A microcomputer-based program has been developed at the University of British Columbia to help fisherman and naval architects estimate fishing vessel fuel consumption. The program allows users to calculate the fuel consumption for a given fishing trip scenario. The program can then be used to calculate the return on investment of fuel saving improvements made to the vessel such as: Kort nozzle, two speed gearbox, variable-pitch propeller, and new propeller design. The program can be used for the design of small vessels such as tugs and supply vessels.

The University of British Columbia (UBC) and the British Columbia Research Incorporated (BCRI) collaborated to design a fishing vessel suitable for use on the west coast of Canada. This vessel, called the UBC Series parent hull form, was designed to have a large aft deck area and a volumetric coefficient comparable to those of modern Canadian fishing vessels. The resistance characteristics of this hull were improved without compromising on functionality and usable space. A resistance algorithm developed from the results for a systematic series of low-L/B displacement-type vessels, the UBC Series, was previously published (Calisal&McGreer, 1993). However, during the design process, the seakeeping performance of the vessel was never addressed. This paper describes the seakeeping performance of the UBC series in head seas. An algorithm, developed from the results of the model tests, can be used to calculate the seakeeping response of similar low L/B vessels. To calibrate the seakeeping measurement procedure, tank instrumentation, and data collection system, the ITTC Standard Seakeeping hull form (the S-175 hull form) was tested and the results were compared against published results for this hull form. The same techniques used for the standard hull form were then used to measure the seakeeping performance of the UBC Series. Possible application of the algorithm for non-UBC Series forms is also discussed.

Any group that creates challenging goals also requires a strategy to achieve them and a process to review and improve this strategy over time. The University of British Columbia (UBC) set ambitious campus sustainability goals, including a reduction in its greenhouse gas emissions to 33% below the 2007 level by 2015, and 100% by 2050 (UBC, 2006). The University pursued these goals through a number of specific projects (such as major district energy upgrade and a bioenergy facility) and, more generally, through a “Campus as a Living Lab” (CLL) initiative to marry industry, campus operations, and research to drive innovative solutions. The CLL program has achieved significant successes while also demonstrating many opportunities for improvements and lessons learned. The aim of this study was to examine the UBC CLL program, to identify and formalize its operations, to extract key transferable characteristics, and to propose replicable processes that other universities and municipalities can follow to expand their sustainable practices in similar ways. There was a learning curve with implementing a CLL program at UBC; thus, the goal of this study was to potentially shorten this learning curve for others. The research involved an ethnographic approach in which researchers participated in the CLL process, conducted qualitative analysis, and captured the processes through a series of business process models. The research findings are shared in two parts: 1. generalized lessons learned through key transferrable characteristics; 2. a series of generic organizational charts and business process models (BPMs) culminated with learned strategies through defined processes that illustrate what was required to create a CLL program at UBC. A generalized future improvement plan for UBC CLL programs is defined, generic BPMs about CLL projects are evaluated, and the level of engagement of multiple stakeholders through phases of project life cycle given in the conclusion for future use of other Living Lab organizations.

Standard driving cycles are usually used to compare vehicles from distinct regions, and local driving cycles reproduce more realistic conditions in specific regions. In this article, we employed a simple methodology for developing local driving cycles and subsequently performed a kinematic and energy analysis. As an application, we employed the methodology for cars and motorcycles in Recife, Brazil. The speed profile was collected using a smartphone (1 Hz) validated against a high precision global positioning system (10 Hz), presenting a mean absolute error of 3 km/h. The driving cycles were thus developed using the micro-trip method. The kinematic analysis indicated that motorcycles had a higher average speed and acceleration (32.5 km/h, 0.84 m/s2) than cars (22.6 km/h, 0.55 m/s2). As a result of the energy analysis, it was found that inertia is responsible for most of the fuel consumption for both cars (59%) and motorcycles (41%), but for motorcycles the aerodynamic drag is also relevant (36%). With regards to fuel consumption, it was found that the standard driving cycle used in Brazil (FTP-75; 2.47 MJ/km for cars and 0.84 MJ/km for motorcycles) adequately represents the driving profile for cars (2.46 MJ/km), and to a lesser extent motorcycles (0.91 MJ/km) in off-peak conditions. Finally, we evaluated the influence of the vehicle category on energy consumption, obtaining a maximum difference of 38% between a 2.0 L sports utility vehicle and a 1.0 L hatchback.

Purpose – Universities can provide a leadership role to develop and mobilize knowledge to meet societal needs. In fulfilling this mission, universities can also serve as agents of sustainable development on campus and in communities they serve. The purpose of this article is to describe the drivers that have advanced the University of British Columbia Okanagan campus' operational and academic sustainability objectives; the initiatives and partnerships developed on campus and in the community in response to these drivers; and the outcomes and lessons learned. Design/methodology/approach – This article summarizes the experience of the University of British Columbia Okanagan campus in leveraging key drivers to develop sustainability initiatives and partnerships for greater operational efficiencies, cost savings, environmental stewardship and applied research. The university's leadership commitment to sustainability, economic opportunities and provincial legislative requirements are among the drivers discussed. This paper also provides an innovative partnership framework to support sustainable community development. Findings – Drivers of sustainability in higher education can contribute to the development of sustainability initiatives and partnerships that benefit institutions and communities and achieve operational and academic sustainability mandates. Practical implications – This article provides information that can be applied by institutions of higher education to advance sustainability within the context of current economic conditions and societal needs. Originality/value – The experience of the campus and the partnership framework presented in this paper is original. The framework provides a mechanism to engage students, faculty and the community in sustainable community development research. Key insights from multiple perspectives and lessons learned are shared.
