The central idea of the 2005 Virginia Tech Solar House was to celebrate its solar aspects while integrating the engineering systems and the architecture into a single entity. Through the process of design and construction, the relationship between each detail and the overall architectural concept became evident. Highlighting four specific details to illustrate such intimate relationship, this study shows the importance of carefully working through each detail to remain faithful to the original design without any major compromise. / Master of Architecture

There is no primacy to Architecture. For centuries architects have posited formulaic approaches to creating spatial environments. Bold maxims for design have defined entire periods and styles of architecture, and each subsequent postulation attempts to disprove the former by challenging its theories against imperfect realizations. Yet nearly all have the same fault; they prioritize characteristics of architecture, attempting to design according to absolutisms of thought and process. I believe this to be a dangerous mode of operation, as absolutisms can be extremely complex and difficult to grasp conceptually, let alone to manifest into realities. Reducing architecture to processes of selection, generalization, singularities, and priorities is just clever ways of dealing with complexity in an attempt to make the intangible tangible. This "reduction" and "simplification" can only hold value as a tool for the study and analysis of architecture, not its practice and execution. Although architecture is universally conditional, it has been assigned universal qualities over time in theory and practice. I believe time requires that those qualities be subject to change and reinterpretation so that architecture may maintain proper relevance, barring one constant: all qualities must exist by virtue of the others and cannot be seen independently; one quality is no more than an aspect of the others. To better explore this notion, three criteria (qualities, generators) have been identified as a measure for critical analysis of three architectural research projects. They are built from a history of pre-defined criterion, named and redefined in an attempt to elevate a personal study and practice of architecture at a period in time. These projects have a high degree of personal influence and involvement, and so this becomes in a way a self-analysis in the study and practice of architecture. The intention of this compendium is to gain insight towards a personal definition of architecture through an analysis of architectural theory and precedence in comparison to work that is reflective of personal architectonics. In time, I hope it will have continued to develop. / Master of Architecture

Zero energy houses and (near) zero energy buildings are among the most ambitious targets of society moving towards an energy efficient built environment. The "zero" energy consumption is most often judged on a yearly basis and should thus be interpreted as yearly net zero energy. The fully self sustainable, i.e. off-grid, home poses a major challenge due to the dynamic nature of building load profiles, ambient weather condition and occupant needs. In current practice, the off-grid status is accomplishable only by relying on backup generators or utilizing a large energy storage system. The research develops a risk based holistic system design method to guarantee a match between onsite sustainable energy generation and energy demand of systems and occupants. Energy self-sufficiency is the essential constraint that drives the design process. It starts with information collection of occupants' need in terms of life style, risk perception, and budget planning. These inputs are stated as probabilistic risk constraints that are applied during design evolution. Risk expressions are developed based on the relationships between power unavailability criteria and "damages" as perceived by occupants. A power reliability assessment algorithm is developed to aggregate the system underperformance causes and estimate all possible power availability outcomes of an off-grid house design. Based on these foundations, the design problem of an off-grid house is formulated as a stochastic programming problem with probabilistic constraints. The results show that inherent risks in weather patterns dominate the risk level of off-grid houses if current power unavailability criteria are used. It is concluded that a realistic and economic design of an off-grid house can only be achieved after an appropriate design weather file is developed for risk conscious design methods. The second stage of the research deals with the potential risk mitigation when an intelligent energy management system is installed. A stochastic model based predictive controller is implemented to manage energy allocation to sub individual functions in the off-grid house during operation. The controller determines in real time the priority of energy consuming activities and functions. The re-evaluation of the risk indices show that the proposed controller helps occupants to reduce damages related to power unavailability, and increase thermal comfort performance of the house. The research provides a risk oriented view on the energy self-sufficiency of off-grid solar houses. Uncertainty analysis is used to verify the match between onsite sustainable energy supply and demand under dynamic ambient conditions in a manner that reveals the risks induced by the fact that new technologies may not perform as well as expected. Furthermore, taking occupants' needs based on their risk perception as constraints in design evolution provides better guarantees for right sized system design.
