Indoor Environmental Quality Design of Healthcare Buildings under LEED v4 BD+C: Healthcare, Case Study: MedPark Hospital

Abstract

This study examines architectural design strategies that enhance Indoor Environmental Quality (IEQ) under the LEED v4 BD+C: Healthcare framework, which places greater emphasis on occupant health outcomes compared to previous LEED versions. MedPark Hospital is employed as a case study. The research adopts a qualitative approach through literature review and project document analysis to explore the integration of architectural design, building systems, and IEQ credits. The findings reveal that integrated strategies addressing indoor air quality control, low-emitting material selection, thermal comfort, interior lighting, and acoustic performance significantly contribute to reducing health risks, improving staff performance, and supporting patient recovery. The study demonstrates that LEED v4 BD+C: Healthcare can function as a systematic design framework for healthcare buildings responding to urban environmental challenges and sustainable development goals.
