Change may not be immediate, but it will gradually change.

Shenzhen Translation Bureau is its compilation team, focusing on technology, business, workplace, life and other fields, focusing on introducing new foreign technologies, new perspectives and new trends.

Editor’s note: The Australian fire, the African locust disaster, climate change is becoming more and more terrifying, and we are witnessing more and more related uneasiness and disasters. As a world-renowned university, Boston University has set itself the goal of achieving carbon neutrality earlier. They use the construction of greener buildings to contribute to society. This change may not be immediate, but it is gradually changing, and people in Boston or other places may also start to make clumsy efforts to repair the environment. Original text from fastcompany, author Kristin Toussain, original title “ Boston University is building the city’s largest carbon-neutral, fossil fuel-free building “.

School builds a new building for carbon neutrality

Boston’s goal is to achieve carbon neutrality by 2050, but Boston University, which occupies the city’s 135 acres, aims to be carbon neutral by 2040. The 305-foot (92.964-meter) high computing and data science center will use geothermal energy for heating and cooling as a sign of the city’s carbon neutrality goals. (Editor’s Note: Carbon neutrality refers to the total amount of greenhouse gas emissions directly or indirectly measured by a company, group or individual within a certain period of time. “Zero emissions” of carbon dioxide.)

Dennis Carlberg, Boston University ’s vice president of sustainable development at Boston University, explains that this is not because schools are highly competitive, but because if BU is not the first If this is done, it will not be possible for the city to reach its goals in time. Not only municipal buildings need to be carbon-neutral, but so is the entire city. BU is counting on a new building on campus to help schools and cities achieve this goal.

Regulation of cold and heat by geothermal wells Energy saving and environmental protection from the inside out

BU’s new Computing and Data Science Center, designed by construction firm KPMB Architects, will include a series of environmental initiatives.

This 19-story building will be carbon-free and fuel-free, with no natural gas pipelines connected to the building; instead, 31 geothermal wells, each 1,500 feet deep, will pass through a ground source heat pump Exchange heating and cooling systems. Just like the refrigerator compressor draws heat from the refrigerator, in summer, water will draw heat from the building, and then in winter, it will transfer heat from the earth to the building.

About the center’s power system, it will not be powered directly by renewable energy. But renewable energy from a wind farm in South Dakota will carry the center’s electrical load. Karlberg said that BU invested in renewable energy in that wind farm, and believes that it will have a greater impact than building more renewable energy in New England. New England has installed so much renewable energy that a new wind farm is unlikely to replace the use of coal.

The building’s offset stacking book stack shape allows a series of roof terraces and green roofs to rise all the way, instead of just planting greenery at the top. This shape has also caused some controversy. The building will be the tallest building on the Boston University campus at 305 feet and will be located on the campus Commonwealth Avenue, becoming the main resistance. “People have their own views on how it looks-I don’t think so.”

The triple-glazed window system can keep indoor heat in winter; and the exterior of the building will have fixed shadows, which can protect the interior of the building from sunlight in summer, thanks to hundredDiagonal and vertical slats of leaf window. This, coupled with a thermal energy system that uses water instead of air for heating and cooling, will make buildings more energy efficient.

The first level of the building has been elevated to what Carlberger calls a “flexible height”, which means that the building is two feet above the possible flood elevation of the nearby Charles River. To prevent sea level rise, the building is 5 feet above the city’s recommended water level. It does have a basement, because there is no room for mechanical equipment on the upper floor, but the basement also has the ability to install temporary flood protection facilities.

Climate-friendly building is expected to be the new heart of the university community

Last December, Boston University held a grand groundbreaking ceremony, but the geothermal well has been dug. After the groundbreaking ceremony, construction will begin this spring to avoid disturbing campus life. Depending on the school, this project will cost a total of $ 290 million. It is planned to open in 2022 and will house school math, computer science and data science projects.

Karlberg believes that this building will become the new heart of the BU community, a collaborative gathering place, and an example of how to build a climate-friendly building in Boston or elsewhere. Although this design may now feel novel or too novel, he hopes that it will not be the case in the future-and he agrees with other institutions to learn from this script. He said: “There are many organizations that are making great progress, but our task is to unravel the secrets of how this is done and what is important. For me, for me, what matters is , We must do our best not only to build a carbon-free and fossil fuel-free building, but also to help others do the same, because we cannot be carbon neutral by ourselves. “
