description |
Buildings are one of the biggest energy consumers in urban environments, so
its efficient use represents a constant challenge. In public objects and
households, a large part of the energy is used for heating and cooling. The
orientation of the object, as well as the overall heat transfer coefficient
(U-value) of transparent and non-transparent parts of the envelope, can have
a significant impact on building energy needs. In this paper, analysis of the
influence of different orientations, U-values of envelope elements, and size
of windows on annual heating and cooling energy for an office building in
city of Nis, Serbia, is presented. Model of the building was made in the
Google SketchUp software, while the results of energy performance were
obtained using EnergyPlus and jEplus, taking into ac-count the parameters of
thermal comfort and climatic data for the area of city of Nis. Obtained
results showed that, for varied parameters, the maximum difference in annual
heating energy is 15129.4 kWh, i. e per m2 27.75 kWh/m2, while the maximum
difference in annual cooling energy is 14356.1 kWh, i. e per m2 26.33 kWh/m2.
Considering that differences in energy consumption are significant, analysis
of these parameters in the early stage of design process can affect on
increase of building energy efficiency. [Project of the Serbian Ministry of
