With most of the world living in cities and growing villages, people tend to spend the majority of their time indoors. When not at home, we are working, learning, or even engaging in fun activities in enclosed, built settings. All in all, 90% of our time is occupied inside. It is therefore essential to ensure a comfortable, productive, and healthy Indoor environmental quality by following well-regulated parameters and design practices that consider temperature, lighting, noise pollution, proper ventilation, and the quality of the air we breathe. The latter is especially important, since contrary to what we might think, air pollution is much higher indoors than outdoor.
