Ecological life cycle analysis (LCA) on the example of materials used in warehouse buildings [PDF]

open access: yesArchives of Civil Engineering
Construction cannot be called as an environment friendly process, hence many solutions are being developed to define the negative interactions of the buildings, determine the extent of environmental impact and find alternatives to improve design ...

Low-GWP refrigerants for medium and high-pressure applications [PDF]

open access: yesInternational Journal of Refrigeration, 2017
The merits of an alternative refrigerant are established based on many attributes including environmental acceptance, chemical stability in the refrigeration system, low toxicity, flammability, efficiency and volumetric capacity. In an earlier work, these criteria were used to screen a comprehensive database to search for refrigerants with low global ...
