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.

Solar radiation is one of the most important criteria in architectural projects, as it impacts several decisions ranging from the orientation of the building on the site to the choice of windows and doors. Therefore, to ensure the quality of lighting and visual comfort in building interiors, it is crucial to study the sun path and the quantity of sunlight in each given space.
When designing a space, architects across the board tout the importance, and even necessity, of incorporating natural light into interiors. This means taking measures to control the quantity of light being let in and its distribution throughout the space.
In the case of residential spaces, where privacy plays a larger role than in public spaces like offices, restaurants, and stores, opaque materials like screens, tinted glass, and other barriers are the go-tos for providing protection and privacy from the outside; however, the privacy that these methods provide often comes at the cost of the space's natural lighting, forcing designers to seek alternative materials that allow for both light and privacy.
While some aspects of comfort and well-being in an indoor environment are related to external factors, such as natural lighting and ventilation, others are directly associated with the interior layout and the sensations created by architecture in the people living in that space.
It is always challenging to balance all of the elements that can provide greater comfort and well-being in interior design, particularly in small environments that must be fully optimized since it is not always possible to create large openings to the outside or even to accommodate the whole architectural program in a conventional manner.
In dystopian films, it is a common trope to depict the sky as filled with a thick fog, blocking the sun's rays and bringing a dark atmosphere to the scenes. Whether in Blade Runner or in a Black Mirror episode, the lack of sun commonly represents a future we would rather not live in. The sun provides heat to planet Earth and is a great source of light energy, essential for the survival of many living creatures. We can generate electricity from the sun and still use only a fraction of the energy it provides. Sunlight also regulates our circadian cycle, which affects our mood. But recent forest fires and industrial pollution in some large cities have already made the dystopian blockage of sun a relatively common phenomenon, depriving hours of sunshine from many inhabitants. Concurrently, with the COVID-19 pandemic, we are living a plot that few science fiction writers could have predicted, and new technologies and solutions have emerged to try to contain the spread of this invisible enemy. Can the sun, or specifically ultraviolet radiation, kill viruses and bacteria? Could it kill the coronavirus?
In 2016, the last modern masterpiece designed by world renowned architect Marcel Breuer, the Atlanta Fulton County Public Library, was slated for demolition. One of the Fulton County commissioners described the original design as looking “more like a jail” than a welcoming space for learning and productivity. To save the iconic building from the wrecking ball, changes would have to be made. This case study from cove.tool shows how energy and daylighting analysis is useful not only in new construction, but for revitalizing existing buildings as well.
Whether by traditional windows, linear openings in the wall, or skylights, the manipulation and incorporation of natural lighting in architectural projects can render a radical change in interior spaces.
Hessenwald School in Weiterstadt, Germany, is an example of energy-efficient, contemporary architecture that offers a new teaching and pedagogical model. At the centre of both model and building stands a well-lit and well-ventilated three-storey atrium.
On the UNESCO International Day of Light, The Daylight Award announces its 2020 Laureates: Juhai Leiviskä for his architecture, Russell Foster for his research, and this year, exceptionally, The Daylight Award is also given to Henry Plummer for his lifetime achievement.
'While laureate Russell Foster studies the science behind the effect of light on human behaviour and physical and mental wellbeing, laureates Juha Leiviskä and Henry Plummer approach the effects and implications of daylight intuitively through architectural design, photographic expression and verbal mediation of these human responses. Whether elucidating the neural effects of light or invoking the poetic essence of light, the laureates of the 2020 Daylight Award demonstrate to us the power of natural light,' states the jury.

Humans spend almost 90% of the time indoors; that's approximately 20 hours a day in closed rooms and 9 hours a day in our own bedrooms. The architectural configurations of these spaces are not random - that is, they have been designed or thought of by someone, and are at least slightly "guided" by the conditions of their inhabitants and their surroundings. Some people inhabit spaces specially catered to their needs and tastes, while others adapt and appropriate designs made for someone else, perhaps developed decades before they were born. In either case, their quality of life may be better or worse depending on the decisions that are made.
Understanding the importance of carefully designing our interiors, particularly through the lens of access and enjoyment of natural light, was the purpose of the 8th VELUX Daylight Symposium, held on October 9 and 10 of 2019 in Paris. This year, more than 600 researchers and professionals attended and reaffirmed the importance of natural light, presenting a series of concrete tools that could help quantify and qualify light by designing its entry, management, and control with greater depth and responsibility.
The BLL Awards for Architecture & Design comes from “Bringing light to life” which is the slogan of VELUX world brand for roof windows, which distribute daylight and fresh air into buildings through the roof. The idea of the Awards is to popularize good architecture, from architects and designers across countries in the CEE (Central and Eastern Europe) region, which demonstrates the effective distribution of daylight into buildings and the utilization of the space under the roof elements. It is a platform to showcase the work and products of architects and designers to a global audience. This year is the 6th edition of the BLL Awards, and is now open for entries. Seven countries from the CEE region are included – Bulgaria, Bosnia and Herzegovina, Romania, Serbia, Macedonia, Montenegro, and Turkey.
It's very likely that you are reading this text in an interior space with the lights on. For most people, modern living entails spending most of the day in closed rooms, bathed in a sum of artificial and natural lights. Yet while artificial light has afforded mankind incalculable possibilities, it has also caused some confusion in our bodies, which have evolved for thousands of years to respond to the stimuli of sunlight in the day and darkness at night. This responsiveness to natural light is called the circadian rhythm or cycle, and describes the 24-hour biological cycle of almost all living beings. Circadian rhythms are primarily influenced by light reception, but temperature and other stimuli also play a role in the process.
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.
While many architects consider windows for brightening interior spaces, Norman Foster is intrigued by natural light from above. The British star architect has long held Louis Kahn and Alvar Aalto in high esteem for how they handled daylight - especially with regard to the roof. In particular large public buildings benefit from this strategy creating enjoyable spaces. Therefore, Foster regards daylight from above as indispensable when he develops megastructures for airports on the ground or tall skyscrapers for work. But daylight from above is much more than an aesthetic dimension, remarks Foster: "Quite apart from the humanistic and poetic qualities of natural light there are also energy implications."
Did you know that 64 million European children spend more time at school than anywhere else other than their home? European children spend approximately 200 days each year at their primary schools. With this information, how do we go about designing healthier classrooms that create productive learning environments? This question is perhaps more important than ever, as this will be the first time since the 1970s that Europe and the UK will see a boom in the construction and renovation of schools. What a tremendous opportunity this is for both architects and educators to rethink what an educational facility should be and how the physical environment can be designed to have a positive impact on learning.
Recurrently we see how architects opt for translucent facades to create the envelopes of their buildings, promoting the entry of a large amount of natural light, while simultaneously controlling it during the day. Illuminated during the night, many of these projects can be seen in the dark, appearing as lanterns or lighthouses for their neighbors and community. Being exposed to changing conditions – day or night – to choose the right material, it's necessary to study in detail the orientation and location of the building, the pre-existing context, and the configuration of the interior spaces.
We present a system of glass panels that allow buildings with this type of façade –spanning from floor to ceiling without interruptions – with minimal frames and different colors, textures, thermal and acoustic performances.
Held every two years, the International VELUX Award challenges students to generate projects that take advantage of daylight, with the aim of developing a deeper understanding of this energy source.
A jury of renowned architects chose 9 regional winners for its 2018 iteration, who will now compete for the winning title at the World Architecture Festival in November. The winners were chosen from projects presented by students from 250 different architecture schools in 58 countries.

Hiroshi Sambuichi's approach to a site entails long-term study and reflection upon the qualities and forces of nature embedded within. His understanding is “deeper and with a finer grain,” explains American architect and member of The Daylight Award jury James Carpenter as one of several reasons why Sambuichi was recently announced as the latest laureate of the nearly 50-year-old Daylight Award in 2018. In Sambuichi's hands, “light becomes timeless, fluid and rich.”
