In this thesis, we develop a simulator for estimating the energy consumed in executing tasks on a mobile device - the Palm Pilot. We measured the energy consumed by each instruction of the device's assembly language and incorporated these measurements into a public domain emulator for the Palm Pilot. This emulator is cycle accurate and therefore our energy estimates for running high-level tasks is also quite accurate. We validated our simulator via a series of benchmarks where predicted and measured values of energy consumed are compared. Finally, to illustrate how the simulator can be used for energy saving purposes, different versions of a Palm Pilot cryptographic application are analyzed. / Graduation date: 2001

A computer simulation program, Controlled Atmosphere Simulation (CAS), was written in Microsoft Visual Basic 3.0, Professional Edition to evaluate energy use by three type of atmosphere generators used in fruit storage warehouses. The program consists of pulldown time and energy use models for a membrane air separator, an ammonia fractionating burner, and a catalytic oxygen burner. Predicted results subsequently became input to an interactive computer program, Fruit Storage Refrigeration Energy Simulation (FruSTRES), which was developed to simulate energy use by cold storage ammonia refrigeration systems. The resulting model package was then used to predict overall annual energy use in fruit storages, based on number and size of rooms, building construction, equipment operation (both refrigeration and CA), commodity stored, storage period(s), and weather conditions. The CAS accurately predicted the pulldown time of each type of equipment under normal operation. The resulting model package (CAS and FruSTRES), will be an invaluable tool in design and analyses of ammonia refrigeration and atmosphere generation systems used in common and controlled atmosphere fruit storages. / Graduation date: 1998

Knowledge of price responsiveness of energy is important for designing effective price-based controls to curb the GHG emissions in Canada. The translog and logit models are developed in this study to analyze the demand for four types of energy inputs: coal, electricity, natural gas and refined petroleum products in Ontario's pulp and paper industry. The results suggest that the industry is inelastic to price change of energy consumed. Tests indicate that the translog model behaves slightly better than the logit model. The translog model was then applied to study the feasibility of imposing a carbon tax on energy inputs on Ontario's pulp and paper industry, which indicated that this sector does not seem to response to changes in energy inputs prices. Therefore, a carbon tax does not seem to be a good policy option for decreasing greenhouse gas emissions in this sector.

Commercial office building occupants are a significant consumer of electricity, and they subsequently contribute a significant amount of greenhouse gases into the environment in the process. An opportunity exists to improve the energy efficiency in existing buildings, and the Energy Star certification program provides both tools to do so and an independent verification of a building's superior energy efficiency. However, only 16% of metro Atlanta's office space has achieved this certification. The intent of the research was to identify the current state of energy efficiency in buildings, and to identify potential obstacles to obtaining the Energy Star certification. Towards this goal, secondary research was conducted among prominent academic journals, as well as numerous professional and governmental organizations and publications. Primary research was conducted through an online survey of Facility Managers, Property Managers, and Building Engineers of Energy Star office buildings and comparable non-Energy Star office buildings in the metro Atlanta area. The survey was conducted mostly using closed-ended questions using a Likert scale so as to provide a basis for statistical analysis among responses, and open-ended questions were also included to identify the current state of energy efficiency practices. The research identified three areas which hold statistically significant differences between Energy Star and directly comparable buildings. An analysis also determined that building age does seem to play a role in the building representatives' responses. Four conclusions were found regarding characteristics of Energy Star buildings themselves. The research also identified five conclusions regarding the expected result when pursuing the Energy Star certification. These conclusions include the best method to achieve the Energy Star certification, the expected energy savings, the expected time spent to achieve the certification, the expected cost to achieve the certification, and the main reasons to recertify the building. Finally, this research highlights innovative practices in other states and cities, such as financial incentives and legislation which require commercial buildings to obtain a building rating. Such innovative practices are currently not employed in the Atlanta metro area, but would be beneficial to both the Atlanta area and individual buildings.
