Sustainable Architecture: The Latest Architecture and News

Charles Darwin's theory of natural selection sought to explain the origin and survival of species on the planet. In short, it points out that the fittest organism survives and can reproduce itself, perpetuating useful variations for each species in a given place. Adaptation is, therefore, a characteristic that favors the survival of individuals in a context. In the construction world, we could draw some parallels. Could adaptation be an important quality to increase the useful life and efficiency of a building over time, considering the changes and demands of society, as well as technologies and lifestyles?

The Zero Carbon policy is intended to create a kind of ecological balance to neutralize greenhouse gas emissions. Several studies report that the construction sector is one of the main responsible for the unbalance in which we find ourselves today, after all, it consumes natural resources on a gigantic scale and still builds buildings that do not collaborate with the maintenance of the environment. Therefore, searching for paths towards a carbon neutral architecture has become fundamental and one of them is learning from past masters, such as the Brazilian architect João Filgueiras Lima, known as Lelé.

With the magnitude and urgency of the immediate Covid-19 crisis worldwide, efforts have been concentrated on saving lives, rather than focusing on concerns related to the road to Net-zero carbon. Net Zero carbon in regards to construction is defined as when the amount of carbon emissions associated with the construction of a building and its completion is zero. A zero-energy building will have an overall zero net energy consumption; the total amount of energy used by the building annually is equal to the amount of renewable energy generated on-site.

As the climate emergency presents itself as a severe and existential threat, it is crucial that the road to net-zero carbon is resumed large-scale in both an architectural and commercial sense. Around the globe, efforts have been renewed in an attempt to tackle the almost inconceivable. According to the 2019 global status report for buildings and construction, the buildings and construction sector accounted for 36% of final energy use and process-related carbon emissions in 2018. Although carbon emissions were temporarily reduced during the peak of the pandemic, they are set to swiftly return to previous figures.

"I Draw on Paper, but I Prefer to Draw on the Ground". This phrase caught my eye during Diébédo Francis Kéré's speech at the AAICO (Architecture and Art International Congress), which took place in Porto, Portugal from September 3 to 8, 2018. After being introduced by none other than Eduardo Souto de Moura, Kéré began his speech with the simplicity and humility that guides his work. His best-known works were built in remote places, where materials are scarce and the workforce is of the residents themselves, using local resources and techniques.

The tech industry in Japan has continued to serve as a pivotal driving force in Japan, with the whole country being well known for its technological innovations in various industries. As of late, most industries and companies have begun to shift their focus to the topic of sustainable development, with the inclusion of using these very technologies to work towards zero energy goals.

In April 2014, the Japanese government approved an energy policy to encourage Zero Net Energy Houses (ZEH) to become the standard for new house construction by 2030. Zero energy housing is designed to consume as much energy as it can create using renewable energy on-site.

When talking about energy efficiency in buildings, it is inevitable to mention thermal insulation. We rarely see it in a finished building and, even in the technical drawings, the insulating layer appears as a thin hatch. But this is an element that is of vital importance, as it acts as a barrier to the flow of heat, hindering the exchange of energy between the interior and the exterior, reducing the amount of heat that escapes in winter and the thermal energy that enters in the summer. In a building with good thermal insulation, there is less need for heating to keep the house at a pleasant temperature, also reducing its carbon footprint. Currently, there are many countries that require a minimum level of thermal insulation for buildings, with increasingly strict parameters. But how should this issue be dealt with in the near future, with the worrying climate crisis forecast?

Singapore as of late is continually building its reputation as a City in Nature, with Singaporean design long having a strong consciousness to acknowledge that green spaces matter. Urban planners and architects alike have taken a conscientious decision to weave in nature throughout the city as it continues to uproot new buildings and developments, incorporating the implementation of plant life in any form, whether it be through green roofs, cascading vertical gardens, or verdant walls.

This article will explore the pioneering actions taking place in Singapore to create a more biodiverse city and nation, and how this provides a view of how other major cities can adopt similar initiatives over the next decade to provide a blueprint for the future.

Taiwan proposes that architecture can transform a place, and to represent this idea, the work of Sheng-Yuan Huang and his practice, Fieldoffice, were chosen for the Taiwan Exhibition at La Biennale di Venezia in 2018, entitled Living with Sky, Water, and Mountain: Making Places in Yilan. Sheng-Yuan and Fieldoffice demonstrated that the notion of making places is more than building a physical space, but is equally about establishing a linkage between people, as well as people and their environment.

Alessandro Martinelli explores Sheng-Yuan and his colleagues at Fieldoffice as the avant-garde of a new architectural movement in his book, The City Beyond Architecture, which seeks to produce a new form of collective living through the lens of design and culture, touching on what the design culture of the majority of future urbanization could become. In the following, we will discuss Shen-Yuang's impact on Taiwanese architecture as he spearheaded the call to integrate and imagine public spaces that inhabited the capacity to structure a particular landscape to provide both social spaces and a sense of identity to its occupants.

The dawn of the Anthropocene has thrown the idea of adaptive reuse into the limelight: effectively the pinnacle of urban regeneration and revitalization. It utilizes the presence of existing buildings with historic and cultural value and re-purposes them to be functional. Essentially a form of architectural salvage; a sustainable and viable means of rebuilding.

Recent events such as the pandemic has highlighted inequalities in our cityscape, the inadequate segments in a state of disuse and disrepair. Adaptive reuse can replenish these areas and create new cultural hotspots, encouraging activity and creating vibrant and healthy mixed-use environments.

Below is a diverse selection of cultural hotspots using Adaptive Reuse

Arup reveals the competition-winning design for a 230m tall net-zero commercial tower in Hong Kong that embodies the city's aspirations to reach carbon neutrality by 2050. Taikoo Green Ribbon blends technology and nature to create an urban ecosystem sustaining a new generation of workplaces. Featuring a façade of curved PVs, hanging gardens, algae walls and various renewable energy sources, the project is a high-performance building slated to achieve carbon neutrality in less than a decade after construction.

Today, drywall and gypsum-based systems are currently present in almost all architectural works. These allow you to coat buildings with products that combine, among other attributes, construction ease, fire safety and the possibility of recycling, both in historic structures or completely new constructions. Since 1998, Saint-Gobain - one of the largest distributors of these types of systems - has awarded the projects that best apply them in their solutions, dividing them into 6 categories (Ceilings, Plaster, Plasterboard, Innovation & Sustainability, Residential, and Non-Residential). The submitted projects are meant to demonstrate how the architects managed to ingeniously unite the company's products with innovative solutions to overcome each of the difficulties that the works or contexts impose.

In its 12th edition, participants came from 30 different countries and showcased 74 projects. See the 14 awardees below:

Kiribati has a population of around 110,000 people and its economy is centered on fishing and agriculture. Comprised of 33 islands in the Central Pacific, its highest point is only 81 meters above sea level, which makes it potentially the first country that could disappear completely due to global warming and the consequent rise in sea levels. The climate crisis has been a hotly debated topic in recent years and terms such as carbon footprint, greenhouse effect, atmospheric aerosols, and many others, are already staples in our vocabulary. Another widely spoken term is “net zero”, or net zero emission, used as a goal for buildings in different industries and countries. Basically, it means that the energy balance is zero.

At the Dutch Design Week, a house created entirely from bio-based materials aims to illustrate that circular design is not only feasible but a scaleable construction method for the future. Featuring 100 types of sustainable materials, The Exploded View Beyond Building is a concrete example of the possibilities of creating a circular living environment, bringing together substantial research into high-quality components fit for disassembly and modular design.

Researchers credit the Hanging Gardens of Babylon as the first examples of green roofs. Although there is no proof of its exact location and very little literature on the structure, the most accepted theory is that King Nebuchadnezzar II built a series of elevated, ascending terraces with varied species as a gift to his wife, who missed the forests and mountains of Persia, their local land. According to Wolf Schneider [1] the gardens were supported by brick vaults, and under them, there were shaded halls cooled by artificial irrigation of the gardens, with a much milder temperature than the outside, in the plains of Mesopotamia (present-day Iraq). Since then, examples of green roofs have appeared all over the world, from Rome to Scandinavia, in the most diverse climates and types.

Nevertheless, inserting plants on roofs is still viewed with suspicion by many, as they are thought to be costly and difficult to maintain. Others, however, argue that the high implementation costs are quickly offset with savings in air conditioning and especially that occupying the building's fifth façade with vegetation is, above all, a rational solution. In any case, the question remains as to how green roofs can really help with climate change.

The choice of Lacaton & Vassal to receive the 2021 Pritzker Prize was, above all, emblematic. Under the mantra “never demolish, never remove or replace, always add, transform and reuse”, the French duo built a career focused on renovating buildings, providing them with spatial quality, efficiency and new programs. Their approach contrasts with most of the architecture we are used to honoring: iconic, imposing and grandiose works. It also contrasts with the notion of the tabula rasa, of building and rebuilding from scratch, so well represented in Le Corbusier's Ville Radieuse, and which has fascinated architects and urban planners ever since.

Whether because of the sustainability demands currently in vogue, or simply because there are already enough buildings around the world, the task of rehabilitating spaces and buildings has been seen as an important driver of change. The focus is generally to center efforts on interior spaces, paying special attention to the environmental quality and comfort of the inhabitants, in addition to adapting the uses to contemporary demands. The main question revolves around how to update (and even automate) the buildings of the past to adapt to new needs for efficiency, sustainability and well-being.

Zero kilometer materials can be purchased locally, do not need to be transformed by large stages of industrial processing or toxic treatments and, at the end of their service life, they can be returned to the environment.

For example, wood from a nearby forest eliminates the need for long transfers, valuing local resources, and allowing architecture to lessen its environmental impact while committed to the landscape and context.

MVRDV has revealed the design of "De Oosterlingen", a series of seven sustainable residential buildings on Amsterdam’s Oostenburg Island. The proposed buildings are distributed in a 'barcode' composition, forming an apparent unified design but with an animated skyline and unique characteristics such as varying roof shapes and façades of wood, glass, recycled brick, and bio-based composite.
