This study identifies the significance of design elements impactinghuman performance, thereby informing green design priorities. Ohio is uniquely positioned for such a study because it has by far the largest group of green schools in the country. A statistical model was developed to analyze changes in human performance with changes in the built environment. The most notable finding was the difference in the rate of change in student performance between daylit schools and non-daylit schools designed for high indoor environmental quality. The analysis showed that among design elements impacting people, daylighting was the leading influencer of student performance. This is the first time a study has found statistically significant evidence of priority among design elements that have been proven to impact human performance.

Khartoum, the capital of the Sudan was chosen for this study because of two reasons; The first is its unusually hot-arid climate (thus cooling interior spaces becomes a crucial design consideration). and the second is its multi-dimensional urban identity. The city is a mixture of African, Arab, and European influences and resembles at the same time an oasis in the middle of the desert. The research follows two distinct but closely related paths. The first is the study and analysis of the passive and hybrid cooling systems and strategies under which the climatic conditions of Khartoum determines the type and size of each approach. The second stage of the research will focus on the architectural implications of these systems. Both directions l...

This paper provides a comprehensive analysis of the outdoor and indoor environmental conditions that occurred in July of 1995. We selected three sites in which two residents have perished which represent different architectural and urban conditions. Site climate data were synthesized using microclimate simulation. The generated climate data is then used to estimate the internal conditions. Estimated interior conditions have shown a two-day time lag between the outdoor and indoor peak heat stress. This research established that heat-related fatalities are likely to occur in extreme heat episodes if the air-conditioning fails and the residents were frail, unable, or unwilling to spend the nights elsewhere. The results also demonstrated that trees and vegetation may reduce the impact of Urban Heat Island (UHI), but will not negate the extraordinary conditions created by a heat wave.

With the promise to simplify construction, lower cost, increase speed and responsible use of natural resources, encourage recycled material use, and increase design flexibility, parametrized 3D printing represents a credible alternative to current construction practices. To date, the focus of research has been on printing techniques, materials, and structural performance, but many of the promised benefits and opportunities have remained largely unrealized. One of the topics that have received little attention is the study of the thermal performance of the 3D printed walls and envelope components. This paper describes the design and application of a small Hot B...

Content delivery of the class sequence uses Bloom's Taxonomy model to align students' learning outcomes in the ECS classes with those required of the students at their level of educational development. This integration of students' learning outcomes allows products from other classes or studios to be used in the ECS classes. Projects are designed to meet and challenge students at their various levels of development in skills, abilities, and cognitive processing. The result is an intensive sequence of classes that work in harmony with studios and other lecture classes.

Its uniqueness is a product of experiential and transformative learning practices. The question that arises is if experiential learning could be delivered in a compressed timeframe. This paper describes a five-week foundation studio that functions as an alternative path to students who were not accepted in the first admission cycle. To catch up with their peers, the students need to acquire the necessary design skills in five weeks instead of the whole semester. Due to the short time frame, the instructors could not fully implement traditional transformative and experiential design practices that based on reiteration and reflections. Since a design studio is not merely a pedagogical mode but also a formative experience, the students' own past experiences and understanding of human-body in space were used in constructivist approach through which spatial design was posited. Thus, a phenomenological approach was devised to deliver an interrelated series of exercises. The instructors collected data through interviews, in-studio observations and a qualitative survey. The students are performing well primarily by comparison with their second-year cohorts. These preliminary results demonstrate that by linking spatial design to students' familiarity with the human body in space, a viable approach to design studio pedagogy in compressed timeframes can be justified.

Presently the AEC industry continues to inform their association members, stakeholders, etc., about BIM adoption in a variety of ways. However, at the core of all this BIM evolution is education. This paper focuses on the experiences gained in introducing BIM in the comprehensive design studio at different institutions. Using BIM as a framework for evidence-based design approach, BIM was implemented as the primary design tool for the final year architectural students at KSU to develop architectural, structural, MEP design for their studio's projects. The main objective of this studio is to provide students with means through which integrative pedagogical objectives are achieved through BIM. The interoperable devices are used to measure students' understanding and successful integration of the building design, the complex relationships between its components, and the construction processes through which their ideas could be realized. This includes documenting and evaluating students handling cross-disciplinary interests through use of Building Information Modeling knowledge and other tools into their practical design project. In addition, the paper assesses potential BIM future role in the building industry based on actual case studies and lessons learned, and suggested practical approaches to integrating BIM in AEC education.

With the promise to simplify construction, lower cost, increase speed and responsible use of natural resources by incorporating recycled material, parametrized 3D printing represents a credible alternative to current construction practices. To date, the focus of research has been on printing techniques, materials, and structural performance, but many of the promised benefits and opportunities have remained largely unrealized. One of the topics that have received little attention is the study of the thermal performance of the 3D printed walls and envelope components. Unlike traditional construction materials, 3D printed building blocks can be quite complicated. Either by encapsulating variable size and configuration air gaps or embedding circulating fluids, these components tend to be small and require special handling. Conventional apparatuses used to measure the performance of conventional materials may not be suitable for these units because they are large, require large samples or building components. Due to the high cost of testing materials in commercial facilities as well as the delays in testing, small Hot boxes were introduced and studied (Seitz and Macdougall, 2015; Buratti et al., 2016). This paper describes the design and application of a small Hot Box Apparatus developed specifically to test the thermal performance of small and highly detailed samples produced in our labs. Based on several initial experiments, authors discuss in detail the testing procedures, the instrumentation, and the conditions of the tests. The discussion includes errors encountered and elaborates on their sources and how we addressed them in the two experiments that are the basis of this paper. The results revealed that the obtained values from the hotbox were within the acceptable margin of error found in similar laboratory tests. Data collected from testing a rigid polystyrene board of known thermal characteristics were used to estimate parameters used in the determination of the thermal resistivity (R-value) of the ceramic wall. Initial results the R-value of ceramic assembly were promising because of the ability to embed different shapes and sizes of air pockets in the wall. Recommendations include improving the performance of the Hotbox and instrumentation to increase the accuracy of the measurements.

Surveys have shown the public cares most about the academic success of schools. Therefore, the impact of design decisions on student performance should be understood. Research has established lighting, indoor air quality and thermal comfort as the building design elements influencing human performance. The goal of this research was to identify through statistical analysis any significance or priority among design elements influencing academic performance. Ohio is uniquely positioned for such research because it has by far the largest group of green schools in the country (over 250). The analysis found that daylighting influences student performance in the short term. This study represents a significant support to the growing body of evidence that links improvement of indoor environmental quality and human performance.

The first scenario assumes a continuation of existing population dispersion trends with a predominant single major urban center in Cleveland. In this case we predicted a rise in Vehicle Miles Traveled (VMT) of 34% in 2050. The second scenario that applies a multi-nodal configuration of high density residential clusters with an extensive transit system showed a marginal improvement over the first scenario. The last scenario investigated the impact of a social and economic collapse when disposable income is reduced, freeway lanes are unfit for use, and population is living close to employment clusters and incapable of traveling between centers. This scenario showed that if we do not pay serious attention to solving the problems of sprawl, it is possible that suburbia could collapse and with it the social structure we know it today.
