Although the architecture, engineering and construction (AEC) industry is highly relevant to national development, it suffers from significant productivity challenges. Beneath the design and documentation of structures, a dynamic, complex process is taking place, with constant modifications and feedback involving numerous professionals from different fields and their respective approaches and work developed using various computer programs. This diversity of factors converges within an iterative trial-and-error process and does not stop until a refined model is achieved. To understand traditional structural engineering companies (SECs) in Chile involved in building private procurement projects, 25 non-value-adding SEC activities were identified and classified according to typical lean management waste categories. These were initially validated by a panel of experts and then confirmed through a survey of 37 companies. The identified activities reduce the productivity of SEC organizations, contributing to low AEC industry indicators.

Cavity solar receivers are generally believed to have higher thermal efficiencies than external receivers due to reduced losses. A simple analytical model was presented by the author which indicated that the ability to heat the air inside the cavity often controls the convective loss from cavity receivers. Thus, if the receiver contains a large amount of inactive hot wall area, it can experience a large convective loss. Excellent experimental data from a variety of cavity configurations and orientations have recently become available. These data provided a means of testing and refining the analytical model. In this manuscript, a brief description of the refined model is presented. Emphasis is placed on using available experimental evidence to substantiate the hypothesized mechanisms and assumptions. Detailed comparisons are given between analytical predictions and experimental results. Excellent agreement is obtained, and the important mechanisms are more clearly delineated.
