This thesis investigates the structure of the College of Architecture and Planning (CAP) at Ball State University, otherwise referred to as the Architecture Building (AB). The purpose of this study was to examine the use of energy within the two wings of the building. The research focussed on the history of the decision-making process of the design. It studied the geometry of the building. It researches the issue of lighting and daylighting. It examined the behavior of the HVAC systems. It studied the current and potential use of the Solar Chimney. It analyzed the existing windows as well as possible alternatives.The study results in an experimental design for an additional wing for the Architecture Building. It also recommends specific solutions for optimizing the separate parts of the existing building with respect to their use of energy as well as their exposure to daylight. This also helps to identify the limits of rebuilding an existing structure. Therefore, the appendices show new technologies that will help future designs, from the building materials used to the change of the design process itself.With its huge south-facing atrium and the closed north wall this building communicates the idea of utilizing natural energy sources (e.g., maximizing of solar gain) and minimizing the loss of energy through the building envelope.In fact, the biggest energy consuming factor is not the loss of energy during the winter time, but the excessive gain of energy during the summer which puts an extraordinary cooling load on the A/C system of the building. Apart from that, the amount of electricity for lighting due to the unavailability of daylight as well as the very inefficient lighting system and fans of the A/C system is extensive.Recent advances in the development of high efficiency windows and lights would allow for significant savings within the building. Unfortunately, a lot of the problems of the building are "cast in concrete" and therefore cannot be changed. This leads to the realization that architects need tools that allow them to better predict the future behavior of their anticipated structures. New developments in the field of Computer Aided Design (CAD) boost this simulation ability of planned buildings to a point unthought of a few years ago.
