Sustainable architecture needs technology and tradition

In recent years, the debate on sustainable buildings has intensified due to the unequivocal impact of the built environment on climate change. The common response to this challenge is to introduce technological fixes to reduce energy consumption, either through insulation or high-efficiency heating or cooling. However, several architects today argue that we should more radically rethink modern architecture and re-embrace local and traditional designs to make our built environment inherently more sustainable.

Our observations

  • In 2017, the International Energy Agency (IEA) reported that buildings are responsible for 36% of global final energy consumption and emit nearly 40% of global CO2 emissions. After the industrial sector, buildings have the second biggest impact on climate change and, with energy demand from buildings expected to rise at nearly 3% per year, this impact will only intensity if action falls behind.
  • The global crisis of climate change triggered the debate around sustainable buildings, with a specific focus on reducing the carbon footprint of the built environment. This has led to a triple response of greening energy production (e.g. wind and solar), improving the insulation of buildings and adding high-tech solutions to further reduce energy demand (e.g. smart thermostats and zonal heating).
  • In response to climate change concerns, several sustainable housing initiatives have emerged, such as the zero-carbon house, the passive house. Each of these reflect the tendency of modern architects to turn to high-tech solutions in addition to otherwise conventional, non-sustainable architecture.
  • Before the industrial revolution, architecture was vernacular (i.e. local, traditional and functional) in that it relied on local materials and was based on local designs that suited local (climate) conditions. Following the industrial revolution, steel and concrete allowed for greater freedom to design and build buildings for an advancing society, with a strong focus on cost-efficiency and functionality. From the late 19th century, architecture was further fueled by electric equipment (e.g. electric lights, central heating or air conditioning). As a result, buildings turned into uniform and mostly square shapes that have little concern for air quality, water or energy use. It was only in the last decades that we started documenting the ecological effects of our lifestyle.
  • Among other architects, Sandra Piesik argues that we should re-embrace elements from traditional vernacular architecture, such as shapes that provide natural ventilation, as these allow us to design buildings that are intrinsically more sustainable (e.g. require less energy for heating or cooling). On a different note, Bjarke Ingles seeks to integrate these kinds of ideas with new technology into a concept of hedonistic sustainability in which sustainable architecture does not imply any compromises in terms of cost or functionality.
  • Traditional architecture not only provides clues for saving energy, it can also learn us about dealing with ongoing climate change. This is true for designs that include natural shading or ventilation, but also for dealing with extreme weather events. In Tonga, for instance, traditional curved roofs are able to withstand storms and cyclones due to their aerodynamics properties.

Connecting the dots

The growing awareness of the vast climate impact of the built environment and the subsequent debate on sustainable buildings, homes and commercial property, has created momentum for the development and implementation of sustainable solutions. However, architects are stuck in an architectural lock-in, characterized by the building of basic, cost-efficient, uniform square-shaped buildings that have little to do with local (climate) conditions. As a result, to make these buildings livable or workable, they rely heavily on additional technology (e.g. electric lights and climate control systems) which increases their energy consumption. There has been much progress in terms of improving these technologies, e.g. making them more energy-efficient, and they are very valuable to making the current stock of buildings more sustainable. However, when it comes to new buildings, they can only be one part of the solution. The problem is that these add-ons only address the symptoms of flawed, non-sustainable architecture, rather than the root cause.

Traditional architecture not only provides clues for saving energy, it can also learn us about dealing with ongoing climate change

In response, several architects now argue for a re-embrace of (elements of) traditional, vernacular, architecture that actually takes into account local conditions and local needs. Such design features can include exploiting natural light and ventilation by the specific placement of windows and walls (e.g. mashrabiya, projecting windows that allow cool air to flow in from relatively cool streets, or Iranian windcatchers). Traditional materials can also be used for their intrinsically useful properties (e.g. reed for insulation). One example of a modern building that makes use of such traditional principles is Bjarke Ingles’s skyscraper in Shenzhen (tropical climate). It uses 30% less electricity by playing with dress-like facades to block sunlight from the south, while still maximizing daylight. Beyond single buildings, vernacular architecture also provide clues for smarter spatial planning. In southern Taiwan, for instance, traditional villages were built on an east-west axis to make use of prevailing winds for ventilation and cooling.
To be clear, using elements from vernacular architecture does not mean that modern technology has no role to play. By contrast, the combination of tradition and high-tech would most likely provide the best results. For instance, digital modeling techniques can factor in sunlight, prevailing winds, airflow and turbulence and help optimize designs. 3D printing provides unprecedented freedom to build any design while minimizing materials use. As such, high-tech can actually facilitate and optimize the old wisdoms of traditional architecture.

Implications

  • New architectural design principles may have consequences for the architectural supply chain. Materials use can be minimalized and there will be an increasing focus on circular buildings that allow for high-value reuse of materials or even the wholesale reuse of (elements of) constructions.
  • Theoretically, building sustainably on the basis of these principles could result in cost-efficient solutions as less additional equipment is necessary. However, this is not a given per se, since these buildings may require more space or material to be realized in the first place. In any case, the construction costs alone don’t tell the full story of a building’s life cycle and a more comprehensive approach to cost is necessary. More specifically, both architects and project developers will have to take into account the energy costs over the lifetime of a building and adopt a total cost of ownership approach to buildings (something that is probably “easier” for commercial property than for homes).
  • Vernacular architecture is local and traditional. Global warming may, however, call for vernacular design elements in places where those designs were never used (or needed) before and this could result in resistance against such unfamiliar esthetics. Moreover, in some cases there may be a need to change building codes to allow for these new, “out-of-place”, designs.

The implementation of 5G is important for the upgrade of Alibaba & Tencent’s services

5G is the next generation of ultra-fast wireless technology, offering faster data rates, reduced latency, energy savings, cost reductions, higher system capacity, and massive device connectivity. It is expected to power industrial applications such as smarty city infrastructure and the industrial internet, but can also impact consumer services. For example, 5G will enable Tencent’s gamers to seamlessly stream PC and console-quality games on their smartphones without sacrificing processing power or battery life. For Alibaba’s short-video platform Youku, a 5G connection would mean that users can send high-resolution 4K video within a few seconds.

In fear of dependency on Western hardware, Alibaba has set up a semiconductor division

Resembling the States’concern, both Ma’s have outspoken their fear of western depencency when it comes to core technologies:

Alibaba’s Ma:

If we do not master the core technologies, we will be building roofs on other people’s walls and planting vegetables in other people’s yards.

Tencent’s Ma:

[China]’s digital economy will be a high-rise built on sand and hard to sustain if we don’t continue to work hard on basic research and key knowledge, not to mention the transformation from old to new forms of drivers or high-quality development.

In reaction, Alibaba’s R&D arm DAMO (Academy for Discovery, Adventure, Momentum, and Outlook) has set up its own semiconductor manufacturing business and unveiled its chip in July 2019. The chip is designed to process AI tasks such as image, video and voice analysis and will be used for tasks such as autonomous driving, smart cities and smart logistics.

Similar to the state’s concerns, Tencent’s and Alibaba’s Ma’s have expressed their fear of western dependency when it comes to core technologies.

“If we do not master the core technologies, we will be building roofs on other people’s walls and planting vegetables in other people’s yards.”
– Jack Ma (CEO Alibaba)

“China’s digital economy will be a high-rise built on sand and hard to sustain if we don’t continue to work hard on basic research and key knowledge, not to mention the transformation from old to new forms of drivers or high-quality development.”
– Pony Ma (CEO Tencent)

The chip is designed to process AI tasks such as image, video and voice analysis and will be used for tasks such as autonomous driving, smart cities and smart logistics.

Alibaba and Tencent and Censorship

Within their services and products, Tencent and Alibaba help the government by censoring keywords deemed politically sensitive, while in-house censors also delete posts and accounts. Tencent is quite active in censoring, as the company scored a zero out of 100 for WeChat’s lack of freedom of speech protection and lack of end-to-end encryption in a 2016 Amnesty International report on user privacy.

Alibaba and Tencent have high hopes for the cloud

For Tencent and Alibaba, the cloud started as a crucial component of their internal economy. Over the past few years they have branched out, offering their in-house products to businesses.
Today, Alibaba dominates cloud computing in China with a 43% market share. Under Jack Ma, Alibaba made cloud computing a key priority, and CEO Daniel Zhang plans to make cloud computing technologies an even bigger part of Alibaba’s corporate focus over the next couple of years (for more information see Alibaba’s company profile).
Tencent’s cloud business is the second largest in China, with an 11% market share, according to industry researcher IDC. The company entered the ‘cloud-game’ relatively late, and recently announced to spur its push in cloud computing by investing billions of dollars. This move can be seen as part of its overall strategy to shift focus from its consumer-faced business to the industrial internet. Its cloud-computing business should cater to industries such as retail, mobility, healthcare, and education.

Alibaba and Tencent are members of the National AI Team

Starting in 2017, the Chinese government recruited Alibaba, Tencent, Baidu and iFlyTek to lead key projects in the development of next-generation AI technologies. Alibaba’s cloud computing division was tasked with a smart city project to improve urban life (see Smart Habitat layer for more details), while Tencent has been designated to become a leader in AI-assisted medical diagnosis.
Government endorsement helped Tencent to launch its AI Medical Innovation System, an AI-powered diagnostic medical imaging service. The technology currently has accuracy rates of over 90% for preliminary diagnoses of esophageal cancer, 95% for lung sarcoidosis, and 97% for diabetic retinopathy. Several of Tencent’s AI departments, such as the AI Lab and Tencent Youtu Lab, collaborated to develop the image recognition, using the over 1 billion images on the company’s social network. After the success in healthcare, Tencent is looking to apply its AI knowledge to other applications, such as transportation solutions, security, and protection, as well as voice recognition.

In this episode of the ChinaEconTalk podcast, China expert Jeff Ding of the Future of Humanity Institute discusses the detour Tencent is making from the national champion designation [12:18-13:35]:

Alibaba and Tencent are working on the city of the future…

ET City Brain
The Chinese government designated Alibaba with the task of applying innovative technology to improve urban life. This resonated in Alibaba’s cloud-powered and AI-driven urban project “ET City Brain,” which aims to use AI to optimize city-services in real-time. One of Alibaba’s first pilots focused on reducing traffic congestion in Hangzhou. The video below shows how innovations within several layers of the Stack (think of Cloud Computing, Facial Recognition, and AI) are merged to improve traffic speed up to 11%.

PATH
A joint effort in the smart city area is PATH (Ping An, Alibaba, Tencent, Huawei), a smart city initiative in which these four Chinese tech giants apply their core technologies and an investment of 50M RMB in order to propel China into the global smart cities race (and of course to counter some major problems such as air pollution and congestion).

…but rural areas are also a key priority for Alibaba and Tencent

While smart digital applications are often first rolled out in #tier 1 or 2 cities, both Alibaba and Tencent are currently working on a Rural Strategy. Especially Alibaba sees tier 3, 4 and 5 cities and rural areas as an important new addressable market.
Striking examples are:

•  Tencent-backed WeDoctor and Alibaba’s Good Doctor are making healthcare more accessible for patients in tier 3 and 4 cities.
•  Alibaba invested 716 million USD in Huitongda Network, a platform that offers a variety of business models to help offline stores sell goods via e-commerce offerings, and also help online retailers sell directly to rural residents.
•  Alibaba launched Rural Taobao in 2014, allowing rural residents to buy and sell items online through the company’s Taobao online marketplace. Since its creation, Rural Taobao has expanded steadily, growing to cover 29 provinces, more than 700 counties, and over 30,000 villages.
•  Juhuasuan is Alibaba’s group-buying and flash-sale platform and will be repositioned as an online marketplace for consumers in tier-4, tier-5 cities and rural areas.

“China is experiencing an ongoing consumption upgrade as people look for different ways to enhance their lifestyle. (…) We are now seeing more and more consumers in China’s less-developed regions becoming sophisticated shoppers. They are demanding the same high-quality products as those in top-tier cities.”

– Jiang Fan, President of Tmall and Taobao

Tencent and Alibaba aim for a friction-free consumer interaction through voice

Both Alibaba and Tencent are investing in new consumer interfaces. For example, they are discovering the power of voice as an interface, and more specifically the smart speaker;

Alibaba’s voice assistant is called Tmall Genie. The device is on the market as a regular speaker since 2017 but is also available as a mirror (Tmall Genie Queen) as a device in connected cars (Tmall Genie Auto), and with a built-in monitor (Tmall Genie Family).

The Voice Assistant will become an increasingly important player in our life. I believe that in the coming decade, it will be connected with more devices and be the point of connection for different scenarios in our life, using voice commands to control our homes, vehicles and our personal devices.”

– Miffy CHEN, General Manager, Alibaba AI Labs

Two years after Alibaba, Tencent launched its smart speaker Xiaowei. The launch of Xiaowei is seen as a move of Tencent into diversifying its products and services into more business and industries (such as the B2B and IoT market). Besides, Xiaowei (in English ‘WeChat italking’) will link WeChat users with Tencent’s services available through QQ and WeChat.

Tencent and Alibaba are investing in facial recognition technology

Based on the number of facial recognition patents, Tencent is more active in the field of face recognition than Alibaba. Nevertheless, both companies have already implemented facial recognition in real-life situations.
Tencent is working closely with government in implementing facial recognition. For example, some provinces are issuing electronic identification cards for their citizens using WeChat’s facial recognition technology. The mobile IDs can be used for authentication instead of carrying physical ID cards – mandatory for citizens at all times in China – for travel booking, real name registration at internet cafés, and other security checks. Furthermore, amid tighter scrutiny by the Chinese government, Tencent uses facial recognition to detect minors in relation to concerns that excessive video gaming is damaging public health.

In 2017, Alipay unveiled its facial recognition payment service ‘Smile to Pay.’ The company says that as facial recognition technology takes the place of QR codes, “paying by smiling” will most likely experience explosive growth over the next three years. Statistics from Alibaba during 2018’s shopping festival around singles day also suggest that payments through the face and fingerprint scans now make up 60% of all transactions.

Alibaba and Tencent are developing their own social credit systems

The best-known private system is Sesame Credit, developed by Ant Financial, an affiliate of Alibaba. Sesame Credit is a scoring system that generates individual credit scores for consumers by tapping into Alibaba Group and Ant Financial’s vast online ecosystem and other personal credit information sources. Sesame Scores, which range from 350 to 950 points, are calculated based on five factors – credit history, behavioral preference, fulfillment capability, personal attributes and social network – and are indicators of the users’ creditworthiness. Although the system’s focus is on creditworthiness, a low score can have an impact beyond loans (e.g. being banned from certain hotels) and a government blacklist has also been integrated. At the same time, a high score gives members the possibility to relax in special lounges at China’s train stations or to use bike sharing platforms HelloBike and Ofo deposit free.

Listen to this NPR podcast on the rollout of a Chinese Social Credit System and the role of Alibaba in it:

Tencent is also testing a credit scoring feature for WeChat Pay. Similar to Alibaba’s Sesame Credit, its score is calculated based on WeChat Pay’s pool of data, particularly on personal consumption behaviour. According to Tencent, the purpose is to “provide services that make people’s lives simpler and more convenient.” Users with high scores will be rewarded with perks such as waiving of deposits for rental services and hotels, and paying for services and goods after delivery.

Tencent and Alibaba contirubte to the State’s innovation goals

Although Tencent and Alibaba are originally consumer-focused companies, they are expanding their businesses to the ‘industrial internet’, which involves the broader adoption of advanced consumer and industrial applications that take advantage of next-generation technologies for business purposes.

For instance, Tencent is teaming up with Huawei Technologies, a Chinese multinational technology company that provides telecommunications equipment and sells consumer electronics, to accelerate innovation in core technologies, such as AI and cloud computing.

Meanwhile, last year Alibaba’s CEO Jack Ma called for Chinese traditional manufacturers to fully embrace what he called the “New Manufacturing” model. New Manufacturing involves a transformation of traditional manufacturing industry by integrating technology capabilities in the internet, data, AI, cloud computing and IOT. “Proposing the New Manufacturing model is not because Alibaba plans to enter the manufacturing industry, but rather to help manufacturing companies to innovate and upgrade,” Ma said during the 2018 Cloud Computing Conference in Hangzhou. “During this shift, the current manufacturer-oriented industry will transition to a new era led by customers, where small and medium-sized enterprises can benefit the most.”’

Incubators
Furthermore, both Alibaba and Tencent invest heavily in startups and support emerging companies with incubator programs. Tencent’s WeStart for example operates innovation spaces where it offers start-ups office space to rent and incentives such as tax exemption for three years and favorably-priced access to Tencent’s products and infrastructure. Furthermore, the company assists start-ups to target government-backed support programs. Meanwhile, Alibaba’s Cloud division teamed up with the U.S. workspace operator WeWork to develop an incubation program for 20 foreign startups to enter China, and assist 30 Chinese companies to expand overseas.

Alibaba and Tencent investments in electric vehicles

Alibaba, Tencent and several other Chinese companies have joined efforts to meet China’s ambitions concerning green growth of the automotive industry. They have setup car-sharing services T3, which is powered by renewable energy, called T3.

Other examples of investments in the green future of this industry are Alibaba’s leading role in the 2.2B RMB funding round in Xiaopeng Motors, a Chinese electric car maker that aims to speed up the development of electric vehicles. Alibaba elaborates on this investment: “As a clean energy vehicle start-up, the investment in Xiaopeng Motors fits with Alibaba’s strategic focus in the automotive sector. Under our open-platform approach, we will continue to work with a range of automotive manufacturing partners to benefit Chinese consumers”.

Alipay and Wechat transformed China’s Digital payment landscape

China is a country where Visa and Mastercard are (still) banned, and it has an underdeveloped banking system. As a result, Chinese society remained largely cash-based for a long time. Nevertheless, when China started to manufacture cheap mobile phones, Alibaba and Tencent successfully set-up their own mobile payment solutions known as Alipay (by Alibaba) and WeChat Pay (by Tencent).

Users of these payment solutions link their bank cards to the wallet inside the app. Once linked, they are able to use the wallet as a debit card for direct payments in stores or for online purchases. Furthermore, users can transfer money from their bank account to create a balance on the wallet.

The digital solutions provided by Alibaba and Tencent made it extremely easy for consumers to pay with their mobile phone. In 2018, over 85% of purchases made in China were on mobile payment platforms.
In physical shops, merchants offer consumers the opportunity to pay with WeChat Pay and Alipay mostly with QR codes.

Alibaba and Tencent are SOE-investors

Established in the late nineties, with founders around 50 years old, Alibaba and Tencent are classic examples of companies that stem from the previous generation. Alibaba and Tencent realize though that today’s wave of entrepreneurs is bringing products and services that appeal to Generation Z, and this is the reason they are heavily investing in innovative startups within and beyond the Chinese border. Furthermore, to arm themselves against newcomers, Alibaba and Tencent are combining their strengths to secure their position (see section 1).

Alibaba and Tencent are SOE-investors

As a testing-ground of the mixed-ownership reform, Tencent and Alibaba have both invested in China Unicom, the country’s second-largest wireless telecom operator. These investments are financial, but are also intended to improve the services of state firms. For example, Alibaba and Unicom launched a cloud knowledge venture in order to meet demand from SOEs and governmental institutions in China for innovative technology solutions. Tencent and China Unicom are amongst other things, working on a network security platform.

Tencent’s hometown is a Special Economic Zone

Tencent’s hometown Shenzen was appointed one of the first Chinese area’s to be a SEZ. Tencent – founded in 1998 – witnessed the effects of the nomination: the share of high-tech industries in its total industrial output increased from less than 10% in 1990 to nearly 40% in 1998. Companies could make use of incentives such as access to quality infrastructure, corporate income tax exemptions, exemptions from tariffs on high-tech equipment and special treatment for employees. Other companies that arose in this area were Huawei and ZTE ( global telecommunications equipment, networks and mobile devices company).

Alibaba and Tencent endorse the Communist Party

Tencent released a mobile game titled ‘Clap for Xi Jinping: An Awesome Speech’, in which players have 19 seconds to generate as many claps as possible for Xi.

In 2019, Alibaba reportedly developed the popular Communist Party propaganda app ‘Xuexi Qiangguo’ (in English: study to make China strong). Alibaba staff is said to be responsible for developing and maintaining the app that includes news, videos, livestream and community comments.

Confucian philosophy & Daoism underlie Alibaba’s corporate culture

Without the philosophy of Buddhism, you cannot do well when your business grows to a certain extent. If you do not know the philosophy of Daoism, you have no chance of winning during competitions. If you do not understand Confucian philosophy on the construction of organizational system, you have no chance to be sustainable when your company grows to a certain size.”

– Jack Ma, Founder and CEO Alibaba

Alibaba’s Founder and CEO is strongly influenced by China’s idea of the good life. He always carries a copy of the Tao Te Ching, the foundational text of Taoist philosophy, is a big fan of Tai Chi, and has held meetings with the senior executive team of the company in a temple. Under the eyes of Buddha, the focus would naturally be how to help others, to help ever more people.
Furthermore, Ma actively spreads the Taoist way of thinking among company employees. In the early days, all of them had a Kung Fu nickname (Kung Fu and Taoism are closely linked), Jack Ma’s being “Feng Qingyang”, which refers to an “unpredictable and aggressive” swordsman.
According to Brian Wong, Alibaba’s vice president of global initiatives, an understanding of the principles behind the philosophies do help in having a better grasp of why the Chinese tech market works the way it does. “China is much more about integrating as opposed to taking over or competing in the traditional sense,” Wong explains. “We want to create and integrate.”

Rare earhts are none of Tencent’s and Alibaba’s business

Rare earths are none of Tencent’s and Alibaba’s business. Apart from Alibaba’s semiconductors, both companies do not produce goods, and therefore they are not investing in, or owning, rare earths.

Tencent has dipped its toes in vertical drama

Tencent first dipped its toes into the vertical drama category in 2018, releasing short series like My Boyfriend-ish Sister and My Idiot Boyfriend. These entertainment shows are specifically designed for the mobile screen.
