Heating Kevin Hampson Was having trouble figuring out how to present this information. Thought it would interesting to present in a manner that mimicked my thought process while studying.
Why do we heat? At the most basic level, why do we heat? Whether it be a person, place, or thing, why? To make something warm or hot. But why? Often times, it is to make something do something it cannot normally do when it is cool. Sometimes, very high temperatures are needed (such as smelting). Heat is essential to life. As people, why do we heat ourselves? “So we don’t get cold.” Good answer, but is there a lower level need for heating ourselves? “So we don’t die of being cold.” Let’s really drive home this idea...
Thin Margin of Error Normal Cold Hot 97.5 F - 99.5 F Hypothermia Medical Emergency Probably Dead Definitely Dead < 95 < 90 < 85 < 80 Hyperthermia Medical Emergency Probably Dead Toast > 102 > 106 > 110 > 112
Regulation Tangible benefits of control. Intangible drawbacks of comfort. Benefits of control: concern for life not an issue. Can also do things we normally could not (live in area during winter, work on this project with artificial light). Detriments of control: Seneca iscusses moral repercussions of such luxury, chastises man with warm feet, home, and lovely windows as being timid of the outside, if not completely disgusted by it. Also, perfect sustainability could assume no humans or no human exploitation. If we didn’t exploit, our lives would be prettty terrible.
Exercising Control Practical and moral aspects of: Planning Passive heating Doing whatever it takes to get this damn house warm. Three main aspects of the Villa: Planning Passive Solar Heating Hypocaust System
Hypocausts “Hot Air Room” Generally located underneath main floor with furnace. Attached to bath and near living areas (along with propnigeion). Furnace attached to pipes which lined walls.
Vitruvius
Natural Draft Furnace
Closing Remarks About cooling... Important to consider the practical and moral considerations. Heat as an all encompassing topic. Solidifying Pliny and Vitruvius. The “Greatness” of the Ancients.
