Establishing an Integrated Monitoring Concept for the Vienna Lighthouse Project Smarter Together
2019
Within the EU Lighthouse Project “Smarter Together”, the City of Vienna has been working during the last
three years together with the Cities of Munich and Lyon following a P2P learning process to implement a set
of integrated smart solutions with focus on holistic buildings refurbishment for low energy districts, onsite
renewable energy supply (RES), e-mobility solutions and ICTs. This endeavour aims to support the city's
vision to transform Vienna into a sustainable, resilient and liveable city along the ongoing urban
transformations and energy transition.
For several demonstration site projects an integrated monitoring concept has been established and tested
within a co-creation process encompassing key city stakeholders and various actors from research
institutions, industry and building contractors. The developed concept comprises the whole automated
process of sensor-based data collection, transfer to, and storage on the city’s Data Management Platform
(DMP) and the subsequent processing, visualisation and generation of related key performance indicators
(KPIs). The KPI-based monitoring process seeks to track and monitor the impacts of the implemented
solutions for the city demonstration sites, besides their potential contribution to achieving the city’s
sustainable development targets following an intracity rollout phase and a future replication plan in selected
follower cities.
The established process highlights the importance of intensive communication among all stakeholders. The
generated KPIs for the refurbished buildings demonstrates the importance of establishing a co-creation
process gathering building owners, construction companies, city governance, research institutions and ICT
utilities responsible for developing and maintaining Vienna’s DMP and the following provision of smart
services to third parties.
The KPI-based monitoring shows that for the use cases of building refurbishment (comprising 65060 m2
of
social housing and 3800 m2
public building) the achieved energy saving by building efficiency measures will
reach annually about 4760 MWh. The fossil fuel saving through substitution effect by onsite renewable
energy generations (PV, solar thermal, geothermal heat pumps) will reach about 451 MWh. The resulting
CO2 reduction by building energy saving and RES will reach about 1423 tCO2 annually. The results
underline the importance of the implemented smart solutions in achieving the Vienna Energy Framework
Strategy pursuing a clear decarbonisation path and thus supporting its transformation vision towards an
inclusive, sustainable and liveable city.
The deployment of the successfully implemented and monitored solutions is ongoing. Based on the lessonslearned and the gained best-practices, it is expected that the implementation of an appropriate replication
plan will make it possible that by the year 2030 a significant part of the existing old social buildings in
Vienna will be refurbished and monitored following the integrated monitoring concept established within the
Smarter Together project.
