Abstract

U radu se istražuje potencijal gradnje zgrade nulte energije na primjeru obiteljske kuće. Iz postojećih nacrta zgrade i podloga za unos slojeva materijala, izradit će se BIM model korištenjem računalnog BIM programa. U cilju istaživanja zgrada nulte emisije, provest će se četiri različita proračuna: i) potrebna energija za grijanje i hlađenje do razine zgrade gotovo nulte energije, ii) proračun emisije CO2eq plinova tijekom cjelokupnog životnog vijeka zgrade, iii) utjecaj toplinskh mostova i iv) dugoročno higrotermalno ponašanje. Proračun potrebne energije za grijanje i hlađenje zgrade do razine zgrade gotovo nulte energije proveden je koristeći satnu metodu proračuna kako je definirano u Algoritmu za proračun potrebne energije za grijanje i hlađenje prostora prema HRN EN ISO 13790. Kao rezultat proračuna dobije se količina potrebne energije u kWh po m2 korisne površine zgrade. Proračun emisije CO2eq plinova bazira se na količinama ugrađenog građevinskog materijala u predmetnu zgradu. Kao rezultat proračuna dobije se količina u kgCO2eq emisije stakleničkih plinova po m2 bruto površine zgrade. Za proračun vrijednosti toplinskih mostova korištene su numeričke metode. Kao rezultat proračuna dobije se duljinski koeficijent prolaska topline Ψ. Proračun dugoročnog transporta mase proveden je korištenjem numeričkih modela. Kao rezultat proračuna dobije se ukupni sadržaj vlage i vrijednosti relativne vlažnosti. Diplomski rad rezultirat će definiranom energetskom bilnacom zgrade te utjecajem na okoliš tijekom cijelog njezinog životnog vijeka.

Abstract (english)

The paper researches the potential of constructing a zero-energy building using a family house as a case study. From the existing blueprints of the building and the input information for layers of materials, a BIM model will be created using a computerized BIM program. Four different calculations will be conducted to investigate zero-emission buildings: i) required energy for heating and cooling to nearly zero energy building level, ii) calculation of CO2eq gas emissions throughout the building's entire lifecycle, iii) impact of thermal bridges, and iv) longterm hygrothermal behavior. The calculation of required energy for heating and cooling is performed using the hourly calculation method as defined in the Algorithm for calculating the required energy for heating and cooling spaces according to HRN EN ISO 13790. The result provides the amount of required energy in kWh per square meter of the building's net area. The calculation of CO2eq gas emissions is based on the quantities of embedded building materials in the building, resulting in the amount of kgCO2eq greenhouse gas emissions per square meter of the building's gross area. Numerical methods are used for calculating thermal bridge values, resulting in the linear thermal heat transmittance Ψ. Long-term mass transport calculation is carried out using numerical models, resulting in values of total moisture content and relative humidity. The thesis will result in a defined energy balance for the building and its environmental impact throughout its entire lifecycle.
