As our cities densify and building types become more and more mixed-use, we tend to spend a lot of time in noisy environments. When we think about acoustic comfort, we rarely think of places like restaurants, venues, and big offices; places with a lot of people, machinery, and background noise. The quality of sound can entirely change the experience of people in an interior space, and improving the space's acoustic quality relies on treating all surfaces, from walls to ceilings, and flooring. In this article, we will present a variety of solutions for ceilings, flooring, and walls, their different combinations, and a simple guide of how to apply them correctly in public spaces without compromising the aesthetic of the interior.
The choice of Lacaton & Vassal to receive the 2021 Pritzker Prize was, above all, emblematic. Under the mantra “never demolish, never remove or replace, always add, transform and reuse”, the French duo built a career focused on renovating buildings, providing them with spatial quality, efficiency and new programs. Their approach contrasts with most of the architecture we are used to honoring: iconic, imposing and grandiose works. It also contrasts with the notion of the tabula rasa, of building and rebuilding from scratch, so well represented in Le Corbusier's Ville Radieuse, and which has fascinated architects and urban planners ever since.
Multi Comfort: Meet the Winners of the 16th Edition of the Saint-Gobain International Student Contest
Saint-Gobain has announced the results for the 16th edition of its international Multi Comfort Student Contest. This year, the challenge was to convert the post-industrial area of the Coignet company in Saint-Denis (France) into a space for living, learning, and leisure in the heart of a large green space, respecting both the historical heritage and the needs of sustainable development of modern neighborhoods, in collaboration with the city of Saint-Denis.

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.
Ventilation serves two main purposes in a room: first, to remove pollutants and provide clean air; second, to meet the metabolic needs of the occupants, providing pleasant temperatures (weather permitting). It is well known that environments with inadequate ventilation can bring serious harm to the health of the occupants and, especially in hot climates, thermal discomfort. A Harvard University study demonstrated that in buildings with good ventilation and better air quality (with lower rates of carbon dioxide), occupants showed better performance of cognitive functions, faster responses to extreme situations, and better reasoning in strategic activities.
Just before the global lockdowns began in response to the spread of the widely discussed COVID-19, we met with Saint Gobain experts at their new headquarters in Paris to discuss an extensive investigation conducted in 2019, with the aim of understanding the transformations that architecture and construction have experienced in recent years. After an interesting exchange of ideas, we chose the most relevant topics to be analyzed in depth by our team of editors, resulting in a series of articles that combined the trends identified with the unexpected events that occurred during 2020, connecting them directly to architectural design.
There was a time when people appreciated self-contained architecture, in which the building envelope would not function as a moderator between the climate outside and the interior environment but rather as an inert and independent barrier. Countless mechanical devices and electrical ventilation, heating, and cooling equipment. A real machine.
At the 2016 Venice Architecture Biennale, curator Alejandro Aravena decided to reuse 100 tons of material discarded by the previous Art Biennale to create the new exhibition halls. Besides preserving 10,000 m² of plasterboard and 14 km of metallic structures, the initiative intended to give value, through design, to something that would otherwise be discarded as waste. The project also shed light on another observation: as architects, we generally restrict ourselves to thinking about buildings during the design process, construction phase, and at most through the use phase. We hardly think of what will become of them when they are demolished at the end of their useful life, an issue that should urgently become part of the conversation.
In a predominately urban world that constantly has to deal with complex problems such as waste generation, water scarcity, natural disasters, air pollution, and even the spread of disease, it is impossible to ignore the impact of human activity on the environment. Climate change is one of the greatest challenges of our time and it is urgent that we find ways to slow down the process, at the very least. Toward this end, our production, consumption, and construction habits will have to change, or climate change and environmental degradation will continue to diminish the quality and duration of our lives and that of future generations.
