4E (Energy Efficient End-use Equipment) technology collaboration programm
The Energy Efficient End-Use Equipment (4E) Technology Collaboration Programme is an international platform under the International Energy Agency (IEA) that supports governments in designing, implementing, and harmonizing policies to improve energy efficiency in appliances, lighting, and equipment. Through research, data sharing, and comparative analysis, 4E helps member countries coordinate minimum energy performance standards (MEPS), labelling schemes, and test procedures across global markets. It focuses on end-use products with significant energy demand such as air conditioners, heat pumps, lighting, and motors.
The programme supports participating countries in developing robust monitoring, verification, and enforcement (MVE) systems and advancing test methods that reflect real-world energy use. It also conducts policy impact assessments and develops guidelines for harmonized performance standards.

Assessing Clean Energy Opportunities Through Demand Aggregation in Bengaluru’s Apartment Buildings
The study focuses on energy efficiency (EE) and rooftop solar (RTS) for apartment complexes. Passive cooling aspects are indirectly relevant through EE measures that reduce internal heat gains and optimize energy use, lowering dependence on active cooling. No direct passive cooling strategies are discussed.

Assessment of Skills and Knowledge Gap in Energy Efficiency within the Building Sector in Argentina
Focuses on identifying skills and knowledge gaps in Argentina’s building sector to implement energy efficiency measures, including thermal envelopes and efficient heating systems. While not exclusively passive cooling, improving building thermal performance directly supports reduced cooling demand. Recommendations target capacity building for professionals and regulatory support to scale energy-efficient buildings.

Bridging the Cooling Gap: Energy Efficiency as a Driver for Appliance Access
The Bridging the Cooling Gap research report quantifies how improved energy efficiency standards can accelerate access to cooling appliances and equipment. Using long-term policy scenarios, the study estimates how doubling the efficiency of room air conditioners, fans, and refrigerators by 2030 could cut lifecycle costs by around 60%, enabling hundreds of millions of additional people to afford them. In India, Indonesia, and Nigeria, this would mean expanded access for over 500 million people by 2050, while consumer savings could exceed $275 billion annually. The report also finds that efficiency-driven access would avert more than 420,000 premature heat-related deaths, improve resilience to extreme heat, and limit the growth in electricity demand, showing that ambitious efficiency policies can deliver climate, health, and equity benefits simultaneously.

Caribbean Cooling Initiative (C-COOL)
The Caribbean Cooling Initiative was initiated in 2018 to transform the cooling markets in select Caribbean countries (Bahamas, Barbados, Dominican Republic, Jamaica, and St. Lucia) by promoting energy-efficient and climate-friendly refrigerators and air conditioners. It includes a market assessment of existing stock and projected growth; development of national cooling strategies; technical assistance for MEPS and labelling; financial mechanism pilots to lower upfront cost barriers; capacity building and stakeholder engagement throughout the supply chain. For users interested in shaping policy, this resource provides data on projected electricity savings, emissions impact, policy levers (e.g. performance standards, financial incentives), and examples of how tourism-heavy economies can benefit from improved cooling efficiency.

Ceiling Fans Savings Potential Assessment
This assessment estimates the potential electricity, cost, and carbon emissions savings from implementing Minimum Energy Performance Standards (MEPS) for ceiling fans in fourteen countries with reliable sales and stock data. It compares three scenarios: Business As Usual; Minimum Ambition (applying U4E’s baseline MEPS starting January 2023); and High Ambition (applying the highest efficiency levels in the guidelines). Using country-specific data on fan efficiency, airflow, hours of use, service value, and stock turnover, the report shows how stricter MEPS can reduce electricity use significantly by 2040, lower consumer electricity bills, and avoid substantial CO₂ emissions. This resource helps governments, standards bodies, and energy agencies see what gains are possible, design MEPS for ceiling fans, estimate national savings, and justify implementation of efficiency policies.
