Green lighting technology has the advantages of energy efficiency, friendly environment, safety and comfort. Based on the introduction of green lighting technology, taken the Mt. Lushan West Sea tourist highway service as the case study, we analyzed light guide illumination, the optimum use of natural light and energy efficient lighting respectively from the aspects of technical characteristics and the specific highway service application. We finally made the economic analysis in the energy savings of green lights in the highway service, and the result showed that through the use of green lighting systems Mt. Lushan West Sea tourist highway service could save electricity and reduce operating costs 134,700 Yuan per year.

And Performance

It has been observed that inefficient buildings consume three to five times more energy than efficient buildings. Subsequently, improving the Energy Efficiency (EE) of existing buildings, which account for a significant portion of the energy consumption of the building sector, has become a top priority. Also, Heating, Ventilation, and Air Conditioning (HVAC) and lighting systems typically account for three-quarters of a building's energy consumption. Hence, focus on the energy efficiency improvements associated with these subsystems is entailed to optimise the energy use of buildings in comparison to other energy consumers. Energy Retrofit (ER) is defined as the main approach in improving the energy efficiency of buildings to achieve energy reduction goals. Nevertheless, there is a general lack of awareness regarding ER. Thus, the purpose of this article is to bridge this research gap by critically reviewing the applicable literature on ER. The paper first analysed the role of retrofits in buildings concerning optimising energy performance. The paper also discusses the implementation process of ER, which includes five steps viz. pre-retrofit survey, energy auditing, and performance assessment, identification of suitable and feasible retrofit options, site implementation and commissioning, and validation and verification. Further, different types of ER applicable to HVAC and lighting systems are discussed. In their endeavor to enhance the EE of existing buildings, practitioners could apply the findings of this study, as a basis to understand the available ER types and as a measure to gauge the efficiency of existing buildings, which will facilitate effective decision-making.

The article presents the main problems of street lighting associated with the presence of large volumes of electricity losses, which are the reason for its irrational use. A method for solving these problems through the use of energy service contracts is described. The possibility of implementing these contracts together with state support mechanisms is considered, which allows for an integrated approach to achieve the main goals of modernizing street lighting systems aimed at ensuring energy conservation and improving energy efficiency. The results of the application of this approach are presented on the example of the Smolensk region, which justify the feasibility of its use.

The development of technologies associated with energy efficiency and use in lighting systems, arise as problems in the application of smart devices in different places such as: houses, buildings, industries, companies and public and private institutions. The objective of the study was to validate the instrument and the information obtained on the use of intelligent devices such as automatic control in a lighting system and its improvement in energy efficiency in the public sector. As a research methodology, a field study was conducted, based on a survey applied to 231 employees (bosses and workers) who work in 17 public institutions located in 6 cantons of the province of Manabí, Republic of Ecuador. To validate this instrument, an exploratory and confirmatory factorial analysis of the data obtained was carried out. As a result of the principal component analysis, a factor transformation matrix (0.870) was obtained and the reliability analysis was obtained (0.880) in relation to the reagents that describe three dimensions established in knowledge, application and technology management. It is concluded that the factor analysis applied through the KMO test, Bartlett's sphericity and Cronbach's alpha coefficient, with a correlation range ≥ 0.5 between reactants was feasible, which allows to certify the reliability and validity applied in this instrument.

The paper presents two ways of using the solar radiation to limit consumption of the electric power for lighting, i.e., increasing the energy efficiency of lighting systems. The solar radiation energy is a generally available type of renewable energy that to a large extent may influence a reduction in consumption of the electric power for lighting. Facilities designers and architects aim at ensuring the highest possible availability of natural lighting in rooms. Usually, lighting systems are not provided with an appropriate control system using the solar radiation. A lack of means for a correct control of the artificial lighting intensity is a factor hindering an improvement of the energy efficiency of the lighting systems. Implementation of the correct control system is possible when distribution of the lighting intensity in a room is known. The studies conducted in this area are a valuable source of information which can be used to develop control algorithms or determine optimum locations and parameters for installation of lighting fixtures. The second way for improving the energy efficiency of the lighting systems is a use of the solar radiation energy converted to the electric power to supply lighting systems.

KUBIK is aimed to the development of new concepts, products and services to improve the energy efficiency of buildings. The main characteristic of KUBIK is the capability to built realistic scenarios to analyse the energy efficiency obtained from the holistic interaction of the constructive solution for the envelope, the intelligent management of the climatisation and lighting systems and the supply from renewable energy sources. The R&D infrastructure consists of a building able to provide up to 500 m2 distributed in an underground floor, a ground floor and up to two storeys; the main dimensions are 10,00 m. width x 10,00 m. length x 10,00 meter high (plus and underground floor 3,00 m. depth). The supply of energy is based on the combination of conventional and renewable energy (geothermic, solar and wind). In addition, the building is equipped with a monitoring and control system which provides the necessary information for the R&D activities. KUBIK's main structure provides an experimental, adaptable and reconfigurable infrastructure to create the indoor environments to analyse and to allow the assembly of the constructive solutions for the envelope, floors and partitions which performance must to be assessed under realistic conditions.
