At best, this increases energy costs and can lead to poor quality steam, reduced efficiency, shorter plant life and unreliable operation. Dynamic information about the building, such as sensor measurements and control signals from the building systems, can also be incorporated within software to support analysis of building operation and maintenance. Aish, R. (1986) "Building Modelling: The Key to Integrated Construction CAD" CIB 5th International Symposium on the Use of Computers for Environmental Engineering related to Building, 7-9 July. The Russian government has approved a list of the regulations that provide the creation of a legal framework for the use of information modeling of buildings in construction and encourages the use of BIM in government projects. Lithuania is moving towards adoption of BIM infrastructure by founding a public body "Skaitmeninė statyba" (Digital Construction), which is managed by 13 associations. Public Services and Procurement Canada (formerly Public Works and Government Services Canada) is committed to using non-proprietary or "OpenBIM" BIM standards and avoids specifying any specific proprietary BIM format. 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. Traditionally, there were two major corrosion inhibitors used in vehicles: silicates and phosphates. Japanese makes traditionally use phosphates and other inhibitors, but no silicates. American-made vehicles traditionally used both silicates and phosphates. European makes contain silicates and other inhibitors, but no phosphates. P-HOAT coolants mix phosphates with HOAT. Honda and Toyota's new extended life coolants use OAT with sebacate, but without the 2-EHA. Some added phosphates provide protection while the OAT builds up. FDA allows propylene glycol to be added to a large number of ultra-processed foods, including ice cream, frozen custard, salad dressings, and baked goods, and it is commonly used as the main ingredient in the "e-liquid" used in electronic cigarettes. However, the terms 'Building Information Model' and 'Building Information Modeling' (including the acronym "BIM") did not become popularly used until some 10 years later. COBie has been incorporated into software, and may take several forms including spreadsheet, IFC, and ifcXML. Larger systems (such as HVAC systems) are often monitored by specialist firms which take responsibility for adding corrosion inhibitors and regulating coolant composition. Maintenance of systems using glycol solution includes regular monitoring of freeze protection, pH, specific gravity, inhibitor level, color, and biological contamination. Glycerol is mandated for use as an antifreeze in many sprinkler systems. Most commercial antifreeze formulations include corrosion inhibiting compounds, and a colored dye (commonly a fluorescent green, red, orange, yellow, or blue) to aid in identification. Typically, OAT antifreeze contains an orange dye to differentiate it from the conventional glycol-based coolants (green or yellow), though some OAT products may contain a red or mauve dye. Some of the newer OAT coolants claim to be compatible with all types of OAT and glycol-based coolants; these are typically green or yellow in color. Si-OAT coolants mix silicates with HOAT. HOAT coolants typically mix an OAT with a traditional inhibitor, usually silicates. A HOAT coolant can have a life expectancy as high as 10 years / 180,000 miles. Once used for automotive antifreeze, glycerol has the advantage of being non-toxic, withstands relatively high temperatures, and is noncorrosive. Glycerol was historically used as an antifreeze for automotive applications before being replaced by ethylene glycol. However, since 2018, they have moved on to G12EVO (TL 774-L) which no longer contains glycerol. To maximize radiative cooling at night, they are often chosen to have high thermal emissivity, whereas their low emissivity for the solar spectrum reflects heat during the day. The classic version has a thermal resistance (R value) of 3.7 per inch and other versions have even higher values. Silica aerogel has the lowest thermal conductivity of any known substance (short of a vacuum), and carbon aerogel absorbs infrared radiation (i.e., heat from sun rays) while still allowing daylight to enter. Superheated steam boilers evaporate the water and then further heat the steam in a superheater, causing the discharged steam temperature to be substantially above the boiling temperature at the boiler's operating pressure. This exposes hot engine components to air and vapors, causing corrosion and contamination of the coolant with iron oxide particles, which in turn can aggravate the pressure cap problem as contamination holds the caps open permanently. The low coolant is caused by pressure caps that fail in the open position.
