The main concern of this research is to estimate energy performances of different
scenarios of the hypothetical model of the office building in downtown of Belgrade.
Specific conditions of sites in downtown make limitations in building design and
application of energy efficient systems, but also represent a provocation for architects.
Methodological approach entails three steps: design of different models of the office
building, numerical simulations of the models in PHPP’2007 software and
comparison of the results. For each hypothetical model of the office building three
scenarios are created: basic scenario and scenarios of different solutions of envelope
design regarding shading devices types. The design of hypothetical models and
various scenarios is carried out through the educational process on the Master studio
design project. Results are considered and presented through the heat and cooling
energy demands as well as reduction of energy consumption for cooling in summer
period by implementation of different shading devices. CO2 emissions are also
discussed. Design methodology as well as results could generally be applicable for
new office building design, both in Belgrade and in similar climatic conditions
