On the impact of urban micro climate on the energy consumption of buildings

The energy consumption of urban. buildings is affected by the surrounding microclimate which differs from standard weather data and by mutual obstructions between buildings, which decrease sunlight and wind potentials for internal solar gains and passive cooling. The building construction itself affects both outdoor and indoor microclimate. This research addresses these interdependences in respect with energy performance. An urban structures are investigated with a fixed value of H/W and solar orientation.. The numerical. method used is the building energy model (TRNSYS), for simulating building energetic and thermal responses to external and internal settings and the Sombrero software to evaluate the to evaluate the shading of surrounding buildings.
