“…The process of temperature control inside the thermal test chamber was realized using a PLC controller (15) from the PC computer (14). Measurements were conducted for temperatures such as -20°C, -10°C, 0°C, +10°C, +20°C, +30°C and +40°C.…”

“…Currently, a strong demand has been observed in the field of LED sources which are commonly accepted as excellent replacements of classic light bulbs. Simultaneously with the development of LED sources, considerable interest has been noticeable also in the literature where studies of lighting and electrical parameters of LEDs have been presented, and LED-based applications have been considered [3][4][5][6][7][8][9][10][11][12][13][14][15][16][17]. From the point of view of the average consumer, the fact of strong marketing conducted by the manufacturers of LEDs, which focuses only on the advantages of these types of light sources, is also notable.…”

Abstract. This article presents considerations on the assessment of marking LED sources with the power of an equivalent light bulb. This problem was studied both on the basis of calculations and measurements performed. 17 LEDs of different powers and luminous fluxes were tested. Calculations assessing conformity with the declared power showed that an important disadvantage for most of the LED sources results from the method of marking them with the power of an equivalent light bulb from the point of view of the luminous flux emitted. Manufacturers do not do this correctly, misleading the potential user. Meanwhile, measurements performed in different ambient temperatures indicated that for only 4 from among the 13 LED sources studied the given value of the power of an equivalent light bulb may be recognized as in accordance with the actual state of affairs and still with a reservation that specified ambient temperature shall be required. In other cases the values of power quoted are either understated or overstated.

“…and building architectural-structural features and materials (e.g., constructive technologies, air conditioning systems, heating plants, exhibits, etc.) and then, their correlated and cumulative effects [4][5][6][7][8][9][10][11][12][13]. It is always possible to modify the functional and distributive use of the indoor environment of any historical building, even when it has a strong cultural, social and religious value, with the aim of sustainability and adaptive re-use [14][15][16][17].…”

“…LED lighting does not require high power, allows for the obtainment of quality light, important energy savings, quality of vision and perception, guaranteeing protection and preventive conservation. These last aspects can be obtained by modulating the luminous intensity (dimming), adjusting the luminous flux and the correlated colour temperature as well as the emission spectrum, parameterization of the illumination, rationalization of the use of light (e.g., Passive Infrared sensor, PIR, application) setting and/or recall of different and integrated lighting scenarios, setting of dynamic light/colour sequences, scheduling of choreographic events, optimization of electricity use [2,3,5,8]. All these functions are stored inside the electronic ballast, others, such as sequences and schedules, are managed by control units or software, where it is possible to adjust and customize light management, precisely from the perspective of the reuse/re-illumination strategies for historic buildings based on decision-making processes [23][24][25].…”

Natural Lighting for Sustainability of Cultural Heritage Refurbishment

Our present research, starting from a previous study, aimed to define a methodological approach for sustainable lighting designs in a historical library, focusing on lighting quality, mainly obtained from the optimal use of natural light and its combination with the artificial one. A historical Florentine monastery, which is now a university library, was used as a pilot project. The proposed method forms an essential part of widening and deepening the recent study. Results have shown that this method will allow for adaptive lighting, based on the optimal control and use of natural light, historical–philological re-reading of the space, cultural heritage preventive protection and conservation, with the aim of building adaptive reuse, and it can be extended to similar cultural heritage cases, but also non-listed buildings and current designs. This research demonstrates how a correct natural lighting design can be a tool for sustainable refurbishment, guaranteeing cultural heritage conservation and preventive protection, and recovery of the historical, architectural and philological value of old and/or listed buildings, which have been converted to uses, often diametrically opposed to the original ones.

“…Dubois et al [6] reviewed the electrical lighting retrofit to minimize energy used in buildings. They outlined lighting retrofit strategies which are: lamp, ballast and luminaires replacement, retrofits with light emitting diode (LED) lamps, retrofits with T8 and T5 lamps and reduction of maintained illuminance levels.…”

Abstract. Lighting system is an important sub-system in office buildings. A good design can contribute energy saving and visual comfort to occupants. This paper presents a comparison of lighting system design according to different standards: European Standard EN12464-1 and Malaysian Standard MS1525 in terms of average illuminance level and illuminance uniformity. In the design, the illuminance measurement is according to the Illuminating Engineering Society of North America (IESNA) and the European Standard EN12464-1. Three types of luminaires are considered which are: T8, T5 and light emitting diode (LED) lamps. The technical and economic evaluations are taken into account in this paper. The technical evaluations are considered the number of luminaires, average illuminance level and illuminance uniformity. The energy consumption (EC) and lighting energy numeric indicator (LENI) are considered according to the European Standard EN15193. Meanwhile, the economic evaluation involves billings and luminaires costs and billing savings. The case study is an office room and it is modelled and simulated using DIALux software. The results show that the design according to the European Standard EN12464-1 with uniformity based method that used T5 lamps had contributed to the highest number of luminaires and costs. Whereas, the design according to the Malaysian Standard MS1525 with illuminance level based method that used LED lamps had contributed to the lowest number of luminaires and costs. Thus it can provide the higher billing savings. It can be concluded the LED has great potential to replace T8 and T5 lamps.
