Since 2019, the university actively urged to apply the subsidy program from Hsinchu City government for the elimination and replacement of energy conservation and the application for the refund of goods tax from the Ministry of Finance (to handle the applications for subsidies for air-conditioner equipment without flue pipe and the application for the tax refund of air conditioner equipment and so on).
