Office building uses 112 ‘smart’ chimneys to regulate light, air and energy

Comments Off on Office building uses 112 ‘smart’ chimneys to regulate light, air and energy

Mario Cucinella Architects has created a sustainable public building that uses several active and passive elements to lower its environmental footprint. Specifically, the new timber-clad headquarters for the Regional Agency for Prevention, Environment and Energy (ARPAE) uses a soaring rooftop made up of 112 smart chimneys to regulate its air, light and energy so that the building relies on minimal technical systems. At more than 53,000 square feet, the immense public works building features a central courtyard. Its cladding is made up of thin timber panels that top a ground floor with floor-to-ceiling glass panels, creating a natural harmony with its woodland surroundings in the small city of Ferrara, in northern Italy. Related: 3D-printed home inspired by a wasp’s nest is made of local clay The architect chose the building’s materials based on their ability to help the structure reach a “maximum level of environmental sustainability.” Mario Cucinella explained, “The building in Ferrara explores the relationship between form and performance, that makes it the first hybrid public building in Italy.” The stand-out characteristic in the design is, without a doubt, its eye-catching rooftop, which is comprised of 112 chimneys. An essential element in regulating the building’s energy use, each chimney features a skylight that lets natural light and air filter down into the spaces below. Some of the chimneys feature solar panels that generate ample energy for the building. The passive building system also acts differently in the summer and winter months. During the hotter months, the chimneys constantly move air through the interior, creating a healthy working space for employees and visitors. In the winter months, they operate more like a greenhouse, where they accumulate solar heat to keep the spaces warm. All in all, the unique system helps the building enjoy a comfortable temperate year-round all while reducing energy demand. + Mario Cucinella Architects Images via Mario Cucinella Architects

Los Angeles air quality improves amid pandemic

Comments Off on Los Angeles air quality improves amid pandemic

There is one positive impact of the tragic coronavirus pandemic — Los Angeles is experiencing its longest stretch of good air quality since 1995. On April 7, Swiss air quality technology company IQAir cited LA as one of the cities with the cleanest air in the world. While the notoriously smoggy city is on lockdown, highway traffic has dropped 80% throughout the entire state of California, which probably accounts for much of the improvement. “With less cars on the road and less emissions coming from those tailpipes, it’s not surprising to see improvements in the air quality overall,” Yifang Zhu, professor of environmental health science at UCLA, told CNN. Zhu and her team of scientists measured a 20% overall improvement in southern California’s air quality between March 16 and April 6. They also recorded a 40% drop in PM 2.5 levels. This microscopic air pollutant is linked to both respiratory and cardiovascular problems, especially in the very young and very old. A recently released Harvard study linked PM 2.5 exposure to an increased likelihood of dying from COVID-19 . Related: Coronavirus and its impact on carbon emissions All over the world, scientists are noting that cleaner air is a side effect of the pandemic . Satellite images have revealed much lower concentrations of nitrogen dioxide over industrial areas of Europe and Asia in the past six weeks. The drops in nitrogen dioxide levels over Wuhan — a city of 11 million — and the factory-filled Po Valley of northern Italy are especially striking. “It’s quite unprecedented,” Vincent-Henri Peuch, director of the Copernicus Atmosphere Service, told the Guardian. “In the past, we have seen big variations for a day or so because of weather. But no signal on emissions that has lasted so long.” Alas, when lockdowns lift and Angelenos return to the highways, the pollution will likely return. Zhu hopes that this glimpse of clear, blue skies will inspire people to work for better air quality post-pandemic. “From the society level, I think we need to think really hard about how to bring about a more sustainable world, where technologies and policies come together to bring us cleaner energy ,” she said. “So that the air that we’re breathing will stay as clean as what we’re breathing today.” Via CNN and The Guardian Image by Joseph Ngabo

Swedens tallest timber building could save 550 tons of CO2

Comments Off on Swedens tallest timber building could save 550 tons of CO2

Scandinavian-based architecture firm C.F. Møller Architects has raised the bar for sustainable architecture with the recent completion of the Kajstaden Tower, Sweden’s tallest timber building. Located in Västerås, about an hour outside of Stockholm, the landmark building rises 8.5 stories in height and was built almost entirely from cross-laminated timber. The architects estimate that the use of solid timber instead of concrete for construction translates to 550 tons of carbon dioxide savings over the building’s lifetime.  Commissioned by Slättö Förvaltning, the Kajstaden Tower was constructed as part of a new central residential neighborhood near the waterfront of Öster Mälarstrand. Along with the record-breaking, solid-timber landmark, the new sustainably minded neighborhood includes an electric boat sharing system in the marina. Related: C.F. Møller’s Storkeengen tackles climate challenges in a Danish town In addition to reducing the building’s carbon footprint, the use of CNC-milled solid timber and glulam for all parts of the building — including the walls, joists, balconies, lift and stairwell shafts — results in an airtight and energy-efficient building envelope without added insulation. The timber frame was also fast to raise; each floor, which contains four apartments, took four craftsmen an average of three days to put together. Mechanical joints and screws were used so that the building can be later taken apart, and the materials can be reused.  “The building in Kajstaden constitutes a new chapter in the history of construction, as it is currently Sweden’s tallest solid-timber building,” said Ola Jonsson, associate partner at C.F. Møller Architects, which is also part of the Nordic Network for Tall Wood Buildings. “Through research projects and our other timber projects, we have focused on innovation and contributed toward developing ways of realizing high-rise buildings made of timber. Industrial timber technology also provides architects with better tools for designing beautiful houses that boast a high degree of detail.” + C.F.
