Energy-efficient buildings are low-energy buildings designed after following the basic methods of climate design and energy conservation, and studying the building planning zoning, groups and units, building orientation, spacing, solar radiation, wind direction and external space environment.
According to some building energy experts, buildings consume about 40% of the world’s energy and account for 21% of total global carbon dioxide emissions, while only 4% of China’s approximately 43 billion square meters of existing buildings have adopted advanced energy efficiency improvements. Here are fifteen energy efficient buildings around the world to share with you.
This house is known to the public in Europe, it is located in Germany and is known for its good use of solar energy. Built by the Department of Applied Sciences at the University of Rosenheim, the project’s energy products exceeded its needs. How does it work? Through the use of various green technologies such as solar panels, vacuum insulation panels, efficient mechanical systems and natural ventilation.
Chuckanut Ridge House
Many people are afraid that solar panels will have a negative effect on the design of the building. In this example, the panels are freestanding, which is our most conventional solution. It is located in Washington and was designed by designer Prentiss.
Situated on top of a hill, this home offers a beautiful view of the Russian River Valley. To build this home, architect Dowling considered using the most sustainable materials and energy efficient systems.
Beautiful and exquisite house from Pietro Lazo with a hypnotic view next to the building. Based on green and sustainable features.
Aarhus, located in Denmark, is an environmentally friendly building that focuses on low energy consumption and low carbon. To our surprise, this building produces more energy than it consumes.
From the work of Iranian architect Glenn, located in the Venice Canal, Los Angeles, California. The challenge of the project was to maximize outdoor space by creating a seemingly upside down tray suspended from the ground.
This peculiar structure was built in the Swiss countryside and has two floors, mainly to pay attention to the privacy and sunlight of its inhabitants.
This incredible beach house was created in Costa Rica. The house is located on a hill above sea level, at least 20 km away from any town, and its sustainable existence was one of the biggest challenges for the architects, as the house had to exist independently in a humid environment.
This house is a very interesting and sustainable building project, built near Bozen, Italy, at an altitude of 1200 m. Its design solution is based on a green and low energy consumption, the Fincube house is a 470,000 sqm living space that resembles a small apartment. The interior design is small, but it has everything that city life has to offer.
Casa No Gere
This building, from the architect Roberto Zuccori, is located in an unconventional setting, deep in a Portuguese park. The owner asked to live in such an environment and these architects respected his request. The result? In the process of construction, not a single tree was cut down, is environmentally friendly, outside the simple, but inside is modern and comfortable.
International New Energy Market Solar Thermal Pavilion
Many people may not know this building, it is exactly such a shell-shaped building, the overall lighting rate of about 90%, such a high lighting rate in addition to the location of the factors, the entire building has 75% transparency, all internal light-transmitting panels are paved with light collector panels, the roof of more than 20,000 square meters placed up to 15,000 automated ray tracing panels, in addition to wind power supplementation. This will enable the building to operate 24 hours a day, and the integration of heating and power supply, which will save one million kilowatt hours of electricity per year, reduce carbon dioxide emissions by about 600 tons, and reduce the building’s energy consumption by about 80 percent. The building is expected to be completed and put into operation in 2011.
Expo China Pavilion
The China Pavilion in the shape of a dome is known as the “crown of the East”. In summer, the top floor of the building can shade the ground floor of the building and play a certain role in cooling down. In addition, the ecological agricultural landscape technology is applied, which can effectively insulate the building and reduce energy consumption by more than 25%. The design of the Expo Center follows the “3R” principle, vigorously enhancing the thermal insulation of the building envelope and reducing heat loss. It applies a number of environmental protection technologies such as self-shading, solar energy collection and rainwater collection.
Texas Sun Valley Micro Row Building
It is known as the world’s largest solar energy building, the total construction area of the Sun and Moon Altar micro row building reaches 75,000 square meters, which is the first in the world to realize the perfect combination of solar energy hot water supply, heating, cooling, photovoltaic power generation and other technologies with the building, the overall energy efficiency of the building reaches 88%, saving 2,640 tons of standard coal, saving 6.6 million degrees of electricity and reducing pollutant emissions 8672.4 tons per year, which is the world’s largest solar energy building. It is the first of its kind to realize the perfect combination of solar hot water supply, heating, cooling, photovoltaic grid-connected power generation and other technologies with the building.
Low Carbon Science and Technology Museum, Hangzhou
The Hangzhou Low Carbon Science and Technology Museum is designed and built according to the “National Green Building Three-Star” standard, and is a truly low-carbon building. With a total construction area of 33,700 square meters, the total investment is expected to exceed 400 million yuan. In terms of building materials, local building materials will be used first to reduce carbon emissions during transportation; natural and recyclable materials will be used; and solar photovoltaic materials will be used for the curtain wall as far as possible. The pavilion is expected to be completed in 2011, once completed will be the world’s first science and technology museum with a low-carbon theme.
China’s first ultra-low energy demonstration building was completed in the east part of Tsinghua University campus. The “green” building focuses on using nearly 100 of the most advanced building energy-saving technologies at home and abroad. “Seven different energy-saving systems are used on just two walls, and any component can be removed or replaced at any time,” Jiang Yi, an academician from the Chinese Academy of Engineering and a professor at Tsinghua University, said of the building.
