Analiza energetskih prihrankov v domovih za starejše občane : diplomska naloga

Kunič, Marko (avtor), Košir, Mitja (mentor), Pajek, Luka (komentor)

V nalogi so analizirani energetski prihranki v petih domovih za starejše občane v Sloveniji, ki so bili sanirani v letih 2012 in 2013. Ti so bili na razpisu za celovito energetsko obnovo izbrani na podlagi točkovanja ukrepov iz razširjenega energetskega pregleda, ki jih je za Ministrstvo za delo, družino in socialne zadeve v letu 2009 pripravilo podjetjeGGenera- Proplus. Za analizo izbrani domovi imajo enostavnejšo arhitekturno zasnovo in so bili pripravljeni posredovati podatke o porabi energije za študijske namene. Naloga omogoča podrobnejši vpogled v postopek izdelave in vsebinski obseg razširjenega energetskega pregleda, s poudarkom na uporabljenih metodah za izračun gradbene fizike in avtorski analizi porabe pred sanacijo in po njej. Prihranki za analizo so bili delno povzeti iz EP (s poenostavljeno IJS metodo izračunan učinek ukrepov), kot tudi poustvarjeni s programskim orodjem NovoCAD, ki sicer velja danes zaradi ohlapnejših kriterijev in metode izračuna za zastarelo. Merilo uspešnosti je seveda čim boljše ujemanje izračunanih prihrankov z dejanskimi. V ta namen sem naredil dva dodatna kontrolna izračuna gradbene fizike z bolj aktualnim programom KI Energija in rezultate primerjal z merjenimi prihranki in s primerjalnim izračunom dokazal, da je z vidika natančnosti izračunov boljša izbira. V zaključku analize je izračunana stopnja uspešnosti napovedanih prihrankov z metodo HI-kvadrat in T-testom. Ujemanje vseh štirih načinov izračuna se je statistično pokazalo zadovoljivo (celo do 91,4 %); kontrolni izračuni žal niso izkazovali ujemanja kontrolnih izračunov z dejanskimi prihranki. Navkljub skladnim kontrolnim rezultatom, izračunanih s programom KI Energija, ti zaradi premajhnega vzorca statistično niso izkazovali ujemanja.

Izvleček

In this thesis, we analysed energy savings in five retirement homes in Slovenia which were renovated in 2012 and 2013. These took part in public tender for a complete energy renovation and were selected on the basis of point-system for measures from an extended residential energy consumption survey (RECS). The basis for comparison are the calculations for the estimated consumption in RECS, which were prepared through joint venture withgGenera-Proplussby the Ministry for labour, family and social affairs in 2009. Retirement homes chosen for the analysis have a simpler architectual plan and were willing to share the data on consumption of energy for study purposes. The thesis enables more detailed insight in the procedure composition and the content scope of extended RECS, with emphasis on the used methods for calculating building physics and authorial analysis brefore and after renovation. Savings for analysis were calculated wit a simplified method as well as with NovoCAD program tool, which is today considered outdated because of loose criteria and methods of calculation. The mesaure of success is valid agreement of calculated savings with actual savings. For this purpose, we made a control calculation of building physics with a newer program KI Energija and the results were compared with measured savings. With reproduced calculations we proved that the program is a better choice from viewpoint of accuracy. In the end of the analysis we calculated the level of success of the estimation of savings with Chi-squared test and T-test. All used methods proved to be statistically in agreement (even up to 91,4 %); the actual control calculations unfotunately did not show agreement of calculations with actual savings. We reached better agreement of calculated savings in control calculations with program KI Energija – statistically this one did not show agreement because the sample was too small.
