Samantha Schild took to Instagram on Feb. 3, after Quinnipiac University announced its plan to build a new South Quad between Tator Hall and the College of Arts and Sciences. 

“I’m sorry, this is a joke right?” wrote Schild, the secretary of Students for Environmental Action, on the Instagram Story.

The university plans to build two new academic buildings and a residence hall by 2024. The project, which will cost $244 million, includes a new School of Business, a 417-bed residence hall and a general academic building.

However, students said the problem is that this involves destruction and disturbance to the campus’ woodsy pine grove path. 

“Tearing down the pine grove to build three new buildings and claiming to be a school focused on sustainability in eco-consciousness is hypocrisy at its finest,” Schild, a third-year 3+1 biology major, wrote in the post, which expired after 24 hours. 

As a member of the Sustainability Committee, Schild said she is not aware of the university seeking any input from students before announcing its building plan, despite the commitment to “build relationships with Students for Environmental Action and other student groups” noted in an October 2020 Sustainability Report. 

The university opened a Blackboard online community forum in 2020 for community members to voice concerns about issues of sustainability. An update from the office of President Judy Olian assures that the university has held “a series of town hall forums, meetings with stakeholders and a review of (the) best practices” for its upcoming plans.  

“Why have a Sustainability Committee … if you aren’t going to include them in these types of pivotal decisions?” Schild told The Chronicle. 

The university has made significant promises to be ecologically conscious. In the October report, Olian laid out a plan for a Sustainability Committee with the vision of establishing sustainability in “learning, living and leading.” 

“A sustainable living environment necessitates campus layouts that fully integrate with surrounding natural environments,” the university wrote in the report. “This requires the integration of ‘natural areas’ into campus design.” 

Quinnipiac expressed that it hopes to gain Leadership in Energy and Environmental Design Certification in accordance with its sustainability plan and is considering building a green roof as a part of the new construction and utilizing solar power during building. A green roof is a roof covered in vegetation, used to absorb rainwater, encourage native wildlife and provide insulation. The university also plans to incorporate sustainable energy by housing a central energy plant under the new academic building set to hold the School of Business. 

“It is wonderful that the university has committed to making all three buildings LEED certified,” said Sam Edwards, professor of legal studies and co-chair of the Sustainability Committee. “This is a significant commitment to sustainability… They include things such as location and transportation, materials and resources, water efficiency, energy and atmosphere, sustainable sites and indoor air quality.” 

Schild said these commitments are not nearly sufficient enough to establish Quinnipiac’s presence as an environmentally friendly university, especially not when getting there involves the destruction of existing natural spaces. 

“‘(Exploring) the installation of a green roof with live vegetation and/or solar panels for energy generation’ sounds to me like a weak effort to address the issues the administration knew they were causing,” Schild said. “Implementing these types of changes should start with the numerous academic buildings and residence halls we already have.” 

However, Edwards said that the green roof will be a suitable location to conduct sustainability research. 

“For me, the bottom line is that if the university is going to build buildings, it is great that they will be built to external sustainability standards,” Edwards said. 

Schild listed newly renovated residence halls Perlroth, Larson, Troup and Complex as better suggestions for the location of a green roof and solar panels, rather than further construction. She said that the university needs to preserve its natural resources, especially those that are in the process of repairing themselves from climatary damage. 

“The Pine Grove has undergone a lot of damage from storms and tornadoes in the past few years, a testament to a changing climate with more and more extremes,” Schild said. “But the drive that the administration feels to tear down such a beloved part of campus is incredibly disheartening.” 

Schild said that the pine grove helps students feel connected to nature, and that it is not enough to have Sleeping Giant State Park across the street. In addition, Schild said that the construction will lead to the extermination of native plants and insects from the area. 

“No more sweet songs in the mornings that you can hear all the way on the Quad,” Schild said about the campus environment when the building comes to fruition. “So much more will be lost than just the beautiful, towering trees.”

Cameron Davignon, a senior finance major, said that he is excited for the new buildings. 

“I’m honestly all for it,” Davignon said. “I just wish I was still going to be here to see the new School of Business.” 

Davignon, who was a member of the Residence Hall Planning Committee last summer, said he discussed the issue of knocking down the pine grove with Vice President for Facilities and Capital Planning Sal Filardi. 

“Sal Filardi said they’ll plant multiples of what they cut down, so assuming they do that, I think (cutting down the trees is) fine,” Davignon said. 

Though some students expressed on a Quinnipiac Barstool Instagram post after the announcement that they would rather see the university spend money on different projects, Davignon said the South Quad is an acceptable investment. 

“It’s good to see (the university) spending the $750 million endowment on expansion because they’re usually hesitant to spend it, in my opinion,” Davignon said. 

Justin Taddeo, a sophomore public relations major, was more concerned about the usage of the university’s space than the sustainability of the project. He said that Quinnipiac should focus on additional parking rather than creating more academic and residential buildings. However, he agreed that it is a good investment in the long run. 

“I think paying for more memorable events or buying supplies for certain clubs or departments is something they could do right now to help current students,” Taddeo said about the university’s finances. 

As far as the Pine Grove, Taddeo said that though he can see the concern, the construction does not bother him “because we have all of Sleeping Giant to enjoy.” 

In an Instagram Story poll from The Quinnipiac Chronicle, 39 respondents said they support the plans for the South Quad, while 46 said they did not.

(The Daily Dish) Jake Stone with Zerorez joined Nicea to talk about their processes and also all of their current specials they’re offering for February! Hurry and get it booked before it’s too late!

You probably feel the same about your rugs or carpet right now after most of the winter season, dirty and dingy. Zerorez uses a substance called Powered Water to clean and leave zero residues, something other cleaners cannot promise.

Zerorez uses its proprietary substance called Powered Water. It is created by running it through an electrolysis process, altering the molecule. It becomes slick to the touch and has all the cleaning properties of soap, but none of the side effects. Soap can be difficult to rinse out and often leaves a sticky residue on the carpet. Powered Water eliminates the need for soap and dries just like water, leaving nothing behind.

Most cleaners use soaps and detergents are extremely challenging to get out. They can be taken out, but you must rinse, rinse, rinse, rinse and repeat. It’s a long process to remove all the chemicals left in carpet.  Even if you can remove the soaps and detergent, you’re then left with the carpet sopping wet. This can bring other problems potentially creating mold in the backing of your carpet or the pad. Once Powered Water dries the carpet goes back to neutral, it can’t harm you.

After 20-30 minutes maximum, your carpet and rug will look better than new!

Also, did you know the quality of the air in your home can be as much as 5x -10x worse than the air outdoors?

The list of potential allergens and pathogens in your ductwork is long: bacteria, kitchen grease, pet dander, and more. The EPA lists indoor air quality as one of the top 5 health threats in America. Zerorez offers the most advanced, powerful air duct cleaning system available. You can trust in their patent-pending technology to keep you breathing easy and feeling well.

Zerorez is currently offering a cleaning special: $25 per room for the month of February. On rugs and air ducts, you get 25% off. If you’d like to schedule a cleaning or get additional information, visit the Zerorez website for Salt Lake County or Davis County or you can give them a call at (801) 288-9376.

OAKLAND – California Attorney General Rob Bonta, leading a coalition of eight states, the District of Columbia, and New York City, today filed an amicus brief in the Ninth Circuit Court of Appeals in support of the City of Berkeley’s ordinance prohibiting the installation of natural gas hookups in new buildings. Residential and commercial buildings in California are responsible for approximately 25% of all greenhouse gas emissions in the state, and a significant amount of building emissions are attributable to gas-burning appliances, such as furnaces and water heaters, which also emit large amounts of smog-forming oxides of nitrogen (NOx). In today’s brief, the coalition urges the Ninth Circuit to affirm the district court’s decision, which upheld the ordinance against a claim that it is preempted by federal law. 

“Many of us have embraced 21st-century technology in all aspects of our lives except when it comes to heating our homes and workplaces,” said Attorney General Bonta. “The use of gas in buildings is a significant source of emissions and threat to public health and safety. I urge the Ninth Circuit to affirm the district court’s decision and recognize state and local governments’ longstanding authority over gas distribution.”

Since the City of Berkeley passed this first-of-its-kind ordinance, dozens of local governments in California and across the country have adopted similar measures prohibiting the installation of natural gas infrastructure in newly constructed buildings in an effort to fight climate change and protect public health. Gas-burning appliances are significant sources of local emissions. By contrast, the electricity provided by California’s electric grid — increasingly from renewable sources of energy — is better for the climate and local air quality. Shifting away from gas infrastructure and toward electricity also reduces indoor air pollution resulting from gas appliance use, which can exacerbate respiratory conditions like asthma and other health problems. 

In November 2019, the California Restaurant Association sued the City of Berkeley, arguing that its natural gas ordinance is preempted under the Energy Policy and Conservation Act, the federal law authorizing energy efficiency standards for certain consumer appliances. After a district court ruled in the City of Berkeley’s favor, the California Restaurant Association appealed the case to the Ninth Circuit.   

In today’s brief, a California-led coalition argues in support of the City of Berkeley. The coalition argues that the statutory provision that the California Restaurant Association is relying upon preempts only state appliance energy efficiency standards and laws that similarly regulate the amount of energy particular appliances are designed to use. It does not take away state and local governments’ longstanding authority over gas distribution.

Attorney General Bonta is joined by the attorneys general of the District of Columbia, Maryland, Massachusetts, New Jersey, New Mexico, New York, Oregon, and Washington, as well as the City of New York in filing the brief.

It’s Tuesday, February 8, and a California natural gas utility may have to pay up for its efforts to delay climate action.

The United States’ largest natural gas utility is facing the music for its attempts to delay climate action.

California state regulators last week recommended a $9.8 million fine for Southern California Gas Company, or SoCalGas, after finding that the utility violated an order to stop using customers’ dollars to lobby against climate policies. Between June 2018 and January 2021, the company used ratepayers’ funds — without their knowledge — to push back on energy efficiency standards for buildings, argue against electrification requirements, sow doubt about the connection between gas appliances and indoor air pollution, and fund industry advocacy groups.

According to the California Public Utilities Commission, or CPUC, these activities violate requirements that utilities like SoCalGas only use ratepayer funds for projects that benefit customers — energy efficiency improvements, for example, or better safety measures.

SoCalGas has denied wrongdoing and defended its actions by saying they were “in the public’s interest.” It also argued that any penalties for its lobbying activities would violate its right to free speech. But the CPUC disagreed, writing in its decision last week that SoCalGas’ conduct demonstrated “profound, brazen disrespect for the Commission’s authority.”

SoCalGas now has 30 days to appeal the CPUC’s proposed $9.8 million fine — much less than the $124 million fine recommended by a public watchdog office, but a penalty that climate advocates have still called “heartening.”

“We’re happy the commission is finally holding SoCalGas accountable,” said Matt Vespa, a senior attorney for the nonprofit law organization Earthjustice, although he emphasized the need to impose further fines for similar ratepayer-funded activities from before 2018. (Disclosure: Earthjustice is an advertiser with Grist. Advertisers have no role in Grist’s editorial decisions.)

“SoCalGas has been going rogue for so long,” Vespa told me. “They have to be regulated.”

A bad bout of haze in 2015 sparked the desire for two entrepreneurs to find a solution to indoor air pollution. Founders Mr Lester Leong and Mr Benny Jiao both suffered from childhood asthma, and recall their conditions being exacerbated by the annual haze season growing up. Their experiences inspired them to look for ways to improve the air quality indoors.

Together, they founded gush, a local company specialising in sustainable paints and advanced building materials.

“Research shows that traditional building materials and changing climate conditions drastically increase exposure to harmful volatile organic compounds (VOCs) such as aldehydes and benzenes, as well as mould,” the Co-founders explain.

“The long-term accumulation of air pollutants in confined spaces can pose a serious threat to physical and mental health. Research shows that the air indoors can be up to five times more polluted than air outside because of chemicals from cleaning products, aerosols and perfume,” adds Mr Leong, who is the Group Chief Executive Officer of gush.

Their objective was clear: “Since walls form the biggest surface in our densely constructed cities, we thought about innovating the most malleable solution possible: paints.”

Gush consulted professors from local polytechnics, universities and material scientists from the coating industry to develop prototypes. In 2017, after multiple rounds of fine-tuning its formula, gush officially launched its flagship product, ‘Cair’. Thanks to a proprietary catalyst, the paint breaks down VOCs into carbon dioxide and water vapour at the rate of 99 per cent in 21 hours.

In essence, the paint transforms walls into passive air purifiers to keep indoor spaces healthy for occupants. The odourless paint is also anti-mould, anti-bacterial, and has humidity-regulating properties.

Bringing healthy air to homes, offices and hospitals

Their air-purifying paint was a hit with consumers, both in the residential and corporate spaces. Since its launch, Cair paint has been used in more than 1,300 residential and 60 commercial projects in the medical, wellness and hospitality sectors, as well as in office and retail spaces in Singapore and Southeast Asia.
Gush’s clients include Thomson Medical Centre, Farrer Park Hospital, Modern Montessori International, Tanglin Trust School, Grab, and W Hotel.

REME-HALO Indoor Air Purifier

In the war on Covid, wildfire smoke, volatile organic compounds, allergens and other contaminants, the latest HVAC products are using Infrared Light.

In the HVAC world, knowledge is power as well as indoor air purification. It’s more important than ever that today’s consumers understand the choices for improving the air they breathe.”

— Scott H. Park

SILVERDALE, WASHINGTON, UNITED STATES, February 8, 2022 /EINPresswire.com/ — In the war on Covid-19, wildfire smoke, volatile organic compounds, allergens and other airborne pathogens, the latest HVAC technologies are using Infrared light, LEDs and ionization to neutralize these health hazards in the home or workplace as illuminated in downloadable, online user manuals.

A free library of Indoor Air Quality user manuals documents how products like the Reme-Halo, Aerus Air Scrubber and iWave ionizer are able to neutralize the Covid virus with remarkable efficiency. Whole house air purifiers deploying infrared, LED and ionization technologies can purify hazardous air that targets young and old alike.

The process known as Needlepoint Bi-polar Ionization has proven to be effective for contending with indoor air pollution levels that are sometimes 2 to 5 times higher than outdoor levels, and can be 100 times higher in some cases.

Medically, the “NPBI” built into the iWave technology has been effectively used against COVID-19, norovirus, and the flu, removing bacteria, pollen, viruses, and mold, and can be used for pathogen control and particle reduction. As a bonus, it also neutralizes volatile organic compounds, odors, and allergy-causing dander. And it uses your existing home HVAC system as the delivery method.

In laboratory testing, 84.2% of the Covid virus was inactivates in 20 minutes, and at 15 minutes 92.6% of the virus was inactivated. Ions as air scrubbers that are naturally present in the environment around us.

The Reme-Halo Air Purifier is another technology using either infrared or LED light and has been found to be 99.9% effectiveness when tested on COVID-19 at neutralizing the virus.

The ActivePure® technology of the Aerus Air Scrubber was developed for use in space exploration and is in the Space Technology Hall of Fame. Active Purifiers reduce contaminants in the air without needing to first draw the air through their mechanism. Using your HVAC fan, they send ions out into the air and go direct to the contaminants rather than waiting for contaminants to come to them.

For many families with yearly flu concerns, or those who are elderly or immunocompromised, this protection against overall health risk is mow available for installation in the home or workspace.

“In the HVAC world, knowledge is power as well as indoor air purification,” said Scott H. Park who founded Quality Heating and Air on the Olympic Peninsula 28-years ago. “It’s more important than ever that today’s consumers understand the choices for improving the air they breathe. We can affect climate change in our homes, and in the world, if we have the right information at our fingertips.”

Plasmas, which consist of charged particles and are the 4th state of matter, are used in high-tech industrial systems such as in lithography machines to make microchips or in ultrafine particle (UFP) sensors to measure the concentration of tiny particles (smaller than 0.1 micrometers) that could be damaging to human health.

“Due to their small size, UFPs can deposit deep in the lungs and then enter the blood stream, causing irreversible tissue damage and disease,” says Tim Staps, PhD researcher in the Complex Ionized Media group at the department of Applied Physics.

Sensors for society?

While industrial UFP sensors have been around for some time, there are several issues that must be overcome before they are commonplace in society. Their availability would be well-timed too as the Rijksinstituut voor Volksgezondheid en Milieu (RIVM) estimates that the number of deaths in the Netherlands due to the inhalation of particulate matter (including ultrafine particles) emitted by cars and other processes is between 7,000 and 12,000 per year.

The first issue is cost as laboratory-scale devices are priced at 10,000 euros, far too expensive for cars, while the widescale use of the technology is limited by a lack of legislation for ultrafine particles. But many technical issues are also hindering their wide-scale use.

“Besides making compact UFP sensors, they also shouldn’t require continual maintenance. For example, industrial sensors need to be checked every 100 hours, which isn’t feasible for cars,” says Staps. “The sensors also need to be sensitive as UFP concentrations in air can be low and hard to measure.”
