New report highlights global energy efficiency progress

A new report from the International Energy Agency (IEA) shows that energy efficiency progress recovers in 2021 but needs to double for net zero by 2050.

Energy efficiency progress is too slow

According to the IEA, global energy demand is expected to increase by about 4% in 2021, returning to pre-pandemic levels as economic activity rebounds. The previous year was one of the worst ever for efficiency improvement, as energy demand and prices fell, technical efficiency enhancements slowed and the balance of economic activity shifted away from less energy-intensive services, such as hospitality and tourism. The report states that Covid-19 has disrupted global energy and economic trends in 2020 and 2021. Accordingly, it is still unclear whether this year’s improved energy intensity is a valid indicator of a sustained recovery. However, increased investment trends, rising government spending on efficiency, and stronger political climate ambitions offer some encouraging signals.

Government policies lift efficiency investments in the buildings sector

In 2021, efficiency investment is expected to rise by 10% reaching now almost USD 300 billion. However, to align with levels foreseen in the IEA Net Zero Emissions by 2050 Scenario, overall annual investment needs to triple by 2030. Moreover, the recent investment growth induced by government policies has been concentrated largely in Europe, suggesting polices are needed in other regions to achieve global climate goals. Looking at 2020, stronger buildings efficiency programs in Europe compensated for transport, where Covid-19 pushed down total spending. IEA reports that transport efficiency investments are now recovering while buildings investments are reaching record highs.

The building sector is key to reaching net zero target

The Net Zero Emissions by 2050 Scenario involves more than 40 energy efficiency milestones. Without these, total final energy consumption would be a staggering 30% higher by 2030. The good news is that IEA states that most of the milestones incorporate technologically mature solutions that can be scaled up very quickly. In the scenario, energy efficiency actions in the buildings sector deliver some of the greatest energy savings through to 2030. Increasing the share of existing buildings that are zero carbon ready from less than 1% today to around 20% by 2030 is a key milestone.

Bringing down HVAC energy for net zero buildings

HVAC solutions in buildings are a good starting point for making buildings more energy efficient. Looking at available data, hybrid and natural ventilation has shown to significantly reduce energy consumption compared to mechanical installations. Using IoT and intelligently connected solutions that offer enhanced monitoring and control of energy use can deliver energy savings of 20% to 30%.
