Improved inverter for photovoltaic systemsBuildingGreen calls the Sunny Boy inverters from SMA America “revolutionary” because they can provide power from grid-tied photovoltaic systems during a power outage. That’s not the case with conventional inverters; most grid-tied PV arrays can’t power so much as a single light bulb when utility power isn’t available.Alex Wilson wrote a GBA blog about the new Sunny Boy inverter in August 2013.The Sunny Boy inverters can switch from interactive operation to providing power to a dedicated outlet, delivering 1500 watts of electricity. That’s not enough to run a big appliance, BuildingGreen said, but it would be enough to charge a cell phone or laptop computer, and that might be just enough to make a difference in an emergency. Mineral wool board insulationRoxul’s ComfortBoard, a semi-rigid mineral wool board insulation, made the list on the strength of its high pre-consumer recycled content and low toxicity. It’s intended for residential and commercial use over exterior sheathing. RELATED ARTICLES Nov. 2012: BuildingGreen Announces Top 10 Green Building Products Oct. 2011: Top 10 Green Building Products Nov. 2009: Top 10 Green Building Products BuildingGreen has posted its choices for the most innovative green products of the last 12 months, a list that includes products for both commercial and residential construction.“The products we’re recognizing this year are remarkable in their diversity and innovation,” said Alex Wilson, founder of BuildingGreen, in a press release announcing the choices. “We are thrilled to call attention to these products, which are helping to create more sustainable, greener buildings throughout North America.”The winners will be presented at the U.S. Green Building Council’s Greenbuild convention Nov. 21 in Philadelphia. The award winners are picked by BuildingGreen editors from the hundreds of products reviewed in the past year.This year’s list includes a mix of product types, from dimensional stone manufactured from waste to a retrofit faÃ§ade system for commercial buildings that incorporates high-performance windows, insulation and cladding.Here’s a sampling of this year’s Top Ten products. Alex Wilson wrote a GBA blog about ComfortBoard in May 2013.ComfortBoard comes in two densities — 8 lb. per cubic foot (pcf) in the residential version and 11 pcf in the commercial product. BuildingGreen said its density makes it rigid enough to be used on the outside of a building as an affordable alternative to foam plastic insulation. BuildingGreen editors also liked ComfortBoard for its sound-absorption qualities and fire resistance without the use of flame retardants. Even when damp, it’s still a good insulator (R-4 to 4.2 per inch), so it can be used behind a rainscreen assembly on exterior walls.The primary material used in ComfortBoard is iron ore slag. It’s produced with a urea-extended phenol formaldehyde binder, but BuildingGreen said heat processing drives off most of the formaldehyde during production, “resulting in extremely low emissions.” A better light bulbSoraa’s Vivid MR-16 is a light-emitting diode (LED) assembly that produces a “full spectrum” light rivaling that of halogens. According to the manufacturer, the bulbs reach a 65-watt halogen equivalent output with 75% less energy. They also operate at much lower temperatures, and LEDs last much longer than other types of light bulbs.The color rendering index, a measure of how accurately light shows colors, is as high as 95 on a 100-point scale, and the lamps are available in three beam angles: 14, 25, and 36 degrees.Vivid LEDs are manufactured somewhat differently from other LEDs on the market to produce a full spectrum of light. Lamps cost $32.
A frustrated Lionel Messi said a joke goal had complicated Argentina’s Copa America start as the hosts struggled to impose themselves in their 1-1 draw with Bolivia in the tournament’s first match on Friday.

We did some things well but we have to keep improving,” Messi told reporters.Bolivia’s point in the match in La Plata was the first they have ever picked up in a competitive match on Argentine soil.It also denied Argentina revenge for a 6- 1 roasting under former coach Diego Maradona in a World Cup qualifier at high altitude in La Paz two years ago. ‘A night without altitude’ was the headline in the daily Clarin in a play on words on the expression in Spanish which would better translate as a night without class.Argentina played into the hands of a modest but well- organised Bolivia, failing to execute coach Sergio Batista’s passing game modelled on Messi’s club side Barcelona. “It’s very difficult to play like Barcelona, but the idea is ball possession,” Batista told reporters.”We tried to play and be a team with a lot of the ball, but Bolivia put a lot of people in the middle and clogged the spaces. It was a difficult debut.” Batista said on the eve of the match he had not recalled forward Carlos Tevez just because of popular demand. He explained that with the player of the people in his side he would get more football and less vertigo, meaning less headless running at the opposition defence.advertisementYet Tevez and Ezequiel Lavezzi, the two players flanking Messi in attack, did just that with the former earning some of the lowest match ratings in Saturday’s papers. Messi received an ovation from the crowd, but not for the reasons he would have liked, when he stood up to Bolivia’s captain Ronald Raldes after a clash.Colombia winStriker Adrian Ramos earned Colombia a 1-0 win over 10- man Costa Rica that put them top of Group-A after their first match at the Copa America on Saturday.Ramos beat the offside trap to run onto a through pass from winger Fredy Guarin, round goalkeeper Leonel Moreira and put the Colombians ahead seconds before half-time.Costa Rica had been reduced to 10 men after 27 minutes when forward Randall Brenes was shown a straight red card after a dangerous tackle on defender Luis Perea.Meanwhile, Brazil play Venezuela in their opener on Sunday and will be approaching the game with caution, after Argentina’s result.- With inputs from agencies
