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
 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 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

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

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 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
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


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
