UTILIZING BIM AND SIMULATION TO DOCUMENT THE HERITAGE BUILDINGS' SPACE QUALITY, CASE STUDY BLENDUK CHURCH

Abstract

Indonesia has a lot of heritage buildings that are either damaged or facing design
changes. Those damage and design changes transformed the original spatial quality
inside the building and erased a part of the history. Simulation methods have the
potential to replicate the lost spatial quality and comfort. Therefore, this study aims
to test the potential of utilizing BIM and simulation software in digital conservation
with Blenduk Church in Semarang as the case study. The data was collected through
direct field measurement to obtain the dimension and daylight intensity of Blenduk
Church. The data was used to create 3D models of Blenduk Church, the old design
and the current design, utilizing Rhino and Autodesk Revit. The 3D models are
simulated with DiaLUX to find the daylight intensity and the microclimate
surrounding the building. The data validation process includes comparing both data
that was obtained through direct measurement and simulation, then calculated the
standard deviation. By doing the data validation, it was found out that the standard
deviation is 2,8%, which indicates that the simulation software is relevant to be
utilized as a tool for digital revitalization as the deviation is still within the
acceptable tolerance limits. This research demonstrates that CAD, BIM, and
architectural simulation technologies can be used to document the space quality of
heritage buildings that have been altered or demolished. This research could
contribute as a blueprint to digital conservation that is not limited to recreating 3D
model, but also continuous research of the missing space qualities.
