C.Y. Show, D. M. Sander, and G. T. Tamura developed a test method to measure the air leakage characteristics of exterior walls of buildings that utilized an outdoor sir supply system of ventilation and air handling, taking into account the influence of the stack effect. They applied this method to eight tall buildings in Ottawa, and results were reported. However, windows and wall constructions in Japan are so different than those in Canada that those results cannot be used directly. To obtain our own data, the authors developed a simple test method that utilizes buoyancy caused by the stack effect instead of fans for pressurization. To open doors on the ground floor or the window at the bottom part of the building while the stack effect is operative is the same as pressurizing the whole building, and to open an exit door at the roof or the window at the upper part of the building is the same as decompressing the whole building. This method was applied to three tall buildings of Sendai and Tokyo, whose walls were cast-in-place concrete (Building A), precast concrete panel (Building B), and metal panel (Building C). For the test results, infiltration rates through the exterior wall were estimated by approximate calculation. Of the three, it was found that Building A was the tightest and Building C was the loosest. This paper reports the results of the application for the simple test method we developed.

Wind increases the external pressure on windward walls, and decreases it on side and leeward walls. The walls have leakage paths through which air flows either in or out, depending on whether the internal pressure is lower or higher than the external pressure. Internal pressure adjusts to make inflow equal outflow, and depends on the size and location of large openings as well as the "background" leakage and the external pressure distribution A program, originally written to compute air infiltration, was used to predict the internal pressure for a 56-story building. The analysis showed that the addition of a single opening the size of a typical window may cause as much as a 60 percent increase in the time-averaged maximum cladding pressure, by transferring load from the leeward and side walls to the windward wall.

Office building envelopes are generally successful in meeting a range of structural, aesthetic and thermal requirements. However, poor thermal envelope performance will occur when there are discontinuities in the envelope insulation and air barrier systems, such as thermal bridges and air leakage sites. These discontinuities result from designs that do not adequately account for heat, air and moisture transmission, with many thermal defects being associated with inappropriate or inadequate detailing of the connections of envelope components. Despite the existence of these thermal envelope performance problems, information is available to design and construct envelopes that do perform well. In order to close the gap between available knowledge and current practice, the Public Buildings Service of the General Services Administration has entered into an interagency agreement with the Center for Building Technology of the National Institute of Standards and Technology to develop thermal envelope design guidelines for federal office buildings. The goal of this project is to transfer the knowledge on thermal envelope design and performance from the building research, design and construction communities into a form that will be used by building design professionals. This report describes the NIST/GSA envelope design guidelines development at the end of the first year of effort on the project. The effort to this point has consisted of a literature review of research results and technical information on thermal envelope performance and design, an assessment of existing design guidelines as they relate to the thermal envelope, and the development of a format and outline for the design guidelines.
