ABSTRACT

Colonized by the Dutch for a hundred years, Indonesia has many Dutch-style churches in its cities. The uniqueness of the churches is that they have low ventilation in the below part of side-by-side walls to penetrate air movement in buildings. This current research was conducted on two Dutch-style churches with different heights of low ventilations on their walls. The study aimed to establish correlation modeling between the height of low ventilation and thermal comfort in buildings covering Standard Effective Temperature, Predicted Mean Vote (PMV), and Predicted Percentage Dissatisfied (PPD). The methods used were referred to the ASHRAE Standard 55-2017 and statistically analyzed by using linear regression and Anova of SPSS 24. The measurements were performed at the same three devotional times at similar multiple specified measuring points inside the churches. The results showed that the church with 40 cm height ventilations had 4% higher air velocity than that with 70 cm height ventilations. For PMV, the church with 40 cm height low ventilation has a 'neutral' sensation, while the one with 70 cm height low ventilations has 'slightly cool'. The church with 40 cm height low ventilation has 72% PPD lower significantly than the other.
