. The space offers educational materials, as well as opportunities to use equipment and help with the excavation process. Additionally, tickets for church tours will be available for $ 15, via the Michigan St. Buffalo website here.

Teams from the University of Buffalo’s Archeology Department began their excavation by digging small holes through the grounds on the east side of the church, and will branch out into larger spaces as the days go by.

The goal of the project is to help materialize black history in the region – the African American Heritage Corridor, particularly St. Baptist Church in Michigan, was often the last stop for escaped slaves on the path of Canada in search of freedom. The organizers of the program hope to be able to uncover the story with this act.

So far, the project has only cracked the surface of the excavation – finding construction materials, food waste and ceramics. However, they anticipate more in the coming days.

The site will be open from 10 a.m. to 2 p.m. at 511 Michigan Ave.

With the race for the net zero goal of 2050 and the countdown to COP26 in November 2021, pressure is increasing on the construction industry to find ways to reduce its carbon footprint. Ultimately, this can lead to an urgent review of building materials and construction methods and we take a look at some recent developments below.

Cement

As one of the most versatile materials on the planet and a readily available and inexpensive product, it’s no wonder that after water, concrete is the most widely used substance on earth. Unfortunately, it comes at a high environmental price, given that cement is responsible for 7% of global carbon emissions. As a result, the cement industry is under increasing pressure to find ways to reduce its carbon footprint.

The reaction required to form the produced clinker, used to make cement, requires heat to 1,450 degrees Celsius, compromising one-third of overall emissions, with the remaining two-thirds emitted during calcination. The Mineral Products Association (MPA) suggests that the use of alternative materials can reduce the carbon footprint of cement by 12% by 2050. Two main alternatives to Portland cement (CEM1) are granulated ground blast furnace slag (GGBS). ), which can replace up to 85% of the cement in a mixture of concrete and fly ash, which can replace 30% of CEM1. Manufacturers such as Cemfree offer concrete that uses an alternative geopolymer alkaline activator to CEM1, further reducing the carbon footprint of concrete. However, such concretes do not currently meet British standards. The main concrete manufacturers, such as Cemex with their product “Vertua”, now offer ready-to-use products with varying amounts of these alternatives. But such alternatives are not without limits. The supply of GBBS and fly ash could be an issue and importing these alternatives from more distant countries could shift the balance of environmental benefits of using these alternatives in the first place.

Another possibility for decarbonizing concrete is to use alternative fuels to heat the kiln during cement production. The MPA has set a target of reducing emissions from cement production by 16% by 2050. The MPA study, conducted in 2019, concluded that a combination of 70% biomass, 20% hydrogen and 10% electrical energy could be used to eliminate cement emissions. manufacturing. Currently, Hanson Concrete is testing biomass and hydrogen at its Ribblesdale plant in Lancashire and other manufacturers are testing hydrogen, with Cemex investing £ 18million in a new hydrogen system at its Rugby plant that will be able to operate. 100% hydrogen. Here again, the supply of these alternative fuels poses a problem, the Ribblesdale plant requiring, for example, 0.3 tonnes of hydrogen per hour, and a tanker truck can only transport 0.4 tonnes. To generate enough energy to produce the necessary hydrogen, it would take 60 wind turbines to provide 50% of the fuel needed in Ribblesdale.

Additionally, the cement industry views carbon capture storage (CCS) as the primary solution to the carbon emissions problem, with MPA estimating that 61% of emissions from cement manufacturing will be mitigated by this technology. In addition, there is also the possibility of using the carbon dioxide captured by this process for industrial processes and the fabrication of fuels (carbon capture, use and storage). The UK has created several low-carbon clusters to experiment with CCS technology on an industrial scale, including HyNet North West which will produce, store and distribute hydrogen and capture and store carbon as well. This new technology will take time to take hold and be commercially deployed in cement plants around the world, however, there are good reasons for CCS given the challenges of cement production and the availability of alternatives.

More efficient use of materials

It might sound obvious, but one of the best ways to reduce our carbon footprint is to use fewer materials that can lead to high carbon emissions. A UK-funded research project on decarbonizing precast concrete brought together a range of partners, including precast manufacturer Forterra, design-to-manufacture specialist Akerlof and the Department of Justice (MoJ) to examine the question. The guinea pig of the project was the construction of Wellingborough and Glen Parva prisons. The project revealed that the floor load specifications could be reduced from a slab thickness of 200mm to 160mm and that a concrete mix of 50% GGBS was found to be appropriate. These measures made it possible to reduce the carbon content of the slabs by 30%. These changes had no cost and would be ready to apply to a real project. The Department of Justice will use the low carbon products on the next slice of prisons.

In addition, saving a building from the “wrecking ball” and opting for renovation instead of complete demolition can further reduce the carbon footprint of buildings. One Triton Square would be the new benchmark for the industry to beat when it comes to low carbon retrofits. The original building was designed by Arup Associates and completed in 1998. The main objective of this project was to make it as low in carbon as possible. Several strategies have been used to implement the low carbon initiative, including opting for small improvements in many areas, which is a significant overall benefit. One of the biggest carbon savings, and something rarely done, was taking the faceplate apart, cleaning it, and putting it back in place. An additional 57% space was created by adding three more floors and reducing the atrium. Instead of adding additional columns to strengthen the structure, the original 175 columns have been reinforced. The building has all new services, with the original factory being sold where it could be reused or recycled. The renovation saved 25,000 tonnes of carbon compared to new construction, or 40,000 tonnes over the 20-year lifespan of the building. One Triton Square is said to have set a precedent for other projects.

Modern construction methods

It is not only the materials used that the industry needs to review in order to reduce the sector’s carbon footprint, but the ways in which projects are designed can also be examined. Sustainable design is a critical part of how industry can achieve net zero carbon in the built environment. Nature provides excellent opportunities for solving design problems such as rain gardens as part of sustainable drainage systems (SuDS). The urban heat island effect, whereby solar energy is absorbed by hard surfaces and subsequent re-radiation, causing high temperature in urban environments, can be combated by introducing more landscaping and planting. soft. Reducing the temperature in this way not only improves the quality of environmental spaces, but reduces the need for cooling solutions and therefore energy consumption. The UK Green Building Council (UKGBC) has linked the Nature Based Solutions program to the Climate Adaptation Program and provides several case studies to demonstrate their co-benefits. The Ignition Project, Manchester will help strengthen Manchester’s ability to adapt to the growing impact of climate change by working with nature and using solutions such as rain gardens, street trees, rooftops and green walls. Large developers, such as the Crown Estate, are considering using nature-based solutions as part of their net zero carbon trajectories.

It is clear that the construction industry is starting to take steps towards a low carbon building environment, but with many proposals still in the testing phase, the sector still has a ways to go until these modern construction methods and materials can be deployed. at the much larger scale needed to achieve the goal of net zero. Unfortunately, these developments are likely to continue to be gradual and incremental, as industry experience suggests that new products and methods are often fertile ground for complaints. However, a positive approach to risk allocation and sharing can help manage the problems that arise from new products and methods and help ensure that the path to net zero continues at an urgent pace.

The prospect of colonizing Mars has captivated people ever since space travel became a plausible human endeavor. Our neighboring planet has long been the object of curiosity, and everyone from the country’s top scientists to Elon Musk has speculated on what it would take to build a colony on Mars.

While the notion of a Martian colony conjures up visions of futuristic buildings, wild technological developments, and everything else from a sci-fi movie, the facts are less grandiose. Scientists say that one of the key building blocks on Mars exists in all of us: blood.

It may sound disturbing, but there is solid science to back the theory up. Keep reading to find out how the blood of astronauts can be used to make concrete for a future Martian colony.

The blood, urine, sweat and tears of astronauts could be the key to making concrete on the surface of Mars.

One of the biggest obstacles to building on Mars is said to be transporting land-based building materials to the Red Planet. It would require countless spaceships, a massive crew, and an unfathomable amount of money. So, researchers began to study non-terrestrial materials to build these structures.

What they found was shocking. According to Espace.com, bricks strong enough to build structures could be made by combining Martian soil and a protein found in human blood and a compound found in human sweat, tears or urine: urea.

According to a statement by Aled Roberts, a researcher at the University of Manchester, ENG., Ordinary building materials would not be enough on Mars, and the answer could have been inside of us all this time.

Aled and his fellow researchers at the university took human serum albumin (HSA), a protein commonly found in blood plasma, and mixed it with simulated Martian soil. The HSA acted as a binding agent to create a hard substance potentially rivaling traditional concrete.

The researchers also found that adding urea to the HSA and Martian soil mixture resulted in a binding solution that was stronger than concrete, making it perfect for harsh conditions on Mars. This opens the door to new possibilities for building quickly on Mars.

“If HSA-ERBs were used as a mortar and combined with a sandbag-based construction method, our calculations suggest that each crew member – during a 72-week Mars mission – could produce enough HSA to build habitat space to support an additional astronaut, ”the scientists wrote in a new study. “It could allow the constant expansion of a nascent Martian colony.”

The process raises ethical questions as the constant construction would require daily collection of blood and various other human excrement samples.

“Despite this, we believe that HSA-ERBs could potentially play an important role in a nascent Martian colony, but that they will eventually be replaced by versatile bioreactors or other technologies as they mature,” he added. research team in their report.
