RESUB – RES for urban buildings

An innovative cloud-based platform that enables multi-scale RES integration analysis towards cities’ decarbonisation.

Ifigeneia Theodoridou

Problem definition: Climate change is pushing policy decision-makers to set demanding goals to achieve zero carbon emissions in cities by 2050. Urban buildings account for nearly 40% of global energy-related CO2 emissions. Hence, decarbonizing the urban building stock is of vital importance. Within this framework, it is essential to enable tools that can assess the actual integrated RES buildings’ potential and thereafter enable the calculation of energy production based on each building’s energy profile.

The solution: The RESUB platform is an innovative cloud-based platform that enables private and public investors and energy communities to measure their CO2 carbon footprint and choose the most suitable RES technology. Due to its innovative methodology, it enables RES integration on urban buildings, both on a single-building unit scale, as well as on a large-scale. RESUB is based on a thorough bottom-up approach, that incorporates state-of-the-art technologies, such as Spatial Analysis and Satellite Imagery analysis within a high-resolution GIS system. This is linked to a DSS, containing the relevant geospatial layers that are vital for the current carbon footprint analysis as well as the RES suitability. The aim of this project is to create a cloud-based, user-friendly platform that will accelerate the introduction of RES in the urban built environment, enabling cities’ struggle toward energy independency.

RESUB builds upon existing developed technologies and on the Re-Polis platform, a co-funded project called “Development of an integrated cloud-based platform for the holistic assessment of the energy and environmental footprint of urban buildings - Re-Polis”. Re-Polis was funded within the framework of the action "RESEARCH CREATE INNOVATE" of the Operational Program Competitiveness, Entrepreneurship and Innovation 2014-2020, which will be finished within June 2023.

Scientific impact: The development of RESUB represents a powerful, pan-European, web-based tool, that incorporates an innovative DSS, which will accelerate developments concerning cities’ decarbonization, by boosting both the scientific community’s as well as the private sector’s involvement. Furthermore, the private sector now can securely assess and design holistic, custom-built decarbonization measures at the municipal level in a shorter period of time.

Social impact: Fuel poverty is a major problem that Europe needs to tackle. RESUB is the optimum tool to assess the needs and design the optimal tailor-cut solutions for RES integration in the urban built environment to create energy-just cities.

W4RES partner HFT Stuttgart supported this project with its expertise in building modeling and building simulation. The special focus lies on the simulation of PV potential and the refurbishment/retrofitting of buildings.
