Retrofitting for Improving Indoor Air Quality and Energy Efficiency in the Hospital Building

Abstract

A growing body of research shows that retrofitting practices can potentially reduce energy demand in hospital buildings and enhance indoor air quality. Yet, there is a lack of comprehensive reviews associated with green retrofitting practices in hospital buildings. This study aimed to undertake a systematic review of the past literature on retrofitting techniques used to improve indoor air quality and energy efficiency in hospital buildings, to identify barriers to its uptake, and to recommend solutions to identified challenges. For this reason, a systematic review was conducted for the published research from various academic databases. Findings showed a growing uptake of various retrofitting strategies for indoor air quality in hospital buildings. As a result, hospital management or building owners might consider addressing these challenges to facilitate the uptake and implementation of retrofitting practices in their facilities.

Going green in Singapore: insights and challenges in working towards achieving net zero in anaesthesia

“…This is more pronounced in ORs due to the single-pass high ACH required to maintain air quality and prevent particle accumulation and infection during surgery. [ 25 ] The ACH may be reduced during nonoperating hours, with guidelines recommending a minimum of six ACH to maintain positive pressure and indoor air quality. [ 26 27 ] An infection control study showed that turning off OR ventilation at night and restarting it 30 min before surgical activity did not affect the particle or microbial count.…”

Implementasi Ekoefisiensi Rumah Sakit Ramah Lingkungan (Green Hospital) di Rumah Sakit Daerah Nganjuk

“…Rumah sakit beroperasi 24 jam sehari 7 hari seminggu, dan selama beroperasi fasilitas kesehatan ini harus mempunyai persyaratan untuk pengelolaan limbah, penataan cahaya ruangan, pengaturan udara bersih dan pengendalian penyakit. Jadi, bangunan fasilitas kesehatan menggunakan sejumlah energi dengan proporsi yang tidak sama dibandingkan dengan bangunan yang berukuran sama seperti gedung komersial atau gedung untuk tempat tinggal (Radha, H., 2023). Berkaitan dengan hal tersebut diperlukan upaya untuk melakukan eko-efisiensi dengan mengimplementasikan rumah sakit ramah lingkungan (green hospital).…”
