Based on a review by Abu Dhabi’s Urban Planning Council (UPC), up to five pearls can be awarded. One pearl is mandatory for all developments and is based on the building code. As per Information Bulletins No. 1 [7] dated 6 December 2010 all Abu Dhabi government projects are required to achieve two pearls. Two pearls include all the mandatory ...
Although the concept of U-value (or U-factor) is universal, U-values can be expressed in different units. In most countries, U-value is expressed in SI units, as watts per square metre-kelvin: W/(m 2 ⋅K) In the United States, U-value is expressed as British thermal units (Btu) per hour-square feet-degrees Fahrenheit: Btu/(h⋅ft 2 ⋅°F)
The U-value is used to refer to the amount of heat that can pass through a window, called thermal transmittance, with a lower score being better. [1] The U-factor of a window can often be found on the rating label of the window. Although the concept of U-value (or U-factor) is universal, U-values can be expressed in different units. In most ...
Architects and engineers call the resulting values either the U-Value or the R-Value of a construction assembly like a wall. Each type of value (R or U) are related as the inverse of each other such that R-Value = 1/U-Value and both are more fully understood through the concept of an overall heat transfer coefficient described in lower section ...
Within Estidama, however is a green building rating system called the Pearl Rating System [2] that is utilized to evaluate sustainable building development practices in Abu Dhabi. The Estidama program is mandatory in Abu Dhabi, United Arab Emirates - all buildings must achieve a minimum 1 Pearl Rating, and all government-funded buildings must ...

Fisher's k-statistics and Tukey's polykays are examples of homogeneous polynomial U-statistics (Fisher, 1929; Tukey, 1950). For a simple random sample φ of size n taken from a population of size N, the U-statistic has the property that the average over sample values ƒ n (xφ) is exactly equal to the population value ƒ N (x). [clarification ...
Note that the value of U (but not H!) is independent of the base of the log since all logarithms are proportional. The uncertainty coefficient is useful for measuring the validity of a statistical classification algorithm and has the advantage over simpler accuracy measures such as precision and recall in that it is not affected by the relative ...
