A multi-scenario life cycle impact comparison of operational energy supply techniques for an office building in Thailand

摘要: Abstract This study provides a life cycle assessment (LCA) of sustainably designed office building to be built in Thailand. The has gross floor area 6300 m2 and lifetime 50 years. An analysis four different energy supply scenarios was performed evaluate methods for reducing grid electricity demand with the goal optimizing renewable usage minimizing environmental impacts. included: (1) conventional, grid-dependent building, followed by (2) addition rooftop photovoltaic (PV) system, (3) PV system lithium-ion battery storage, (4) an ice storage system. Scenarios 3 4 were included this as 16% from overproduced during weekends when unoccupied. results show that 2, 3, reduced operational consumption 33%, 37.8%, 37.9% but increased metal depletion potential 23.9%, 34.4%, 29.0%, respectively. Ice led greatest reduction Efficient production utilization buildings is vital nonrenewable fuel dependence; however, it necessary minimize implementation such technologies.
