The Study of Using the Opaque Wall Material to Manage Overall Thermal Transfer for the Heritage Hospital Façade in Bangkok

Abstract

Many hospitals in Bangkok metropolitan districts are awaken to the global warming crisis. It results that the temperature in the winter is closed to the summer. The following effect is that the old hospital buildings, are confronting the energy over consumption than ever. In particular, the old facades are needed renovation to preserve comfortable condition. However, there has a limited renovation for a heritage building such the demolition in a façade component realized the maintenance of historical building character and district conservation. This article concentrates on the study the suitable opaque material finishing for the heritage hospital façade renovation. The aim is to reduce overall thermal transfer value (OTTV) of the façade related to Thailand standard requirement of Pollution Control Department (PCD). The research scope emphasizes in the opaque material of the hospital façade. Here the ward of Sirinthorn building, within Rajavithi hospital in Bangkok is selected as a paradigm. The study method is divided in 3 phases: defining a suitable format of material installation for building conservation for the paradigm, investigating opaque materials for construction following Thai Industrial Standard, and considering material character by a trail & error method. The result is the guideline of material selection presented in 3 characters. This article offers the sample opaque material to apply for the case study in practical later.
