Changhua Management Office Green Energy Optoelectronics Value-Added Program
“ Office Premises ‘Carbon Reduction and Green Electricity’”

Global warming is getting worse and worse with rapid depletion of conventional energy sources, and with energy conservation and carbon mitigation having been prioritized by all countries in the world. Due to the exhaustion of a limited amount of fossil fuels, the development and use of green energy becomes a trend, wherein solar energy is the most commonly available green energy. The technology used for solar power generation has matured, and the average cost of facilities has become more affordable as well, which is worth vigorously promoting and widely used.

Cooperating with the Bureau of Energy’s “Joint Lease by Tender of Central Ministries’/Departments’ Publicly-Owned Roofs”, green energy was used in office premises. This Office entered the “Joint Lease by Tender of National Central Ministries’/Departments’ Publicly-Owned Roofs”, a lease agreement of solar photovoltaic power generation equipment, with Ming Hwei Energy Co., Ltd. on July 27, 2021, installing solar power generation equipment on the top floor of the rental workstation by cooperating with a photovoltaic company to reduce carbon emissions. It is scheduled to complete the setup before July 31, 2022, and the agreement shall take effect on the validity date (August 1, 2021) and shall remain in full force for a period of 20 years until July 31, 2041.

  This Office has 10 workstations to cooperate with the “Joint Lease by Tender of National Central Ministries’/Departments’ Publicly-Owned Roofs” project for the installation of solar photovoltaic equipment. Seven workstations have been completed up to the present time, and the annual electricity generation will be 310,000 kWh approximately by the time they are fully completed. According to the Bureau of Energy’s announcement on September 27, 2021, the drag coefficient for 2020 was 0.502 kg CO2e/kWh, which reduced carbon emissions by 155,000 kg approximately per year.

When the hot summer comes, the solar photovoltaic system installed on the roof can isolate the unprotected exposure to the sun’s ultraviolet rays, effectively lower the indoor temperature, reduce the office air conditioner electricity cost, delay the aging of the roof building materials, as well as indirectly prolonging the service life of the roof. It reduces carbon emissions, saves expenses and protects the earth.
