Net-Zero Energy Mixed-Use High Rise Design: Principles and Proposals for Two Environmental Contexts 1 will give proposals for two net-zero energy mixed-use high rises, in two contrasting climates, that supply their energy needs through the power of sun, wind, water, and earth. My research and designs will help address growing and valid concerns about rising energy prices, energy dependence, and the impact of climate change. Buildings are the primary energy consumers in the United States and most developed countries. Furthermore, the demand for mixed-use high rises continues to grow as the world population increases and urbanizes. The creation of net-zero energy mixed-use high rises by the building sector is therefore key to decreasing the developed world's energy consumption. To date, there are no net-zero energy mixed-use high rises. In order to achieve my design and research goals, 1 will first conduct an extensive literature search drawing upon scholarly resources from the Technical University of Vienna in Austria and the University of Maryland in the United States, as well as suitable internet resources. ldentified resources will be categorized and used to define net-zero energy building specifications and relevant terminology. Then, 1 will define high rise building, describe high rise building buildup, occupant's comfort in the indoor environment, before defining mixed-use high rise building. Next, 1 discuss about energy consumption in high rise buildings, thus leading to energy efficient high rise design. Here, 1 introduce and analyze passive design strategies and sustainable technologies, presenting them through high rises all around the world. Later, 1 will conduct case studies, analyzing the development of exceptional sustainable high rises. The case studies will provide useful principles, guidelines, and technologies for my final design proposals. 1 will then identify two varying and distinct environmental climates to serve as sites for the design of mixed-use high rise buildings projected to achieve net-zero energy. The two contrasting climates will determine the parameters for the testing of my design concepts, resulting in unique designs for each climate. 1 will use the learned principles for the proposals of the two net-zero energy mixed-use high rises, one design for each contrasting climate, that supply their energy needs through the power of sun, wind, water, and earth. My thesis research will result in a set of practical principles and cutting-edge technologies for application in net-zero energy high rise designs in two distinct climates. 1 will collaborate with my professors in the United States and Austria to write an article for submission to a journal in the field documenting my research and analysis.
