CONCLUSIONS
In conclusion the emergence of Zero Energy Buildings (ZEB), demonstrates the effectiveness of PD and has led to new legislative directives, such as the 2002 Energy Performance of Buildings Directive [21]. Similar targets have been established in the UK which will see ‘net- zero’ energy consumption in buildings achieved by 2016 [22], signifying the intention of the architectural industry to reduce consumption through the implementation of PD. Similarly within the marine industry the emergence of new design directives such as EEDI have stimulated the evolution of new technologies to reduce energy consumption and emissions. Considering the similarity in energy profile of both buildings and vessels, with HVAC systems contributing to the greatest amount of energy consumption (auxiliary loads). The marine industry could benefit from
from these developments by integrating TOIs architecture that has
relatively advanced technological solutions to support passive design.

Natural lighting can work well with natural ventilation as shown in Figure. 9. It helps to reduce heat gain which can be significant addition to the cooling load when using traditional filament or halogen lights. Natural lighting is a low-tech means of reducing the overall energy consumption of a vessel. It is still a developing field but as identified in Figure 3, the energy profile could be significantly reduced with the use of advanced LED technology and natural lighting systems to reduce the overall energy footprint of a vessel.
The stochastic nature of driving forces involved with PD raise an issue of reliability. However, with epidemiological
studies suggesting that PD would
otherwise improve the users comfort and wellbeing, coupled with the associated energy saving benefits and a convenient morphology that in some cases facilitates PD technology. A hybrid of natural and mechanical systems would provide a suitable solution to the future legislative pressures of
energy consumption within the marine
industry. There
needs to be an to assist appreciation for energy
consumption as a consequence of external and internal design morphology. On this basis there is a need for a design tool
designers in understanding the
implications of design on cooling load. Allowing it to be a consideration at early stages of the design workflow. The design proposals in this paper which demonstrate the use of natural energy flows from the wind and sun are hypothetical development using benchmarking of passive design research and empirical methods. They are part of an ongoing
programme of research at Coventry
University to develop passive design validation models and design tools, for incorporation within the marine design work flow.
