The initial phase of the project aims to develop an approach to evaluate and provide a decision support tool for building renovation strategies. In optimising the balance between energy efficiency and renewable energy supply, DREEAM considers a broad scope of technologies within the domains of energy efficiency, renewable energy generation, energy storage, and building management systems.
Considering such a wide range of technology options supports determining and selecting pareto-optimal technology configurations and packages in different building architectures and regions. This approach aims to further encourage the use of technologies that might otherwise not be considered by building owners and renovation design engineers.
DREEAM aims to demonstrate hardware and information interconnections within packages of technologies. In order to achieve this, DREEAM focuses on developing interconnections between currently state of the art systems that have never before been demonstrated together in a real life operational environment (i.e. overall system TRL 5 to TRL 7). In particular DREEAM aims to develop an innovative approach for optimising interconnected energy systems by deploying machine learning building management systems.
The DREEAM approach is being demonstrated in real renovation projects by applying the recommended energy system combinations. These renovation strategies take into account several aspects such as the building owners’ investment strategies, financial standpoint and social considerations. With support from the project partners, the building owners aim to tender the renovation works, which will be performed by constructions companies.
Assessing and monitoring the energy performance of the pilot sites is done throughout the complete project. Monitoring the energy performance at the different pilot sites is a key element as the outcomes feed into the requirements of the monitoring tool, a comprehensive platform for building owners to monitor and control the energy performance for their portfolios of buildings.
One of the project ambitions is to replicate the DREEAM outcomes beyond the pilot sites, at least to 15 locations across Europe. Through a EU multi-city replication programme, the project performs feasibility scans and applies the DREEAM approach in order to update renovation strategies towards Near Zero Energy standards. The aim is to inform decision-making actors, such as cities and social housing owners, of potential renovation options and optimisation potential in the energy renovations through attractive financial packages.
