Main Challenges in Chinese Hospitals Main Challenges in Chinese Hospitals
5
User behaviour (patients and staff)
Poor qualification of the technical staff bad maintenance
Overdesigned facilities high running costs
More than 54 % hospital buildings were built before 2005
no external wall insulation
High energy loss in the steam supply system (20-30%)
Old water pipe system
Problem with hydraulic balance in the heating and cooling system (controls and regulations)
Capacity shortage of hospitals
Project financing
Approaches and Technical Options for Energy Efficiency Measures Approaches and Technical Options for Energy Efficiency Measures
6
Approaches Awareness raising through energy benchmarking Energy analysis to uncover main problems Prioritize the energy efficiency measures using a catalog Start with simple measures with short pay-pack periods Set up pilot project for demonstration
Technical Options Quick steam generators Cogeneration/Trigeneration (KWK/K) Heat/Chill recovery technology External wall isolation Modernization of the heat/cooling
system Set up effective energy consumption
