“…A so-called 'demand curve' can be created, which provides which quality and quantity of light exposure are required for human health, wellbeing, and comfort. Additionally, lighting technology that regulates the use of electric light only when needed will save energy (e.g., Mead, 2008, Hafezparast-Moadab et al, 2021.…”

Building Information Management (BIM) and Digital Twin (DT) technology can optimise lighting to support human health and well-being and the building’s energy performance. The data exchange between a physical and virtual environment was investigated, focusing on a scenario in which optimal interaction between daylight and electric light derives an optimised realisation of a given light demand curve. Investigation and validation of a DT model were done using a virtual room simulated in DIALux Evo and its physical twin for three levels of geometrical complexity. The results show the influence of model complexity and consequences on the speed of information exchange.

“…It recommended that laboratory lighting be optimal and follow standards. Optimizing lighting can be carried out by changing the furniture and lamp layouts [4], replacing the type of lamp [5], to installing smart lighting control [6]. The research about SCWB in the lighting scope has been studied, but the research used TL lamps [7].…”

Lighting is one of the crucial experiment factors in the laboratory. Laboratory’s lighting system that follows the Indonesian National Standard (SNI) can improve visual comfort during experiments. This research aims to determine the effect of strong column weak beam (SCWB) on illuminance in the laboratory according to SNI 6197:2011. The results were expected to provide recommendations for the implementation of SCWB in the laboratory so that the laboratory lighting system was more optimal. Digital Electronics Laboratory, E8 Building, Universitas Negeri Semarang had dimensions of 12m x 7m x 4m. The measurement of illuminance used general measurement and task measurements according to SNI 7062-2019. Illuminance data retrieval was carried out in two ways, namely observation and simulation. Measurement of laboratory’s illuminance by observation has been carried out for 10 days with repetition 10 times. The simulation of illuminance measurement used Dialux 10. Based on the results of observations and simulations, it can be seen that the Digital Electronics Laboratory did not follow SNI 6197:2011 with an illuminance of 31.3 – 137 lux. The simulation used the modifying lamp layout and applying TL LED (Philips Master LEDTube HO) so that the illuminance distribution of the Digital Electronics Laboratory followed SNI 6197: 2011 of 500 – 769 lux. The simulation results of the SCWB dimension variation showed that the recommended thickness of the SCWB was between 10 cm – 30 cm to obtain a more optimal illuminance.

“…A typically assisted workflow by Building Information Modeling (BIM) process is the building performance evaluation [1], for instance, for energy consumption [2] and lighting [3], and air quality through simulations [4]. The optimal building performance can be achieved with technical considerations and a close fit between the building and its users' needs, providing comfort, health, and safety [5].…”

“…In terms of a computer-aided approach, development toward an easy-to-use data input is emerging for human behaviour regarding the programming and design phase. For improving design, a variety of quantitative approaches surfaced, like the probabilistic method [6], which reflects variation in the energy consumption models and the agent-based model (see, e.g., in [2,7,8]) that is investigating complex systems composed of interacting agents. In connection to building performance evaluation, a knowledge-oriented value generation process [1,7] in which stakeholders find satisfactory proofs, concerning key performance indicators (KPIs), treated like evidence for reasoning their needs and activities had surfaced.…”

There is increasing pressure from developers toward architects and engineers to deliver scientifically sound proposals for often complex and cost-intensive construction products. An increase in digitalization within the construction industry and the availability of intelligently built assets and overall sustainability make it possible to customize a construction product. This servitization of construction products is assumed to perform much preferably in satisfying stakeholders’ physical, psychological, and social needs. The degree to which these products are performing can be evaluated through an evidence index. This article aims to introduce a conceptual model of an evidence index and test it in the programming stage of a case study. The investigation follows the evidence-based design approach and renders evidence through key performance indicators in the programming stage of the building process. For testing the concept, a case study investigation was performed by simulating a novice research assistant, and the amount of evidence was collected and appraised for evidence index. The case study showed that key performance indicators of a servitized project could be evaluated on a four-point scale. The quality of the evidence index generation depended on the level of expertise the evaluator has in research and the skilful use of scientific databases.
