The Evaluation of Thermal Comfort using a BIM-based Thermal Bridge Simulation

Abstract

Global warming has become an important issue today, caused by the increasing demand for energy and humans lifestyle. To reduce the impact, more architects started to respond regarding environmental issues. The concept of green architecture promotes to solving this problem. Natural ventilation is the one of the concept green architecture. This research tends to look at the aspect of Thermal Comfort in naturally ventilated mosque buildings through the Thermal Bridges strategy. Naturally ventilated building tend to have better indoor air quality (IAQ), but worse thermal comfort. Therefore, this research investigates the range of acceptable temperature and calculate by BIM thermal bridge simulation to achieve thermal comfort for naturally ventilated mosque building. The method of analysis conducted is quantitative based on direct measurement of weather data and existing comfort conditions in the field, calculations, and simulations using Building Information Modeling (BIM). Data was collected through a field survey in Itenas Mosque Building and were used to develop and validate then using the BIM thermal bridge model for simulation. The data collected from field survey and in situ environmental measurement such as air temperature, relative humidity, and wind velocity. The thermal comfort prediction model was developed from statistical analysis of the field survey data. Based on the result of thermal Bridge simulation using BIM software required exchange material of the existing building to achieve thermal comfort.

Implementation of the Smart Building Concept in Parahyangan Office Rental Space and Apartment Design

“…Smart Building is a building that has the ability of intelligent building and integrated green building (Rahadian & Sulistiawan, 2019) (Goldsmith, 1984). Intelligent building is related to the building capabilities to manage and control the operation of automated and integrated electronic infrastructure, including the availability of ICT services, such as telecommunications, internet, Pay TV, and other services.…”

Passive Architectural Design Solution to Enhance Thermal Comfort using Building Information Modelling (BIM) on Cafe building in Bandung

“…The software made it possible to create a virtual building model with all of the design elements, including walls, floors, roofs, doors, and windows. The model could be viewed and navigated in 3D, giving designers and clients a much clearer understanding of what the building would look like in reality [9].…”

Contemporary Architecture in Typology of Car Workshop and Showroom Buildings

“…Humans build a building or building or area that will later function for the benefit of the group or/and the public/general public. The definition of architecture itself is human work that is beneficial to humans themselves (Rahadian and Sulistiawan, 2019;Rustiandi et al, 2021). These benefits consist of benefits for the body and soul in humans in carrying out their life activities.…”
