Due to the growing phenomenon of global warming, and increasing of air conditioning load in urban areas, it is a very important issue to reduce air conditioning energy consumption effectively and to improve the building energy consumption today. In this study (the fifth floor apartment in Taichung City), the simulated case we use energy simulation software Ecotect to the numerical simulation, such as the different modules of the roof garden, air conditioning situation and the timetable for the simulation project. Then take concrete roof as the comparison, we summed up the best combination of insulation and energy efficiency, and we extended the simulation results to the originalTaichung City for the energy efficiency assessment later.
In the generally moderate electricity situations (17-8) of urban housing in Taiwan, the result of research shows 1.The energy efficiency of eco-roof up to 19.5% in full air-conditioning mode. 2.The energy efficiency of eco-roof up to 13.9% in cooling only mode. 3. The energy efficiency of eco-roof up to 23.3% in mixed-mode. 4. If there are 70% of the housing roofs with eco-roofs that we can save maximum of 231,678,021 kWh per year, and consequential to save of NT 906,770,000 dollars. It also reduced the carbon dioxide equivalent emissions of 145,030 metric tons. We can found in this study that the efficiency to save the energy of eco-roof is high,setting the roof garden in the city can save energy effectively and reduce air conditioning load.
