Temperature distribution in a thermal bridge This thermal image shows a thermal bridging of a high-rise building (Aqua in Chicago). A thermal bridge, also called a cold bridge, heat bridge, or thermal bypass, is an area or component of an object which has higher thermal conductivity than the surrounding materials, [1] creating a path of least resistance for heat transfer. [2]
The calculation of the heat loss due to linear thermal bridging is relatively simple, given by the formula below: [3] H T B = y ∑ A e x p {\displaystyle H_{TB}=y\sum A_{exp}} In the formula, y = 0.08 {\displaystyle y=0.08} if Accredited Construction details used, and y = 0.15 {\displaystyle y=0.15} otherwise, and ∑ A e x p {\displaystyle ...
Avalanche blasting in the French ski resort of Tignes (3,600 m or 11,800 ft) Gazex installation. Active techniques reduce the risk of an avalanche occurring by promoting the stabilization and settlement of the snow pack through three forms of intervention: disrupting weak layers in the snow pack, increasing the uniformity of the snow pack, and lessening the amount of snow available in snow ...

The bridge was listed in the National Register of Historic Places in 1996. After the completion of the Veterans Memorial Bridge, the Rainbow Bridge was closed for renovations. On its re-opening in 1997, [4] the Rainbow Bridge became one way, handling westbound traffic only. In January 2014, refurbishment project started. [5]
The climate in Texas is changing partially due to global warming and rising trends in greenhouse gas emissions. [1] As of 2016, most area of Texas had already warmed by 1.5 °F (0.83 °C) since the previous century because of greenhouse gas emissions by the United States and other countries. [1]

In addition to the construction of 43 permanent bridges, six temporary bridges were built, resulting in 2.3 million cubic feet (0.065 × 10 ^ 6 m 3) of bridge deck. [ 5 ] The project was designed by HNTB , [ 4 ] who provided professional engineering consultation throughout the construction, [ 15 ] which had begun in 2002 and was completed in ...
