It is found that employ some advanced technology and strengthen the managements can effectively reduce the energy consumption.
Although the purchase cost for these advanced plants is great, the operating cost is small.
Besides employing above advanced technology, the marine engineers also should strengthen managements to save energy.
The purchase expense of these advanced plants is great.
However, the air-conditioning system employing the advanced technology has a better economic gain in the long run.

Preface
The 2nd international conference on Structural and Physical Aspects of Civil Engineering
(SPACE-2013) was held in High Tatras, in November 27 - 29, 2013.
The conference was organised by Department of Structural Mechanics, Institute of Structural Engineering, Civil Engineering Faculty, Technical University of Košice, Slovakia in cooperation with Slovak Society of Mechanics, Slovak Academy of Science, Bratislava.
The main objective of the conference is to bring together researchers and engineers devoting their work to structural and physical problems in different areas of engineering applications on a common platform.
The conference objectives were the following: Static and dynamic analysis of structures Seismic and stability problems of structures Experimental analysis and diagnostics of structures Resistance, durability and reliability of structures Optimization of structures Numerical methods, simulations and mathematical applications Failure, damage and reconstructions of structures We strongly believe that SPACE-2013 will have a significant impact on the development of contemporary analytical, numerical and experimental methods in structural and physical problems, and will also create an opportunity for opening a forum for discussion and collaboration amongst the participants.
This special Issue of the Advanced Material Research Journal contains the selected papers presented in the topic of the conference on Structural and Physical Aspects of Civil Engineering.
