Summary of "Scaling up Energy Efficiency in Buildings" for Uzbekistan

Core Content

This report, prepared by the World Bank, focuses on scaling up energy efficiency (EE) investments in residential, commercial, and public buildings in Uzbekistan, particularly in the context of space heating. It outlines opportunities, barriers, and recommended actions for improving EE in these sectors, with a special emphasis on reducing natural gas consumption and enhancing compliance with EE standards.

Main Objectives and Scope

Objective: To identify scalable EE interventions for the next 3–5 years to support Uzbekistan's energy efficiency goals.
Scope: Focuses on three priority areas:
1. Replacing nonstandard and inefficient gas boilers in detached homes and small commercial buildings.
2. Scaling up EE investments in public buildings, particularly education and health care facilities.
3. Improving compliance with building EE standards in new constructions.

Key Opportunities

1. Natural Gas Savings in Existing Buildings

Residential, commercial, and public buildings account for 65% of natural gas final consumption.
The average specific energy consumption in residential buildings is 290 kWh/m², significantly higher than the 95 kWh/m² in the Netherlands, which is similarly reliant on natural gas.
Nonstandard gas boilers (often homemade) are widespread and consume 50% more gas than modern industrial standards.
Estimated annual gas savings from replacing nonstandard boilers with efficient ones could reach 2.4 billion m³, or 13% of total gas consumption in these sectors.

2. Energy Efficiency in New Buildings

Building EE standards were introduced in 1997 and updated in 2011, but compliance remains low.
New detached houses (99% of new residential construction) are the main focus for improving EE standards.
Enforcing EE standards in new buildings could reduce heat energy demand by 50% compared to non-compliant buildings.

3. Public Buildings (Education and Health Care)

Public buildings account for 85% of the total public building stock in Uzbekistan.
Inefficient boilers and poor insulation are common, leading to high energy consumption.
Pilot projects showed energy savings of over 40% in space heating for these buildings.
Estimated investment needs for thermal renovation of public buildings are up to US$1 billion, with 80% allocated to educational facilities.

Main Barriers

1. Residential and Commercial Space Heating

Low domestic gas prices reduce the incentive for upgrading.
High cost of modern boilers compared to nonstandard alternatives.
Lack of awareness among residential consumers about the benefits and costs of EE.

2. Public Buildings

Lack of dedicated funding and a revolving financing mechanism to capture energy cost savings.
Low energy tariffs lead to long payback periods for EE investments.
Inadequate legal and regulatory frameworks for energy performance contracting.

3. New Buildings

Underdeveloped supply chain and compliance system for energy-efficient buildings.
Decentralized construction market, especially in rural areas, makes enforcement difficult.
Weak incentives and lack of credible cost-benefit information for complying with EE standards.

Key Recommendations

1. Residential and Commercial Space Heating

Option 1: Introduce a cash incentive program for replacing nonstandard boilers with efficient ones.
- Provides a clear market signal.
- Requires government administrative support.
- Should be a temporary measure until gas prices and boiler costs align.
Option 2: Establish a dedicated consumer credit line for EE upgrades.
- Similar to current industrial EE credit lines.
- Reduces borrowing costs for households and businesses.
- Can be expanded to include other EE measures like window and roof insulation.

2. Public Buildings (Education and Health Care)

Create an Energy Efficiency Revolving Fund (EERF) within the existing off-budget fund.
Focus on energy service agreements (ESAs) to finance EE projects in education and health care facilities.
Encourage private sector involvement in providing energy-saving services through public procurement.

3. New Buildings

Review and improve compliance enforcement processes.
Promote mandatory energy performance standards for building materials and components.
Coordinate international donor activities for demonstration projects and technical support.
Develop a schedule for revising building EE standards and a mechanism for stakeholder engagement.
Engage manufacturers to expand the market for energy-efficient products.

Role of International Financial Institutions and Donors

Provide financial assistance in the form of loans and grants.
Offer technical assistance for capacity building among key market participants and the government.

Conclusion

Uzbekistan has significant potential for improving EE in buildings, particularly in space heating.
Domestically available technologies can achieve substantial energy savings.
Overcoming financial, institutional, and informational barriers is essential for scaling up EE investments.
A combination of policy support, financing mechanisms, and awareness campaigns is required to drive EE improvements in the short to medium term.
