Spaces & Flows: Ninth International Conference on Urban and ExtraUrban Studies

Abstract

Many heritage buildings in a Thai government healthcare sector are confronting a lot of electrical consumption. One of the main reasons is that heat excessively transfesr from outside, which results in mechanical and electrical system (M&E) and equipment in healthcare hospital consuming energy extravagantly during operations. The green building criteria is taken into account as the assessment method to measure heat transfer efficiently in the old healthcare building. Here adaptation in the building envelop system is considered to sustain for thermal transfer management in green building concept. This paper considers refurbishing in building envelop system for energy management in heritage hospitals by improving the building façade to reduce overall and roof thermal transference which is conformed a green building guideline. An initial goal of this research is to decrease energy consumption and promote a comfortable hospital ward zone. This project selects Sirinthorn building of Rajavithee hospital, which an inpatient ward is located, as a paradigm to analyze. The results find that envelops are adapted by changing material and some architectural details, building thermal value decrease form 91.65 watt/square meters (over the green standard) to the lower than 30 watt /square meters (followed green building standard). The research also offers the optional model for selection of material finishing and techniques. This study serves as an example of sustainable energy management by the material innovation for the sustainable healthcare heritage buildings.
