Impact of the proportion of glazing surface in south facade on energy efficiency of prefabricated timber buildings

Vesna Žegarac Leskovar (Author), Miroslav Premrov (Author)

Abstract

The paper presents the reasonability of using an increased proportion of glazing surfaces in prefabricated timberframe structural systems with a special focus on the energy certification of the building. The research is based on a case study of a two-storey house with a prefabricated timber-frame as well as with cross-laminated structural system with a parametric analysis of an increased-proportion-of-the-glazing-surfaces impact on south side of thebuilding, taking the climate data for Ljubljana into consideration. The analysis was carried out on different exterior wall elements having different thermal properties, while the rest of the parameters, such as the ground plan of the model as well as the active systems, roof and floor slab assemblies remain constant. The graphical presentation includes a function curve showing the annual energy demand for heating and cooling depending on the proportion of the glazing area in relation to the total surface area of the south façade of the building.

Secondary title:	Vpliv deleža steklenih površin na južni fasadi na energijsko učinkovitost montažnih lesenih stavb
Secondary abstract:	Prispevek prikazuje smiselnost uporabe povečanega deleža steklenih površin v montažni leseni gradnji s posebnim poudarkom na energijskem izkazu stavbe. Pri tem so parametrično na modelu dvoetažne stanovanjske hiše analizirani vplivi povečanega deleža steklenih površin na južni strani objekta ob upoštevanju klimatskih pogojev za Ljubljano. Objekt je obravnavan v okvirnem in križno lepljenem montažnem sistemu. Analizirani so različni tipi zunanjih sten z različno toplotno izolativnostjo, ostali parametri, kot so tloris objekta, sestava strehe, temeljne plošče, aktivni sistemi, pa v izračunu ne varirajo. Podana je funkcijska odvisnost letnih toplotnih izgub za ogrevanje in ohlajevanje v odvisnosti od deleža steklenih površin na južni fasadi objekta.
