The development of products which enable passive solar-energy air-heating to be integrated into the heating strategies of public, commercial and industrial buildings is described. These buildings are, in general, only occupied significantly during the day; consequently the bulk of heating demand coincides with the period of solar gain. In these circumstances collected solar heat should be delivered with the minimum of delay. The design and operation of units which are capable of supplying solar heated air in this manner is outlined. These are passive, naturalcirculation air-heating collectors, also known as natural-convection air-heaters, or thermosyphoning air panels. Four methods of retrofitting such solar collectors to non-domestic buildings have been identified, one of which, the overcladding collector, has not been proposed previously. Problems associated with the successful installation and operation of these units have also been considered. The relative merits of a number of methods of testing passive solarenergy air-heating collectors have been investigated. A method of determining instantaneous collector efficiency based on the measurement of glazing temperature, inlet and outlet air temperature, ambient temperature and insolation has been developed. Three novel design proposals have been presented: i) a collector constructed with the insulation fitted outside, rather than inside, so that the metal body of the collector may provide more symmetrical heating of the air flow than the conventional arrangement, ii) an absorber which consisted of parallel ducts to increase the rate of heat transfer to the air, heating it symmetrically, (iii) a hinged air-deflector for conversion from the heating to the ventilation mode.

Thermal efficiency of Precast Concrete Sandwich Panel Walls has become a major topic when discussing the building envelope in academia. At Utah State University, research is being done to evaluate the structural and thermal efficiency of fiber reinforced polymer connectors being used today. In evaluating several different proprietary fiber reinforced polymer systems, researchers plan to develop design procedures to help engineers accurately determine minimum design requirements when using fiber reinforced polymer connectors. This largely requires a determination of the degree of composite action incurred by each system. Testing is performed by constructing small scale specimens (3 ft. by 4 ft., 0.91 m by 1.22 m). Each specimen contains one of the fiber reinforced polymer connecting systems. By constructing a five-wythe, two wall specimen, direct shear can be applied to the connectors using a push-off shear test method. By performing this test it can be determined to what degree the panel is acting compositely. Once the degree of composite action is determined, correlation can be made between design and degree of composite action. Economizing and simplifying this procedure is key to further implementation of precast concrete sandwich panel walls in all areas of our building infrastructure.

Thank you. / This publication is the discussion and examination of work produced for the degree of Masters of Fine Arts in enameling and metal work. The body of work created consists of enameled brooches and wall panels. The thesis paper documents the technical and aesthetic developments in painting and metals as they pertain to the thesis work, and discusses the landscape subjects which so strongly influence the images that I create. The work produced for the thesis show is discussed in the manner in which it was conceived, as groupings; or as series. Methods of manipulating enamels for specific visual and textural results, various enamel finishes, and the use of enamel oxides are documented. Metal techniques employed as well as the framing method devised for the presentation of the wall panels are also documented. References and key incluences are painters and artists working in metalsmithing and jewelry. In the painting field Narcisse Diaz, Charles-Francois Daubigny, Eduard Vuillard and George Inness are nineteenth century artists who greatly influenced my artistic development. In the metals field Charles Loloma, Georg Jensen and Rene Lalique are influences which established the foundations of my ideas and tastes in my jewelry . While at graduate school the work and teachings of enamelists Jamie Bennett and William Hellwig initiated the interests I developed for enameling. The paper is essentially an indepth analysis of the way in which I perceive my work, what I want to communicate to the viewer, and how and why I create the kinds of objects that I do. / 2999-01-01

Master of Science / Department of Architectural Engineering and Construction Science / Kimberly W. Kramer / Soils conditions vary throughout the United States and effect the behavior of the foundation system for building structures. The structural engineer needs to design a foundation system for a superstructure that is compatible with the soil conditions present at the site. Foundation systems can be classified as shallow and deep, and behave differently with different soils. Shallow foundation systems are typically used on sites with stiff soils, such as compacted sands or firm silts. Deep foundation systems are typically used on sites with soft soils, such as loose sands and expansive clays. A parametric study is performed within this report analyzing tilt-up concrete structures in Dallas, Texas, Denver, Colorado, and Kansas City, Missouri to determine the most economical tilt-up wall panel and foundation support system. These three locations represent a broad region within the Midwest of low-seismic activity, enabling the use of Ordinary Precast Wall Panels for the lateral force resisting system. Tilt-up wall panels are slender load-bearing walls constructed of reinforced concrete, cast on site, and lifted into their final position. Both a 32 ft (9.75 m) and 40 ft (12 m) tilt-up wall panel height are designed on three foundation systems: spread footings, continuous footings, and drilled piers. These two wall heights are typical for single-story or two-story structures and industrial warehouse projects. Spread footings and continuous footings are shallow foundation systems and drilled piers are a deep foundation system. Dallas and Denver both have vast presence of expansive soils while Kansas City has more abundant stiff soils. The analysis procedure used for the design of the tilt-up wall panels is the Alternative Design of Slender Walls in the American Concrete Institute standard ACI 318-05 Building Code and Commentary Section 14.8. Tilt-up wall panel design is typically controlled by lateral instability as a result from lateral loads combining with the axial loads to produce secondary moments. The provisions in the Alternative Design of Slender Walls consider progressive collapse of the wall panel from the increased deflection resulting from the secondary moments. Each tilt-up wall panel type studied is designed in each of the three locations on each foundation system type and the most economical section is recommended.

Throughout their careers the Impressionists demonstrated a strong, but rarely examined, interest for decoration. A careful examination of both archival material and well-known artworks produced between 1870 and 1895 shows that Pissarro, Degas, Cézanne, Monet, Renoir, Morisot and Caillebotte never ceased to explore the values of decoration and the decorative. Set in the context of the Third Republic’s passion for monumental decoration and deep interest in the decorative arts, the Impressionists’ experiments range from ceilings to ceramic tiles, and from never achieved projects to ambitious realisations (although none remain in their original location). One painter among those surveyed also engaged with theoretical thinking: Renoir wrote for the press and drew up the drafts of a Grammar mainly focused on the decorative arts. Along with a number of artworks explicitly designated as decorative that were predominantly exhibited at the Impressionist shows, the Impressionists further produced more than twenty decorative ensembles made for the interiors of amateurs who then became patrons. Renoir, who started his career as a painter on porcelain, worked in the 1870s for the Parisian homes of a Romanian aristocrat, prince Bibesco, and of a leading publisher, Georges Charpentier, but also for the country house of Paul Berard. Monet, in a similar fashion, painted for the department store magnate Ernest Hoschedé in his property of Montgeron. Initially publicised by the painters in the 1870s, the decade on which this thesis focuses, the Impressionists’ decorative works were subsequently undertaken more quietly though continuously. Morisot painted a chimney trumeau for her own salon, to which Monet gave a pendant (they were eventually used as overdoor panels). Monet and Renoir also painted door-panels for Durand-Ruel. None of these later schemes were actually promoted towards a wide public, showing how the Impressionists’ commitment to painting decorations went from a strategic (and partly commercial) vision to embody a deeper reflection on the essence of painting and its relation to the wall – a reflection that the larger dissertation submitted to the Université de Bourgogne embraces. The critics’ attention, however, went the opposite way. It grew from a relative but highly meaningful disinterest to making the decorative key to their approach at the turn of the century, but in all situations, mocking or praising, their comments shed a crucial light on the Impressionist’s enterprises and their relations to the society’s concerns. An analysis of the Impressionists’ decorative experiments and their critical reception encourages, as this thesis aims to demonstrate, a reconsideration of our vision of Impressionism, for its development drew much more from the decorative than has so far been discussed.

This thesis chronicles my experiences with developing a panelized wall system for use by Habitat for Humanity and with testing that system in the design and construction of a house. Presented as a series of narratives, it follows the progress of the project from August 2003 to December 2005. Described is my motivation to test my theories through design and construction, the applicability of prefabrication to Habitat for Humanity’s use of unskilled volunteer labour, the incorporation of panelization into the design of a house for the Waterloo Region affiliate of Habitat for Humanity, the prefabrication of preclad wood framed wall panels for this house by students at the University of Waterloo School of Architecture, the erection of these wall panels on-site, and the completion of the house to a weathertight state. The thesis concludes with discussions of the understanding I gained through my experiences, the necessity for further development and testing of the panelized wall system, and the future use of prefabrication by Habitat for Humanity.
