Traditional building solutions tend to work well in their respective contexts, as they have withstood hundreds of years of testing and improvements, and use techniques and materials available locally. Although globalization and the democratization of access to technology have brought more comfort and new opportunities to humanity, it has also led to the homogenization of solutions in the construction sector and a dependence on global supply chains for construction materials and components. This has also caused a rupture in how knowledge is passed on to new generations and, eventually, the disappearance of traditions.
In particular, the topic of passive cooling solutions for buildings is currently having a resurgence, with an effort to recover ancient techniques used throughout history in locations that have always had to deal with hot climates. This is even more evident due to the high energy costs imposed by artificial cooling, the global warming scenario, and mainly because, among the projections of population growth, a significant portion of megacities will be located in the predominantly hot climates of Africa and Asia. When we think about the future, is it possible to be inspired by the past and apply ancient cooling techniques to contemporary buildings?
Walking down the streets of cities like Hanoi and Saigon in Vietnam, you might encounter houses with surprisingly narrow facades in contrast to the stacking of three to five floors, with windows for ventilation and natural light only on the front facade. These are the famous traditional Tube Houses. According to ancient popular culture, this type of housing emerged due to property taxes being based on the width of the facade, but the true reason is to optimize land use, allowing a larger number of plots in the same square.
However, this legacy is now being recreated in contemporary designs by Vietnamese architects. Old facades give way to innovative solutions featuring atriums for natural lighting and ventilation, courtyards and interior gardens, greenery incorporated into different environments, split-levels, etc., allowing for high-quality spaces. With that in mind, we have put together a selection of Tube Houses, together with their respective section drawings. Check out below:
During the first half of the 2nd century AD, one of the most important buildings in the history of Western architecture was erected in Rome: the Pantheon. Its main and most impressive feature is its coffered concrete dome, which ends in a perfectly round central opening. This oculus kicked off a series of later projects that noted the value of circular openings, which were replicated as glazed skylights and as compositional elements on facades. This eventually evolved, for example, into the detailed and colorful rose windows of the Gothic basilicas. In all its configurations, the oculus (meaning "eye" in Latin) holds symbolism that goes beyond that of a traditional window: its luminous projection gracefully marks the passage of time, solemnly highlighting an architectural space.
Using only natural light to document English cathedrals can turn into a logistical and technical challenge. However, Peter Marlow's photography has resulted in a remarkable series of iconic spiritual sites whose contemplative atmosphere is rarely accessible to others. Looking east with the camera towards the nave as the dawn light streamed through the main window opens a purist and mystical perspective to the time when these sacred structures were erected.

Daylight is core to realizing healthy and sustainable buildings, but its dynamic nature and the complex ways in which it interacts with its environment make it a difficult discipline to master. The new version of VELUX Daylight Visualizer makes climate-based daylight modeling more accessible than ever, empowering architects to make the best use of daylight anywhere in the world.
The motto of the Solar Decathlon Europe 21/22 was to convert and expand rather than to demolish and reconstruct. Recycling windows, using biodegradable materials for luminaires and connecting light with sensors represented just some innovative examples of the international university-level student competition in Wuppertal, Germany. For the first time, the competition presented an award for sustainable architectural lighting. This was a question of quality as much as quantity, and that applies equally to daylight and artificial light.
On August 27th, 1883, the volcano of Krakatoa in the Indonesian islands erupted. Ashes and rocks flew miles high. Barometers wobbled three and a half times as they recorded the atmospheric pressure wave circumnavigating the globe. The noise was heard across the Indian Ocean and Australia. And for years, small ash particles floated in the atmosphere, diffusing the sun’s light and scattering colors around the world.
Living in an urban environment is demanding. Busy and competitive lifestyles leave people numbed from the effects of stress. Individuals in urban areas are more prone to mental health issues and demonstrate a noticeable lack of personal connection. Rosy city lights and skyscrapers are thorned with rising stress levels, posing an essential question to architects - how do spaces affect wellbeing?
Whether it is a small balcony, access to green space or a private garden, the outdoor space has become a privilege for many, especially upon the dawn of the Covid-19 pandemic and the multiple lock down periods that followed. Green space in the city is constantly under threat, particularly since governments seek to increase housing densities in order to feed a growing demand for suburban development. As a result, the garden and access to green/outdoor spaces has decreased in recent times, as priorities lie in housing as many as possible, often with disregard to beneficial features such as access to outdoor areas in residential developments.
In terms of living conditions the lack of access to these spaces presents evident inequalities, uncovered during periods of lock down and restrictions during the pandemic. People were confined to their homes and local outdoor spaces, where they could exercise. Those who had access to these public spaces and had their own gardens/external space were very lucky in the sense that they were able to enjoy an element of the outside. While those less fortunate in flats and areas of depravity faced claustrophobic and demoralizing conditions, contained within the shell of their homes.
Windows are the elements that connect us to the outside world. It is from them that views are framed, privacy, lighting and natural ventilation are defined. Nowadays in the construction market we find different types of openings. Find out how to choose the type that best fits your project needs here.
Understanding how shadows will act in and around an area is a necessary understanding to ensure greater spatial quality. Shadows can influence natural lighting - therefore, the perception of space - and also issues of thermal comfort. Thus, mapping your projections and visualizing their movements during each season of the year can be fundamental to improve your project. The good news is that there are simple tools that help you visualize this in your city and in natural environments.

Our environment influences how we feel; we have all experienced this. For students, it is easier to study in a bright place, artists look for inspiring atmospheres, and our mood can improve with the right color scheme. These aspects are also important for kindergartens, daycare centers and schools, because a child-friendly design can stimulate the curiosity and imagination of children, so that they learn in a playful way. The design of a room supports the learning and creativity of children. Daylight systems, for example, flood rooms with light, making them appear larger and friendlier.
People have fundamental needs that must be met in order to survive, which include: oxygen, water, food, sleep, and shelter. They also have secondary requirements, one of which is daylight. When thinking about how buildings can keep people healthy, it is important to remember that daylighting is essential to wellness, in fact, human circadian rhythms are dependent on it.
Lighting design for exhibition spaces in museums can be quite challenging because light must simultaneously enhance the space, preserve the integrity of the artworks and highlight them in a way that ensures the best conditions for the visitor's enjoyment.
In addition to having the highest CRI (Color Rendering Index), daylight contributes to a feeling of comfort and well-being in the built environment. In exhibition spaces, natural lighting is important to accurately reveal the colors of the objects on display, which is very significant for works of art and provides more visual comfort for visitors to clearly perceive the exhibits.
In a 2016 survey of 400 employees in the U.S., Saint-Gobain found that office building occupants commonly complained about poor lighting, temperature, noise, and air quality, leading the company to deduce a need for improved lighting and thermal comfort in buildings while also maintaining low energy consumption and freedom of design for architects and clients. Their solution was SageGlass, an innovative glass created first in 1989 and developed over the course of the past three decades. The glass, which features dynamic glazing protecting from solar heat and glare, simultaneously optimizes natural light intake. A sustainable and aesthetic solution, SageGlass’ adaptability to external conditions dispels the need for shutters or blinds.
