Using three different methods of calculating market potential, results for residential fire sprinkler installations in the United States ranged from $2.9 billion to $3.2 billion annually. Further, four types of labor were analyzed to project the number of additional positions needed as residential fire sprinkler requirements are adopted across the country. "There's no question that the recent passing of residential fire sprinkler requirements to the International Residential Code will change the industry in a breath and timeline never experienced before,"

Japan's domestic shipments of residential air conditioners rose 12 percent in March from a year earlier to 678,736 units, the Japan Refrigeration and Air Conditioning Industry Association said.

A new era for commodities Cheap resources underpinned economic growth for much of the 20th century. The 21st will be different. NOVEMBER 2011 * Richard Dobbs, Jeremy Oppenheim, and Fraser Thompson Source: McKinsey Global Institute, Sustainability & Resource Productivity Practice In This Article Exhibit: In little more than a decade, soaring commodity prices have erased a century of steady declines. About the authors Comments (2) Has the global economy entered an era of persistently high, volatile commodity prices? Our research shows that during the past eight years alone, they have undone the decline of the previous century, rising to levels not seen since the early 1900s (exhibit). In addition, volatility is now greater than at any time since the oil-shocked 1970s because commodity prices increasingly move in lockstep. Our analysis suggests that they will remain high and volatile for at least the next 20 years if current trends hold-barring a major macroeconomic shock-as global resource markets oscillate in response to surging global demand and inelastic supplies. Back to top Demand for energy, food, metals, and water should rise inexorably as three billion new middle-class consumers emerge in the next two decades.1 The global car fleet, for example, is expected almost to double, to 1.7 billion, by 2030. In India, we expect calorie intake per person to rise by 20 percent during that period, while per capita meat consumption in China could increase by 60 percent, to 80 kilograms (176 pounds) a year. Demand for urban infrastructure also will soar. China, for example, could annually add floor space totaling 2.5 times the entire residential and commercial square footage of the city of Chicago, while India could add floor space equal to another Chicago every year. Such dramatic growth in demand for commodities actually isn't unusual. Similar factors were at play throughout the 20th century as the planet's population tripled and demand for various resource

Southwire Co. Inc., a US cablemaker with a focus on building wire production, said that the US residential construction industry has bottomed-out after near-continuous contraction since being heavily impacted by the global economic crisis in late-2008. The company said that it is now necessary to use statistics on housing area under construction in order to analyse and pre-empt demand as government figures on housing starts cause an overestimation of the strength of the recovery in wire and cable demand. This is due to homebuilders more frequently electing to construct smaller homes, requiring less wire and cable than average-sized homes.

"Abstract Most baby-boomers have some familiarity with the classical stigma surrounding aluminum conductors in residential and commercial applications: fire hazard. Mention aluminum wiring in a building or residence and, not surprisingly, a lot of folks will react as if the structure in question should be condemned. How did aluminum get this reputation? Was it deserved? Is it still a valid assumption with today's modern aluminum alloys? Many of the historical stigmas associated with aluminum can be attributed to technical design problems of the older alloys that have now been overcome by higher quality materials and/or addressed by aluminum specific design considerations. This paper addresses the aforementioned issues and investigates the current status of aluminum conductor technology as applied to subsea power cables with a specific emphasis on the following: The Element Aluminum; Early History of Aluminum; Historical Stigmas; Technical Advances; Aluminum (Al) versus Copper (Cu); Aluminum Subsea Cable Experience"

The solar industry and semiconductor industry are intimately connected. Both industries rely on silicon and both use much of the same processing technology and supply chain to produce their products. Nowhere has this connection been on better display than last week at the Moscone Center in San Francisco California, where the Intersolar North America made its debut in conjunction with SEMICON West 2008. The show provided an opportunity for those in the two industries to connect and allowed those companies that work in both spaces to showcase their collective efforts. According to Chris O'Brien, Head of Market Development and Government Relations for North America for Oerlikon Solar, holding the two conferences together gave companies greater exposure and showed the promise of the U.S. solar market. In recent months a number of traditional semiconductor companies including Intel and National Semiconductor have made announcements that they are making plans to enter the solar industry in one way or another. Intel spun off it's solar research area into a new solar company called SpectraWatt. National Semiconductor announced that it will be introducing it's first solar product, SolarMagic, that could raise the efficiency of residential and industrial solar systems. Kevin Kayser, Senior Marketing Manager at National said that he product will be targeted at installers and integrators and much planning went into the company's decision to enter the solar space. "Photovoltaics currently has less than 1% of the energy market, but we think it has potentially one of the fastest growth rates of any alternative energy source. Now certainly we're looking at wind, we're looking geothermal, we're looking at other sources, but from an electronics point of view we saw that we had the most immediate potential impact in solar photovoltaics," Kayser said.

MIT researchers have discovered a way to store solar energy that could make solar power in homes a mainstream energy option and might even make power companies obsolete, at least for residential needs.

A vote could come as early as this week in the U.S. Senate on a bill introduced by Senate Tax Committee Chairman Max Baucus (D-MT) and Senate Majority Leader Harry Reid (D-NV) containing a one-year renewable energy production tax credit (PTC) extension and a small wind turbine investment tax credit. The Senate bill, S. 3335, contains a one-year PTC extension at its current value. After December 31, 2009, any further extension would include the "presumption" of a cost cap, which would, through a complex formula, put a ceiling on the value of the credits of no greater than 35% of project value. The small wind ITC has a cap of US $4,000 per system.The 10-year cost for the PTC, including all technologies to which it applies, is projected to be approximately US $7 billion, while the ITC, which includes solar, would cost approximately US $907 million over 10 years. The bill also includes provisions to extend through 2014 the tax credits for solar energy, fuel cell and microturbine property, as well as the residential energy efficient property tax credit. Marine renewable energies could also benefit from the bill as credits to build wave, tidal, current and ocean thermal energy conversion systems of at least 150 kilowatts (kW) are extended through the end of 2011.

As designed, the cities will have a total of four times the geographic area of Hong Kong, three times the population of Dubai, and - so the Saudis claim - an economic output equal to Singapore's. The coastal King Abdullah Economy City is designed to house two million in an area twice the size of Hong Kong. Entirely funded by domestic and foreign private investors, this is the only one of the four planned cities that is currently under construction. Aside from the seaport and residential area, KAC will also house a sprawling industrial zone, a central business district, a sea resort, and a multi-university education campus.

Long ago, the industry determined that the combination of copper tubing and aluminum fins provided the most efficient transfer of thermal heat in condenser coils. Manufacturers of residential units are not necessarily on that same page - or that line of thinking - today. Most manufacturers, if not all, are revising, have revised, or continue to revise their outdoor coil construction. One of the main objectives, of course, is to increase heat transfer efficiency, as energy efficiency is high on every homeowner's wish list. In the end, each manufacturer believes it has engineered and/or perfected - at least up to now - the most-efficient coil design. Some, like Goodman Manufacturing, have made changes as a direct result of the efficiency offered from R-410A refrigerant.

DOE announced on September 8 that it will award $6.6 million in competitive grants for 15 state-level projects, nine of which focus on developing policy and regulations to support gigawatt-scale clean energy capacity, and six of which focus on developing advanced building codes. Of these awards, $4 million will go to the gigawatt-scale clean energy capacity projects, which will develop policy and regulatory frameworks that will enable gigawatt-scale clean energy, either through renewable energy or demand-side reductions. Although no cost share was mandated, state partners will contribute up to $1.8 million for these projects. The six advanced building codes projects will receive $2.6 million, which will assist states in developing and implementing residential, commercial, or overarching building codes. Along with its financial assistance, DOE will support these projects with ongoing technical assistance.

But today the scenario is different, with builders getting a mix of mid end and affordable housing into their portfolio. Raminder Grover, CEO-Homebay Residential, Jones Lang LaSalle Meghraj, says the revival in sales has been, conservatively speaking, to the tune of around 25% across the mid-to-high income segments, according to his company's sales records. Rohtas Goel, CMD of Delhi-based Omaxe too says there has been a 30% increase in sales thanks to factors such as a reversal in general economic sentiment after the elections and more options available in affordable housing. Statistics too would appear to bear this out. India's largest real estate developer DLF says it has sold almost 1,500 flats in various cities since April, notably some 400 flats in its mainstay market Gurgaon, 700 in Bangalore, 100 plots in Indore, 200 flats in Hyderabad and 50 in Cochin. Rival Unitech has managed to sell more than 4,000 units in the last two and a half months in the National Capital Region, Chennai and Mumbai. Omaxe has also sold almost 500 apartments in its Omaxe Eternity project in Vrindavan.

They want to supply residential and business buildings with largely fiber optic connections because the old copper cabling will soon no longer suffice to access communication networks. The growing Internet data network plus new online and multimedia services require increasing amounts of bandwidth and better transmission technology.

Italian leading manufacturer of copper and copper alloy products KME said that its H1 output dropped 30% to 218,000 tonnes from 313,000 tonnes for the same period a year ago. The company said that there is 'persistent uncertainty and fears that an impulse to industrial activity triggered by a necessity to rebuild stocks will not be sufficient to consolidate recovery.' Demand for copper semis has been badly hit due to the economic downturn as residential construction activities are halted. Demand from industrial production is also adversely affected by a slowdown in investments in new plants and machinery. However, a fall in copper prices earlier in the year helped easing substitution threats from cheaper materials, KME said. The company previously announced that its consolidated sales fell 45% year-on-year to €898.5m (US$1.29b) for the first half of 2009. Net loss was €20.1m, compared to €12.3m of net profit a year ago.

The electricity sector accounts for almost 35 percent of greenhouse gas (GHG) emissions in the United States, and 40 percent of the carbon dioxide (CO2) emissions. Over 80 percent of GHG emissions associated with electricity generation are from the combustion of coal, with nearly all the rest due to natural gas and petroleum combustion. U.S. electricity sales are split among the residential (37 percent), commercial (36 percent), and industrial (27 percent) sectors, where primary uses vary by sector. Over the past 30 years the U.S. electricity sector has become less carbon intensive, and the U.S. economy has grown less electricity-intensive.
