“…In the following review, a special focus is given to horizontal duct systems. Just recently, Mesloub et al [13] published a feasibility study on the potential for visual comfort, overall energy consumption and the economic feasibility of tubular daylighting systems in deep plan offices in the MENA countries. This work also includes a keyword-based bibliometric analysis to extract relevant publications and research done on tubular daylighting in the period of 2010 -April 2022.…”

There are various ways of directing daylight into the interior of a building or a room. In cooperation with BASF, Bartenbach has developed a prototype of a horizontal daylight duct integrated into the suspended ceiling that efficiently transports daylight from the outside into the underexposed “core” of a building. “Skynative” is the name of the system, named after BASF spin-off Skynative® UG, which is working on market integration as well as continuous improvement of the system in an open research collaboration with Bartenbach. In this paper, the system concept development, simulation-based application studies as well as the setup of a real-scale mock-up, including results from a long-term performance monitoring at the premises at Bartenbach, are presented. First potential application projects are shown, and the system efficiency is discussed.

This research aims to analyze the environmental conditions inside and outside the Statiko Coffee Shop, Wonosobo, Indonesia, with a focus on noise, light intensity, air temperature, and humidity. Measurements were carried out at certain time intervals starting from 15:00 to 23:00. The collected data shows significant variations in each observed parameter. Indoors, noise levels varied, light intensity was recorded, air temperature fluctuated, and humidity ranged from 78.0% to 85.0%. Outdoors wider variations in noise, light intensity, air temperature, and humidity were seen. The results of this research show the importance of good understanding and design regarding ventilation and environmental management to create comfort for visitors in a coffee shop. This information can be used as a basis for designing an effective ventilation system and maintaining good indoor air quality, as well as considering external environmental influences such as noise and light intensity. Further research is needed to provide more specific recommendations for optimizing the environment at the Statiko Coffee Shop, Wonosobo, Indonesia.

“…Comparing it to case B, the use of solar tube caused an additional decrease of 13.2% in energy consumption designated to artificial lighting. Mesloub et al (2023) evaluated the use of a daylight tubular system and concluded that they were capable of saving 21% of energy consumption in offices of Saudi Arabia. Nicoletti et al (2022) simulated two offices in cities from South and North Italy and found that a daylight control system could save about 26% to 48% of energy consumption.…”

The increase of energy consumption in the building sector has been studied intensively in order to improve the scenario before the population growth and urbanisation. The lighting systems, largely used in any kind of building, are responsible for most of the energy consumption in the sector. To estimate the potential energy savings associated with strategies that explore the use of daylight, several methods can be used. The field evaluation is the one with the most precise results, however, in developing countries it may not be the best option due to the limited technologies and high costs. Given the importance of energy efficiency in the building sector, this paper aims to develop a framework based on field measurements and simulations to evaluate the potential for energy savings associated with the utilisation of natural lighting and dimming the artificial system. Days for analysis were selected based on the Clearness Index and data collection following the Brazilian regulations. The software eQUEST and DIALux were used to estimate the energy savings. Compared to the base case, the use of natural lighting and dimming the artificial lighting system allowed a reduction of 15.9% in the annual energy consumption.
