Questions & Answers

Q: Why is there a significant difference in energy wastage between the US and China?

The US has maintained stable energy consumption due to more efficient production and transportation systems. However, China's rapid growth has led to a lack of efficiency in these areas, resulting in higher energy wastage.

Q: How can urban areas and buildings minimize energy wastage and enhance thermal comfort?

By adopting a human-centric approach to design, paying attention to details, and utilizing computational tools, urban areas and buildings can ensure optimal energy efficiency and thermal comfort.

Q: Can you provide examples of successful energy-efficient buildings?

The Singapore National Library building was designed to be 17% below the norm in terms of energy consumption. Through adaptability and future-proofing, the building now operates at 20% below the initial target. Another example is the recently completed building on our campus, designed to be a net-zero energy building.

Q: How can the concept of sustainability be expanded beyond energy efficiency?

Moving beyond energy efficiency, the next challenge is to focus on wellness in buildings. This requires collaboration with medical professionals, public health experts, and social scientists to create environments that prioritize occupant well-being.

Summary & Key Takeaways

• The global urban population is projected to reach 60% by integrating over three million people into cities every week, with Asia experiencing the most significant growth.

• Energy consumption in the US has remained stable, while China has seen significant growth but struggles with energy wastage due to inefficient production and transportation.

• To address energy wastage and ensure thermal comfort, urban areas and buildings need to adopt a human-centric approach to design, paying attention to details and utilizing computational tools.
