History of Ventilation Technology! Cooling and design!

Cooling in Buildings

Over time, there arose an increasingly large need to cool certain buildings. The primary purpose of ventilation was, of course, to remove polluted air but it had also gained acceptance for cooling purposes. During the 1800s, supply air was cooled either by spraying it with water or by letting it flow over blocks of ice in the air intakes. The ice industry was quite large at this time and, for example, Norway had a considerable shipping fleet that supplied winter ice to numerous countries and, not least, to the USA where there were numerous buildings that required cooling. However, towards the end of the 1800s, winter ice for ventilation cooling was replaced by machinemade ice. One of the major users was the Madison Square Theater in New York. In order to maintain a comfortable indoor temperature for the audiences, no fewer than 4 tons of ice were used during every evening performance!

Ventilation, indoor environment and desing of a building

One of the most important and prominent figures in the history of ventilation was David Boswell Reid, from Edinburgh, who energetically drove development forward during the 1800s. Reid mastered the fire-driven technology to almost complete perfection and was instrumental in bringing ventilation into the age of machines with steam-driven fans and systems, which, in many respects, are similar to those we use today. Reid realized, perhaps more than anyone else in his day, the importance of the interplay between ventilation, the indoor environment and the design of a building. In his opinion, architecture was all about enveloping a building and supplying it with a desired indoor environment.
