Inventory of energy-saving building cases, green and environmentally friendly buildings

The materials used in energy-saving building structures must have sufficient strength, durability, envelope structure, thermal insulation, and waterproofing to reduce environmental pollution. It uses low-pollution materials, uses clean energy, and can be recycled and reused. The decoration of the building should be simple and can reflect the feeling of home. Next, the editor will introduce to you some famous energy-saving building cases.

What is an energy-saving building?

Energy-saving building refers to following the basic methods of climate design and energy saving, planning zoning, groups and individual buildings, building orientation, spacing, solar radiation, wind direction After studying the external space environment, the main indicators of the designed low-energy building are: the building plan and layout should be conducive to natural ventilation, and the greening rate should be no less than 35%; the spacing between buildings should ensure that each household has at least one living space. On a cold day, you can get full window sunlight for 2 hours.

Energy-saving building cases

1. Diangu Jinjiang Hotel

Diangu Jinjiang Hotel also applies another renewable energy building application technology, sewage source heat pump technology . The urban sewage is treated and used for heating, cooling, etc. of the entire hotel, so that the sewage can be recycled and the utilization efficiency of renewable energy can be improved. It can utilize 7.37 million tons of reclaimed water every year. The system operation cost is 1.885 million yuan cheaper than the water-cooled screw plus steam system. It can save 1.88 million kilowatt hours of electricity every year, save 752 tons of standard coal, reduce carbon dioxide emissions by 546 tons, and sulfur dioxide emissions by 16.54 tons. Nitrogen emissions were 7.52 tons and soot emissions were 12.78 tons.

2. China Pavilion at the World Expo

The Chinese National Pavilion in the shape of a bracket is known as the "Crown of the East". In summer, the top-floor building can shade the bottom-floor building and play a certain cooling role. In addition, ecological agricultural landscape technology has been applied, which can effectively insulate and reduce building 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. A number of environmentally friendly technologies such as self-shading, solar energy collection, and rainwater collection have been applied.

3. Taipei 101 Building

The 508-meter-tall Taipei 101 Building has been announced to apply for "LEED Platinum" certification of the world's green building environmental standards. The entire floor is integrated with garbage recycling, Water, electricity, and lighting equipment are integrated into one, which can save 3.3 million kilowatt-hours of electricity a year, reducing water use by 50% than before. The building will be divided into zones to measure air quality, monitor humidity, increase green area, etc. Building 101 will also adopt a neighborhood park to reduce the heat island effect and increase its contribution to the environment. Generally speaking, 101 invested a lot of manpower and material resources to apply for LEED Platinum certification in order to provide the best quality of the building's space with the lowest energy consumption and hope to lead the trend of green energy and environmental protection in high-rise buildings in Taiwan and even Asia.

4. Hangzhou Low-Carbon Science and Technology Museum

Hangzhou Low-Carbon Science and Technology Museum is designed and constructed in accordance with the "National Green Building Three-Star" standard and is a veritable low-carbon building. The total construction area is 33,700 square meters, and 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 material transportation; natural and recyclable materials will be used; solar photorecovery materials will be used as much as possible for the curtain wall. This museum is expected to be completed in 2011. Once completed, it will be the world's first science and technology museum with a low carbon theme.
