Abstract

Doktorska disertacija obravnava razvoj metodologije za ocenjevanje energijsko učinkovite prenove stavb z uporabo leseno-steklenih modulov nadgradnje. Z uporabo preprostih diagramov in enačb omogoča hitro oceno prihrankov potrebne energije za ogrevanje in hlajenje nadgrajenih (hibridnih) stavb na podlagi robnih pogojev (značilnosti leseno-steklenih modulov nadgradnje in obstoječih stavb) ob predpostavki, da so stavbe prenovljene na predlagani način. V skladu s tem je bila izvedena sistematična analiza različnih konstrukcijskih parametrov energetsko učinkovitih leseno-steklenih modulov nadgradnje (kot so etažnost, toplotna prehodnost konstrukcijskih elementov, velikost in orientacija zasteklitve, razmerje pokritosti strehe, itd.) in obstoječih stavb (etažnost, orientacija, tipologija stavb, itd.), za katere smo domnevali, da pomembno vplivajo na obseg vpliva ukrepa nadgradnje na energijsko učinkovitost celotne hibridne stavbe. Cilj te doktorske disertacije je tudi na novo opredeliti t.i. "optimalne" leseno-steklenih modulov nadgradnje, ki bi ustrezali različnim tipologijam, dimenzijam in orientacijam obstoječim stavb ter bi jih bilo tako mogoče uporabiti pri sodobnem arhitekturnem oblikovanju stavb, pri čemer bi poleg energijske učinkovitosti upoštevali tudi vizualno udobje. Raziskava je bila izvedena v štirih glavnih delih; prvi del obravnava analizo izbranih obstoječih stavb in njihovo prenovo. Drugi del obravnava zasnovo leseno-steklenih modulov nadgradnje, ki pa jo lahko razdelimo na dva dela. Prvi del sledi metodologiji, uporabljeni v doktorski nalogi Tine Špegelj (parametrična numerična študija), v drugem delu pa je bil razvit nov pristop, ki temelji na metodologiji optimizacije MINLP in je bil uporabljen za določitev optimalne zasnove leseno-steklenih modulov nadgradnje. V tretjem delu so razviti leseno-stekleni moduli nadgradnje uporabljeni na prenovljenih stavba, da bi analizirali njihov vpliv in posplošili rezultate, kar je v četrtem delu privedlo do razvoja metodologije za ocenjevanje energijsko učinkovite prenove stavb. Rezultati raziskave lahko služijo arhitektom, projektantom, gradbenim inženirjem in drugim strokovnjakom v zgodnjih fazah načrtovanja projektov prenove.

Secondary abstract:	This doctoral dissertation deals with the development of a methodology for estimation of energy efficient building renovation with the application of timber-glass upgrade modules. Through the use of simple diagrams and equations, it enables a quick estimation of savings in the energy need for heating and cooling of upgraded (hybrid) buildings based on boundary conditions (characteristics of timber-glass upgrade modules and existing building), assuming that the buildings are renovated in the proposed manner. Accordingly, a systematic analysis of various design parameters of energy efficient timber-glass upgrade modules (such as height, thermal transmittance of construction elements, size and orientation of glazing, rooftop coverage ratio, etc.) and of existing buildings (height expressed in number of storeys, orientation, building typology, etc.) was carried out, which we assumed to have a significant impact on the extent to which the extension measure affects the energy efficiency of an entire hybrid building. The goal of this doctoral dissertation is also to redefine the “optimal” timber-glass upgrade modules to correspond to different existing building typologies, dimensions, and orientations, and thus to be applied in contemporary architectural building design, taking into account not only energy efficiency, but also visual comfort. The research has been carried out in four main parts; the first part deals with the analysis of the existing case study buildings and their renovation. The second part deals with the design of timber-glass upgrade modules, which in turn can be divided into two parts. The first part follows the methodology used in Špegelj et al. (a parametric numerical study), and in the second part, a new approach based on the MINLP optimisation methodology was developed and used to determine the optimal design of timber-glass upgrade modules. In the third part, these are applied to renovated buildings to analyse their impact and generalise the results, leading to the development of a methodology for estimating energy efficient building renovation in the fourth part. The results of the research can serve architects, designers, civil engineers, and other professionals in the early design stages of renovation projects.
