TRADITIONAL SERBIAN COUNTRY COTTAGE EQUIPPED WITH THE PASSIVE TROMBE WALL

Abstract

This paper investigates the passive use of solar energy in a traditional Serbian country cottage (<100 m2) in the vicinity of the city of Kragujevac – the implementation of the passive Trombe wall. Through a seven-month (from October 1 to April 30) comparison with a classic cottage (without the passive Trombe wall), the benefits of mentioned solar systems are determined. Both country cottages (created in the Google SketchUp program), and in the EnergyPlus program, are equipped with central heating systems with coal boilers (heat energy generators). The results showed that the consumption of useful (thermal) energy can be reduced from 4823.97 kWh to 3923.22 kWh, final energy from 7836.21 kWh to 6372.99 kWh, and primary energy from 10187.07 kWh to 8284.89 kWh. Environmental and economic indicators are also on the side of a country house with the passive Trombe wall: CO2 emission is reduced by 0.61 t, and financial investments for heating during the analyzed period are reduced from 312.49 € to 254.14 €.
