Estimate of Energy Performance Indicator of Existing Single-Family Houses in Bosnia and Herzegovina

Abstract

Yielding from an overall quantitative study of the residential sector of Bosnia and Herzegovina (B&H), this chapter concentrates on the ratio between single-family and collective housing, as well as on the urban-rural ratio of the single-family housing. Based on the data from the existing building stock (buildings built by 2014) and the statistical estimates, 23% of the buildings belong to the urban areas and 77% belong to the rural areas. The main goal was to study the correlation between the characteristics of the building envelope, the shape factor (A/V ratio) and the energy savings potential for the application of conventional measures of refurbishment of the building envelope of the single-family houses (type of buildings, which dominate in rural and urban areas). The chapter wraps up with recommendations for the adequate level of the energy performance indicator (energy need for heating) for the approved energy class for single-family houses located in the climate zone of the northern B&H.

Energy Retrofitting Opportunities Using Renewable Materials—Comparative Analysis of the Current Frameworks in Bosnia-Herzegovina and Slovenia

“…Due to the better thermal characteristics of building envelope elements for buildings built in the period 1992-2014, the lowest relative savings are possible for single-family houses built in this period (32.43%) and for multifamily houses from the same period (33.77%) [32]. These measures do not correspond to the currently valid aforementioned Based on the data published in the typologies, the energy need for heating of all buildings in Republika Srpska is 8,427,652 megawatt-hours (MWh), of which 7,729,138 MWh belongs to residential buildings and 698,514 MWh to public buildings.…”

“…Due to the better thermal characteristics of building envelope elements for buildings built in the period 1992-2014, the lowest relative savings are possible for single-family houses built in this period (32.43%) and for multifamily houses from the same period (33.77%) [32]. These measures do not correspond to the currently valid aforementioned rulebook of the Republika Srpska, because the U-value for façade wall is more demanding (e.g., about 12 cm of thermal insulation on walls, thermal conductivity of 0.041 W/mK is required).…”
