The expression “a perfect storm” refers to an event (typically an unfortunate one) which is exacerbated due to a confluence of negative or unpredictable factors. It is widely used when describing meteorological phenomena, but can also be applied to other contexts, such as the economy. The analogy can also be used to describe the relationship between the climate crisis and the world’s dependence on concrete. As demonstrated in the Chatham House report, while cement (an essential element for concrete manufacturing) is extremely detrimental to the greenhouse effect and climate crisis –representing about 8% of global CO2 emissions–, its global production is nevertheless expected to increase over the next 30 years. It is said that this increase will stem from the demand for rapid urbanization in regions such as Southeast Asia and sub-Saharan Africa. At the same time, the last IPCC report warned that we only have 11 years to reduce emissions and prevent irreversible damage due to climate change. In other words, the cement industry is facing a significant expansion at a time when emissions need to fall rapidly – a perfect storm.

The primary function of architecture, and possibly the most important and basic, is to protect against the weather. Whereas our ancestors would stack tree trunks and animal skins to create rudimentary shelters against the sun and rain, the emergence of architecture took on impressive proportions, creating temples and captivating spaces that fulfill many other functions. The purpose of sheltering people from the outdoors, however, remains an important one and can turn an outdoor area into a functional and engaging space. With all the innovations that currently exist, there are also numerous improvements emerging for their mechanisms and functions.

The 17th edition of the “Architecture Student Contest” has come to an end, with the participation of over 220 universities from 32 countries. This year, the challenge was to transform a district located in Warsaw, Poland in order to revitalize an area located next to Warszawa Wschodnia (Warsaw East). The contest involved the design of a new student residence and housing, as well as a meeting and entertainment center in an old factory building that is classified as a historical heritage site. With the requirement of addressing the space’s performance as well as its architectural, environmental and social aspects, the contestants were tasked with a project that positively impacts its users and the planet, with low carbon emissions throughout its life cycle.

Wallpapers can be quite controversial. They can be typical of old-fashioned and antiquated homes, but at the same time, they can also add personality to otherwise dull spaces. One of the best parts of using these elements is that they can be quickly installed, and with relatively low costs. This also means that they aren’t very long-lasting, and can therefore be quickly discarded and replaced, making them transient decoration items. As Joanna Banham—a researcher on wallpapers—states, “Wallpaper is often regarded as the Cinderella of the Decorative Arts – the most ephemeral and least precious of the decorations produced for the home. Yet, the history of wallpaper is a long and fascinating subject that dates back to the 16th century and encompasses a huge range of beautiful patterns created both by anonymous hands and by some of the best-known designers of the 19th and 20th centuries.” Today we are seeing another wallpaper resurgence, with numerous options of materials, patterns, and colors, and several examples of architects who have used them creatively in their projects. In this article, we go through the history of wallpapers and some of the current alternatives on the market, by diving into the Architonic catalog.

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.

Façades don’t always have to be opaque. Whereas in the past the only options were heavy and raw–such as stone and brick–in recent years façades have adopted an increasingly lighter appearance, with innovative materials becoming the protagonists. These give the building a different look, delicate and transparent, while still maintaining privacy and thermal comfort. Examples of these include polycarbonate, translucent sheets, perforated tiles, glass and even metal chain links, which was the chosen material for a building in Montpellier, France.

The terms critical regionalism, popularized by theorist Kenneth Frampton, proposed an architecture that embraced global influences, albeit firmly rooted in its context. That is, an approach defined by climate, topography and tectonics as a form of resistance to the placidity of modern architecture and the ornamentation of postmodernism. Bringing familiar elements to a particular location can allow the building to be better accepted and incorporated into the local context. This was the case of the New Maitland Hospital, which incorporated a large brick panel next to the main façade, as a reference to the community’s traditional symbols.

In the face of increasingly alarming predictions regarding the climate crisis, just increasing the efficiency of buildings is no longer enough. Zero energy buildings – or, better yet, energy positive buildings – make it possible to mitigate the negative impacts of the construction industry, which is responsible for 40% of all greenhouse gas emissions. These are buildings capable of producing more energy than they consume through the use of renewable sources. To reach this ambitious goal, it is necessary to follow three main steps:

There are many myths and misunderstandings around sustainability in construction. First, the belief that what is sustainable must inherently be technological, complicated or out of reach. Or that the products will necessarily be more expensive, will be made of recycled materials or will not be so aesthetically pleasing. When it comes to material specification, there is often confusion. Is steel more sustainable than bamboo? Would it be better to use a material that is said to be sustainable, but which goes through numerous industrial processes, or one with a low level of processing? The answer is not so simple, and there are various comparison mechanisms to help guide us. But this is an important consideration to make, as one of the main ways the construction industry can help reduce its carbon footprint is to select materials with the lowest general contribution to emissions and environmental impact. Natural slate, which can be used for roofing and facades, is a great example of this. 

As humanity becomes aware of its impact on the environment, it has also sought ways to reverse some of the harm caused to fauna and flora, especially in cities. Our way of living, consumption and construction has caused severe damage to nature. In fact, according to a study from the Weizmann Institute of Science, we are at a point of inflection where the mass of all man-made materials is equal to the planet’s biomass, and it should double by 2040. But not necessarily everything we build should have a negative impact. “The Tidal Stool” project is an example of this – part of a comprehensive revitalization project in Kuk Po Village in Shau Tau Kok in Hong Kong, which brings together two different ecologies, the anthropocentric and natural environment.
