Solar energy as a tool of renovating soviet-type multi apartment buildings

Abstract

The paper analyses the energy and technical possibilities of installing systems that use renewable energy sources (solar energy) to renovate soviet type apartment buildings. The aim of the analysis is to study the possibilities of using solar energy systems to renovate apartment buildings (five-storey, nine-storey and sixteen-storey), which are built in Lithuania, provide detailed conclusions about the energy and engineering aspects of such systems. The authors also intend to determine the optimal technological combinations and solutions that would allow achieving maximum energy benefits (solar collectors for domestic hot water preparation and photovoltaic panels for electricity use). For the research computer simulation tools EnergyPRO and PV*SOL Premium were selected. Actual collected heat and electricity consumption data is also used for the analysis.
