Most if not all commercial antifreeze formulations intended for use in heat transfer applications include anti-corrosion and anti-cavitation agents (that protect the hydraulic circuit from progressive wear). Many formulations have corrosion inhibitors, and it is expected that these chemicals will be replenished (manually or under automatic control) to keep expensive piping and equipment from corroding. Also, plain water would increase the prevalence of galvanic corrosion. Salts are frequently used for de-icing, but salt solutions are not used for cooling systems because they induce corrosion of metals. Similar mixtures are commonly used in HVAC and industrial heating or cooling systems as a high-capacity heat transfer medium. The most common water-based antifreeze solutions used in electronics cooling are mixtures of water and either ethylene glycol (EGW) or propylene glycol (PGW). An antifreeze is an additive which lowers the freezing point of a water-based liquid. Commercially, both the additive (pure concentrate) and the mixture (diluted solution) are called antifreeze, depending on the context. Inhibited ethylene glycol antifreeze mixes are available, with additives that buffer the pH and reserve alkalinity of the solution to prevent oxidation of ethylene glycol and formation of these acids.
When building a house, they are glued together and secured with lumber. Approaches include referencing key metrics such as the Facility Condition Index (FCI), or using 3D laser-scanning surveys and photogrammetry techniques (separately or in combination) or digitizing traditional building surveying methodologies by using mobile technology to capture accurate measurements and operation-related information about the asset that can be used as the basis for a model. Use of a shared digital representation of a built asset to facilitate design, construction and operation processes to form a reliable basis for decisions. The fire code is aimed primarily at preventing fires, ensuring that necessary training and equipment will be on hand, and that the original design basis of the building, including the basic plan set out by the architect, is not compromised. Morrell also told construction professionals to adopt BIM or be "Betamaxed out". Created in 2015 to promote the adoption of BIM in Portugal and its normalisation, the Technical Committee for BIM Standardisation, CT197-BIM, has created the first strategic document for construction 4.0 in Portugal, aiming to align the country's industry around a common vision, integrated and more ambitious than a simple technology change.
However, all common antifreeze additives also have lower heat capacities than water, and do reduce water's ability to act as a coolant when added to it. Common antifreezes also increase the boiling point of the liquid, allowing higher coolant temperature. In April 2016, the UK Government published a new central web portal as a point of reference for the industry for 'level 2 BIM'. The first industry-level BIM conference was held in April 2008, after which, BIM has been spread very rapidly. Ethylene glycol solutions first became available in 1926 and were marketed as "permanent antifreeze" since the higher boiling points provided advantages for summertime use as well as during cold weather. Solutions of organic compounds, especially alcohols, in water are effective. Water was the original coolant for internal combustion engines. The term engine coolant is widely used in the automotive industry, which covers its primary function of convective heat transfer for internal combustion engines.
Because water has good properties as a coolant, water plus antifreeze is used in internal combustion engines and other heat transfer applications, such as HVAC chillers and solar water heaters. They are used today for a variety of applications, including automobiles, but there are lower-toxicity alternatives made with propylene glycol available. PGW is generally recognized as safe for use in food or food processing applications, and can also be used in enclosed spaces. This results in slightly less fuel use and therefore less greenhouse gas production. Low molecular weight organic compounds tend to have melting points lower than water, which makes them suitable for use as antifreeze agents. Salts lower the melting points of aqueous solutions. However, EGW solutions formulated for the automotive industry often have silicate based rust inhibitors that can coat and/or clog heat exchanger surfaces. Will we have to get used to "BIM Washing"? Some purposes or uses of BIM may be described as 'dimensions'. DEX-COOL antifreeze uses two inhibitors: sebacate and 2-EHA (2-ethylhexanoic acid), the latter which works well with the hard water found in the United States, but is a plasticizer that can cause gaskets to leak. Although EGW has more desirable physical properties than PGW, the latter coolant is used in applications where toxicity might be a concern.
