The threat of climate change is looming before us. Sea level rise concerns over 410 million people at risk of losing their livelihoods. Coastal cities are choked with high-rise buildings and traffic-laden roads, consuming land insufficiently. Synthesizing these problems, architects across the world have proposed a potential answer - floating cities. A future of living on water seems like a radical shift from how people live, work, and play. Vernacular precedents prove otherwise, offering inspiration for what our cities could morph into. As world leaders discuss courses of action to tackle climate change at the COP27 climate summit in Egypt, ArchDaily dives into the concept of radical water-based settlements.
The 2022 United Nations Conference of the Parties, more commonly referred to as COP27, was held between November 6 and November 18, 2022, in Sharm El Sheikh, Egypt. The conference included more than 90 heads of state and an estimated 35,000 representatives, or delegates, from 190 countries. Aimed at encouraging and guiding countries to take effective action against climate change, the next edition of these conferences, COP28, is already scheduled from 30 November to 12 December 2023, in the United Arab Emirates. The CEO of the Abu Dhabi National Oil Co, an oil company chief who also oversees renewable energy efforts in the Emirates, was appointed to preside over the negotiations and talks, which led to a wave of criticism from environmental activists.
While approaching Wainscott Beach on Long Island’s South Fork in early December, one could see the most tangible aspect of offshore wind’s New York progress even before hearing the crash of waves: three pillars, each about as tall as the Statue of Liberty, jutting up from the ocean. They were the legs of the Jill, a liftboat from the Gulf of Mexico stationed about a third of a mile off the coast of Long Island’s South Fork.

The Italian city installed glass barriers around the 900-year-old church to keep the waters out. The decision was made after near-record flooding in December 2022, preventing a repeat of the November 2019 near-catastrophe that aged parts of the building “20 years in a day,” according to Basilica’s Procuratoria governing body. The temporary structure is fixed until the MOSE system fully works by the end of 2025, protecting the city of Venice, Italy, and the Venetian Lagoon from flooding.
At a time when the world is being forced to rapidly adapt to climate change, the landscape comes into focus as a subject and medium of more importance than ever. Nowhere is this better known than at the Weitzman School of Design at The University of Pennsylvania, where the landscape architecture department has been leading the field for almost a century.

A 2022 United Nations report claims that the negative impacts of the climate crisis are mounting much faster than scientists predicted less than a decade ago. Rising greenhouse-gas emissions could soon outstrip the ability of many communities to adapt, and the consequences will continue to hit the world’s most vulnerable populations. As climate scientist Maarten van Aalst suggests, “Any further delay in global action on adaptation and mitigation will miss a brief and rapidly closing window of opportunity to secure a livable and sustainable future for all.” The data is clear: to protect our planet, we need to prevent a 1.5°C rise in global temperatures this century. To do so, the world must achieve a 45% reduction in global carbon emissions from 2010 levels to 2030, to then reach a net-zero state by 2050. It is evident, however, that we are on track to miss this goal by a substantial amount. The clock is ticking, and every industry should act fast (and drastically) to even dream of greener cities.
Climate change has been one of the most pressing topics of this year, and for a good reason. Its effects are visible not only in natural habitats but also in urban environments. The construction industry has an important role to play in this dynamic. Throughout the year, events such as COP27 emphasized the importance of striving to achieve net carbon zero and the challenges faced by developing countries affected by increasingly devastating natural disasters. Possible directions for development include actions at varying stages and scales, from optimizing green spaces for urban heat control to employing local and innovative building materials to minimize the carbon footprint or passing laws that help create more sustainable urban and natural environments.
This article represents a roundup of articles published on ArchDaily during the course of 2022 with themes related to climate change and architecture’s potential to make a difference. It breaks down the topic into four main questions: What Are Cities Doing to Mitigate Urban Heat? How to Tackle Rising Sea Levels? What Was COP27 and Why Does It Matter? Can Building Materials Play a Role in Achieving These Goals? The last section presents an overview of new legislation approved during 2022 as a way of understanding how state and local governments are imposing this need for change.
Cities concentrate opportunities and exchanges, culture and business, while, at the same time are a key contributor to climate change. They are highly complex organisms, with multiple actors involved, that bring to light underlying social interests and conflicts present in society. In 2007, the world's urban population surpassed the rural and this difference has been increasing ever since. According to the 2018 Revision of World Urbanization Prospects report, 55% of the world's current population lives in urban areas, rising to 68% by 2050. This will represent an increase of 2.5 billion people in urban areas, with almost 90% of this increase occurring in Asia and Africa. The Smart Sustainable Cities: Reconnaissance Study also points out that urban centers account for 67% of global energy demand, emit 70% of greenhouse gases and, on top of it all, buildings consume 40% of all energy worldwide. The prospect of a mostly urban world, along with the alarming onset of climate change, both raise challenges regarding living conditions in the coming decades and centuries, and all the implications that will accompany these changes.

Interior architects and designers have often claimed that a well-designed office space will translate into greater productivity, creativity and worker satisfaction –yet the impact is greater than most tend to imagine. Recent studies suggest that good design positively impacts company culture, fosters a sense of community and creates a healthy, happy and motivating environment. In fact, it directly influences the recruitment and retention of talent: “workplace design significantly increases the attractiveness of employers to potential candidates.” Proper lighting, a flexible layout and biophilic features are all important factors to consider during the planning stage. But to fully address user comfort and well-being, these must be combined with excellent furniture design. After all, integrating high-quality ergonomic pieces is a simple way to boost mood and enhance functionality and aesthetics when creating or redecorating the workspace.
A few days ago, the world gathered at Sharm El Sheik, Egypt, for its annual climate change summit: COP27. Like the rest of Africa, Nigeria is represented by its retinue of bureaucrats, climate advocates, and other interest groups. Since the last meeting in Scotland (COP26), Nigeria signed the Climate Change Act into law, setting a target of attaining net-zero greenhouse gas emissions between 2050 and 2070. In the interim, Nigeria has developed an ambitious energy plan that would see it transition from fossil fuels to renewable energy, using its vast reserve of natural gas as a hedge. The country is at the forefront of the African Carbon Markets Initiative and plans to raise at least $500 million from carbon crediting trading to offset emitted carbon.

“Superstorm Sandy in 2012 was a wake-up call for NYC and made the city realize it needed to better prepare for climate change,” said Adrian Smith, FASLA, vice president at ASLA and team leader of Staten Island capital projects with NYC Parks. Due to storm surges from Sandy, “several people in Staten Island perished, and millions in property damage were sustained.”
On the 10th anniversary of Sandy, Smith, along with Pippa Brashear, ASLA, principal at SCAPE, and Donna Walcavage, FASLA, principal at Stantec, explained how designing with nature can lead to more resilient shoreline communities. During Climate Week NYC, they walked an online crowd of hundreds through two interconnected projects on the southwestern end of the island: Living Breakwaters and its companion on land — the Tottenville Shoreline Protection Project.
Stefano Boeri Architetti presented a new design for the Vertical Forest towers during COP27 in Sharm El-Sheikh, Egypt. The prototype would be in Dubai, the most populous city in the United Arab Emirates (UAE), and the next host of COP28 in 2023. The ambitious project would represent the first Vertical Forest prototype for the MENA (Middle East and North Africa), and it is the latest in an extended list of greenery-covered buildings by Boeri Architetti, including the Bosco Verticale in Milan, the Easyhome Huanggang in China, and a prototype of the First Dutch Vertical Forest.
In a presentation at the Buildings Pavilion Auditorium during COP27, the UN Climate Change Conference in Sharm El-Sheikh, Egypt, Skidmore, Owings & Merrill (SOM) presented the Urban Sequoia NOW concept. The proposal, developed by an interdisciplinary team at SOM, represents a design that can sequester carbon from the atmosphere throughout its lifecycle. The design can be implemented with today’s technologies. This represents SOM’s concept of going beyond net zero carbon by combining multiple strategies: reducing embodied carbon, generating energy, absorbing carbon, and increasing the typical 60-year lifespan of the building.
Starting on November 6, world leaders are gathering in Sharm el Sheikh, Egypt, for COP27. The name stands for the 27th conference of parties, an almost annual event started under the 1992 UN framework convention on climate change (UNFCCC). The purpose of these conferences is to ensure that counties around the world are committed to taking action to avoid dangerous climate change and find ways to reduce greenhouse gas emissions globally in an equitable way. The effectiveness of these meetings varied throughout the years, with some successful initiatives, like the 2015 Paris Agreement, a legally binding international treaty adopted by 196 Parties with the goal of limiting global warming below 2, preferably 1.5 degrees Celsius, compared to pre-industrial levels.

The building industry is one of the biggest generators of carbon emissions, with some estimates suggesting that 38% percent of all CO2 emissions are linked to this field. As a response to the current crisis, architects, designers, and researchers are taking measures to reduce their carbon footprint during and after construction. Many initiatives and research teams are looking at building materials to find low-carbon solutions and reduce the impact of building materials during production.
One of the most prominent fields of research is concerned with biofacture, the type of process that involves using biological organisms to manufacture materials. By understanding the abilities of organisms such as algae of fungi, alternatives to widely used materials can become carbon neutral or even carbon negative. Other initiatives are researching novel ways to use untapped, yet readily available resources such as desert sand, soil, or waste from demolitions.
While the United Nations has been continuously urging architects, engineers, and city shapers to put the 2030 agenda and the SDGs into action, and the IPCC report revealed intensifying climate change, sparking widespread discussion over insufficient action, the 83rd ongoing session of The United Nations Economic Commission for Europe - UNECE Committee on Urban Development, Housing and Land Management taking place in San Marino, has just issued a special declaration on “how to build better, safer, more inclusive, and resilient" cities, ahead of COP27. This set of “Principles for Sustainable and Inclusive Urban Design and Architecture”, or the San Marino declaration has gathered the signatures of Norman Foster and Stefano Boeri.
The first Monday of October of every year marks World Architecture Day and World Habitat Day. Celebrated simultaneously, they both seek to shed light on the built environment and its challenges, taking on a different theme with each new edition. This year, through its World Architecture Day, the UIA is focusing on “Architecture for well-being”, in line with the designation of 2022 as the UIA Year of Design for Health in buildings and cities. In parallel, the UN’s World Habitat Day, is centered on “Mind the Gap. Leave No One and Place Behind”, looking at the problem of growing inequality and challenges in cities and human settlements, due to the triple ‘C’ crises – COVID-19, climate and conflict.
Introducing Urban October, 31 days to promote a better urban future, World Architecture Day and World Habitat Day push forward the debates on urban sustainability. Joining the conversation every year, ArchDaily takes part in this occasion by promoting content that tackles the main objectives of this day, raising awareness, presenting solutions, engaging the international community, and “empowering everyone who makes architecture happen to create a better quality of life”.
It’s About Time, the 10th edition of the RotterdamArchitecture Biennale, is a seven-week-long manifestation showing realistic courses toward a livable future at a time when the consequences of climate change are becoming increasingly apparent. Half a century ago, the consequences of climate change were predicted in The Limits of Growth report from 1972. This outlines the possible consequences of an exponential increase in population, agricultural production, and resource extraction. The report is viewed by many as the beginning of environmental awareness. The Rotterdam Architecture Biennale aims to bring these changes into perspective by looking both at the past and the possible future.
