How Singapore Uses Science to Stay Cool

The video discusses the urban heat island effect, highlighting its health risks and the exacerbating role of urbanization and climate change. It introduces the Cooling Singapore project, which aims to mitigate these effects through innovative strategies like district cooling systems and increased vegetation. The project also involves creating a digital urban climate twin to test solutions. Singapore's efforts in urban greening and energy-efficient architecture are showcased as models for other cities.

What is the urban heat island effect primarily caused by?

• High altitude of cities

• Proximity to large bodies of water

• Heat absorption by materials like asphalt and concrete

• Increased vegetation in urban areas

How does Singapore's district cooling system benefit the environment?

• It reduces electricity usage and emissions

• It eliminates the need for refrigeration

• It increases the use of traditional air conditioners

• It relies solely on solar power

What is one of the key benefits of increasing urban vegetation?

• It reduces the need for public transportation

• It raises the temperature in urban areas

• It provides more space for construction

• It helps mitigate the urban heat island effect

What is the goal of Singapore's plan to plant 1,000,000 trees?

• To increase urban heat

• To reduce the urban heat island effect and connect people to nature

• To replace existing green spaces

• To create more space for urban development

What is a key feature of the digital urban climate twin model?

• It only models the geometry of buildings

• It tests the impact of design elements on urban heat

• It focuses solely on transportation systems

• It is used exclusively for rural areas

Which of the following is NOT a strategy mentioned for reducing urban heat?

• Using water as a thermal buffer

• Allowing wind flow through clear areas

• Increasing the use of combustion engines

• Shading windows

What is the potential energy production from renewable sources on building facades in Singapore?

• Up to 20-25% of the city's electricity needs

• Up to 10% of the city's electricity needs

• Up to 50% of the city's electricity needs

• Up to 5% of the city's electricity needs
