Kota Lama Semarang is a historical monument also listed as a conservation area. Still, it maintains its existence throughout centuries, considered a one-in-a-million precinct condition in Indonesia. However, while it is quite a challenge to protect the remaining evidence, Kota Lama is also competing with the development of the metropolitan area of Semarang City, which lies at the perimeter of this area. Moreover, many factors support those problems, such as high-intensity circulations, practical lighting, and the unnecessary glare covering most areas. This situation threatened the site's image, the nocturnal visualization that affected most nighttime activities because of the lack of luminance. To be exact, it affects the site's ideas and values that need to be highlighted from the details of the building, articulations that lie in between, and the proper status as a heritage precinct which is the 30 Ha core area of Kota Lama Semarang. To streamline the situation, all of the problems established in Kota Lama's nighttime lighting need to be comprehensively analyzed and technically inspected to understand the exact issues. Benchmarks and precedents were also conducted during this research to measure the gap needed to be achieved in simulations, especially in luminance situations. The verdict is undeniably stager, with 90% luminance and illuminance results either dramatically below or shockingly higher than the par. It is needless to say that most of them are not applied optimally. A line of simulations was conducted with an evidence-based lighting design method to respond to the present situation, and priors to the simulation, rows of steps and data were prepared to ensure reliable results. The simulations of proper lighting are dramatically different with a pleasant tone. A unique effect was established after adequate lighting was applied to the area and corridors of Kota Lama Semarang during the simulations. Even though the simulation was successfully conducted, the verdict also needed to include the human factors, with views and vistas as tools. Based on the hypothesis, a series of development utilizing fragmental series of methods, especially in open spaces, is required to stimulate the user's sight to optimize the nighttime lighting that has already been simulated, to established the proper conceptual design of lighting quality in Kota Lama Semarang.
