Renovation Decision Support System (RenoDSS)

Responsible Partner

Xylem Technologies

RenoDSS provides an accurate estimation of the energy, cost, and environmental impact trade-offs of alternative renovation scenarios. The estimation of post-renovation energy consumption is based on energy data models, structural and geometrical properties of the building, materials, HVAC systems, residents’ usage profile, as well as weather data. RenoDSS also takes the environmental impact of the renovation and the interaction with surrounding buildings into account. All KPIs and details of possible renovation scenarios are shown in an intuitive user interface which enables the renovation designer to select the optimal renovation scenario in terms of costs, energy consumption, and environmental impact.

Synergies with other BIMERR tools

RenoDSS retrieves all input data from the BIMERR Interoperability Framework (BIF) and an provides output data via the BIF to selected BIMERR components (e.g., PWMA).
Relevant BIMERR Use Cases
  • UC-03 (Adapt design to the actual building use, including accurate information about occupancy and schedules, comfort requirements/ preferences and energy uses)
  • UC-13 (Perform back-to-back simulations of alternative renovation scenarios to evaluate and select the best energy-performing renovation scenario)
  • UC-14 (Energy performance assessment to be elevated at a life-cycle perspective including relevant LCA-LCC metrics)
  • UC-15 (Energy performance simulations to assess not only energy metrics, but also accurately evaluate occupants' comfort and indoor air quality)
  • UC-16 (Assessment of energy performance to also address the district aspect and enable the consideration of interactions between buildings, but also between buildings and district systems in a holistic assessment framework incorporated in urban planning applications)
Development Roadmap
The first version of RenoDSS will be officially issued on M22 to support the pre-validation deployment and testing activities, while their final version will be delivered on M30 to evaluate their performance in real renovation projects (validation phase).
