Magistritöö Maaehituse õppekaval Suur energia tarbimine on saamas üheks suurimaks probleemiks maailmas. Ehitussektoris saab vähendada energia tarbimist kui ehitada ja renoveerida hooneid, mis tarbivad vähem energiat. Käesoleva magistritöö eesmärgiks on uurida, kas 1988. aastal ehitatud eluhoonet on võimalik renoveerida liginullenergiahooneks. Eestis peab oluliselt rekonstrueeritav hoone vastama energiamärgise C-klassile, kuid renoveeritud liginullenergiahoone peab olema sama energiatõhus kui uus hoone. Hoone kohta viidi läbi energiasimulatsioonid kasutades simulatsioonitarkavara EnergyPlus ja OpenStudio. Renoveerimislahendused leiti kolmes erinevas järgus. Esmalt leiti lahendus, mis vastas oluliselt rekonstrueeritavale hoonele, seejärel lahendus, et hoone vastaks madalenergiahoonele ja lõpuks liginullenergiahoonele. Energiasimulatsioonidest saadud tulemuste põhjal on liginullenergiahoone renoveerimislahenduse energiatõhusarvuks 144 kWh/(m²·a) ja hoone vastab liginullenergiahoone energiatõhususele. Energy consumption as a whole is becoming a bigger problem in the world. In the construction sector the energy consumption could be reduced by building and renovating buildings which consume less energy. The aim of this Master`s thesis is to find out whether it is possible to renovate a singlefamily house built in 1988 to nearly-zero energy building (nZEB). In Estonia there are energy performance requirements for deep renovation. Then the building has to meet the energy requirements for C-energy label. A renovated nZEB must have same energy performance level as a new building.The energy performance is simulated using EnergyPlus and OpenStudio programs. There were three different types of renovation solutions found, first equal to deep renovation and then to low-energy building and finally to a nearly-zero energy building. According to the data gathered from energy simulations the renovation solution chosen for nZEB has energy usage of 144 kWh/(m²·y) and the building meets the energy performance requirements for nZEB. |
