This Digital Twin tool supports city councils and municipalities in evaluating, planning, and optimizing the energy performance of buildings. It enables a current assessment of building envelopes in terms of thermal transmittance and models the impact of residential energy systems, helping cities to reduce energy consumption and monitor CO₂ emissions at the district level.
The tool includes two main modules that work together to support energy transition and climate resilience efforts:
- Greenhouse gas (GHG) Emission Balance Tool
- Energy Profile & Planning Module
Together, they offer advanced simulations and environmental impact assessments to support building retrofitting, energy planning, and climate action.
By making this information publicly accessible, the tool empowers both local authorities and citizens to make informed decisions, contributing to healthier and more equitable urban environments.
In Istanbul, the Integrated Digital Twin tool directly contributes to the city's carbon neutrality strategy by providing detailed GHG balances for various renovation actions and scenarios, evaluating energy consumption reductions resulting from thermal and system upgrades, and offering projections for 2030 and 2050 to support future-proof city planning. The tool enhances urban resilience by helping reduce upfront investment risks for renewable energy and energy efficiency measures through quantitative scenario analysis. Aligned with the principles of a Just Transition, it leverages digital technologies to support open-access data and energy pattern mapping, making sustainable urban planning more inclusive, transparent, and equitable.
