l effective plant maintenance and the resources necessary to ensure the best cost to benefit ratio for the polyclinic. The public-private partnership includes the drafting and implementation of a type of mechanical plant plan and the related development and maintenance of the technological assets and services provided using computerised protocols on activities, which help guarantee uniform results and the best cost to benefit ratio for the polyclinic.

Figures for the primary energy introduced into the system before the redevelopment, expressed in TOE, were: natural gas 8.224 TOE per year; electricity 9779 TOE per year; total 18.023 TOE per year. The primary energy introduced into the system by the new power plants was: natural gas 12.390 TOE per year (+50.7 per cent); electricity 912 TOE per year, of which 142 TOE per year transferred to the public network; total 13.160 TOE per year. The primary energy savings totalled 4.863 TOE
cent compared to previous figures). Regarding the updated configuration of the polyclinic and the new cardio-thoraco- vascular department, primary energy savings increased to 5090 TOE per year, with an overall reduction in climate changing emissions equivalent to 15.382 tons of CO2
each year.
Future prospects With the energy redevelopment implemented through project financing, the process of creating a sustainable hospital has begun. The redevelopment of the primary energy production and distribution system is an important step in interpreting in a new way the different and ever changing needs of an environment that exists to improve health. With power and efficiency implemented in the new plants, the polyclinic will be able to develop a technological renewal plan to address the expansion and increased efficiency of existing pavilions. This plan will enable the rational use of energy, which is ever increasing.
