Energy retrofitting of Hospital Firule, KBC Split

Location: Split, Dalmatia, Croatia

Population: 180,000

Climate: Continental climate, the summers are short, hot, and mostly clear, and the winters are long, cold, wet, windy, and partly cloudy

Duration: November 2016 – July 2017

Sector: Buildings

Funding sources: Public-private

City Networks:

Savings: 56% savings in annual electricity consumption, and 54% reduction in annual water consumption.

Multiple benefits: Better thermal comfort and indoor lighting for patients and medical works at the hospital.

Objective – To implement energy efficiency and reduce the energy consumption of the hospital.

Solutions – The Clinical Hospital Centre (KBC SPLIT-FIRULE) is the largest hospital centre in Dalmatia that employs approximately 3200 people. It is the central health institution of the Split-Dalmatia county and the entire southern part of Croatia and is located in three locations in Split: Firule, Križine and the centre of the City. About 1 000 000 citizens of the Republic of Croatia and about 500 000 inhabitants of the southern part of neighbouring Bosnia and Herzegovina, and 500 000 tourists gravitate to this regional hospital institution during the tourist season. The hospital owner is the Republic of Croatia, and the Government of Croatia performs the rights and duties of the founder.

Technical solutions of the energy retrofit:

• thermal insulation 24,000 m2 of the facade,
• thermal and waterproofing 13,500 m2 of roofs,
• replacing 9,000 m2 of outdated windows and doors with new PVC windows and doors
• replacement of 18,000 lighting fixtures,

• renewed climatization system,
• renewed boiler room and 11 thermal substations,
• new system of hot water preparation,
• fully renewed hospital laundry

The headquarters is in Split, Spinčićeva.

Funding – The project is funded through Energy Performance Contracting, and ESCO involved is Rudan [source].

Innovation – ESCO participation and the business model of Energy Performance Contracting [source].

Success factors – (1) High savings and financial viability of the project. Energy-generating product costs before renovation amounted to approximately 16.310.000,00 HRK per year, and after performed renovation, they amounted to approximately 7.800.000,00 HRK. The project itself will last 14 years, and the investment cost will be returned through savings. (2) Availability of competent ESCO and effective coordination so that the hospital’s continuous operation was not affected during the renovation. There were 150 to 180 workers every day on the site, in total 300 people from more than 30 Croatian companies worked on the project.

Significant outcomes:

Power consumption before energy renovation amounted to 34.227.000 kWh/year, and after renewal, it amounts to 19.000.000 kWh/year, which is a savings of 56%. In addition, water consumption was reduced by 54%, CO2 emissions by 62%, and 10% of total energy is produced from renewable energy sources.

Synergies with local policies:

• The Programme of energy renovation of public sector buildings 2014-2015, which covered this project;
• The Program promotes integrated renovation concept that includes renovation of buildings envelope, upgrades to the heating /cooling system water heating system, ventilation, lighting and water supply (source)

Political alignment:

• Aligned with EU policy of encouraging energy efficiency improvement in public buildings through energy performance contracting;
• An EU project covers the project

Marketability: replicable in regions with ESCO
