65　Consideration of optimal design of natural exergy utilization system to realize ZEB

─Exergy evaluation of solar energy utilization systems─

Abstract

Simulation was conducted using a calculation model constructed based on actual measurements for a solar thermal utilization system that combines low-quality energy, heat, with high-quality energy, electricity, and fossil fuels.

The results suggested that improving the equipment's control logic and expanding the use of solar heat would be effective in reducing the environmental impact.
