| dc.description.abstract | Three types of apartment claddings in Surabaya, Indonesia were studied to analyze
their effect into bedroom temperature. They were glass windows in a niche, glass door in
a balcony, and glass windows on a plain wall with glass door in a balcony. On-site temperature
measurement was recorded and complemented with questionnaire surveys of occupants’
perception regarding room temperature. The study showed that an apartment cladding with
the largest proportion of opaque material combined with a balcony offered an indoor
temperature of up to 9 °C lower than the outdoor compared to the other cladding types.
Nevertheless, 72 % of occupants participated in this study, who use air conditioners during
night time, including one with the cladding with the largest temperature difference claimed
that the indoor temperature before air-conditioners was still too warm, which triggered
air-conditioners initial time more than 10 minutes to achieve the desired indoor temperature.
It indicated that the opaque material time lag played a significant role in heating the room
during night time when the air-conditioner is about to be operated. | en_US |
