| Outline of Final Research Achievements |
This research presented a simulation method of HVAC equipment load considered the combined effects of high-performance window systems and natural and energy-efficient mechanical ventilation systems. High- performance window systems are facades such as airflow windows, double skin facades and windows with high-performance glazing. Energy-efficient mechanical ventilation systems contain air-side economizers, demand control systems and heat recovery systems. Through thermal load simulations for about 840 cities in Japan, it was found that airflow windows are more effective for cold regions than for hot regions. Unlike airflow windows, double skin facades are more effective for hot regions. The similar energy-saving effects of natural ventilation and air-side economizer systems for buildings with high-performance windows can be expected in all cities in Japan, however the energy-saving effects of demand control and heat recovery systems are larger for cold regions than for hot regions.
