From subtle light beams to wide openings, skylights transform natural light into a powerful architectural tool, creating a dynamic interplay of light and shadow that adds movement and vitality to buildings. This intricate dance captivates not only with the patterns the light casts on surfaces but also with the practical benefits of overhead lighting, such as improved thermal comfort and enhanced well-being.
The main role of architecture is to create structures that protect us from the environment and create spaces that are safe and comfortable for all types of needs and activities. By providing shelter, architecture also shapes the way people interact with their surroundings. Building technologies of the past rarely managed, however, to create a complete separation between us and the outside world.
While impermeability was a desired outcome, the porous building materials available always allowed some water, wind, or outside particles to leak into the interior spaces. In contrast, modern technologies now allow for almost completely impermeable building envelopes, allowing for complete separation between indoors and outdoors, thus relying on engineered systems to regulate temperature, airflow, or humidity. This article explores the differences between these two contrasting approaches, exploring how building facades are equipped to regulate indoor comfort and its environmental impact.
Throughout history, sunshades--light-weight screens typically made of interwoven wooden reeds--have been the go-to method of sun protection and temperature control for dwellings across civilizations, especially those located in tropical and Mediterranean climates. While offering protection from the sun's heat and rays, sunshades also allow air to permeate, making them an effective and economical cooling system for interior spaces.
