Abstract. This article discusses the consequences of intensifying
the wintry heat insulation demands on the constructional design of the
heat transfer surface. The discussion is based on the expected development
of the German thermal insulation regulations (GTIR). The new GTIR leads,
compared with today's standards, to a superproportional increase in the
thickness of the thermal insulation layers of external building components.
The effect of this new developments on the energetic boundary states and
on the sound protection will also be discussed. Special attention will
be given to the choice of environmentally fair building materials. This
will be done in accordance to primary energy content, the capability of
recycling, permanency, toxicity in the case of fire etc. The advantage
of timber building constructions (e.g. demolition of timber buildings requiring
low energy consumption, wood as a regenerative building material with a
closed CO2-circuit) will be additionally presented.
IZGRADNJA STANOVA U 21. VEKU
U radu je dat prilog projektovanju termoizolacija u uslovima njihovih povećanih
zahteva u uslovima zimske temperature i posledicama kada ima takvo projektovanje
površinskih slojeva za prenos toplote. Razmatranje se zasniva na očekivanom
inoviranju nemačkih standarda za toplotnu izolaciju (GTIR). Novi standardi
GTIR, u poređenju sa današnjim standardima, vode ka ekstraproporcionalnom
povećanju debljine slojeva za termičku zaštitu koju predstavljaju spoljne
komponente na objektu. Efekti inoviranja standarda za energetska granična
stanja i na zaštitu od zvuka su takođe razmatrani. Posebna pažnja biće
posvećena izboru prikladnih građevinskih materijala u odnosu na lokaciju
objekta i u saglasnosti sa primarnim energetskim sadržajem, trajnošću,
kao i posledicama od požara. Prednost objekata izgrađenih od drveta biće
prezentirana u sledećim radovima.
