[Gel/kW*h] where T- is the tariff of gas [Gel/m 3 ] . P=1.25/8.26=0.15 Gel/kW*h6.2 Calculated and Baseline Energy ConsumptionThe baseline energy consumption of the Municipal Hospital Building in Bakuriani necessaryto ensure normal operating conditions was determined as approximately 288540 kWh/yearfor space heating, 3871 kWh/year for hot water supply with local boiler, and 14476 kWh/yearelectricity for lighting system purposes.The building is characterized as one with a medium thermal capacity.The decision to undertake an energy audit was made because a building renovation iscurrently being carried out, thus the aim of this energy audit is to estimate the energyconsumption and ENCON potential in the building and to develop further recommendations.Energy BudgetThe calculated and measured energy consumption before and after the implementation ofthe energy efficiency and renovation measures are summarized in the following EnergyBudget Table.Budget ItemENERGY BUDGET - ENERGY AUDITBefore EECalculatedBefore EEMeasuredBefore EEBaselineAfter EE andRenovation[kWh/m²year] [kWh/m²year] [kWh/m²year] [kWh/m²year]Heating (1 st floor) 354.7 354.7 436.5 348.9Ventilation 46.0 46.0 46.0 46.0DHW 5.9 5.9 5.9 5.9Fans/ Pumps 10.5 10.5 10.5 10.5Lighting 21.9 21.9 21.9 7.3Various 14.9 14.9 14.9 14.9Cooling 0 0 0 0Total 453.8 453.8 535.8 433.5Budget ItemENERGY BUDGET - ENERGY AUDITBefore EECalculatedBefore EEMeasuredBefore EEBaselineAfter EE andRenovation[kWh/year] [kWh/year] [kWh/year] [kWh/year]Heating (1 st floor) 234435 234435 288540 230619Ventilation 30433 30433 30433 30433DHW 3871 3871 3871 3871Fans/Pumps 6960 6960 6960 6960Lighting 14476 14476 14476 4825Various 9857 9857 9857 9857Cooling 0 0 0 0Total 300031 300031 354137 286565Figure 1.
