Design methodology is the systematic description of the technical design process of industrial air technology as an elementary part of the whole life cycle of the industrial plant. 

The need for the implementation of target levels for air quality in industrial work rooms stems from different concerns. In addition to technological factors, the systematic design methodology, life cycle assessment, advances in air distribution methods, and increased integration with the process and... 

As an example, Baitz et al7 focused on different technologies and peripheral system conditions to reduce dust and heavy metal emissions from a refinery. They stressed that the knowledge of the sensitive life cycle parameters and a suitable database, and thus the possibility to quantify impacts, enables a sustainable decision-making in process design and process optimisation. 

This checklist should not be used in a rote "yes/no" manner, nor is it necessary to answer every question. The idea is to consider what might be possible, and then determine what is feasible. The checklist should be reviewed periodically throughout the life cycle of the process. As technology changes, what was once impossible becomes possible, and what was once infeasible becomes feasible. 

Effective design of a remediation system for dissolved hydrocarbons in groundwater requires consideration of more than only the effectiveness of the technological process involved. At many sites a variety of techniques are capable of completing the cleanup. However, design of a project that is efficient in all aspects — technically, in terms of time, and economically — requires an evaluation of the entire life cycle of the project from inception to closure. Typically, at sites where remediation is expected to continue over a 4-year project life, operation and maintenance account for between 50 and 80% of the total project cost. These percentages increase each year thereafter. The principal components of operation and maintenance are power, labor, and parts. Identification and quantification of these components are critical to the overall cost of a project.
