Determining the awareness and knowledge of officers towards ship energy efficiency measures

Improving energy efficiency practices on ships is crucial for both economic and environmental purposes. Both technical and operational applications are made to increase energy efficiency on ships. The success of energy efficiency applications on ships depends on the effective work of seafarers. Therefore, awareness and knowledge about the energy efficiency of seafarers should be enough. The aim of the study is to determine the awareness and knowledge level of seafarers on energy efficiency on ships and to evaluate energy efficiency practices in maritime transportation companies from the perception of seafarers. In the study, the survey method was used. As a result of the survey, it was found that the knowledge level of the seafarers on ship energy efficiency was low, almost half of them did not receive energy efficiency training but they were informed about the importance of the issue. At the end of the study, it was evaluated that the awareness and knowledge level of officers should be increased in order to improve energy efficiency on ships and suggestions on this issue were determined.

Balanced Scorecards

Balanced Scorecards represent powerful management tool for describing, ex-plaining, representing and implementing different business strategies. Being in use for more than two decades, this tool proved its applicability in public, private and non-profit enterprises, which makes it suitable for applying in local development plans. The municipality of Savski Venac applied balanced scorecards as decision-making tools to structure its objectives and articulate them into the strategy. However, the energy efficiency, although perceived as a national priority, was not included in the developed municipality strategy map. This paper investigates the possibilities to integrate the energy efficiency objectives and the municipality strategic objectives, in order to identify and apply proper key performance indicators, targets and measures to improve energy efficiency in different sectors. The ultimate goal is to propose proper GHG mitigation measures to enhance energy efficiency that will fit within the local development strategy of the municipality of Savski Venac, to align the energy efficiency measures with its energy policy, to improve the selection process of the energy efficiency measures and to adjust it to the municipality needs.

Campus Building

Electric appliances for cooling and lighting are responsible for most of the increase in electricity consumption in Karachi, Pakistan. This study aims to investigate the impact of passive energy efficiency measures (PEEMs) on the potential reduction of indoor temperature and cooling energy demand of an architectural campus building (ACB) in Karachi, Pakistan. PEEMs focus on the building envelope’s design and construction, which is a key factor of influence on a building’s cooling energy demand. The existing architectural campus building was modeled using the building information modeling (BIM) software Autodesk Revit. Data related to the electricity consumption for cooling, building masses, occupancy conditions, utility bills, energy use intensity, as well as space types, were collected and analyzed to develop a virtual ACB model. The utility bill data were used to calibrate the DesignBuilder and EnergyPlus base case models of the existing ACB. The cooling energy demand was compared with different alternative building envelope compositions applied as PEEMs in the renovation of the existing exemplary ACB. Finally, cooling energy demand reduction potentials and the related potential electricity demand savings were determined. The quantification of the cooling energy demand facilitates the definition of the building’s electricity consumption benchmarks for cooling with specific technologies.
