This, in part, is achieved by a state-of-the-art, AI-enabled building management system called Neuron, which performs a similar role to the ICC's team but uses a type of AI called machine learning.
The building's energy intensity is about 29% lower than a typical Hong Kong high-rise office building. This 48-storey skyscraper, completed in 2018, was designed and constructed according to the highest green building and human health standards.
And the team is committed to achieving the net zero carbon emissions by 2050 target set by the government.Īnother pioneer of Hong Kong's green building movement is One Taikoo Place. Since 2012, through various energy saving measures, ICC has conserved 15 million kWh of energy, equivalent to the total annual electricity consumption of more than 4,500 three-member households, and a reduction of 10,000 tonnes of carbon emissions. It also means they can control the air distribution to different office floors in order to further optimise the energy usage of the building. But with smart IoT devices built into the building's air-handling systems, the building's team is able to monitor each floor in real-time to see the temperature, levels of pollutants, and how much cooling energy is being used.

While floor-to-ceiling windows enable better views and natural light, this can also create a greenhouse effect caused by solar radiation, and air-conditioning systems require huge amounts of energy to operate.Īt ICC, air-con consumes a staggering 70% of the building's total energy. Keeping skyscrapers cool is perhaps the most difficult challenge, especially since most are covered in glass. "We can see the energy performance across every zone in the building and optimise the system to perform better." "We use Internet of Things (IoT) technology to analyse big data collected through a mobile digital system for energy efficiency optimisation in the building," says Edward Tsui, managing director of Intelligent Technologies, which oversees the ICC's IoT data system. Informed by the data, the property management team is able to shut down certain facilities, including lights, lifts and escalators when they are not needed, in order to save energy. This network provides large quantities of data that enable real-time energy consumption monitoring. Inside the 118-storey building, a network of sensors is installed, often wirelessly, across different facilities and equipment, including lighting, elevators, escalators and air-conditioning units. Making use of the latest smart technologies to be more energy efficient, the ICC is recognised in the top 3% of green buildings around the globe. You need look no further than ICC, which at 484m (1,590ft) is the city's tallest skyscraper and also its tallest green building. The problem leaves many asking how sustainable skyscrapers can really be.īut there are signs of hope in Hong Kong, which has a thriving green building movement and is committed to making its vast number of skyscrapers more energy efficient. But in a world responding to the climate crisis, towering skyscrapers that use massive amounts of energy and materials to construct and operate may look increasingly out of place – particularly given that Hong Kong itself has set a target to be carbon neutral by 2050. With limited land supply, building upwards is Hong Kong's only option. While many are impressive feats of construction and have become iconic features of the skyline, the city's 42,000 buildings – including about 8,000 high-rises, of which more than 1,500 are skyscrapers exceeding 100m (328ft) in height – consume up to 90% of the city's electricity and contribute to 60% of the city's greenhouse gas emissions.
In fact, Hong Kong is home to more skyscrapers than anywhere else. In every direction you look, countless high-rise buildings are stacked side by side, clustered together, like a real-world version of the game Tetris. Looking out over Hong Kong's iconic skyline from the viewing deck of its tallest skyscraper, the 118-storey International Commerce Centre (ICC), it's clear why Hong Kong is known as the world's most vertical city.
