Chinese temples have stood for centuries, battered by wind and earthquakes, without a crack or timber out of place. They employ an ancient technique called “bracket set construction” that requires no nails or metal parts to connect wooden structural elements. Scandinavian stave churches are nearly as durable. Unsurprisingly, there are plenty of trees in Sweden and all over China.

So what is with the hype about innovation in “mass timber” construction over the past few years? As Boyce Thompson argues in his thoughtful new book, Innovations in Mass Timber: Sequestering Carbon with Style in Commercial Buildings (Schiffer Publishing), this will be the next big thing in “green” tech for architects feeling guilty about their costly titanium skins and outsized carbon footprints. The color photos show some impressive buildings in places where the wood industry has always been healthy, such as the Pacific Northwest and Scandinavia. The Japanese build log cabins with imported material that might as well be gold.

UNStudio, in collaboration with local partner HYP Architects, has won the competition for the design of the Kyklos building in Luxembourg. The project is part of Beval, a large-scale redevelopment initiative aiming to transform a former industrial site into an urban center complete with a university and technological center, in addition to residential, office, and retail spaces. When designing the Kyklos building, which will occupy a central position in the district's main square, the architects set out to find solutions to create the smallest carbon footprint for both operational and embedded metrics.

A simple walk in the park will relax even the most tightly wound individual. But what about the places where people spend far more of their time, such as schools, office buildings, and hospitals? What role can design play in incorporating nature into those environments? And at what additional cost? Bill Browning has published a book—The Economics of Biophilia: Why Designing With Nature in Mind Makes Financial Sense, 2nd Edition (written with Catie Ryan and Dakota Walker)—arguing that the cost of bringing nature into building projects isn’t prohibitive but additive. An environmental strategist with a long history in green building, Browning is one of the founding partners (with architects Bob Fox and Rick Cook) of the sustainable design consultancy Terrapin Bright Green. Recently I talked with Browning about biophilic design—and, because he was a founding member of the U.S. Green Building Council’s board of directors, about the strengths and shortcomings of the LEED rating system.

As we understand it today, the sustainable architecture movement began to take shape at the end of the 20^th century. Essentially, it responds to growing concerns about environmental degradation, energy consumption, and resource scarcity. In this global discourse on sustainable architecture, wood has long been celebrated as a symbol of environmental consciousness and decarbonization. As one of the most widespread building materials, it has gained popularity with the rise of this movement. This is because trees absorb carbon dioxide during their growth, which stays in the wood during its construction use, keeping it out of the atmosphere.

The window for solving climate change is narrowing; any solution must include embodied carbon. The Sixth Assessment Report published by the IPCC (Intergovernmental Panel on Climate Change) concludes that the world can emit just 500 gigatonnes more of carbon dioxide, starting in January 2020, if we want a 50 percent chance of staying below 1.5 degrees. In 2021 alone, the world emitted about 36.3 gigatonnes of carbon, the highest amount ever recorded. We’re on track to blow through our carbon budget in the next several years. To quote the IPCC directly: “The choices and actions implemented in this decade will have impacts now and for thousands of years (high confidence).”

Refurbishment and adaptive reuse have been at the forefront of architectural discourse in recent years. This demonstrates that the profession is becoming increasingly aware of its impact on the environment and the opportunities presented by reusing what has already been built. Architecture 2030 has recently launched CARE, or Carbon Avoided Retrofit Estimator, a new digital tool that enables designers, owners, and communities to quantify the carbon benefits of adaptive reuse. By entering a streamlined set of project information, such as energy targets and potential building interventions, users can quickly estimate both operational carbon emissions generated by the use of the building and embodied carbon emissions, which are tied to the building materials employed.

Carbon footprint, circularity and environmental sustainability are terms that are increasingly present in many professional fields, but what do they mean? How do they relate to architecture and the built environment? We spoke with civil, environmental and sanitary engineer Lucas Rosse Caldas about these and other emerging architectural issues.

Lucas is a professor at the Graduate Program in Architecture at the Federal University of Rio de Janeiro and the Civil Engineering Program at the same institution. He participated in chapter 9 of the sixth report of the Intergovernmental Panel on Climate Change (IPCC) on buildings. He wrote several scientific and technical articles about architecture and sustainable construction.

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.

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.

Food pyramids are familiar to all of us. They are visual guides that show us the proportions of foods that we should supposedly eat on a daily basis, in order to stay healthy. Composed of a series of layers with different food types–such as grains, flour, fats, vegetables, and others–, at the base are the foods that should be consumed in larger quantities. Towards the top, each layer becomes successively smaller, indicating the foods that are meant to be ingested rarely. The pyramid can vary according to countries and cultures, but its main purpose is always to provide a guide for a balanced life. There are no prohibitions, but it does indicate some foods that should be consumed with caution because of their impacts on our health.

If we are what we eat, is it possible to also replicate this in the construction industry and our buildings? Using this same easy to understand visual language, the Royal Danish Academy Center for Industrialized Architecture (Cinark) developed the Construction Material Pyramid. The idea was to highlight the environmental impact of the most used construction materials, focusing on the analysis of the first three life phases: extraction of raw materials, transportation and manufacturing.

The growing consumer demand for transparency—especially around sustainability and environmental practices—has implications for industries from apparel to healthcare products. Mars Inc. recently released a cocoa sourcing map to tackle deforestation and increase accountability, and the Fashion Transparency Index pushes apparel companies to be more forthcoming about their social and environmental efforts.

Now it’s time for the building industry, characterized by a lack of information around the materials and practices used in construction and throughout a building’s lifecycle, to catch up. The cost of inaction is too high to ignore. That’s because buildings account for 39 percent of total global carbon emissions. Traditionally, most carbon reduction efforts in the building sector focus on operational carbon—a building’s everyday energy use, which accounts for roughly 28 percent of emissions. The remaining 11 percent comes from what is often ignored: embodied carbon.

All human activities affect the environment. Some are less impactful, some much, much more. According to the United Nations Environment Program (UNEP), the construction sector is responsible for up to 30% of all greenhouse gas emissions. Activities such as mining, processing, transportation, industrial operations, and the combination of chemical products result in the release of gases such as CO2, CH4, N2O, O3, halocarbons, and water vapor. When these gases are released into the atmosphere, they absorb a portion of the sun's rays and redistribute them in the form of radiation in the atmosphere, warming our planet. With a rampant amount of gas released daily, this layer thickens, which causes solar radiation to enter and and stay in the planet. Today, this 'layer' has become so thick that mankind is beginning to experience severe consequence, such as desertification, ice melting, water scarcity, and the intensification of storms, hurricanes, and floods, which has modified ecosystems and reduced biodiversity.

As architects, one of our biggest concerns should be the reduction of carbon emissions from the buildings we construct. Being able to measure, quantify, and rate this quality is a good way to start.

Martin C. Pedersen talks with Ron Rochon, managing partner at Miller Hull, about Carbon and the role of architectural firms in eliminating emissions. Discussing the EMissions Zero initiative, the current shortcomings of carbon offsets, and the way forward, the piece also questions the possibility of setting goals with the absence of an internationally, agreed-upon carbon cap.

In order to start integrating embodied carbon studies into projects to meet sustainability goals, it is important to consider many factors such as carbon (kgCO2e) values, and what typical ranges of values to be aware of when designing for embodied carbon reduction. This e-book presents an overview of how to start integrating embodied carbon studies in your projects.
