Using ESCO model to improve energy efficiency, water use efficiency and implement renewable energy sources in Hospital Centre Split - location Križine.
Hospital Križine had significant energy consumption and main objective of this project is to implement and promote measures related to production of renewable energy and measures aiming for improvement in energy efficiency and energy management in public sector, using ESCO model for co-financing projects. Buildings (includes residential housing, office and public buildings) are the largest energy consumers in Croatia, with around 43% of total energy consumption.
Therefore, one of the goals is to secure that public buildings contributes to the achievement of the RES and EE targets in order to comply with the EU 2020 objectives. That will also reduce their expenses and improve the quality for the users.
The main problem in Clinical Hospital Centre Split was the energy inefficient building and relatively high heating/cooling costs that made daily life in the building less comfortable for the patients. Public procurement for ESCO company was published by National Agency for Public Real Estate Management.
The goals of the project are reached through thermal insulation of the building envelope including roof, replacement of doors and windows and also by installation of solar panel and heating pumps. Heating system was improved by deep reconstruction with automatic regulation. New energy efficient lighting system was installed and also deep renovation of water supply system was conducted.
Resources needed
Total value of the project was 10,4 million €. Environmental Protection and Energy Efficiency Fund contributed with 3,6 million € (35%) and ESCO company (Rudan Ltd.) made private investment of 6,8 million € (65%). The return on private investment is achieved from energy savings by ESCO contract.
Evidence of success
Annual savings are 56% in energy consumption and 72% in water consumption. Heating system improvements (deep reconstruction of heating system with automatic regulation);
The project contributes to decrease of CO2 emissions and improving the standard for patients.
Olso contributed to raising awareness of the benefits of use RES in hospitals.
Difficulties encountered
No notable difficulties encountered.
Potential for learning or transfer
The ESCO model is quite new in Croatia but achieve significant saving in energy consumption, costs and CO2 emissions. This model of financing covers the development, performance and financing of projects with the aim of improving energy efficiency and reducing costs for operation and maintenance. Energy Service Company (ESCO) is obligated to gather and prepare all relevant technical documentation and make deep renovation in hospitals. Savings achieved through energy renovation and RES are used for paying the service charge to ESCO, who is responsible for maintenance of the buildings and the equipment during contracting period of energy service between ESCO and the public building.
National Agency for Public Real Estate Management continues to implement this program for public buildings in Croatia.
