Not all projects seek a constant connection with the outside, at least not in their front façade. Despite not being a usual appearance, there are several reasons for creating an opaque façade: privacy, security, reduced energy consumption, and protection against inclement weather. More common in government, cultural or religious buildings, this solution is also found in some residential cases.
Sustainability needs to go further beyond inspiring speeches and promises, with visible, concrete actions. In order to see this change, it is essential for individuals, companies and governments to take responsibility and act in a sustainable manner in their daily lives and practices. By taking into account the environmental and social impacts of their decisions and seeking more conscious and responsible alternatives, they can take steps to ensure a sustainable future for the next generations. In the construction industry this is even more urgent. Responsible for a large amount of solid waste and greenhouse gas emissions, it is essential for this industry to adopt sustainable practices, such as recycling, to minimize environmental impacts.
However, even though product recycling processes have significantly advanced in recent years, there are still certain challenges associated with the use of recycled materials. This is due to a variety of factors, such as performance and durability, or even due to the difficulty of obtaining suitable raw materials. But there are also successful examples that show the possibilities of recycled materials.
Inherited from ancestral techniques, dealing with natural stone as a building material is, historically, linked more to the structure of a building than to the finishing stage. With the development of construction, natural stones as a structure were replaced by more efficient and cheaper systems, such as reinforced concrete or even metallic structures and structural masonry, opening space for the use of stones as finishes and coatings.
Versatility is the main characteristic of wire mesh. They can be used indoors, as ceilings and walls, but also outdoors, covering railings or wrapping entire buildings. In addition to its many possible uses, versatility is intrinsic to the material: Depending on the choice of warp and weft wires and the type of weave, the result is an individual mesh with a specific look and light effect, that can be further expanded with different materials or colored mesh surfaces. Another notable quality of the material is the safety it provides, either in guard rails on walkways, vehicle bridges with sidewalks, central atriums, elevated playgrounds, multi-storey parking lots, or internal or external stairways.
The façade is the only part of the building that can be seen from the outside and has the function of communicating a message derived from its design. It therefore deserves special attention in every detail. A façade that is well proportioned in terms of colours and materials, which facilitates the connection between the interior and the exterior, will generate an initial attraction for pedestrians, inviting them to enter.
From a small house clad in classic tiles, to big brands such as Apple or Louis Vuitton, façades are used as an architectural expression to give us a glimpse of the first elements that we will later find inside the premises. In interior design, the entrance hall of a home concentrates many clues as to what we will find next. The effect of this first impression would be even more positive if the façade included a design that leaves the user hungry for more.
As climate change continues to reach unprecedented levels, many are pointing towards enhancing circularity in the construction sector. Essentially, the circular economy aims to eliminate waste and the continual use of resources by repeatedly reusing, repairing or recycling materials. The cyclical approach is able to meet demand and minimize CO2 emissions by extending a product’s lifespan, which is especially important when dealing with limited resources. Unlike the traditional linear extractive method –where everything goes through an extremely contaminating process of 'take-make-waste'–, circularity keeps materials in use for as long as possible to extract maximum value. This, in turn, reduces pollution, regenerates natural systems and contributes to a healthier built environment, hence building economic, natural, and social capital.
Used by artisans across the globe for thousands of years, colored glass is one of the oldest art forms. Its origins date back as early as the 7th century, when stained windows began adorning churches, cathedrals and convents – often representing religious symbols and Biblical stories. These expanded to Islamic mosques and palaces during the 8th century, and by the Middle Ages could be found in countless churches across Europe. The intricate glass work reached maximum splendor in the monumental buildings of the Gothic period, resulting in giant, elaborate windows with extremely complex figures, patterns and geometries. However, gone are the days when this was reserved exclusively for prominent places of worship or ancient structures. Hand in hand with innovative production methods and new technologies, colored glass has made a comeback in contemporary architecture, enhancing countless buildings with its bold, lively hues.
Blending in with its urban context or standing out to draw attention, a façade tells a building’s story. It is an expressive medium through which we engage with architecture, defining first impressions and setting the tone for the interior by experimenting with transparency, movement, texture and color, among other aesthetic possibilities. Of course, the envelope also plays a crucial functional role, acting as a protective barrier against extreme weather conditions and directly impacting light transmittance, energy efficiency and acoustic comfort. Architects therefore face an important challenge: to achieve a balance between an attractive look and performance. To do so, it is pivotal to specify the right materials during the design stage.
When building near the sea, a project’s design strategy must pay special attention to the effects of marine corrosion. The salt content in the environment provokes a chemical and physical process which incites a material breakdown or degradation, compromising the durability of the building’s infrastructure.
As a response to the demands for ocean-side buildings, and the corresponding façade components that go along with them, air-lux has developed a system that aims to perform reliably in maritime conditions. By virtue of its corrosion-resistant materials, improved surface coatings, and technically optimized components, the system withstands marine climates and minimizes salt water damage.
The mystery of color intrigues us from a young age. Mixing paints to make new hues or watching sunbeams and crystals create rainbows becomes a fascinating part of our childhood long before we ever hear of chemistry and optics. As we grow, color continues to play a major role in how we experience the world, impacting mood, emotions, productivity and behavior. This explains why humans are naturally drawn to certain hues; it is hard-wired into their brains. There is a common perception, for example, that red, orange and yellow palettes create a feeling of warmth and cheerfulness, while browns, grays and blacks evoke sadness and melancholy. Of course, the same applies to design and the built environment, as together with texture, light and shadow, the spaces around us are defined by tones and nuances that shape what we see and how we feel. Hence, color ultimately transforms the way we perceive, feel and live architecture.
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.
Cladding systems have important functions in buildings. They can confer thermal insulation, protect internal spaces from the weather and–just as important–give the building a "face", improving its appearance and clearly identifying the element of design. "Cladding" refers to the components that are linked to the structure of a building to form non-structural external surfaces. While in the past wooden cladding was the only option, there are currently multiple possibilities of materials, colors, weights, textures, anchoring systems, and many other variables available. Below, we outline some of the main materials used for façade cladding, and the projects that use them in a remarkable way:
PVC, as the synthetic material Polyvinyl Chloride is called, or Polyvinyl Chloride, is one of the most produced plastics in the world, reaching 40 million tons per year. Its application is quite varied and in construction it has found different branches, serving both as an input for infrastructure and for finishing.
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?
Following news of Edelburg Development's plans to completely remodel the modernist facade of Dytiachyi Svit (Kids’ World), one of Kyiv's most notable modernist buildings from the Soviet era, and replace it with an "unrecognizable" vibrant and contemporary design, members of the community and activists protested against the intervention, forcing all parties to agree on a design competition to restore the historical facade. Dmytro Aranchii Architects was selected as the winner of the competition, with a proposal that "traces the transition from the original building to the new one" in a minimalistic and recognizable stylization, preserving the original facade and complimenting it with a contemporary intervention.
From creating a new parking structure with an awe-inspiring aesthetic to retrofitting an existing building, architectural wire mesh provides versatility and durability which makes it unique from other design material options.
Façade is one of the most important factors in certain building types, that can completely transform the occupant experience and the energy performance of the building. The Whole Building Design Guide showcases that the facade can have up to 40% impact on the total energy use of the building. In addition to the energy use, the facades also significantly impact the occupant productivity withing a building and, of course, the appearance of the building. There are many factors that go into creating a high-performance façade. In this article, we outline the top 5 things a design team should consider.
J. Mayer H. has won a competition to design the new façade of Cologne Main Station on Breslauer Platz in Germany. The design proposal frames the sides of the rail station with an all-around façade that offers an innovative use of space by making the best of the site's circulation and natural resources. The intervention will feature rooftop landscaping with local flowers and greenery, rainwater collection, protection from rain, wind, and sunlight, and a visual emphasis on the station's points of access.
