INTRODUCTIONHISTORY 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
• KUENbuilding energy efficiency in buildings
• KUENcts energy efficiency of centralized heat
  production systems
• CROTOK energy development on Croatian islands
• ENERGY LAW 2004 - energy efficiency and renewable
  energy sources

ENERGY EFFICIENCY POLICYTECHNICAL 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 12C
• 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

ENERGY EFFICIENCY POLICYNEW 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 buildings energy characteristics
  by authorised person must be provided and
  presented
• for public buildings obligatory open certificate
  presentation
• buildings energy characteristics calculation
  procedure, certification procedure, authorisation
  of energy certification experts will be regulated
  by later technical regulation

ENERGY EFFICIENCY POLICYFULL IMPLEMENTATION OF
DIRECTIVE ON ENERGY PERFORMANCE OF BUILDINGS

• Working group formed by Ministry of Environmental
  Protection, Physicall Planning and Construction
  in January 2007
• necessary Law and Regulation 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

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

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

ENERGY EFFICIENCY MARKET

• Energy efficiency market potential in Croatia is
  up to 320 million

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 MARKETFUTURE 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 AUDITNEP 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
