| dc.description.abstract | As a public building that runs continuously, hospitals need a lot of energy. In
addition, the building industry in Indonesia has previously been blamed for 50% of the
sector's entire energy use, which amounts to almost 70% of all power usage. In order to
regulate and minimize energy usage, an examination of OTTV (Overall Thermal Transfer
Value) is required. Asri Medical Center in Yogyakarta will be used as the study's subject
since it mostly uses glass for its exterior and is oriented east and west, which is thought to
have a higher heat transmission. Due to this, the OTTV will be carried out to guarantee
that the building's current score does not exceed 35 W/m2 (SNI, 2011). In order to reduce
the score, a quantitative method will be used by doing modifications on the WWR, U value,
as well as a shading device. These modifications have resulted in some improvements
whereas the WWR modification can reduce the OTTV scores by 41%, and glass material
changes by 43,4%. However, there is no significant change in the shading device
modification since it only improves by 16,4% and not meeting the standard yet. | en_US |
