Para 3
ArtScience Museum, Singapore(新加坡艺术科学博物馆)
Nature Architecture Inspiration Functions/Significance
People whose interest is exploring the relationship between art and science will enjoy Singapore’s ArtScience Museum. The building was designed to show the connection between nature and the modern city environment in which it sits. Shaped to resemble a lotus flower, it appears to float above the waterfront promenade and the water that surrounds it. Its roof collects rainwater and channels it 35 metres down to a waterfall in the centre of the space. The water is then recycled through the building’s plumbing system. Visitors are often amazed to find themselves in an urban building that so truly captures the beauty of natural forms.

Para 4
The Eastgate Centre, Harare(哈拉雷东门大厦)
Nature Architecture Inspiration Functions/Significance
Harare’s Eastgate Centre is a superb example of biomimicry. To use biomimicry is to create structures based on natural forms and processes. Zimbabwean architect Mick Pearce was inspired to create the Centre while watching a nature documentary in which termites were constructing their nests. The insects built mounds covered in little holes designed to allow air to move freely in and out of the mounds. In a similar way, the Eastgate Centre has a “skin” covered in holes. During the day, warm air is drawn into the building through the holes, cooling as it reaches the middle of the building. At night, the heat absorbed by the wall during the day warms the cool air, creating a comfortable temperature inside. The design reduces the need for traditional air conditioning and heating systems, so the building uses less energy and costs less to run.

Para 5
The Algae House, Hamburg(汉堡藻屋)
Nature Architecture Inspiration Functions/Significance
The world’s first algae-powered building is in Hamburg, Germany. The surface of the apartment building is covered in panels that contain algae. The algae are fed with liquid nutrients and carbon dioxide to encourage them to grow. In bright sunshine, they grow faster and provide shade. The panels also capture heat from the sun and convert it into energy that powers the building. And that’s not all – the algae inside the panels can be harvested and used to produce fuel. The building therefore not only responds to its environment and uses less energy, but also reduces damage to the environment by generating its own renewable energy.

Para 6
Read paragraph 6 carefully, then answer the questions.
Why should we get inspiration from nature
Because it enables us to live in closer harmony with our environment.
To meet the needs of today while protecting the world of tomorrow may be a challenge, but even the simplest organism can help teach us how to achieve this.
