                    abstract = {It is urgent that the built environment transitions towards renewable energies and adopts ambitious renovations strategies as both are unavoidable steps towards long term sustainability goals. While extensive research has been focused on the integration of buildings in renewable energy production networks as well as on renovation measures such as thermal insulation and installation of heat-pumps, it is still unclear how these actions perform at scale when combined together. To fill this gap, this paper introduces the digital platform Open-data for Building Energy Efficiency, Renovation and Storage (OpenBEERS) that allows simulation of renewable energy deployment scenarios at the urban scale to help municipalities and energy professionals plan transition strategies effectively. The platform combines the state-of-the-art CitySim physics-based solver with the BASOPRA optimization framework allowing us to assess the techno-economic feasibility of distributed energy resources (DERs), including heat pumps and electric vehicles (EVs). Out tool integrates a 3D interface for the visualization of the input and output data. Our approach is validated with three case studies, municipalities in the State of Valais where a detailed analysis of DERs deployment scenarios is conducted.}
