Smart surroundings

Smart City Blueprint 2.0 sets out how technology is transforming mobility, environment, government, and economy within Hong Kong.

Calculating carbon emissions

To achieve its pledge to become carbon neutral by 2050, Hong Kong has launched many initiatives to build business and citizen momentum.

The Business Environment Council has launched a Low Carbon Charter to help companies decarbonize, with a focus on establishing accurate measurements and clear targets. Meanwhile, the Environment Bureau provides a Low Carbon Living Calculator to help citizens make better choices in day-to-day activities such as eating and travel.

Siemens is supporting the Energizing Kowloon East project to demonstrate how digital solutions can improve residential areas and enhance wellbeing. For example, domestic smart meters are helping citizens to understand their energy consumption, and identify savings opportunities.

Intelligent infrastructure

Hong Kong is developing scalable and sustainable infrastructure that can support a wide range of digital applications. This is a core focus of its Smart City Blueprint 2.0, which sets out 76 initiatives spanning areas such as smart mobility, environment, government, and economy.

The first Smart City Digital Hub at Hong Kong Science Park showcases how digitalization can make infrastructure work harder for the benefit of everyone. Powered by Siemens Advanta, the innovations include a renewable energy lighting system with sensors that collect data about electricity use, energy efficiency, and the environment.

Building efficiencies

Buildings account for 60% of Hong Kong’s carbon emissions, and the city is keen to improve their energy efficiency using smart technology. For example, Siemens is helping businesses to optimize HVAC using the Demand Flow system, which offers a 95% prediction accuracy on load demand and power consumption. This capability is particularly valuable for Hong Kong’s many data centers.

It is also worth bearing in mind that Hong Kong benefits from one of the most reliable energy supplies in the world. The two main electricity providers have maintained an electricity supply rating up to 99.9999%. Among Hong Kong’s many energy sources is a wind turbine in Tai Ling on Lamma Island.
