As prompted by the COVID-19 pandemic and the persistent issue of hospital capacity, the Philippines looked into the development of a standard modular health facility design. With access to these plans, it was possible to conduct a comprehensive quantity surveying of these recommended materials. From this, a Life Cycle Assessment (LCA) was implemented in order to identify which aspects of the plans contributed the most to their overall environmental impact. As expected, the use of concrete incurred the largest share, as observed in the structure’s flooring, foundation, and septic tanks. Material Flow Analysis (MFA) was then performed for the production of 1 cubic meter of concrete, wherein both cement production and transportation were identified as sites of increased greenhouse gas emissions. As such, potential material alternatives must be considered, in addition to the comparison of as-built plans with the standard.
