Creating power by the Yard

first_imgSustainability often happens behind the scenes. But Harvard’s newest renewable energy project is also among its most conspicuous: more than 3,200 square feet of solar panels installed over the summer atop the three buildings that make up Canaday Hall, a freshman dormitory on the northern periphery of Harvard Yard.The panels are part of a solar thermal and steam tunnel heat-recovery project that’s expected to supply at least 60 percent of domestic hot water for all buildings in the Yard.  By using thermal energy to heat water instead of using fossil fuels, the Faculty of Arts and Sciences (FAS) will take another step toward meeting the University’s goal of cutting greenhouse gas emissions 30 percent below a 2006 baseline by 2016, including new growth.The solar panels were installed without needing to modify Canaday’s roofs, which were already angled toward the south at about 35 degrees. The existing roof proved to be an optimal environment for capturing solar energy, said Jay Phillips, senior director of operations for FAS.“This was an ideal project for many reasons,” Phillips said. “The prominent location made it especially attractive because we could take advantage of the opportunity to educate the Harvard community about the benefits of clean, renewable energy for our campus.”For more than 15 years, five large natural gas-fired boilers beneath Canaday have provided hot water to the buildings in the Yard, feeding a loop that runs beneath the historic grounds.  A network of glycol-filled pipes now connects the rooftop solar panels to the new hybrid heating system, using the sun’s power to heat water for showers, hand washing, and dishwasher.“It’s nice to know that when I use hot water, it isn’t at the expense of the environment,” said Canaday resident Jody Heck. “I love knowing that my hot water comes from solar panels on my dorm. It is a great idea.”Glycol was used, in part, because it will not freeze during a harsh New England winter. A solar thermal system like the one installed on Canaday’s roofs is 55.4 percent efficient, compared with just 20 to 30 percent for a conventional fossil fuel system.The hybrid system also collects exhaust heat from a steam tunnel under Canaday.  A new fan in the tunnel draws hot air up to a vent on the Yard.  The fan includes a set of eight coils that capture the heat at temperatures of up to 105 degrees, running it through additional glycol loops that feed into a common buffer tank in the basement of Canaday, where the heat is combined with that from the solar array.This 1,000-gallon buffer tank, which replaces the need for gas-fired boilers, pre-heats city of Cambridge water to 130 degrees before it is pumped to buildings around the Yard.  During early September’s heat wave, Phillips says, 100 percent of the Yard’s hot water needs were met through the new hybrid system during daytime.On average, about 40 percent of the thermal energy provided by the new system will come from the solar panels, with the remaining 60 percent supplied by the steam tunnel heat recovery.  The older, gas-fired boilers will remain as a back-up heating source, especially during cloudy days when the solar panels are not able to collect sufficient thermal energy.The project will prevent an estimated 166 metric tons of CO2, a key greenhouse gas, from being released into the atmosphere annually.  It is expected to pay for itself within 10 years.A monitoring system will allow Canaday residents and the Harvard community to assess the system’s productivity, displaying readings on public kiosks and web-based graphs that can also be easily exported for analysis.Across the University, facility managers are integrating renewable energy and green building standards into construction projects as part of the sustainability commitment.  Energy audits and cost-effective energy efficiency projects are also helping existing buildings to cut energy and achieve savings.  Additional solar thermal projects on campus include the University Operations Services headquarters at 46 Blackstone St., the FAS co-ed dorm at 3 Sacramento St., and two Harvard Real Estate Services (HRES) properties on Broadway and Prescott Street.last_img read more

USC prepares for the season’s home stretch

first_imgAfter narrowly dropping its fourth game of the year to No. 1 UCLA last Sunday, the No. 3 USC men’s water polo team will try to kickstart a late hot streak against No. 4 Long Beach State on Saturday and No. 12 UC Irvine on Sunday and try to channel the magic of last year’s NCAA Championship team.Italian stallion · Freshman driver Matteo Morelli, who hails from Naples, Italy, ranks third on the team with 32 goals so far this season, including an impressive five-goal performance against Chapman in September. – Brian Ji | Daily Trojan“If we can go 3-0 in the next three games, we’re going to have the same record as last year’s team had going into the conference tournament,” USC head coach Jovan Vavic said. “Considering that we have nine freshmen playing, I don’t think that’s bad. I think how we respond in those three games is going to tell a lot about what kind of a team we have, and I, at this point, still strongly believe we have the best team in the nation.”Last year, the Trojans went 28-4 and swept the Mountain Pacific Sports Federation tournament en route to winning their sixth straight national title. After the Bruins dealt the Trojans their second loss in the 2014 cross-town series by a score of 10-8 on Nov. 2, redshirt junior two-meter Mac Carden looked to last year as a source of motivation.“It was a tough loss [against UCLA],” Carden said. “We knew coming into the season that nothing is easy. Last year we went into the conference tournament in fourth place, and last year we had to overcome some odds, so we expect to do the same this year.”With Saturday’s matchup against Long Beach State marking the final stretch of the regular season, the Trojans seek to execute at a high level  at the end of games — both Carden and senior driver Rex Butler said the team strayed from its game plan in the fourth quarter of Sunday’s game. Butler noted the team’s shift in concentration at the end of the loss against the Bruins.“We just need to be more focused defensively,” Butler said. “That game we were just trying to win it with offense, and we made a lot of mental mistakes. We gave up a lot of easy goals in the fourth quarter, and our offense wasn’t working.”The 18-4 Trojans, who are 3-2 in Mountain Pacific Sports Federation play, will emphasize defense as they look to bounce back against the Zacchary Kappos-led 49ers. With a team-high 51 goals on the year, Kappos has helped the 49ers earn an identical 18-4 record in 2014, with a 5-1 conference record. The 49ers’ four losses came at the hands of California (twice), UC Santa Barbara and Stanford, all three of which are ranked in the top 10 in the Collegiate Water Polo Association’s most recent poll.The Anteaters, meanwhile, are 13-9 overall and just 1-5 in conference play. They’ll head into the matchup coming off a game against UC San Diego the day before, and three straight losses before that. The Anteaters are led by UCLA transfer Lovre Milos, a driver with a whopping 78 goals as of now.This weekend, USC will try to muster the resiliency that has been a theme throughout the year — the Trojans have outscored their opponents 50-23 combined in three games after losses this year.“A special thing about our team is that usually after losses, our coaching staff and our leadership really use that loss to motivate us to train a little harder and be a little more focused,” Butler said. “That’s where that resiliency comes from.”The 12-time Coach of the Year emphasized the importance of keeping these losses from flustering the team as it begins the final stretch this weekend.“It’s a process,” Vavic said. “You look at last year’s [San Antonio] Spurs, you look at last year’s NFL champions [Seattle Seahawks] — adversity is part of life, it’s part of sports. You really can’t labor on mistakes, you need to figure out what really is wrong and why it went wrong. That’s the challenge, and that’s what I love about coaching.”last_img read more
