2.1. Model Structure
2.1.1. Underpinning Theory of the Model
2.1.2. Previously Developed System Dynamics Model
2.1.3. Supplementary Sub-Model
- A group model building session for experts was carried out.
- A survey was developed and carried out to establish motivations, attitudes and values, contextual or situational factors, social influences, personal capabilities, and habits that can describe and predict energy-efficient behavior.
- A stock and flow structure was built.

3.2. Future Scenarios
- Scenario 1, or baseline scenario, is based on the current ongoing policy in Latvia according to the National Energy and Climate Plan 2030. In 2022, the total available EU funding is 200 million EUR (140 million EUR from the EU Multiannual finance framework and 140 million EUR from the EU Resilience Fund). The support intensity for multi-apartment buildings is 30%. The information is provided by the grassroots information activities via the campaign Let’s live warmer. In addition to that, energy efficiency obligation scheme is used for electricity providers with an annual savings goal of 1.50%.
- Scenario 2 has the same set of policy tools as Scenario 1, but funding is increased three times and is 600 million EUR.
- Scenario 3 has the same amount of EU funding as Scenario 1 and the same support intensity and is combined with other policy tools provided by the interface.
- Scenario 4 has the same amount of EU funding as Scenario 2 and the same support intensity and is combined with other policy tools provided by the interface.
- Scenario 5 has the same set of policy tools as Scenario 4, but funding is increased to 1000 million EUR.
