The Cost

The light emitting diode (LED) street lighting systems based on solar photovoltaic technology have been used for some time. In this paper, we present an analysis aiming at assessing the feasibility and economic performance of a solar-powered street lighting system for a 1km road. The present study introduces the architecture of a classical solar-powered LED street lighting system and estimates the total investment cost for a 1 km highway with 2 lanes. The cost comparison of solar-powered LED lighting and sodium lamps using grid was carried out. The calculations show that the energy saving effect of solar-powered LED lighting systems is obvious but the initial investment of solar-powered LED systems is more than sodium lighting systems using grid. The investment cycle is about 2.2 years under the current conditions.

Matter Element Model

In recent years, with the rapid increase of tunnel percentage in Midwestern highway construction, the tunnel operation cost rise quickly. In the cost, energy consumption of tunnel ventilation and illumination occupies a great proportion. In order to realize energy-saving and emission-reduction, there have been some new ventilation technology, for instance, the improved ventilation device, the improved ventilation method, and some new ventilation control technology. However after some new technology was applied, the phenomenon of energy-saving but not money-saving appeared. For the scientific and objective evaluation of highway tunnel ventilation technology energy-saving effect, construct evaluation index system from the three dimensions of technology usability, economy, and application effect, and then evaluate the energy-saving effect based on matter-element model. The result of assessment will give decision support for the later selection of highway tunnel ventilation technology proposal.

This paper reports the result of an investigation on the potential energy saving of the lighting systems at selected buildings of the Universiti Tenaga Nasional. The scope of this project includes evaluation of the lighting system in the Library, Admin Building, College of Engineering, College of Information Technology, Apartments, and COE Food court of the university. The main objectives of this project are to design the proper retrofit scenario and to calculate the potential electricity saving, the payback period, and the potential environmental benefits. In this survey the policy for retrofitting the old lighting system with the new energy saving LEDs starts with 10% for the first year and continues constantly for 10 years until all the lighting systems have been replaced. The result of the life cycle analysis reveals that after four years, the selected buildings will bring profit for the investment.

Because of the energy crisis and the low proportion of new buildings in Taiwan, rational use of electricity in existing buildings becomes very important for reducing carbon emissions and combating global climate change. The retrofitting of lighting systems is one of the most widely adopted energy saving measures. This study presents the potential energy saving and payback period of lighting system retrofit through replacing low performance T8 fluorescents with T5 fluorescents and LED indicator lights in the Green Building Renovation Plan. Based on the analysis, this study concludes that lighting system retrofit can achieve significant energy saving ratios of 10-17.5% in daily use. However, the average payback periods of GBRP investment and normal purchase investment are ten years and 7.82 years, respectively. Both exceed the average lifetime of lighting equipment, suggesting that lighting system retrofit is slightly uneconomical because of the low electricity tariff in Taiwan.

The idea of smart lighting has emerged over the years in commercial and industrial environments, with a focus on energy saving. With the advancement in technology, smart lighting can now offer opportunities in addition to energy saving to users in home environments for the provision of a comfortable atmosphere and the maintenance of user well-being. Currently, research in the smart lighting field is predominantly dedicated to energy saving in non-residential environments; meanwhile, the residential environments have not been explored. Therefore, a literature review was conducted to provide an overview of smart lighting systems’ effect on energy and well-being in the residential environment. Current research is mostly limited to designing and developing a smart lighting system in a controlled environment, with a limited evaluation of well-being and comfort. The review shows that residential smart lighting application possibilities and opportunities are not widely and thoroughly explored.
