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.
As part of Velux's Build for Life online conference, ArchDaily will be hosting the Daylight in Architecture Sessions. Today, Cristian Izquierdo Lehmann, Jose Fernando from Natura Futura, and Rick Joy will discuss how to leverage buildings to benefit the environment and improve the quality of life.
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.
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.
