02.13 |
Specific comfort criteria for new buildings, provide specific parameters for instance for airtightness, minimum ventilation rates |
yes |
The air change rate of indoor air in buildings where persons stay or work shall be at least 0.5 h‐1. At the time when the building is unoccupied, an air change rate of at least 0.2 h‐1 should be provided. The lowest air change rate shall be higher in individual parts of the building if necessary for the purpose of avoiding threats to hygiene and health conditions, and/or due to the use of open‐flame heating and/or cooking devices. If it is not possible to ensure natural air ventilation that meets the requirements for the prescribed air quality, hybrid or mechanical ventilation should be designed. For multi‐family residential buildings, airtightness requirements must be fulfilled for each apartment. For non-residential buildings, airtightness requirements must be fulfilled for the building envelope. Air permeability classification of windows, balcony doors and skylights shall comply with the requirements specified according to HRN EN 12207:2011. Indoor air comfort shall be determined by fulfilling requirements for heating, cooling, ventilation, thermal stability, indoor surface temperature, humidity, proper lighting and allowed noise. Recommended design values are determined in HRN EN 15251:2008. |

Overall minimum requirements in case of major-renovation |
Major renovation of a building means the renovation of a building where more than 25% of the surface of the envelope undergoes renovation. In the case of major renovation, the heat transmission coefficient of the entire building element shall fulfil the prescribed requirements. Buildings undergoing major renovation shall fulfil at least 10% of energy demand from RES which can be obtained from district or block heating based entirely or partially on energy from RES unless it is technically, functionally and economically feasible. When reconstruction covers more than 75% of the surface of the heated building envelope, requirements are set on QH,nd, Eprim, Edel.

Additional training demands for assessors |
The successful completion of the appropriate professional training programme (Module 1 and Module 2) is mandatory. Programmes are carried out by authorised institutions. Module 1 enables authorisation for energy audits and certification of buildings with a simple technical system, and Module 2 enables authorisation for energy audits and certification of buildings with a complex technical system. Module 1 has a duration of 40 hours and contains themes related to regulations, themes from the field of building physics, on heating systems, electric lighting, on the methodology of carrying out energy audits and applying computer tools. Module 2 also has a duration of 40 hours. It builds on the themes of Module 1, but with additional themes, e.g., RES, alternative energy supply systems, cooling devices, regulation and automation systems in buildings, electric lighting in buildings, public lighting, etc. Authorised persons have the obligation to attend annual programmes of skill upgrading. In Croatia, there are 11 regionally distributed institutions (faculties and professional organisations) that were granted authorisation for carrying out the training programme. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||

Yes, the ‘Information system of energy certification (IEC)’ is an application for issuing, storing and controlling energy certificates, reports on energy inspections of buildings, as well as reports on regular inspections of heating and cooling or air conditioning systems in buildings. The IEC contains a database of energy certificates, reports on energy inspections of buildings, reports on regular inspections of heating systems and cooling or air conditioning, as well as persons authorised to perform building energy certifications and audits and persons authorised to control and implement training programmes. |
