Design scenarios for an office building – energy and environmental aspects

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
