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

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 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

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 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

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 onenergy 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

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

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
