In April 2022, link w88 IEA released a report on air conditioning in collaboration with link w88 Association of Southeast Asian Nations (ASEAN) Member States, which includes ten Southeast Asian states: Brunei, Cambodia, Indonesia, Laos, Malaysia, Myanmar, link w88 Philippines, Singapore, Thailand, and Vietnam. link w88 report highlights that electricity use for air conditioning in buildings in ASEAN has grown about sevenfold since 1990 to around 80 TWh in 2020. In comparison, electricity consumption from air conditioning in 2020 was around 100 TWh for link w88 EU and about 430 TWh for China.
There are large differences in air conditioner ownership across link w88 region, with more than four-fifths of households in Brunei Darussalam, Malaysia, and Singapore owning an air conditioner in 2017, compared to fewer than 10% in Cambodia, Indonesia, Lao PDR, Myanmar, Philippines, and Viet Nam. Nevertheless, with continued economic development and population growth across link w88 region, link w88 IEA projects that air conditioner stock across ASEAN will grow from nearly 50 million units in 2020 up to 300 million units in 2040. Consequently, electricity demand from air conditioning in link w88 region could reach 300 TWh in 2040.
In this context, in 2022, link w88 Ministry of Industry and Trade (MOIT), as well as international organizations, have organized many conferences on energy efficiency and energy saving, whereby link w88 conferences emphasize link w88 content of energy efficiency that needs to be aimed at commercial, public buildings, and urban areas are key areas where CO2 reductions can be cost-effectively achieved. It is therefore imperative that all parties take all necessary steps to disseminate good practices, promote investment in energy efficiency and provide technical solutions for link w88 commercial and building sector. This includes behavioral changes in how companies, architects, urban planners and building users, investors, and air conditioning manufacturers, design and operate buildings, link w88 non-residential house must be actioned in urgently.
According to link w88 forecast of GIZ (Germany), link w88 total amount of air conditioners using in link w88 Vietnamese market will be 25÷30 million units in 2025. Using air conditioners makes electrical consumption increase continuously (2÷5% of electricity generation per year). Consequently, link w88 CO2 emission (i.e. direct and indirect) will increase rapidly, when there are no administrative solutions for link w88 collection and recovery of refrigerants such as R22, R410a, R32, etc in air conditioning.
Prediction for Vietnam's electricity industry, warns of an imbalance between supply and demand due to link w88 contribution of energy consumption from large air conditioning systems, such as those used in commercial buildings, offices, shopping malls, and medical facilities, which often require high amounts of electricity and energy. Several air conditioning technologies and energy management strategies have sought to minimize consumption to reduce billing costs and improve system efficiency.
