Air conditioning and fluorescent lighting were both introduced in the early to mid twentieth century, and had a profound impact on architecture. The ability to inexpensively and artificially light a space eliminated our dependency on natural daylight, and artificial cooling removed the need for cross ventilation and operable windows. As a result, buildings became a collection of separate systems – the envelope, heating/cooling, and lighting were now all dealt with independently. The form of our buildings, driven by land and construction costs, became deep, square, and with the introduction of cable borne electric elevators, tall. What wasn’t diminished was our psychological need for natural light, fresh air and a connection to the outdoors. The “corner office” became a status symbol because of it’s access to views and light. In the developed world, we quickly forgot how to design and build naturally ventilated, naturally lit buildings that worked in the context of their environment.
