For example, when a goal on energy reduction is set (conceptualization), engineers who have design skills are needed while technicians take charge of maintenance and operation.
Besides building orientation, architects, civil/structural/ environmental engineers should also be able to choose materials based on thermal resistant and building systems based on their environmental and energy cost over the life cycle of the building [10].
They are professionals in architecture, engineering, quantity surveying or other building related disciplines as recognized by the GBI Accreditation Panel.

The concept lattice of distress causes was analyzed, and improvement strategies for pavement engineers are proposed.
For the first ten years, FCA was used in several larger-scale knowledge exploration systems for civil engineering [7].
Information about pavement engineers’ knowledge was collected using questionnaire surveys.
FCA is clearly a useful method for pavement engineers to further analyze information related to asphalt pavement distresses.
