  43. 43. Hong Kong 40 Storey Office Tower - Zero Carbon for Zero extra Capital Cost Aims to rewrite: • Rewrite conventional design principles • Rewrite Passive design principles • Rewrite Fitout standards • Rewrite planning & policy • Rewrite building environmental Assessment method • Rewrite expectations for all the stakeholders  And establish a new standard for sustainability. What’s next? Carbon Negative? Can this be naturally ventilated? Integrated Arup design scope including:  Concept design  Fitout brief  Building planning  Initial cost advice  Detailed design  Construction drawings & specifications  Review of site works  Checking commissioning on behalf of developer
  44. 44. Conclusion • Has to be a greater sense of urgency. • What we have been doing and are planning to do is not enough • There are no quick fixes and a lot to be done globally, regionally and locally. • Challenges abound but also lots of opportunities. • Technology is already here. Collectively we can play our part in this immense challenge. yong-wei.chan@arup.com
