High temperatures and humidity in enclosed storage or exhibition space may lead to excess moisture that warps the painting. [11] High Humidity reduces mechanical damage such as brittle paint but raises the risks of biological organisms, e.g. white efflorescence and green-to-black stains on a panel painting. [12]
Increased heat from light creates paint soften: 68 °F ± 2° High temperature softens paint. low temperature causes brittle paint. Oil Paint [23] 40–45% or 45–45%: Expansion and contraction of painting, wood and fabric absorb moisture or shrink, paint cracks and flakes, or sags: max 200 lux: Fading or darkening of painting
A digital thermometer reading an ambient temperature of 36.4°C (97°F) in an unventilated room during a heat wave; a high indoor temperature can cause heat exhaustion or heat stroke in a person. The World Health Organization in 1987 found that comfortable indoor temperatures of 18–24 °C (64–75 °F) were not associated with health risks ...

A Assuming an altitude of 194 metres above mean sea level (the worldwide median altitude of human habitation), an indoor temperature of 23 °C, a dewpoint of 9 °C (40.85% relative humidity), and 760 mmHg sea level–corrected barometric pressure (molar water vapor content = 1.16%). B Calculated values *Derived data by calculation.
The stack effect is used both in traditional buildings and modern green architecture. Examples of traditional usage include the wind towers common in Middle Eastern architecture, which capture and direct cooler breezes into the building while expelling hot air to maintain comfortable indoor temperatures.

[contradictory] This type of clay is water-soluble and unstable. Earthenware is clay that has been fired between 1000–1200°C or 1832°–2192°F. The firing makes the clay water insoluble but does not allow the formation of an extensive glassy or vitreous within the body. Although water-insoluble, the porous body of earthenware allows water ...
