Introduction: Material & Façade Performance A1. Lexicon Durability The ability of a physical product to remain functional, without requiring excessive maintenance or repair, when faced with the challenges of normal operation over its design lifetime. There are several measures of durability in use, including years of life, hours of use, and number of operational cycles. 1899 years Pantheon Rome - rebuilt 125 AD anno domino 6-9 million visitors/year For educational purposes only Corrosion Destruction of material by chemical means. Erosion Destruction of material by climat conditions. For educational purposes only Robustness High resistance to mechanical failure, including damage from climate load and design properties that facilitate simple and durable solutions, which relates to both the production and operational phase of the building or its components.

Humanity should use these resources in such a way that they can be maintained over a long period of time, rather than being depleted. They key idea here is being mindful of future generations, which is why sustainability is sometimes also referred to as “future viability” and “intergenerational equity”. Climate protection is thus an intrinsic part of sustainability. It’s about actively considering the environment, economy and society and making the effort to bring them into balance. ‘Made from renewable resources and can be recycled into other items, thus reducing waste processes and preserving the environment’ For educational purposes only For educational purposes only Sustainability For educational purposes only Sustainability For educational purposes only Circularity For educational purposes only EVALUATION TESTING + DESIGNING INTEGRATION For educational purposes only Circularity For educational purposes only Light transmitting Light transmission is also known as visible light transmission rate, which indicates the ability of light to pass through the medium. It refers to the percentage of luminous flux through transparent or translucent materials compared to the incident luminous flux. For educational purposes only Porosity Is a measure of the void (i.e. “empty”) spaces in a material, and is a fraction of the volume of voids over the total volume, between 0 and 1, or as a percentage between 0% and 100%. Absorption (a) The process whereby a liquid is drawn into the permeable pores of a porous solid. (b) Absorption of sound. See SOUND ABSORPTION. (c) Energy absorption. Inertia Thermal inertia is the tendency of a material to resist changes in temperature. For educational purposes only Relative humidity Relative humidity, expressed as a percent, measures the current absolute humidity relative to the maximum for that temperature (which depends on the current air temperature). A reading of 100 percent relative humidity means that the air is totally saturated with water vapor and cannot hold any more, creating the possibility of rain in the atmosphere and condensation in the factory. Further, when the moisture content remains constant and temperature increases, relative humidity decreases. For example if we have air at 22°C and 55% we would have an absolute humidity level of 9 g/kg. Warmer air can hold more humidity. So, if we increase the temperature to 30°C but keep the absolute humidity the same (9 g/kg) the relative humidity would now be 34% RH. Similarly if we decrease the temperature from 22°C to 12 °C and kept the absolute humidity the same we would now have a relative humidity of 100% RH. Water vapour pressure Water vapour moves from a side with higher vapour pressure (partial pressure) to a side with lower pressure. If the temperature falls below the dew point, condensation can occur (with a risk of condensate accumulating and mould forming). For educational purposes only Dew point The dew point is the saturation temperature for water in air. The dew point is associated with relative humidity. A high relative humidity implies that the dew point is closer to the current air temperature. Relative humidity of 100% indicates the dew point is equal to the current temperature and that the air is maximally saturated with water. 22°C and 100% RH the air will have a dew point of 22°C. 22°C and 55% RH has a dew point of 12°C. So if cooled this air down, 12°C is the temperature at which moisture will be released from the air and condense on surrounding surfaces. For educational purposes only Water vapour pressure For educational purposes only Moisture transfer Vapor barrier Reverse position of the vapor barrier (Porto - Portugal) For educational purposes only Vapor barrier The vapor diffusion resistance or µ value For educational purposes only Compressive strenght The resistance of a material to breaking under compression Tensile bending strenght The maximum stress that a material can bear before breaking when it is allowed to be stretched or pulled. Yield strenght Yield strength is a measure of the stress at which a material begins to undergo plastic deformation. In other words, it is the point at which a material transitions from elastic deformation, where it can return to its original shape, to plastic deformation, where it remains permanently deformed. Yield strength is typically expressed in units of pressure, such as Pascals (Pa) or pounds per square inch (psi). For educational purposes only Fire reaction class For educational purposes only Fire reaction class For educational purposes only Fire reaction class For educational purposes only Fire resistance For educational purposes only Combustibility / flammability A combustible material is a material that can burn (i.e., sustain a flame) in air under certain conditions. A material is flammable if it ignites easily at ambient temperatures. In other words, a combustible material ignites with some effort and a flammable material catches fire immediately on exposure to flame. Thermal conductivity For educational purposes only Thermal conductivity For educational purposes only Thermal expansion Thermal expansion is the tendency of matter to increase in length, area, or volume, changing its size and density, in response to an increase in temperature (usually excluding phase transitions). Substances usually contract with decreasing temperature (thermal contraction), Winter / summer?
