The building envelope plays an important role in maintaining interior thermal comfort and in minimizing uncontrolled moisture and air movement into a building. An effective building envelope design works towards minimizing heat transfer and preventing moisture and condensation problems. Because some of these considerations are not always apparent to Architects, the interaction between Architects and Mechanical engineers is crucial in creating a problemfree design. This paper aims to show the relationship between the architectural and mechanical aspects of the envelope design. This paper also details how the integrative design is implemented during the early design phases supported by several building envelope case studies for airports, hotels and institutionalfacilities. For each case study, a thermal and moisture diffusion analysis is conducted to evaluate the thermal effectiveness of the proposed envelope design and to assess the potential of surface or interstitial condensation within the layers. Different scenarios are also simulated under various climatic conditionsduring the year and even during a single day to determine the operational behavior of the assembly, the optimal ordering of the assembly layers, the need of some features within the envelope such as vapor barrier and several other critical issues.
