Green Schools 2.0 - Energy Smart -
Support Scheme on Replacement of Inverter Air-Conditioners, LED Lighting and Installation of Real-time Energy Monitoring Systems for Schools

  1. “Green Schools 2.0 - Energy Smart” is introduced by the Government of the Hong Kong Special Administrative Region of the People's Republic of China (“Government”) to subsidise and assist primary and secondary schools (except Government and profit-making schools) to replace existing air-conditioners with variable-speed air-conditioners (“VSAC”), convert existing fluorescent lighting / incandescent floodlights into LED lighting / LED floodlights, and install realtime energy monitoring systems (“RTEMs”) at their premises.

  2. “Green Schools 2.0 - Energy Smart” is a Government programme with various new initiatives to foster an environment where teachers and staff can cultivate a positive and green school culture by adopting energy efficient systems and innovative technologies that would be coupled with environmental education programme to encourage the development of environmentally awareness. Major scope of works of the energy saving project includes

    1. replacing existing air-conditioners with VSAC;
    2. converting existing florescent lighting into LED lighting; and
    3. installing RTEMs

    at the premises of non-profit-making non-government primary and secondary schools (thereafter as “primary and secondary schools”). The Electrical and Mechanical Services Department (“EMSD”) will provide subsidy and one-stop services for primary and secondary schools to implement the said energy saving projects in their premises. Under “Green Schools 2.0 - Energy Smart”, EMSD will follow through the entire process of the energy saving projects, including conducting site visits and technical assessments, drawing up design of RTEMs, procuring equipment, installation and commissioning, etc. All the expenses in relation to the installation of the energy saving projects (installation costs and costs of professional services, etc.) will be fully covered by the Government under “Green Schools 2.0 - Energy Smart”.

  3. “Green Schools 2.0 - Energy Smart” is now open for application for implementation in financial year 2022-23.
