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

Motivated Super Falcons Target Three Points against Norway

But I can say we have the team to do that here in France. The NFF has done well by ensuring good preparation for the team, with the tournaments that we played.“A lot is hanging on the first match against Norway. If we are able to get a good result, then we will take it from there.”Norway comes into the encounter with the mindset that they should be able to steamroll the African champions. Only last week, the Grasshoppers hammered another African representative, South Africa 7-2 in a friendly. And going back 24 years, at the second edition of the FIFA World Cup staged by Sweden, Norway lashed Nigeria 8-0 in a group stage encounter in Helsinborg.Head Coach Thomas Dennerby is asking his girls to take it one match at a time and develop a positive mindset about the finals.“A positive mindset is key to what we are here for. You must believe in yourselves and have confidence in what you can do here. You must give it your best,” he told the players after yesterday’s training session at the Stade Jean Boucton in Reims.A good number of the Nigerian mainstream play their club football in the Scandinavia region, to which Norway belongs.These include defender Osinachi Ohale, Ngozi Ebere and Faith Michael, midfielders Rita Chikwelu, Ngozi Okobi, Ogonna Chukwudi and Halimatu Ayinde, and forwards Anam Imo and Rasheedat Ajibade.These players should, indeed, have a very good idea of how Norway will set up and activate at the Stade Auguste-Delaune on Saturday night.Pacy forward Asisat Oshoala, who has sealed a permanent move to FC Barcelona Ladies, was on Wednesday appointed team assistant captain.The top scorer and most valuable player of the FIFA U20 Women’s World Cup in Canada in 2014 has extra motivation to take the finals in France by storm.Apart from sponsoring the team to preparatory tournaments in China, Cyprus, and Spain, capped with a two-week residential camping at the Avita Resort in Austria, the NFF beefed up the team’s technical crew, with the appointment of Per Harlsson as conditioning coach and Matti Demegard as video analyst.In China, the African champions played two matches, losing to the host nation but defeating Romania.In Cyprus, they lost to Belgium and Austria but defeated Thailand and Slovakia. In Spain, they narrowly lost to the Canadian national team.While in Austria, they defeated Hungarian top division club Viktoria and also defeated a Slovenian top club, Pormuje.Saturday’s encounter between Nigeria and Norway starts at 8pm.center_img FRANCE 2019After the Nigeria Football Federation (NFF) cleared all their outstanding entitlements, the Super Falcons have put all their worries aside and are now determined to take all three points off the Grasshoppers of Norway in their first match of the 8th FIFA Women’s World Cup finals in Reims on Saturday.Falcons are one of only seven teams to have made it to every edition of the FIFA Women’s World Cup finals since the inaugural competition in 1991. Falcons have made it out of the group stage only once previously, and that was 20 years ago.last_img read more
