Insulation to Keep Us Warm — Not Warm the Planet

first_imgOK for ozone, bad for climateWith XPS, the blowing agent HFC-134a has a GWP of 1,430, meaning that it’s 1,430 times as potent as carbon dioxide (which is defined as having a GWP of 1). Nearly all closed-cell SPF is made with the blowing agent HFC-245fa, which has a GWP of 1,030. RELATED ARTICLES Relative to global warming, these blowing agents aren’t as bad as the CFCs that were used originally, but they are as bad as the HCFCs (hydrochlorocfluorcarbons) that were adopted as second-generation blowing agents. (Both HFCs and HFOs are considered totally safe for the ozone, which is why CFCs and HCFCs have been phased out.) Insulation: good news, bad newsInsulation materials help our homes save energy and, in so doing, they reduce the combustion of fossil fuels and the release of greenhouse gases.But if the insulation material itself is made with a very-high-GWP blowing agent that may ultimately escape from the insulation, adding a lot of insulation may actually be a bad thing from the standpoint of mitigating climate change. All that was spelled out in my blog post two years ago, “Avoiding the Global Warming Impact of Insulation” and, in greater detail, in the EBN feature article on the same topic. Efficiency boost an added bonusFurther, Solstice HFO will boost the R-value of the insulation material slightly. Compared with HFC-245fa, this HFO produces insulation with 2% higher R-value, and compared with hydrocarbon blowing agents it offers an 8% to 10% improvement, according to Honeywell.While the change is exciting, it is not immediate. The HFO has just received its approvals from the government, and it will take a while to ramp up production and convert refrigerator factories to the new foam. Whirlpool expects to begin incorporating the new blowing agents into its refrigerators in late 2013. Avoiding the Global Warming Impact of InsulationCalculating the Global Warming Impact of Insulation New Blowing Agent Addresses Climate Impact of Foam Insulation Are there closed-cell spray foam products that have low global warming aspects on the market now? Not a great time to invest in productsBoth the SPF and XPS industries have already gone through two major transitions: from CFC to HCFC blowing agents and then from HCFC to HFC blowing agents.With a weak building economy and depressed sales of building materials, enthusiasm for a third major conversion has been limited. But I believe that there will be growing demand to produce products with as little impact on global climate change as possible — and if this year’s heat and drought continue, that demand may well grow.Let’s hope so. Spray-foam manufacturers slower to adopt HFOsBut what about the closed-cell SPF insulation that is commonly used to insulate buildings?SPF manufacturers will probably be replacing the HFC-245fa with HFO … but it’s unclear exactly when that will happen. Rick Duncan, the technical director at the Spray Polyurethane Foam Alliance (SPFA), the trade association serving the SPF industry, told me that some SPF manufacturers (“system houses”) are conducting field trials with the new HFO blowing agents, but not all of them. (At least one manufacturer, Icynene, also makes a water-blown, medium-density foam, MD-R-200, which insulates to R-5.2 per inch and is referred to as both an open-cell and closed-cell product on the Icynene website; most other water-blown SPF products are believed to have been discontinued.)Unlike in 2003 when federal regulations mandated a switch from HCFC to HFC blowing agents due to ozone depletion concerns, there are no similar regulations requiring a switch from HFCs to HFOs.center_img It’s up to usAnd the conversion takes time and is expensive — about one year and at least $100,000, says Duncan. With the building industry still in an economic slump, producers aren’t looking to spend a lot of additional money on product development.Duncan believes, however, that when a new life-cycle assessment (LCA) report on SPF comes out that SPFA is now finalizing, customers will begin asking for lower-GWP foam and manufacturers will respond by producing it. From an environmental standpoint, open-cell SPF (which doesn’t include HFC blowing agents) has just 1/20th the global warming impact of closed-cell SPF. I’ve been pretty vocal about a big problem with some of our most common insulation materials: that they are made using blowing agents that are highly potent greenhouse gases.All extruded polystyrene (XPS) and most closed-cell spray polyurethane foams (SPF) are made with HFC (hydrofluorocarbon) blowing agents that have global warming potentials (GWPs) many hundreds of times greater than that of carbon dioxide.

Blowing agents: the next generationAnyway, given all this, I’ve been closely following the developments by industry in coming up with alternatives that are neither ozone depleters nor significant greenhouse gases.Two years ago, it appeared that the leading candidates were HFOs (hydrofluoroolefins), and Honeywell announced the development of such a product in 2011. And indeed, it was just announced last week that Whirlpool, the nation’s largest appliance manufacturer (with such brands as Maytag, Amana, Jenn-Air, and KitchenAid, along with Whirlpool), was switching to a new HFO blowing agent for the polyurethane insulation in all of its refrigerators.Whirlpool will be using the new Solstice Liquid Blowing Agent made by Honeywell, one of the nation’s three producers of blowing agents (along with DuPont and Arkema). Solstice HFO has zero ozone depletion potential and a GWP of just 4.7 to 7.0—similar to that of the various hydrocarbon blowing agents used in expanded polystyrene and polyisocyanurate — and insignificant relative to global warming. Less action in the XPS campI was not able to get as much information from the extruded polystyrene industry about when the HFC-134a might be replaced with a lower-GWP blowing agent and whether there is a gaseous form of HFO that could work for that industry. (While a liquid blowing agent is used in producing SPF, a gaseous blowing agent is required for XPS.)Jan McKinnon, the senior communications manager at Dow Building Solutions (manufacturer of Dow Styrofoam XPS), says that the company is looking for ways to reduce its greenhouse gas emissions. “Since the launch of our new formulation in 2010 [converting from HCFC-142b to HFC-134a], we continue to look at lowering our blowing agent global warming potential, and we have an active process in place to reduce it by 15%,” she told me. She said that they are actively evaluating alternative blowing agents for XPS, “but most of these technologies are still in their infancy.”last_img read more

Police, students clash in Kolkata; many hurt

first_imgA clash erupted on Friday between the police and members of Left-affiliated students’ organisations who were marching to the State Secretariat. The protesters had organised a march to the State Secretariat to protest against rampant unemployment. The activists had collected lakhs of job applications from across the State and wanted to give it to Chief Minister Mamata Banerjee. Violence started a few kilometres from the Nabanna building when police personnel lobbed tear gas shells, resorted to baton charge, and used water cannons to disperse the crowd. Witnesses reported seeing several injured and bleeding protesters. “Some of our students were seriously injured. They were protesting for the right to work and stood against disproportionate display of brute force by the police. I salute them,” Communist Party of India (Marxist) leader and Polit Bureau member Mohd. Salim said.He also ridiculed the Didi ke Bolo campaign launched by the Trinamool Congress where people can call up the Chief Minister with their grievances. The CPI(M) leader said that when students want to meet and give deputation to the CM they are met with brute force.The CPI(M) claimed that over 60 supporters were injured and some had to be hospitalised. The police said that five of their personnel suffered injuries.Earlier this week, violence had erupted when BJP supporters marched to the Calcutta Electric Supply Corporation HQ in Esplanade demanding a reduction in power tariff.last_img read more

The Spanish driver has completed only three races so far.The Spa track, nestled in the Ardennes forest, is the longest in F1 at 7 kilometers (4.3 miles) and the race is often full of incident, especially when it rains.It stayed dry, but there was one heated clash between Force India drivers Sergio Perez and Esteban Ocon, prompting the safety car to come out after they made contact with each other on lap 30, sending debris onto the track.Their tense relationship is degrading fast.After bumping on the track at the Azerbaijan GP in June, they did it again when they touched wheels as Ocon moved on the outside of the track shortly after the start, with Perez responding by squeezing the Frenchman against the barrier.Later the pair came into contact again with Ocon’s front wing flying away and a tire dropping off Perez’s car as a result.This prompted a furious, expletive-laced outburst from Ocon, who was already unhappy that his team had pitted Perez for new tires ahead of him. After both cars pitted for repairs, Ocon finished ninth but Perez had to retire just before the end.The safety car stayed out for four laps, which was too long for Hamilton’s liking, and he used an expletive of his own to complain.“There was hardly any debris about,” Hamilton said afterward. “They did a good job cleaning the track.” Don’t miss out on the latest news and information.

His exasperation was understandable — it is the sixth time this season he has failed to finish the race, and some 80,000 Dutch fans had crossed the border to cheer him on.“I’m not happy at all,” Verstappen said. “I am very disappointed for the fans who buy an expensive ticket to watch and I retire after eight laps.
