Making the existing real estate more sustainable is one of the biggest challenges that construction currently faces. Although the need is on the minds of almost everyone, there is often still a barrier to initiating such large-scale renovations. The lack of real evidence of the energy savings to be achieved, cost reduction and an improved indoor environment makes the construction sector hesitant to take the step towards large-scale sustainable renovation. The European Horizon2020 research project P2Endure now ensures a thorough substantiation of the results to be achieved and makes a good, objective assessment possible.
DEMO is involved in the P2Endure as project coordinator and as a knowledge partner in the field of real estate creation and management. P2Endure focuses on large-scale renovation and transformation based on prefabricated plug-and-play solutions and BIM. P2Endure examines the entire renovation process and investigates how this can be optimized. First of all, taking stock of the current real estate object, then modelling, actually renovating it and ultimately monitoring the results. Where the monitoring is used again to further optimize the renovation process.
At the moment, the P2Endure project is halfway through the four-year term. We are happy to provide an update on the development of the software tools, which help to take stock of the as-built situation and that support in making optimal choices for both renovation and transformation.
To make optimal choices for renovation, we need the following information:
- the cost of renovation or transformation (CAPEX),
- and the expected maintenance costs (OPEX),
- the calculated energy consumption for the chosen renovation variant (OPEX),
- the (increased) revenues from exploitation.
Through the software tool in RE Suite, the renovation variants can be compared from a financial economic point of view. The various prefabricated plug-and-play solutions can be compared to traditional renovation and to the situation where renovation would not take place. The total lifetime costs (LCC) can be mapped on the basis of the ISO NEN 15686-5 standard. Other criteria can be added via the RE Dashboard in order to be able to make decisions on not purely economic criteria. Think, for example, of comfort, health, environmental impact materials, cultural value of the building and disruption of residents and users during the renovation.
For the necessary input in the field of energy, P2Endure develops a structure in which the various Plug-and-Play renovation solutions can be made available in a library and which can be applied in the various renovation variants based on their parametric properties.
In order to realize all this, a BIM model of the existing building is needed supplemented with the condition scores. In P2Endure, our condition measurement software tool (RE Maintenance) has been further developed, not only as a reliable and accurate method for recording the technical condition and the required maintenance measures to extend the service life, but also to serve as the basis for large-scale renovation and transformation. The advantage for the building owner is that all information from and about the building is now collected in one information model. This model can again serve as a starting point for renovation and transformation decisions. More than ten demonstration cases will monitor the performance of this innovative large-scale renovation approach and the results will serve as an 'evidence-based' decision-making basis for sustainability policy.
More information about the P2Endure project and the various demonstration cases can be found on our website. Can we support you in making choices in the field of creating and managing real estate? Please contact us: call 015-7502520 or email info@demobv.nl
