A net zero carbon building is extremely energy efficient because it generates enough carbon-free renewable energy to be self-sufficient. Sustainable buildings designed by these creative thinkers have been unveiled around the world, setting a new gold standard for net-zero carbon buildings. From San Diego in the United States to Copenhagen in Denmark, discover how environmentally friendly buildings making waves on the world stage bring new ways of thinking to the world.
CopenHill (Denmark, Copenhagen)
Opened in 2019 on Copenhagen's Amager island,CopenHillis one of the world's most sustainable waste incinerators, with no carbon dioxide emissions and operating at 110% efficiency.CopenHillalso provides low-carbon electricity and district heating to nearly 600,000 people.
Designed by BIG & SLA, the project, also known as "Amager Bakke", is a waste-to-energy plant, as well as a large urban leisure center, including lush natural parks, ski slopes, mountaineering, and the world's highest rock climbing wall and the Environmental Education Center.
The creation of a nature-filled green activity park on the 88-meter-high waste-to-energy plant has never been achieved before. The steep slope of the roof up to 45 degrees places high demands on the plant and landscape design. The complex weather conditions make the survival requirements of trees and plants very difficult, and the heat emitted by the large energy boiler under the roof must be solved, so SLA designed several Design solutions based on nature and tested with different types of vegetation and materials.
By studying different types of habitats to meet the challenging living conditions in the natural park and to provide the optimal microclimate for visitors on the roof. As a result, lush hardy plants are planted in abundance, making the space usable year-round, while creating a sensual and rational space on the roof.
Hotel Marcel (New Haven, CT, USA)
Although there are a few exceptions, most Brutalist buildings are not new. In fact, they are decades old, and the concrete Hotel Marcel in New Haven, Connecticut, which opened on May 12, 2022, is a prime example. The restaurant may be new, but it is classified as a typical Brutalist masterpiece, originally designed by the father of modernism, Marcel Breuer himself.
Marcel Breuer, who was born in Hungary and studied at the Bauhaus, designed the Marcel Hotel in 1970, but at the time the building was the headquarters of the Armstrong Rubber Company. After the headquarters was withdrawn, the building sat empty for decades. Eventually, after a large piece of the building was demolished, other parts began to collapse.
However, local real estate developer and architect Bruce Redman Becker brought new life to the building in 2020. He bought the property (with Dutch East Design) and transformed it into the 165-room Marcel Hotel over the next two years, paying homage to the building's original vision for excellence. The hotel is also highly sustainable, with nine historic suites, an American restaurant and bar with tableside service, a library lounge and 7,000 square feet of meeting space. This passive building certified restaurant is located in a LEED Platinum certified net zero energy building.
La Jolla Commons (San Diego, CA, USA)
Designed by Paul Danna, partner at AECOM, the 13-story, 302,261-square-foot building is home to U.S. brokerage LPL Financial, in a seaside town that has been in operation since 2008. Proud to be the only net zero building in La Jolla. The exterior of the office building is dominated by a glass façade, double glazing is energy efficient, and the annual carbon neutrality goal is achieved through a high-efficiency design and on-site fuel cells that generate more electricity than the building and tenants use. Not to mention, this sustainable architectural marvel in Southern California houses a supply air system under the floor and an extensive recycled water network with water for cooling, irrigation and toilets.
BEEAH Group Headquarters (Sharjah, United Arab Emirates)
Recently, the new headquarters of BEEAH Group, designed by Zaha Hadid Architects, was officially opened. To meet LEED Platinum standards and achieve net zero emissions, the building is powered by solar arrays and operates in conjunction with next-generation technology. It will serve as the management and administration centre for the group, setting a new benchmark for the workplace of the future.
Based on the two-pillar strategy of "sustainability" and "digitization", the Group's business covers six key areas, including waste management and recycling, clean energy, environmental consulting, education and green transportation. The headquarters will be a new milestone for the group, marking their long-standing innovation in Sharjah and around the world. As a business base, the Group will respond to important future developments in the industry with a more diversified identity.
As a result, the design is modeled on a series of interconnected “dunes” that, through their orientation and form, respond to the site context and optimize local climatic conditions. The building is integrated into the Al Sajaa desert landscape of Sharjah, echoing the surrounding undulating sand dunes shaped by prevailing winds. By controlling the amount of glazing, the building ensures that all interior spaces have ample sunlight and views, but are not directly exposed to the scorching sun. Two "dune" volumes house the public and administrative departments, as well as administrative areas connected by a central courtyard. This courtyard is both an "oasis" in the building and part of the building's natural ventilation strategy.
The 15-meter-high dome defines the entrance space, further enhancing the natural ventilation of the interior and guiding the entry of light. In addition to the central courtyard and open-plan offices, the headquarters features smart meeting rooms, an immersive visitor center and an auditorium. With sustainability at its core, the 9,000-square-meter headquarters uses a wealth of local materials and is paired with future-proof technologies to achieve LEED Platinum standards overall, with net-zero emissions and minimal energy consumption. Fiberglass reinforced panels reduce solar radiation, while cooling systems for the floors and glass facades work together to regulate the interior temperature for optimum comfort. Additionally, a site water treatment system filters wastewater to minimize consumption. Its solar panels charge Tesla battery packs to meet the building's daily energy needs.
National University of Singapore
One of the newest buildings at the National University of Singapore, the School of Design and Environment Education Building 4 (SDE4) has a striking design and is the first new net-zero energy building in Singapore.
Designed by Serie Architects in collaboration with Multiply Architects, SDE4 aims to be what the architects describe as a "prototype of sustainable design", demonstrating Singapore's desire to promote education and sustainable development in Southeast Asia. The new building is six stories tall and covers nearly 30,000 square feet, setting an example toward a more sustainable future journey.
It is also a sleek, sleek building with plazas, open-air public spaces, studios, research centres, cafés and libraries set in a lush jungle.
Atlassian Headquarters (Sydney, Australia)
The Atlassian headquarters, which is about to become "the world's tallest mixed-timber building", is under construction in Sydney, Australia. Designed by SHoP in collaboration with BVN, the 40-storey tower is expected to be completed in 2025 and will later provide a new innovation space for tech giant Atlassian. New York-based SHoP, BVN Australia and Eckersley O'Callaghan Structural Engineering. The new Atlassian headquarters will break all records. The world's tallest mixed-timber building under construction will be the new home for thousands of tech workers.
A mix of wood, glass and steel will be used for both the outdoor and indoor areas of the tower, which "will use an energy-efficient approach, featuring natural ventilation and large green terraces, allowing people to be in close contact with nature. The project meets the Atlassian's values are to use 100% renewable energy and achieve net zero emissions. In fact, the headquarters is aiming for a 50% reduction in carbon content in buildings compared to traditional buildings, which when completed, will be more energy efficient than traditional buildings. consumption reduced by 50%.
Solar panels in the vertical façade will help generate green energy on-site. Ultimately, the building will feature built-in solar panels on the façade and run on 100% renewable energy. The new hybrid timber structure achieves Atlassian's goal of achieving net zero carbon emissions by 2050, "significantly reducing carbon emissions and significantly reducing the building's carbon footprint". In addition, the façade integrates a power generation system with self-shading to reduce direct heat gain inside. Combined with the extensive use of timber, the innovative façade enables the project to take advantage of Sydney's temperate climate to help reduce carbon emissions and generate on-site energy.
At approximately 180 meters / 590 feet high, the project is the tallest commercial mixed-timber building in the world. In the design, the structural elements of the building are linked to the facade. Conceived by SHoP/BVN and Eckersley O'Callaghan, this approach results in a steel exoskeleton that supports the giant floors. Additionally, the timber-framed building provides a warm and inviting environment for employees and visitors.
