Growth in the Asia and the Pacific has resulted in increased demand for building floor area and energy consuming services. As an indication, in 2018, the building sector of the Association of Southeast Asian countries, the People’s Republic of China (PRC) and India, accounted for 27% of their combined final energy use and 24% of their energy related carbon dioxide emissions, excluding emissions from manufacturing building materials. Energy demand is projected to almost double in Asia and the Pacific by 2030. New building construction in the region is expected to represent nearly half of the world’s total by 2040. 

Demand-side energy efficiency can be as valuable as controlling energy from its supply end. These could consist of both technological and behavioural change leading to savings in energy consumption without reducing consumer needs and level of comfort.  In this, the government’s role is crucial for setting up the appropriate policies, programs, and incentive mechanisms to create a conducive environment that will encourage utilities, consumers, and other market players to increase their demand-side energy efficiency efforts. Measures such as managing the demand curve by utilities, like load shifting to level-off peak demand, and many new innovative technologies, solutions, and business models for energy efficiency in buildings, residences, among others are already available. These may be adopted by both the public and private sectors given the right investment conditions.

The potential of energy efficiency, especially end-use energy efficiency in buildings, in Asia and the Pacific remains high. Many countries in the region that have taken determined measures to systematically address energy efficiency in their policies and regulation have demonstrated declining energy intensities. According to the International Energy Agency’s World Energy Outlook 2019, energy efficiency and the decarbonisation of electricity in Asia has the potential of reducing annual emissions from buildings in 2040 by almost 3,000 megatonnes of carbon dioxide. Material efficiency could bring significant additional reductions in greenhouse gas (GHG) emissions in the material lifecycle of buildings, with potential reductions of over 80% in the PRC and 50% in India for residential buildings. 

This track will discuss the challenges of energy efficiency and how to create an enabling framework for promoting efficiency gains on the demand-side to save costs, reduce air pollution and curtail carbon footprint, by way of advanced clean technologies and solutions and the use of innovative business models and financing instruments.


The track session aims to:

  1. Assess the issues and challenges and discuss the prospects of demand-side energy efficiency in buildings in Asia and the Pacific.
  2. Present policy trends, innovative energy efficiency solutions and technologies and best practices that are applicable to ADB developing member countries (DMCs).
  3. Discuss the critical role of governments and how it can lead in creating an enabling environment for the adoption of demand-side energy efficient solutions through, the financing of large public programs that create markets, demonstrate technology applications, and create an ecosystem of service providers.
  4. Present processes in developing and designing viable business models and financing solutions to increase uptake, and replication of demand-side energy efficiency in buildings among ADB DMCs.

Target Participants

Government officials from the ministries of energy, environment, health, building and construction, and housing; financiers; private sector; academia; researchers; and non-government organizations from ADB DMCs.

Session 1

Policy, Strategy, Role of the Public Sector

Presentations on the demand-side energy efficiency scenario in Asia and the Pacific against the SDG7 include status, issues, trends, and prospects. Focus is given on polices, strategies, and the roles of the public sector in encouraging the uptake of energy efficiency measures.  

Discussions will cover building a business case for energy efficiency in public buildings, developing policies and regulations that would create a conducive environment for private sector to come in, existing policy and regulatory trends that have been proven effective, and best practices that may be adopted by developing countries and other stakeholders for promoting demand-side energy efficiency solutions.

The moderator introduces the session and its speakers and highlights the session's objectives.
