This paper aims to review the state of the art technologies for the energy efficiency within the hospitals sector. Hospitals are liable for an unstable amount of energy demand and joint emissions, because of their 24/7 nature of operation and hence resulting larger energy consumption than a typical commercial building. Additionally, they need high quality and warranted supplies of electricity. Due to increased energy demand and therefore the depletion of existing fossil fuel based sources, it is required to use the energy more efficient.

The Bali Province Technical Guidelines (written in Indonesian) for Implementing Green Buildings in the Context of Clean Energy represent a collaborative effort between the Bali Provincial Government, Global Building Performance Network (GBPN), and support from CORE Udayana. Developed through extensive studies and analysis from November 2021 to June 2022, the guidelines engage stakeholders from the Provincial Government Bali, Professional Expert Team, universities, associations, private sectors, and professionals in building and clean energy.

The Samarinda City Technical Guidelines represent a strategic initiative aligned with the city's development goals, as outlined in Mayor Regulation No. 55 of 2021.
