GI Energy is pleased to announce that the innovative Ground Source Heat Pump (GSHP) system they have engineered and built for The Emma and Georgina Bloomberg Center at Cornell Tech, Cornell University’s new applied tech campus on NYC’s Roosevelt Island, is now fully operational.
Highly efficient and cost-effective to run, the GSHP system delivers all the heating, cooling, and domestic hot water for The Bloomberg Center without any direct combustion of fossil fuels. The combination of the facility’s low energy design, solar photovoltaic panels and GI Energy’s GSHP system is expected to save up to 500 tons of carbon dioxide per year.
Eighty boreholes have been drilled to a depth of 400 feet, intercepting water-filled fissures in the local bedrock. The system then takes advantage of this water to increase its efficiency. It is the first time in the USA a supplemental groundwater pumping system has been applied to a closed-loop geothermal system in this way. It is designed to support The Bloomberg Center’s aspiration for radically lower energy use and minimal environmental impact.
Steve Beyers, Energy Engineer at Cornell University, notes “The Bloomberg Center’s innovative Ground Source Heat Pump system is a perfect match for Cornell’s mission of education, research, and outreach. It demonstrates respect for the environment while saving energy dollars for investment into our education mission, but it’s also a great experiment in new technology. It’s a win-win for the University.”
GI Energy’s CEO, Tom Chadwick added “this project provides a blueprint for achieving NYC’s ambitious geothermal energy plans, as set out by Mayor di Blasio. Cornell Tech and NYC are both iconic and visionary – the geothermal system we have created is in keeping with this”.

Cornell Tech brings together faculty, business leaders, tech entrepreneurs and students in a catalytic environment to produce visionary results grounded in significant needs that will reinvent the way we live in the digital age. The Jacobs Technion-Cornell Institute embodies the academic partnership between the Technion-Israel Institute of Technology and Cornell University on the Cornell Tech campus.
From 2012-2017, the campus was temporarily located in Google’s New York City building. In fall 2017, 30 world-class faculty and about 300 graduate students moved to the first phase of Cornell Tech’s permanent campus on Roosevelt Island, continuing to conduct groundbreaking research, collaborate extensively with tech-oriented companies and organizations and pursue their own startups. When fully completed, the campus will include two million square feet of state-of-the-art buildings, over two acres of open space, and will be home to more than 2,000 graduate students and hundreds of faculty and staff.
Residents living in newly built homes in Parkland are complaining of mold, and at least two big builders have taken steps to fix the problem.
Sowande Johnson, director of development services for Parkland, said WCI Communities Inc. and Standard Pacific of Florida have been approved for permits to complete work that they hope will eliminate the fungus.
A third builder, Toll Brothers, has said it also plans to apply for a permit, Johnson said.
Those companies, along with Lennar Homes, are building hundreds of high-end homes in Parkland, the last available area for large-scale residential construction in Broward County. Johnson said he hasn’t heard of any problems with the Lennar properties.
Johnson said the city has received a few complaints, and he doesn’t have “even the slightest idea” how many homes may be affected.
WCI’s permit application outlines plans to install a dehumidifier, while Standard Pacific is using spray foam insulation. Johnson said it may take a few months to determine whether the proposed fixes will work.
“We’ll have to wait until things heat up [in the summer] to find out if it’s a true solution,” Johnson said. “If not, they’ll have to come back with another solution to remedy the problem.”
Jon Rapaport, division president for WCI, said the Bonita Springs-based builder received a “couple of dozen complaints” but not all of those homeowners had mold.
Still, out of an abundance of caution, WCI made modifications in more than 100 Heron Bay homes at no charge to the owners, he said.
Rapaport attributed the mold to a design issue. WCI sealed openings and made changes to ventilation that lets moisture leave attics. In addition, WCI is offering the dehumidifiers to homeowners, he said.
“We wanted to do the right thing,” Rapaport said. “Now we seem to not have a problem at all.”
WCI, expected to soon merge with Lennar as part of a $643 million deal, has built the vast majority of the nearly 3,000 homes in Heron Bay over the past two decades. The master-planned development, off the Sawgrass Expressway at Coral Ridge Drive, is one of the largest in the region.
Standard Pacific, which builds in the Watercrest at Parkland community, did not respond to requests for comment. In 2015, the company combined with Ryland Homes to form CalAtlantic Group of Irvine, Calif.
Horsham, Pa.-based Toll Brothers builds in the Parkland Golf & Country Club. A publicist for Toll said officials were not available to comment, but she released a statement from the company.
“Toll Brothers stands behind its homes with a comprehensive warranty and we work with our homeowners and provide them with information on operating their home systems efficiently and within their design criteria,” the statement said.
In 2015, Angela Mesa-Taylor moved into a rented home in Heron Bay’s Osprey Lake subdivison. Soon after, she noticed that she and her children were constantly sick, but she just thought it was her young twins bringing home coughs and colds from their play dates.
Then her housekeeper pointed to mold on the ceiling in the master bathroom. Another bathroom had the same problem, she said.
Mesa-Taylor said the builder, WCI, tried to address her concerns, but the mold persisted. Meanwhile, she said she heard similar complaints from neighbors.
Within days of discovering the mold, Mesa-Taylor said she moved her children out of the home and continued to press WCI for answers. Not satisfied with the results, she filed suit last summer in Broward County Circuit Court. The complaint was amended in November.
“Every fix was not a fix,” said Mesa-Taylor, 38. “It seemed to be very, very temporary and superficial.”
The suit, which seeks damages in excess of $15,000, alleges that the mold was caused by design and construction defects and led to chronic health problems.
An attorney for the builder declined to discuss the case. Rapaport, the WCI division president, said he can’t comment on pending litigation.
Scott Gelfand, Mesa-Taylor’s Coral Springs lawyer, said he has spoken to more than 100 owners complaining of mold in Heron Bay homes built within the last several years. Some may be reluctant to discuss the problem publicly because they’re worried about property values, but homes that are properly remediated tend to sell for full market value, he said.
Johnson, the development services director for Parkland, said he suspects mold is occurring in other homes across Florida. But Truly Burton, executive vice president of the Builders Association of South Florida, said she isn’t aware of an ongoing problem statewide.
David Cobb, a former homebuilder and now a regional director for the Metrostudy research firm, agrees that mold is common in a humid climate and often is the result of workmanship issues.
But Cobb also cited another cause: improper home maintenance. He said homeowners should inspect homes annually, caulking around windows and doors and painting every few years to keep mold at bay.
“People who buy new homes say, ‘It’s new, so I don’t have to do anything to it,’ and that is totally incorrect,” Cobb said.
SB 1073, the California Lead Safety Enhancement Act of 2016
California Lead Safety Enhancement Act of 2016 was recently introduced by Senate Majority Leader Bill Monning (17th Dist). The bill eliminates regulatory confusion regarding certification for lead paint removal by aligning California law with the United States Environmental Protection Agency’s Renovation Repair and Painting rule.
As you know, California’s lead laws and the federal RRP complement each other in many ways, but there are differences that make implementing two sets of regulations difficult and confusing. In addition, there is little enforcement, so that firms who don’t play by the rules have an unfair advantage over those who do.
SB 1073 will help fix these problems.
The bill (one of the sponsors is the California Association of Code Enforcement Officers) does not create any new regulations or fees. Instead, it conforms federal and state regulations to minimize regulatory confusion and encourages state, county and city enforcement while using existing fees to cover costs associated with increased state responsibilities.
Call to Action!
Last week, SB 1073 passed out of the Senate Committee on Environmental Quality. As it moves forward, it will face many challenges, so expanding the list of supporters is vitally important.
RRP Certified Individuals: For those of you who complain about the lack of enforcement and the difficulty following both California and RRP regulations, now is your chance to set things right. A few minutes of your time to add your name to the list of supporters will make a huge difference.
CDPH Certified Individuals Enforcement of lead safe work practices will benefit both abatement and testing companies, so please add your company to the list of supporters.
Don’t wait, take a few minutes today to express your support for SB 1073, the California Lead Safety Enhancement Act of 2016.
Lumber Liquidators violated California’s air-quality controls by importing wood with formaldehyde
Beleaguered flooring retailer Lumber Liquidators is paying $2.5 million to settle allegations that some of its products violated California’s air-safety standards.
The penalty announced Tuesday was the latest that Lumber Liquidators has absorbed for formerly selling laminate flooring made in China.
In this case, Lumber Liquidators faced allegations that the imported flooring contained high levels of the carcinogen formaldehyde that violated California’s air-quality controls. The flooring was sold at Lumber Liquidators’ California stores from September 2013 until May 2015 when the retailer suspended sales of the products made in China.
Lumber Liquidators currently operates 40 of its 375 stores in California.
The Toano, Virginia, company didn’t acknowledge any wrongdoing in the settlement with the California Air Resources Board.
Last year, Lumber Liquidators paid $13.2 million in fines and pleaded guilty to environmental crimes for importing China-made flooring that contained timber illegally logged in eastern Russia.
Lumber Liquidators still faces a variety of class-action lawsuits revolving around the formaldehyde levels of the China-made flooring.

The legal fallout so far has been less costly to Lumber Liquidators than the damage done to its stock since investigation shown slightly more than a year ago “60 Minutes” raised questions about whether the retailer was selling potentially hazardous flooring.
Shares of Lumber Liquidators Holdings Inc. have plunged more than 70 percent since the TV program aired, a downturn that has wiped out more than $1 billion in stockholder wealth. The shares rallied Tuesday, gaining $1.74 to $13.76 in afternoon trading.
What is formaldehyde?
Formaldehyde is a colorless, flammable, strong-smelling chemical that is used in building materials and to produce many household products. It is used in pressed-wood products, such as particleboard, plywood, and fiberboard; glues and adhesives; permanent-press fabrics; paper product coatings; and certain insulation materials. In addition, formaldehyde is commonly used as an industrial fungicide, germicide, and disinfectant, and as a preservative in mortuaries and medical laboratories. Formaldehyde also occurs naturally in the environment. It is produced in small amounts by most living organisms as part of normal metabolic processes.
How is the general population exposed to formaldehyde?
According to a 1997 report by the U.S. Consumer Product Safety Commission, formaldehyde is normally present in both indoor and outdoor air at low levels, usually less than 0.03 parts of formaldehyde per million parts of air (ppm). Materials containing formaldehyde can release formaldehyde gas or vapor into the air. One source of formaldehyde exposure in the air is automobile tailpipe emissions.
During the 1970s, urea-formaldehyde foam insulation (UFFI) was used in many homes. However, few homes are now insulated with UFFI. Homes in which UFFI was installed many years ago are not likely to have high formaldehyde levels now. Pressed-wood products containing formaldehyde resins are often a significant source of formaldehyde in homes. Other potential indoor sources of formaldehyde include cigarette smoke and the use of unvented fuel-burning appliances, such as gas stoves, wood-burning stoves, and kerosene heaters.
Industrial workers who produce formaldehyde or formaldehyde-containing products, laboratory technicians, certain health care professionals, and mortuary employees may be exposed to higher levels of formaldehyde than the general public. Exposure occurs primarily by inhaling formaldehyde gas or vapor from the air or by absorbing liquids containing formaldehyde through the skin.
Since the well began leaking Oct. 23, thousands of people in the Porter Ranch area say they have suffered headaches, nosebleeds, nausea and other symptoms from the escaping gas. The smell comes from an additive called mercaptan that is used to warn people of leaking natural gas, which is ordinarily odorless.
Southern California Gas Co. is paying to relocate those who say they are being sickened.
On Oct. 23, gas company employees noticed a leak out of the ground near a well called SS-25. It was late afternoon, so they decided to come back in the morning to fix it.
The next day, however, their efforts were unsuccessful. Gas was now billowing downhill into Porter Ranch, an upscale community on the northern edge of the San Fernando Valley. Customers were beginning to complain about the smell.
Gas leaks are not uncommon, and it took a couple weeks for this one to become news. When Anderle heard about it, in early November, she pulled up the well record on a state website. The file dates back to when the well was drilled in 1953. As she looked it over, she zeroed in on a piece of equipment 8,451 feet underground called a sub-surface safety valve.
If it were working properly, the gas company would be able to shut down the well. The fact that SoCalGas hadn’t meant, to her, that it must be broken. The records indicated that it had not been inspected since 1976.
SS-25 was cemented only from the bottom up to a depth of 6,600 feet. The rest — more than a mile of steel pipe — was left exposed to the rock formation. At the top, the 7-inch casing is surrounded by an 11¾-inch surface casing, which is cemented to the rock. But a new well also would have a layer of cement between those casings to provide greater strength and protection from corrosion.
Gas is now leaking through a hole in the 7-inch casing at 470 feet down to the bottom of the outer casing at 990 feet, and out through the rock to the surface.
The corporate culture of SoCalGas is nothing if not deliberate. And so, in 2014, the company proposed a methodical effort to check each well for corrosion. It would take about seven years and cost tens of millions of dollars. The plan was part of a request to the Public Utilities Commission to increase customers’ monthly gas bills by 5.5 percent. The alternative was to fix leaks only as they occurred, which one executive warned could be dangerous and lead to “major situational or media incidents.”
The SoCalGas plan went well beyond the requirements imposed by the state Division of Oil, Gas and Geothermic Resources, or DOGGR. Steve Bohlen, the outgoing head of DOGGR, has said several times that it does not appear that Southern California Gas violated any regulations.
Gas has now been spewing out of the ground at Aliso Canyon for two months. The gas company expects it to continue for up to another three months. Methane is a potent contributor to climate change. By one estimate, the leak is producing greenhouse gas emissions equivalent to the tailpipes of 2.3 million cars.
The Aliso Canyon leak has increased the state’s methane emissions by 21 percent. As of now, 2.3 percent of the state’s entire carbon footprint is coming from one hole in the ground above Porter Ranch.
“This is an environmental disaster,” said Mayor Eric Garcetti, who stopped by Porter Ranch Community School in November, just before flying to Paris for the United Nations climate change conference. “It’s devastating. It makes you question the long-term sustainability of a carbon-based power system.”
The local impact also has been severe. About 30,000 people live in Porter Ranch, a bedroom community of gated developments with 4,000-square-foot homes that sell for $1 million or more. The neighborhood offers good schools, clean air and a sense of security. All of that has been disrupted. Many residents have experienced headaches, nosebleeds, nausea or other symptoms. Some 2,000 families have been moved to hotels or short-term rentals to escape the gas.
is also known as methanethiol and is a harmless but pungent-smelling gas which has been described as having the stench of rotting cabbages or smelly socks.
It is often added to natural gas, which is colourless and odourless, to make it easier to detect.
The gas is an organic substance, made of carbon, hydrogen and sulphur, and is found naturally in living organisms, including the human body where it is a waste product of normal metabolism. It is one of the chemicals responsible for the foul smell of bad breath and flatulence.
People who have eaten asparagus can experience the distinctive smell of mercaptan in their urine within 30 minutes of consuming the vegetable, which contains substances that are quickly broken down to methanethiol. However, not everyone is able to smell mercaptan in their urine as a genetic mutation in some people means they are immune to the odour.
The great advantage of mercaptan for industrial purposes is that it can be detected by most people in extremely small quantities, less than one part per million. This makes it an ideal additive to odourless gases, and, like natural gas, it is flammable.
What benzene is
Benzene is a chemical that is a colorless or light yellow liquid at room temperature. It has a sweet odor and is highly flammable.
Benzene evaporates into the air very quickly. Its vapor is heavier than air and may sink into low-lying areas.
Benzene dissolves only slightly in water and will float on top of water.
Where benzene is found and how it is used
Benzene is formed from both natural processes and human activities.
Natural sources of benzene include volcanoes and forest fires. Benzene is also a natural part of crude oil, gasoline, and cigarette smoke.
Benzene is widely used in the United States. It ranks in the top 20 chemicals for production volume.
Some industries use benzene to make other chemicals that are used to make plastics, resins, and nylon and synthetic fibers. Benzene is also used to make some types of lubricants, rubbers, dyes, detergents, drugs, and pesticides.
How you could be exposed to benzene
Outdoor air contains low levels of benzene from tobacco smoke, gas stations, motor vehicle exhaust, and industrial emissions.
Indoor air generally contains levels of benzene higher than those in outdoor air. The benzene in indoor air comes from products that contain benzene such as glues, paints, furniture wax, and detergents.
The air around hazardous waste sites or gas stations can contain higher levels of benzene than in other areas.
Benzene leaks from underground storage tanks or from hazardous waste sites containing benzene can contaminate well water.
People working in industries that make or use benzene may be exposed to the highest levels of it.
A major source of benzene exposure is tobacco smoke.
Norovirus (bacteria) has sickened 80 Boston College students who ate at a nearby Chipotle restaurant, state health officials said Tuesday.
“Initial testing conducted by the State Public Health has shown the presence of norovirus,” the health department said in a statement.
Although many of the students said they feared they’d been struck with the same E. coli bacteria that made 52 people in nine states sick this fall after eating at Chipotle restaurants, experts said the pattern of illness didn’t look like E. coli.
“Health officials in Boston believe this is likely a norovirus, which seems consistent with the pattern, in our estimation,” Chipotle spokesman Chris Arnold told NBC News.
Norovirus, sometimes known as the winter vomiting bug in the UK, is the most common cause of viral gastroenteritis in humans. It affects people of all ages. The virus is transmitted by fecally contaminated food or water, by person-to-person contact, and via aerosolization of the virus and subsequent contamination of surfaces. The virus affects around 267 million people and causes over 200,000 deaths each year; these deaths are usually in less developed countries and in the very young, elderly and immunosuppressed.
You can get dehydrated if you are not able to drink enough liquids. You may urinate less, have a dry mouth and throat, and feel dizzy.
30 Boston College students sick after eating at Chipotle.
City health officials ordered the outlet closed after an inspection showed the cooked chicken used to make burritos, tacos and other dishes was being kept at too low a temperature, an employee worked while showing signs of illness and because of the reports of possible foodborne illness.
Chipotle said it had voluntarily closed the restaurant in the Brighton section of the city.
“All 80 students have confirmed that they ate at the Chipotle Restaurant in Cleveland Circle during the weekend,” Boston College said in a statement.
Norovirus is notorious for causing large outbreaks of sickness and it can be spread by a single sick restaurant worker or one sick patron. Simple handwashing is often not enough to prevent its spread.
The Centers for Disease Control and Prevention says it’s still not sure what particular food caused the E. coli outbreak at Chipotle. A separate E. coli outbreak that’s made 19 people sick in seven states was linked to celery sold at Costco, 7-11, King Sooper and other stores.
Symptoms of both illnesses are similar — diarrhea, stomach cramps and fever. But norovirus is far more likely than E. coli to cause vomiting.
The most common symptoms are:
Other symptoms include:
Practice proper hand hygiene
Wash your hands carefully with soap and water—
especially after using the toilet and changing diapers, and
always before eating, preparing, or handling food.
Noroviruses can be found in your vomit or stool even before you start feeling sick. The virus can stay in your stool for 2 weeks or more after you feel better. So, it is important to continue washing your hands often during this time.
Alcohol-based hand sanitizers can be used in addition to hand washing. But, they should not be used as a substitute for washing with soap and water. See “Handwashing: Clean Hands Save Lives.”
Wash fruits and vegetables and cook seafood thoroughly
Carefully wash fruits and vegetables before preparing and eating them. Cook oysters and other shellfish thoroughly before eating them.
Be aware that noroviruses are relatively resistant. They can survive temperatures as high as 140°F and quick steaming processes that are often used for cooking shellfish.
Food that might be contaminated with norovirus should be thrown out.
Keep sick infants and children out of areas where food is being handled and prepared.
When you are sick, do not prepare food or care for others who are sick
You should not prepare food for others or provide healthcare while you are sick and for at least 2 days after symptoms stop. This also applies to sick workers in settings such as schools and daycares where they may expose people to norovirus.
Many local and state health departments require that food workers and preparers with norovirus illness not work until at least 48 hours after symptoms stop. If you were recently sick, you can be given different duties in the restaurant, such as working at a cash register or hosting.
Note: Evidence for efficacy of a cleaning agent against norovirus is usually based on studies using feline calicivirus (FCV)—a virus related to norovirus—as a surrogate. However, FCV and norovirus exhibit different physiochemical properties; thus, it is unclear whether inactivation of FCV by a specific cleaning agent reflects efficacy of such solutions against norovirus.
Wash laundry thoroughly
Immediately remove and wash clothes or linens that may be contaminated with vomit or stool (feces).
handle soiled items carefully without agitating them,
wear rubber or disposable gloves while handling soiled items and wash your hands after, and
wash the items with detergent at the maximum available cycle length then machine dry them.
