Integrated strategy for healthcare facilities towards energy consumption reduction, proper energy system usage and regulation via BMS, integration of renewables
Versilia Hospital is an example of integrated strategy for healthcare facilities towards:
• Reduction, in terms of energy consumption, with attention to all aspects of the building from an architectural and structural point of view (e.g. a co-generator turbine that produces 600 kW electrical, 630 kg/h of steam at 8 bar and 400 kW of hot water at 90°C combined with the eco-efficient technologies already present in the facility: a CHP thousand-kw electric and photovoltaic panels that allows to produce 70% of electricity);
• Regulation, understood as proper energy system usage and regulation through automated systems (i.e. a BMS);
• Renewables, in terms of integration of energy production systems from renewable (a PV Plant of 195 kWe / 1.240 m2 and a Micro Wind Power plant for the production of electrical energy with a unique wind turbine of 3.30 m x 2.20 m for a power of about 6 kWe).
Built in 2002 with all the newest technology standards and equipped with energy efficiency measures, the facility underwent some renovation work in 2010, aimed at finding solutions and strategies to overcome barriers to wider application of measures for energy efficiency and use of renewable energy systems in healthcare facilities.
The hospital has been designed to make the most rational use of energy, according to the principle of eco-efficiency to combat waste and to minimize the emission of harmful substances into the atmosphere.
Costs for planning amount to 1,6M€ with a tot. investment of ca 100M€ on energy efficiency construction and renovation works. Direct costs for the energy team (energy management & monitoring) and materials are around 60.000€/y. Indirect costs for regulations and performance checks are of 50.000€/y.
Evidence of success
The strategy has allowed to constantly lower the facility energy consumption since 2002, reaching a -30% in 8 years.
The hospital is now class B.
CO2 savings are calculated to 210 TEP and 600 tons per year.
The initial achievements reached in a complex structure such as a healthcare facility encourage the prosecution of this winning strategy, producing long-term benefits in the management and willing to continue the implementation of more green solutions.
The difficulties encountered are mainly related to the analysis of the building and the search for all data at a level of accuracy suitable for the purpose.
The lesson learned is that programming of substantial interventions leads to excellent results.
Potential for learning or transfer
This good practice has high level of transferability of planning. Health facilities, because of their energy-consuming nature, allow an extraordinary opportunity in the field of rationalization of consumption and therefore of the public current expenditure, and represent excellent sites for the development of new technological solutions, thanks to the high visibility of the results. The implementation of the same good practice can be easy, so the transferability is really high. Insulation, renewable energy, promotion of technological innovation, monitoring the provision of energy services, control of lighting, heating and air-conditioning activities are applicable to all public buildings. The selection process is a good monitoring system (market research, system comparison, etc.) and is transferable. All these aspects can be translated into training and educational materials, which can increase the transferability of capacity buildings.
