The Bright Green Hospitals Case Studies of Hospitals' Energy Efficiency And Flexibility in Philippines

Hospitals usually operate 24/7 and consume a large amount of electricity to provide service and deploy critical machines that require reliable electricity. To maintain the energy reliability, hospitals usually equip diesel electricity generators, which are expensive and produce greenhouse gas (GHG) emissions. Therefore, there are potentials for hospitals to improve energy efficiency and provide energy flexibility to the electricity grid. However, due to specific functions of hospital buildings, the general concept of bright green buildings does not fit hospital buildings. Therefore, this paper aims to define and discussion the concept of bright green hospitals. A case study of two hospitals in the Philippines is selected to investigate energy management practices and installed intelligent technologies in hospitals. The “bright green hospitals” improve occupants' comfort, reduce energy consumption and carbon emissions, and keep energy reliability with intelligent technologies. Meanwhile, stakeholders' involvement takes an important role in the bright green buildings. This paper also finds that political, economic, social and technological factors affect the energy management in hospitals.
