Abstract

The 2018 amended Energy Efficiency Directive updated the policy framework to 2030 and beyond. Through the updated Article 7, EU countries will have to achieve new end-use energy savings of at least 0,8% of their final energy consumption per year after 2020, by establishing energy efficiency obligation schemes (EEOS), or by adopting alternative policy measures. The key rationale of choosing to implement an EEOS is that energy suppliers, retailers and distributors are best placed to identify and achieve energy savings for end consumers, by carrying out measures that improve end-use energy efficiency. In addition, Article 9 was also updated to reflect the need to inform end users on their actual consumption through remotely readable meters or alternative cost-efficient methods, employed especially under heating, cooling and domestic hot water use cases.

The above-mentioned directions will force market actors to put forth initiatives that enable end consumers to monitor and efficiently control their energy use. An excellent contributor to the aims and objectives of the EED is the combination of home-IoT equipment for energy monitoring and management (e.g. smart thermostats) with digital user interfaces for user engagement. The ultimate step is to couple the deployed infrastructure with behavioural measures to promote consumer behavior change and achieve long-term energy efficiency. The proposed combined approach is being tested in a variety of environments, spanning distributed PV prosumers, optimized EV charging and efficient control of Natural gas based heating.

Preliminary results obtained from the use case delivering cost-effective efficiency upgrade of legacy gas boilers, suggest that the combination of home-IoT with digital interfaces and nudging interventions can help meet the updated EED requirements sufficiently, should energy providers and the supporting ecosystem be prepared to deploy the offered solution to end consumers.
