Reimagining the future: Asia’s architects turn to heritage for sustainable solutions
Planners, designers, and developers around Asia are looking to the region’s past for inspiration as they attempt to reduce harmful carbon emissions
Lee Kuan Yew was once asked what was behind Singapore’s breakneck development and economic success in the second half of the 20th century. The citystate’s founding father responded simply: “Air-conditioning”.
One of his first acts upon becoming prime minister in 1959 was to equip all civil service buildings with air-conditioners (AC). According to Lee, it was one of “the signal inventions of history. It changed the nature of civilisation by making development possible in the tropics.”
Not only did its introduction transform how people in the tropics worked; it changed how— and where—they lived.
For centuries, buildings in Asia were designed to adapt to and manipulate the local climate. Deep overhanging roofs, for instance, provided shade and rainwater runoff, while high ceilings and tall windows enhanced air circulation. Louvred windows and adjustable shutters regulated light. Airflow and the use of natural materials like bamboo and timber, meanwhile, maintained cool interior temperatures.
But the widespread availability of air-conditioning and advancements in construction technology, coupled with the affordability of materials like reinforced concrete and steel frames, rendered these age-old practices virtually obsolete. Indeed, it is now difficult to imagine a home, office, shopping mall, or public transport system in Asia’s cosmopolitan areas without controlled temperatures.
And yet the use of AC units significantly contributes to greenhouse gas emissions. According to the US-based National Renewable Energy Laboratory, AC systems account for approximately 1,950 million tonnes of carbon dioxide released annually, representing nearly four percent of global greenhouse gas emissions. Moreover, the International Energy Agency estimates that the buildings and construction sector consumes 36 percent of global energy and is responsible for 39 percent of energy and process-related carbon dioxide emissions. Within the sector, manufacturing building materials such as steel, cement, and glass contribute to 11 percent of emissions, while building operations account for the rest. “Energy consumption makes up a significant portion of the operating cost in this region,” says Chris Marriott, chief executive at Savills Southeast Asia. “So measures to help such consumption will improve both the environment and help the bottom line. A good example would be airconditioning, which makes up around two-thirds of power used for buildings in Southeast Asia.”
It makes sense then why so many architects and urban planners in Asia are turning back the clocks in search of an antidote to the destruction wrought by contemporary construction methods. One of the region’s highest-profile advocates of passive design is Jason Pomeroy. The British, Singapore-based architect blends a deep understanding of local culture, cutting-edge green technology, and traditional building techniques to reduce carbon emissions in his designs.
“You can distil the lessons of a past culture to design for the present and then you can disseminate that for future generations. Ultimately, some of the best design ideas have already been done,” he says.
More than a decade ago, Pomeroy and his team launched Southeast Asia’s first zero-carbon prototype home, The Idea House, in Malaysia. Inspired by the country’s traditional kampung houses, the modular property is designed to optimise natural light and ventilation to generate sufficient energy to offset the occupants’ usage.
Pomeroy Studio went a step further when it unveiled Singapore’s first carbon-negative property. The B House, a standalone residence, also draws from the island’s design techniques associated with the island’s colonial black-and-white bungalows such as sweeping verandahs and shutters combined with green smart home technology, to produce more energy than it consumes.
“The concept revolves around reconnecting with nature,” Pomeroy explains. “It’s akin to Mr. and Mrs. Caveman sitting at the entrance of their cave. They discovered fire, allowing them to venture further inside to illuminate the space, keep warm, and cook. Throughout history, we have progressively retreated deeper into the cave.
“Now, it’s time to return to the entrance to embrace the outdoors and rediscover the fundamentals of natural light and ventilation to minimise our consumption.”

On a much grander scale, Mumbai’s authorities unveiled plans last year to achieve carbon neutrality by 2050, positioning the city two decades ahead of India’s national goal. This ambitious target makes Mumbai the first city in South Asia to set such a timeline, and its implementation is crucial for the city’s survival. A study conducted by the India Meteorological Society warns that if sea levels continue to rise at their current rate, nearly 40% of Mumbai could be submerged within the next 100 years.
Practitioners are evaluating how to effectively implement similar plans in other major metropolises throughout Asia. In 2021, C40 Cities, a global organisation comprising nearly 100 mayors from leading cities worldwide, joined forces with the local governments of Kuala Lumpur, Jakarta, and Quezon City. The Climate Action Implementation Programme, spanning from 2022 to 2025, aims to support these cities and their combined population of 15.5 million residents in becoming carbon-neutral by 2050.
“Cities are on the frontlines of the climate crisis, and highly vulnerable to the impacts of climate change. They are also where solutions lie and transformative actions are taken,” Milag San Jose-Ballesteros, C40’s regional director for East and Southeast Asia, and Oceania, says in a statement.
Following its radical development program in the 20th century, the Singaporean government has implemented similarly bold initiatives to tackle the climate crisis. It currently tops Knight Frank’s APAC Sustainably Led Cities Index, which measures the reduction in per-person carbon use over time; initiatives focused on combating climate change, expanding green spaces, and increasing the number of green-rated commercial buildings; and the level of urbanisation and population growth.
And while the island state may currently be the epicentre of the fight against the climate crisis in Asia, numerous stakeholders within the region’s real estate industry are actively contributing to sustainability efforts. Design firms, urban planners, and sustainably driven developers are all playing their part in adapting Asia’s built environment to meet the urgent needs of tomorrow.
Here, we present a handful of some of the most sustainable projects currently under construction in Asia.
LIMA Estate by Aboitiz InfraCapital Economic Estates
The expansive 800-hectare development in Batangas continues to make headlines. Not only is it the largest privately owned industrial estate in the country, but it has also recently achieved the distinction of being the first of its kind to receive a BERDE 5-Star Certification.
