DEVELOPMENT OF INTERIOR DESIGN STRATEGIES AS AN INTEGRAL PART OF A MARINE PASSIVE DESIGN METHODOLOGY FOR PASSENGER VESSELS OPERATING WITHIN THE MEDITERRANEAN

摘要

Developments in design codes within the architectural industry such as the EN 12464-1 (2011) and recent amendments to the 2012 Society of Light and Lighting (SLL); code for lighting guidelines, signify the industries acknowledgment of the importance of passive design elements, such as room surface reflectance's on the illumination of the visual environment and energy conservation. Associated research into the integrative effects of window apertures, glazing technology and lighting strategies of buildings, indicates that whole systems thinking identifies connections between components that can significantly increase resource efficiency. This is a potential area for transfer of innovation to the marine industry, with the objective of reducing electrical lighting load through an interior design process involving a parametric design methodology, informed by natural lighting. This paper presents a study that focuses on the development of key passenger zones, namely the cabins, lounge and dining areas. Surface reflectance, room geometry and glazing type were varied in accordance with natural lighting principles, in an effort to maximize daylight utilization and reduce electrical loads. Thermal contributions of solar gain and the impacts of varying occupant densities were considered simultaneously in the overall energy assessment. A series of interior design proposals are presented that adopt these strategies to identify the potential gains and barriers to their implementation. Analysis of the results shows the potential of an integrative design process driven by daylight optimization to reduce operational costs. The predicted energy savings for a range of ship itineraries operating in the Mediterranean are discussed.
