“…Han et al [22] reported that the control of a 200 W LED lamp and daylight exploitation could achieve savings of 174 kWh per year taking into consideration the operating conditions of the experiment. Likewise, two control algorithms were tested for the lighting of two offices, where the experiments shown savings of up to 70% [23]. In [24], three classrooms were studied over the course of a year with various types of lighting control.…”

This paper compares the potential for building energy saving of various passive and active strategies and on-site power generation through a grid-connected solar photovoltaic system (SPVS). The case study is a student welfare unit from a university campus located in the tropical climate (Aw) of Guayaquil, Ecuador. The proposed approach aims to identify the most effective energy saving strategy for building retrofit in this climate. For this purpose, we modeled the base line of the building and proposed energy saving scenarios that were evaluated independently. All building simulations were done in OpenStudio-EnergyPlus, while the on-site power generation was carried out using the Homer PRO software. Results indicated that the incorporation of daylighting controls accounted for the highest energy savings of around 20% and 14% in total building energy consumption, and cooling loads, respectively. Also, this strategy provided a reduction of about 35% and 43% in total building energy consumption, and cooling loads, respectively, when combined with triple low-e coating glazing and active measures. On the other hand, the total annual electric energy delivered by the SPVS (output power converter) was 66,590 kWh, from where 48,497 kWh was supplied to the building while the remaining electricity was injected into the grid.

“…Numerous lighting control methods, such as occupancy-based control systems, day-light-linked control systems, personal control systems, and institutional control systems, may be differentiated in addition to human control. Additionally, the top ology of this system is either open-or closed-loop [31]. Ref.…”

“…Since the beginning of modern lighting technology development, photometric measurements have been important. The measurement methods began gaining key importance when modern simulation methods, forming the basis of lighting designing and optimizing processes [1], appeared. Digitally recorded luminous intensity distributions (LID) of light sources and luminaires are the starting point of a lighting design [2,3].…”

“…Lighting has become more user-friendly, and control of luminous flux and light color has become cheap and simple. Easy and cheap lighting control options have been introduced, leading to significant energy savings [1,5,6]. However, the basic LED feature is high luminance [7], reaching the levels from several to hundreds of million cd/m 2 [8].…”

Almost all solutions in modern lighting systems are based on LED technology. Luminance and obvious ease of control are the key characteristics of this light source. At the same time, luminances at the level of 10 8 cd/m 2 are a significant advantage of LED in design applications, where high luminous intensity amplification is important. However, in general and in road lighting applications, LED luminaires represent a source of potential discomfort glare. Unfortunately, lighting technology's metrology lags behind LED parameter development and optimization. The results of luminance measurements of the same luminaires, made with a luminance camera and meters with a measuring field, differ. The differences even appear for the same imaging luminance measuring devices with different lenses. This article presents the results of experiments and detailed analyzes related to modern digital luminance photometry based on the use of digital image sensors. Luminance tests were conducted on multi-source research models of luminaires. Traditional luminance measuring equipment with a measuring field was used in the experiment. The research was also supplemented with the measurements made using CCD/CMOS luminance cameras with selected components where the angular field of view of each pixel was a 0.45 min arc corresponding to the highest average human sight parameters. The results confirm that the average luminance value for multi-source luminaires depends on the measurement system configuration. It has been proposed to standardize the angular field of view parameters of all measurement systems, where the measurement aims to obtain a value that directly relates to human visual impressions (e.g. glare).
