Obnova toplotnega stavbnega ovoja večstanovanjske stavbe z vrednotenjem ekonomske upravičenosti

Stamač, Jure (author), Kunič, Roman (mentor)

V diplomski nalogi je teoretično izvedena energetska sanacija večstanovanjske stavbe v Ljubljani. Stavba je bila zgrajena leta 1963 in po stavbnem ovoju ni dodatno nameščene toplotne izolacije. Ker se je investitor odločil za prenovo fasade, se je pojavilo vprašanje, če je namestitev toplotne izolacije po objektu potrebna oziroma sploh smiselna, čeprav je v skladu z veljavno zakonodajo ob obnovi stavbe nujna. V diplomski nalogi je na podlagi pravilnika o učinkoviti rabi energije v stavbah in obravnavi treh vrst toplotne sanacije ter njihovih variacij v programu KI Energija 2014 dokazana nujnost namestitve toplotne izolacije in ekonomska upravičenost posameznega posega. Na podlagi izračuna neto sedanje vrednosti pa je določena povračilna doba investicije. Izvedene so simulacijske analize za primere namestitve 50 % in tudi 100 % povečane debeline toplotne izolacije glede na minimalne zahteve po veljavnih predpisih in posledični vpliv na ekonomsko upravičenost.

• Title: The renovation of the residential building's thermal envelope including evaluation of economic viability

Abstract

The aim of this thesis is theoretical energy renovation of residential building in Ljubljana. The building was built in 1963 without additionally installed thermal insulation on buildings thermal envelope. Since the investor decided to renovate the buildings envelope, the question arised, if the installation of thermal insulation is required, or even sensible, eventhough it is, based on current legislation. The thesis is based on the regulation on energy efficiency in buildings and consideration of the three types of thermal renovation and their variations in the program KI Energija 2014. It proves the necessity of the installation of thermal insulation and the viability of individual prejudice. The payback period of the investment is based and determined on calculation of the net present value. Simulation analyses are made for three thicknesses of thermal insulation – determined by current regulations and its 50 % and 100 % increased thickness.
