“…Furthermore, everyone inside and outside the organization can do apply this with a low investment. An elementary energy conservation plan in an appropriate system for the building based on the current evaluation and related research can be summarized as follows:  Raise awareness and campaigning to turn off lights in non-activity areas [38,39];  Reduce the number of lamps in areas where the light exceeds the set standard [40] or in areas where natural light can be used [41], which will also reduce the heat build-up due to incandescent lamps [42];  Modify the light control switch in each area or add a control switch to select the appropriate area of the room [43];  Change the size of the lamp to have lower the power, for example, a 20 W LED lamp, which is the largest may be replaced with tube lighting, such as T5 tubes;  Use pull switches in the office [44] or motion sensors [45] to have power in realtime, or sensors that detect the natural environment to control energy use [46];  Use an automatic on-off system during non-use periods, such as setting on-off times to be consistent with working hours and lunch breaks [47];  Replace cloudy or transparent lamp covers for the best use of the light;  Plan classroom size according to the number of learners to avoid small numbers in a large classroom.…”

Lighting systems are used in all building types and consume large amounts of energy as well as adding to carbon dioxide (CO2) emissions. The aim of this research was to analyze energy consumption in the lighting systems of a new building. This study conducted a preliminary energy consumption audit of the Faculty of Science on the Kasetsart University Sriracha Campus, Thailand. The actual energy consumption in the study period and the specific energy index (specific energy consumption) were assessed. The results showed that the total electric power of all bulbs in the building was 72.13 kW and about 74 % were 20 W lamps. Annual energy consumption and carbon dioxide emissions were 157,753.73 kWh and 89,477.92 kg carbon dioxide for 9 hours use. The total energy consumption accounted for 1.64 % and 4.37 % based on 9 and 24 hours operation, respectively. The specific energy index was higher than the average for this university. Therefore, the energy consumption data obtained are very important in developing energy-saving measures.

“…In (Kotsarenko & Ramos, 2012) An alternative approach for diffuse lighting and specular reflections is presented, and (Din, Kim, & Kim, 2013) considers an energy-efficient utilization in lighting control systems. Based on the above issues, our study, and taking the international standards into account, the design of lighting system of the Holy Shrine of MASOUMEH is very weak, and it requires the introduction of an alternative scheme that provides the intensity required by standard according to the aesthetic discussion of sacred places and energy efficiency.…”

Islamic countries have many sacred places that represent the culture, identity, and civilization of them. One of the most important tools that can improve the design and architecture of these places is the proper design of lighting systems. Using simulation results in DIALux Evo software and comparing them with lighting standards, technical and operational disadvantages of the current scheme were identified. In this paper, we propose alternative lighting schemes for the courtyard of the Holy Shrine of MASOUMEH considering standards of lighting systems and related international experiences in order to eliminate disadvantages in the current lighting system and to reduce and optimize energy consumption. The results show that proposed alternative schemes not only satisfy technical indicators and standard lighting values but also save the number of lights, the amount of energy consumption, and corresponding costs.

“…As a result, how to make such a train transport its passengers efficiently with a low Traction Energy Cost (TEC) intensity (i.e. TEC per unit transport) is extremely significant for the efficiently sustainable development of the railway transport in China, because of the importance of energy efficiency which has been receiving more and more attention for solving energy problems such as climate change [2].…”

Based on simulations of the transports of a typically formed Chinese intercity passenger train hauled respectively by major types of the locomotives on a certain railway line in China, this research analyzes the changes of the traction energy cost intensity and passenger transport efficiency of the train with varying its passenger capacity utilization rate and target speed. It is found that if the passenger capacity utilization rate of such a train is higher than 60.00%, the effect of its passenger capacity utilization rate and target speed on its traction energy cost intensity and passenger transport efficiency is relatively very small. In contrast, if the passenger capacity utilization rate of the train is reduced from 40.00%, the efficiencies of its traction energy cost and passenger transport both decrease obviously and such decreases are evidently affected by its target speed. Therefore, strictly preventing the passenger capacity utilization rate of a conventional intercity passenger train from decreasing from 40.00% in particular and meanwhile striving to make its passenger capacity utilization rate higher than 60.00% as new evaluation benchmarking are able to effectively improve the railway passenger transport operation management in China.
