The deliverable D5.2: +Trondheim DST including training manuals/videos was submitted by Integrated Environmental Solutions (IES), with contributions from TK in August 2021. The executive summary of the deliverable is available below and the full deliverable at the end for download:
” This document represents the work completed as part of Task 5.1 ‘Creating the Integrated Baseline Model for Energy/Mobility/Socio-Economic Trondheim’, and as such the task has applied the Decision Support Tool (DST) developed in WP1 (D1.4: Demonstration of the +CityxChange Integrated Modeling Platform) to the Trondheim demo area in the project.
Data was collected relating to the energy performance, demand and supply of 2,818 buildings for the demo district “Knowledge Axis”. These buildings were then simulated in the DST to produce an energy demand baseline for the demo area, and a much more detailed ‘Digital Twin’ model was created for the Sluppen PEB demo area and its buildings in terms of both demand and supply. As well as this, socio economic data for Trondheim was imported into the DST from the latest census results to form a socio economic baseline that will allow future modelling of energy demand/supply changes to be viewed from a socio economic point of view.
In order to demonstrate the functionality of the software, potential energy reduction interventions were applied for the PEB to show how energy demand could be reduced by improving the efficiency of the buildings. Renewable systems (PVs) were also modelled to demonstrate the potential for local supply and energy sharing between buildings to move the PEB towards net zero emissions. Other local generation such as heat pumps is currently under discussion and is therefore not modeled here.
An initial demonstration of the results and training session for relevant people in Trondheim was conducted, and further sessions are planned to ensure Trondheim Kommune can operate and leverage the DST for themselves. The recently developed Online PEB Design Workflow will now act as the main training vehicle to enable this to occur.
Following the training sessions, work is initiated on how to display and make use of the model and DST at screens/interactive screens on the citizen observatories (T5.3) and innovation playgrounds/labs (T5.5), and how TK can make use of the model/DST as a tool and enabler in activities, workshops, and events at the innovation playgrounds. Modelling agreed RES and efficiency interventions and definition of what-if scenarios for use in the shaping of a revised Bold City Vision has not started. Details are discussed in the conclusion. “
