Thermal comfort becomes very evident when it is not attended to. When thermal conditions are adequate in one location, our body is in balance with the environment allowing us to perform activities normally. On the other hand, when a space is too hot or too cold, we soon see changes in our mood and body. Dissatisfaction with the thermal environment occurs when the heat balance is unstable, that is when there are differences between the heat produced by the body and the heat that the body loses to the environment.
Architect and Urbanist graduated from the Federal University of Santa Catarina (UFSC). Master in Urban Planning, History and Architecture Program, also at UFSC, with research related to the theme of mobility and urban sprawl. Interested in projects of urban requalification, non-motorized transport and public spaces, among many other subjects. Has been collaborating in ArchDaily Brasil since 2012 and is currently Editor of Architecture Classics and Articles.
During the modern period, the buildings that used the traditional sloping roofs with tiles, draining the waters as quickly as possible, have begun to give way to the well-known 'waterproof flat roofs.' In spite of delivering a clean aesthetic to the project, allowing the use of the last slab as a space for living and contemplation, this solution can become a headache for its occupants if its execution and design are not careful. It is no accident that there have been infiltrations in famous modern buildings, such as the Vile Savoye or the Farnsworth House, designed by great masters of architecture. Currently, the civil construction industry has developed more sophisticated products and techniques that drastically reduce the chances of subsequent infiltration. However, we could say that waterproof flat slabs continue to be fragile points in buildings. The architects from Brasil Arquitetura have improved an inventive and very simple solution to avoid infiltrations in flat slabs, much used in the 70's by architects like Paulo Mendes da Rocha and Ruy Ohtake, filling them with vegetation.
As urban dwellers become more aware of the environmental impacts of food production and transportation, as well as the origin and security of what they consume, urban agriculture is bound to grow and attract public and political eyes. Bringing food production closer, in addition to being sustainable, is pedagogical. However, generally with small size and other restrictions, the concerns of growing food in cities differ somewhat from traditional farming.
Urban gardens can occupy a multitude of places and have varied scales - window sills and balconies, slabs and vacant lots, courtyards of schools, public parks and even unlikely places, such as subway tunnels. They can also be communitarian or private. Whatever the case, it is important to consider some variables:
As ingenious solutions for environments that require additional space and ventilation, articulated or accordion doors and windows operate by folding their leafs one over the other and onto the sides of the opening. They moving via upper and lower rails which can be embedded into masonry and allow separation and integration rooms while adding aesthetic value to the project.
This system generates a similar effect to that of a sliding door or window, but it differs in that all its leafs remain in the same plane when they are closed, giving a clean appearance to the façade.
Gottfried Böhm is a German architect who was awarded the Pritzker Prize in 1986. His father, Dominikus Böhm and his grandfather Alois Böhm were both architects, as well as three of his sons, among them, Peter Böhm. Few people know that he has two projects erected in Brazil, in Brusque and Blumenau - two cities highly influenced by German culture. Photographer Ronaldo Azambuja shared with us his series of photographs of the mother church Igreja Matriz São Luiz Gonzaga in Brusque. The text was written by Angelina Wittmann, architect, and researcher.
Glass is so present in our lives that it’s very difficult to think about the amount of work, experimentation and technologies behind each panel or glass object. It’s also impossible to separate innovations from modern architectural projects –from architects such as Mies Van der Rohe and Le Corbusier– from the advances of the glass industry.
We’re following the history of glass, from Mesopotamian artifacts to technological glasses, and we invite you to travel with us.
Many of us have already lived, are living, or will live in a shared student house - a good mix of cheap housing and intense socializing with friends and school mates. For a reasonable price, it is possible to have a single private room and share common spaces. In fact, not only university students are living this way nowadays. The concept of co-living is becoming more and more an attractive and effective solution.
A technological innovation is revolutionizing one of the oldest professions in the world. Augmented reality has just broken onto the scene and has already been transforming civil construction. The changes are seen not only in designing and modeling, but also in building. Augmented reality benefits the entire construction team: engineers, designers, architects, project managers and service providers.
Unlike virtual reality, which creates a totally new and independent environment of the real world, augmented reality includes virtual elements that interact with what already exists. It is thus possible to combine virtual architectural designs with the reality of the construction site, increasing efficiency and accuracy, reducing the occurrence of errors and saving time, money and resources.
"Acoustics" in architecture means improving sound in environments. Although it is a complex science, understanding the basics - and making efficient and effective decisions - is much easier than you might think. The first step is to understand that there are two technical categories used in acoustics: soundproofing and acoustical treatment. Soundproofing means "less noise" and treatment, "better sound".
Rammed earth constructions are not a novelty, on the contrary, some sections of the Great Wall of China were made using this technique. Relegated and replaced by modern methods of construction, the mud walls are currently re-emerging as an economic, sustainable solution, with low environmental impact. Even Joelle Eyeson, a young African entrepreneur, is betting that it may be the answer to the housing deficit in her region.
This is a rudimentary construction system in which earth is compressed into wooden boxes. The clay is horizontally placed in layers of 15 cm in height, and compacted with manual or pneumatic tools, to achieve its ideal density creating a resistant and durable structure.
Let's suppose you need a bookcase. Years ago, you would probably search the furniture stores or antique shops in your town. Today you are more likely to open dozens of tabs on your web browser to compare prices and models. But there is another option that is becoming increasingly popular: open source furniture.
It's simple; you download the design of a piece of furniture and send it to a CNC machine (a mill that cuts wood from a digital file). It’s more or less like sending a PDF to print. With the pieces cut, you just assemble it. We used a bookcase for example, but it could be a chair, a table, a cupboard, a bench. Opendesk, one of the current open source furniture platforms, brings together about 30 pieces of furniture available for download. There the user can download a project and cut the furniture in a FabLab or personal workshop, or use the site to connect with a joiner who makes the cuts.
Studies show that public investment in integrated and safe cycling networks promotes urban transformation, providing more humanity, health and quality of life in urban spaces. While cities in the Netherlands and the Nordic countries have already incorporated bicycles into daily life, with a significant portion of the population using the means of transport for daily commutes, much of the world is still seeking a model to reduce congestion and increase its use. According to the Institute for Transportation and Development Policy (ITDP), investing in non-motorized transport allows congestion reduction, improves air quality, physical and mental health of residents, and local trade and brand visibility, once that cyclists tend to pay more attention to local commerce and take up less space than cars.
But along the cycle lanes and cycle paths it is essential to provide suitable places so that bicycles can be parked at the end of the trails. While bike stands are enclosed spaces, usually with some kind of surveillance and additional infrastructure, paracycles are the structures that allow to securely support and lock the bike. They can integrate in the urban furniture of a city, next to benches, plates, lamps and informative totems.
Cardboard tubes are so commonplace that we may no longer even notice them. Yet they are everywhere: in a roll of toilet paper, in the packaging of the college diploma, in fireworks, and in the tissue and paper industries. And now, more and more, they can be found in unusual places, such as on the walls of houses and buildings. The material is part of modern life and is being produced for a multitude of industrial applications and consumer products. The vast majority are used as structural cores in winding operations. Immediately after manufacturing, paper, film or textiles are rolled directly onto cardboard tubes resulting in a stable roll that is easily stored and transported.
There are few things that fascinate us more than the sea. Its contemplation arouses a sense of peace, while its colors, textures, movements and amplitude provide a scientifically proven effect of relaxation in our nervous system. Above all, it makes us realize how small we are in the universe. It is not by chance that a house facing the sea is a dream of consumption for many, let alone with a pool right in front of it. Infinity pools play with this feeling of infinite sea and sky. Through a well-elaborated set of levels and plans, they create an optical illusion that leaves everyone speechless, making pool water appear as if merged with the horizon, overflowing at one or more edges. But before you plan your photo on Instagram with a glass of sparkling wine in your hand, let's take a look at how these pools are built.
This renovation project by Peter Ebner and friends ZT GmbH is about the history of a place and changing tastes and times. It is about not needing a large scale to radically improve the space around. It is about the beauty and character of the city with its reflected sparkling life, gloomy evening sky, raindrops and lights of passing cars. It is about people who are mostly in a hurry, but who still sometimes stop for a few seconds to take note of a special, glittering room.
Perhaps the most renowned 'skylight' ever built is the Pantheon of Rome commissioned by Marco Vipsanius Agrippa during the reign of Emperor Augustus (27 BC-14 AD) and rebuilt by Hadrian (117-118) around 126 AD. At the highest point of its dome (in this case, the oculus) the sunlight shines, casting its beams over the various statues of planetary deities that occupy the niches on the walls. The light that enters the space symbolizes a cosmic, sacred dimension. In projects around the world, natural light continues to fulfill this scenic role, especially in religious projects.
It is characterized as zenithal illumination as that which comes from above, from the sky (zenith). Very useful for large spaces that can not be adequately lit by windows, skylights are a widely used device for providing a pleasant, diffuse light. Generally, care is taken to prevent direct entry of sunlight; the openings must be well designed so that they do not overheat the space of allow water infiltration. Below is a collection of projects that make good use of this technique.
The increasing use of air conditioning is causing many cities to hit record energy consumption levels during brutally hot summer months. In populous countries like India, China, Indonesia, Brazil, and Mexico, large urban centers function like ovens: buildings absorb heat that is re-released back into the environment, further increasing the local temperature. More heat outside means more air conditioning inside, which not only raises energy consumption, but also increases the levels of carbon dioxide in the atmosphere.
With this vicious cycle in mind, a paint was created to protect buildings and urban structures from excessive solar radiation, diminishing the effect of the urban heat island. The innovation came from the partnership of UNStudio, a Dutch architectural firm, and Monopol Color, a Swiss paint specialist. The dark-colored materials that are used to construct the buildings in our cities are one of the main causes of heat accumulation in urban areas. While darker materials absorb up to 95% of the sun’s rays and release them straight back into the atmosphere, this value can be reduced to 25% with a normal white surface. Now, with ‘The Coolest White’, it is possible to reduce absorption and emission to 12%.
When we think of energy from renewable sources, the first that probably come to mind are solar and wind. And decentralizing power generation is something that has inspired engineers and inventors from all over the world.
So what about turning the mechanical energy generated when people walk into electrical energy? It can be done thanks to technology developed by Laurence Kemball-Cook,founder of Pavegen. Using platforms inserted within sidewalks Pavegen converts steps into electric power (while also generating data and even rewards). But before you go out there feeling like Michael Jackson in Billie Jean, you should understand how this system works.
