ABSTRACT
Flynn and Segil Stated: "But rather than a simple correction of climatic deficiencies, the environmental control function of building must be oriented toward the more extensive sensory demands of various occupant activities and experiences". Designing for environmental control of the building envelope assembly compels professionals to integrate two very different conceptual processes. One extreme encompasses analytic thinking, involving testing and calculations; the other encompasses analog thinking, based on broad experience and judgment based on an understanding of what makes a building envelope function. The building envelope must perform, retaining its structural integrity, while separating the interior and exterior environments. The building should be analysed as a whole at the same time when each of its components is analysed. The environmental control must also be a part of this analysis if the interactions and trade-off between control of heat, air, and moisture transports are to be fully realized.
