Simulating the Carbon foot Print Reduction of an Arid Urban form Applying Canopy Layer Green Coverage under Climate Change Scenarios

摘要

As an overlap between micro and local climate scales, urban form design has recently attracted insights towards sustaining built environments, and would still in a mess without spot lighting to its measures in a time of changing climate. of those measures, carbon concentration is responsible for a major role in global warming. In this research, the domestic carbon foot print of an urban form in the arid climatic zone of Giza of Egypt has been estimated in present and future before and after applying urban canopy layer green coverage as an adaptive strategy for climate change. The suggested green coverage includes local trees in addition to green roofs and green walls. Both urban and building simulations were performed conjunctionally via a conversion cycle of EPW-CSV-EPW to relate canopy layer green coverage to indoor environment and its HVAC and domestic uses that conclude specific carbon emissions. This cycle is applied to let weather files represent outdoor interactions after applying the greenery elements that literally affect reductions might occur as only indoor simulations do not account for the cooling effects of greenery, for energy consumption and in turn for CO_2 reduction. Results show considerable reductions in CO_2 after adaptation but with variant values corresponding to the examined future climate scenarios (2020, 2050 and 2080).
