This is the good practice's implementation level. It can be national, regional or local.
About this good practice
GREEN@Hospital project aims at integrating the latest ICT solutions in order to obtain a significant energy saving in existing hospital buildings and other public buildings, through a better management of energy resources and losses reduction.
Within the project a Web-based Energy Management and Control Systems – Web-EMCS– has been developed. It integrates, monitors and controls multiple buildings systems at the component level. Moreover models to assess the energy savings have been developed and algorithms for consumption optimisation implemented.
Four different hospitals have been selected across Europe to take part in the pilot in order to demonstrate the validity of the proposed solution under real operating conditions. Each hospital will make available specific areas selected considering the presence of: 1) renewable energy sources, 2) already available building management systems that can be easily integrated in the Web-EMCS, 3) refurbishing plans aiming at energy efficiency improvement
The work has been carried on in the three years of the project is structured to reach six main scientific objectives listed below:
• To develop a standard benchmarking model for energy measurement in hospital environment
• To develop and integrate a Web-EMCS
• To develop holistic control algorithms for energy consumption optimization
• To implement and validate the proposed solution (Pilots)
• To implement a maintenance service
• To disseminate the project results and educate

Expert opinion
ICT systems are increasingly important in efforts to improve energy performance. Such systems can keep an ever-present eye on energy use and be used to optimise performance, including automated control of technology. This pilot project is a good example of applying ICT in public buildings, tailored to the specific building requirements. It has had impressive results, with more than 50% energy savings and can be an inspiration for other regions looking to improve the performance of their public buildings.

Potential for learning or transfer
After the implementation phase, some problems related to the communication of the hospital’s infrastructure with the centralized Green@Hospital server had to solve. Another complication that was introduced and solved with the proper maintenance of the Green@Hospital equipment was a delay in the “switch on” of the artificial lights that has been identified due to slow communication speed of the existing BEMS with the Web-EMCS. Thanks to reporting of the clinic’s personnel and the maintenance team work, the problem was solved and the energy savings significantly increased during the latest months of the monitoring period. For the Green@Hospital solution set the Web-EMCS platform assists in the scheduling of maintenance plans for the installed equipment. The real-time monitoring provided by the Web-EMCS platform assists in identifying potential problems in the sensors (communication or validation) which can potentially affect the comfort level of users and the energy saving targets.
