Cost-related analysis of implementing energy-efficient retrofit measures in the residential building sector of a middle-income country – A case study of Bosnia and Herzegovina

This study presents an in-depth analysis of the cost structure when planning EE retrofit measures in residential sector Bosnia and Herzegovina. The showed that implementing would result substantial energy savings single-family houses, however, specific per resident for houses is on average 2.8 times higher than other three categories; multi-family apartment buildings, high-rise buildings. When considering ratio between investment costs GDP capita citizens Herzegovina have four lower ability to finance compared representatives EU members therefore government subsidy schemes may be inevitable successfully strategies. general conclusion based cost-effective investments, not financially viable buildings even if supported by subsidies due very low prices sources (coal wood) used these building prototypes. On contrary, are mainly driven natural gas light distillate fuel oil, show a great retrofit-driven profitability in. Looking at financial assessment outcomes, most significant benefits related scenario accounts improvement external wall insulation, window glazing, improving heating station efficiency. carbon emission reducing relative averaged CO2 strongly replacing existing partly coal-burned furnaces (80% firewood + 20 % coal) with exclusive fueled systems. measure enormous impact from (minimum 83.1 %), which cover 93.1 total stock benefit middle-income governments their aim translate potential nationwide economic energy-saving policy.
