2 CONTENT  introduction  energy efficiency policy  energy efficiency market  energy audits

3 INTRODUCTION HISTORY OF ENERGY EFFICIENCY  STRATEGY OF ENERGY SECTOR DEVELOPMENT IN CROATIA in 1998 and 2002  NATIONAL ENERGY PROGRAMS in 1998 coordinated by EIHP  PLINCRO gasification in Croatia  TRANCRO energy efficiency in transport  KOGEN cogeneration  MIEE network of energy efficiency in industry  MAHE small hydroelectric power plants development  SUNEN energy from sun  BIOEN biomass and waste energy  ENWIND wind energy  GEOEN geothermal energy  KUEN building energy efficiency in buildings  KUEN cts energy efficiency of centralized heat production systems  CROTOK energy development on Croatian islands  ENERGY LAW energy efficiency and renewable energy sources

4 ENERGY EFFICIENCY POLICY TECHNICAL REGULATION CONCERNING HEAT ENERGY SAVINGS AND THERMAL PROTECTION IN BUILDINGS OG 79/2005 Partly harmonised with Directive on Energy Performance of Buildings 2002/91/EC  technical demands on heat energy savings and thermal protection to achieve in design of new buildings and refurbishment and reconstruction of existing ones which are heated on space temperature higher than 12°C  yearly required heat energy consumption in buildings is limited  in Master Project - calculation of thermal performance of building - statement of required heat energy for heating  building maintaining regarding heat energy savings and thermal protection  technical demands for building products  other technical demands on heat energy savings and thermal protection

5 ENERGY EFFICIENCY POLICY TECHNICAL REGULATION CONCERNING HEAT ENERGY SAVINGS AND THERMAL PROTECTION OG 79/2005 CONTINUED Elemental U-values of Building Regulations (heat transfer coefficient) U ≤ 1,80 W/m 2 K for windows Yearly required heating per unit of usable building surface area Qh'' (kW  h/m 2  a) (residential buildings) f 0 ≤0,20Q h =51,31 kWh/m 2 0,20≤ f 0 ≤1,05Q h =41,03+51,41f 0 kWh/m 2 f0≥1,05Q h =95,01 kWh/m 2 Yearly required heating per unit of building section volume Qh' (kW  h/m 3  a)(non-residential buildings) f 0 ≤0,20Q h =16,42 kWh/m 3 0,20≤ f 0 ≤1,05Q h =13,13+16,45f 0 kWh/m 3 f 0 ≥1,05Q h =30,40 kWh/m 3

6 ENERGY EFFICIENCY POLICY NEW PHYSICALL PLANING AND CONSTRUCTION LAW 10/07 Partly harmonised with Directive on Energy Performance of Buildings 2002/91/EC 6 important building characteristics  heat savings and thermal protection must be achieved regarding local climate conditions  energy consumption for heating, cooling and ventilation should be equal or lower than prescribed values  satisfactory indoor climate conditions must be provided energy characteristics of buildings  every building must be designed, built and maintained during its usage in order to provide prescribed energy characteristics  before Use permit/ownership change/lease certificate of building’s energy characteristics by authorised person must be provided and presented  for public buildings obligatory open certificate presentation  building’s energy characteristics calculation procedure, certification procedure, authorisation of energy certification experts will be regulated by later technical regulation

7 ENERGY EFFICIENCY POLICY FULL IMPLEMENTATION OF DIRECTIVE ON ENERGY PERFORMANCE OF BUILDINGS Working group formed by Ministry of Environmental Protection, Physicall Planning and Construction in January 2007  necessary L aw and R egulation changes  quality action plan with defined goals: till end of 2008 transposition in national legislation, till end of 2011 obligatory energy certification of buildings  standards for energy certification  defining energy consumption limits and categories  education of energy experts trained for energy audits of buildings  documented procedures and tools (software) and further general preparation of information campaign

8 ENERGY EFFICIENCY POLICY MASTER PLAN FOR ENERGY EFFICIENCY Harmonisation with the Directive 2006/32/EC on energy end-use efficiency and energy services Working group formed by Ministry of Economy, Labour and Entrepreneurship in May 2007  appreciation of national goal  energy policy and legislation change  tax policy and public procurement procedures  institutional capacity  cross-sector issues  benchmarking  public and private sector scenarios and priorities

9 ENERGY EFFICIENCY POLICY RES AND COGENERATION Based on Energy Law:  Tariff system for renewable energy sources and cogeneration  Decree on minimum share of electricity from renewable energy sources and cogeneration  Decree on fees for promotion of electricity from renewable energy sources and cogeneration Based on Law on electricity market:  Regulation on use of RES and cogeneration  Regulation on eligible producer of electricity

10 ENERGY EFFICIENCY MARKET Energy efficiency market potential in Croatia is up to 320 million € Source: HEP ESCO, web site,2007 Source: EIHP

11 ENERGY EFFICIENCY MARKET Source: EIHP

12 ENERGY EFFICIENCY MARKET DRIVERS GRANTS INTERNATIONAL  WORLD BANK  UNDP  GEF  EUROPEAN COMMISION  OECD  IEA  EBRD NATIONAL  CROATIAN BANK FOR RECONSTRUCTION AND DEVELOPMENT  FUND FOR ENVIRONMENTAL PROTECTION AND ENERGY EFFICIENCY  HEP ESCO

13 ENERGY EFFICIENCY MARKET DRIVERS CONTINUED FUND FOR ENVIRONMENTAL PROTECTION AND ENERGY EFFICIENCY  established in 2003 by the Government of Republic of Croatia  collecting assets for financing projects, programmes and activities in sustainable use, improvement and protection of environment, financing national energy programmes and other projects for improving energy efficiency and use of renewable energy sources  activities in energy efficiency in 2005: financing energy audits in commercial sector and industry  activities in energy efficiency in 2007: financing energy audits in public and private business sector  future activities: financial stimulation for energy efficiency improvement and use of renewable energy sources in households

14 ENERGY EFFICIENCY MARKET FUTURE NEEDS MARKET DEVELOPMENT THROUGH STIMULATIONS  energy audit financing mechanisms  production and trade of energy efficient materials and equipment  energy efficiency improvement in households  promotion of energy production from renewable sources

15 ENERGY AUDIT NEP – EE SURVEY  general data about the building its type, purpose, year of the construction, year of the reconstruction, climate data, ownership  constructions characteristic total surface and heated area, window frame type and glazing, external wall, roof and floor type  energy indicators energy consumption for heating and cooling on a monthly basis, electricity consumption, characteristics of the heating, hot water and cooling systems, ventilation system and all other energy demand, including passive heat gains  living comfort annotations from the owners or management of the building  final conclusion and suggestion measures in at least two categories  smaller investment expenses and fast implementation  more expensive investment with obligation to conduct detailed energy audit and feasibility study

16 ENERGY AUDIT CLASSIFICATION ACCORDING TO LEGISLATION ENERGY EFFICIENCY METHOD = ENERGY AUDIT ENERGY CERTIFICATION GRADING ACCORDING TO ENERGY CONSUMPTION IN BUILDINGS

17 ENERGY AUDIT NEP PILOT PROJECTS 235 kWh/m 2 ► 81 kWh/m kWh/m 2 ► 70 kWh/m kWh/m 2 ►72 kWh/m 2
