Art for the Elm City: Public art in New Haven, Connecticut

This dissertation identifies and investigates the development, content, placement and scope of imagery associated with the city of New Haven, Connecticut, as expressed in the medium of public art, monuments and memorials. Utilizing public art to analyze the construction of the city’s composite identity is a fresh approach to writing local history in the twenty-first century. Consisting of a narrative and a catalog of 470 works of public art, this dissertation offers insight into the conditions and sometimes competing interests that structured the production, placement and uses of public art in the context of one urban space, over the course of almost two centuries. The result is an image of a city shaped by sensitivity to place, supported by self-selected episodes from local and national history

A novel solar-geothermal trigeneration system integrating water desalination: Design, dynamic simulation and economic assessment

In this paper, an innovative solar-geothermal polygeneration system is investigated. The system supplies a small community with electricity, desalinated water and space heating and cooling through a district network. The hybrid multi-purpose plant, based on an Organic Rankine Cycle (ORC) supplied by medium-enthalpy geothermal energy and by solar energy; this latter is provided by Parabolic Trough Collectors (PTC). The geothermal brine is first used to drive the ORC loop, then to provide space heating at around 85\uf790 C (in the winter), or cooling (in the summer, by means of a single-effect absorption chiller). Finally, the geothermal brine drives a Multi-Effect Distillation (MED) system, where seawater is converted into freshwater. For such a system, a dynamic simulation model was developed in TRNSYS environment. In particular, the ORC model, developed in Engineering Equation Solver (EES), was based on zero-dimensional energy and mass balances and includes specific algorithms to evaluate the offdesign performance. Similarly, a novel model of the MED unit was developed in EES. Suitable control strategies were implemented for the optimal management of system. The energy and economic performance of the system under analysis was investigated, using different time bases (day, week, month, year). Finally, a sensitivity analysis was performed to determine the set of system, design/control parameters able to minimize the simple payback period. The results showed that the novel system is highly flexible and efficient. On the other hand, a significant capital cost must be taken into account, so that the system is economically profitable only when the majority of the energy available for heating and cooling purposes is actually used
