The project aims to unlock the nZEB renovation market increasing property value through a new systemic approach to retrofitting that will include innovative components, processes and decision making methodologies to guide all value-chain actors in the nZEB building renovation process; including a specific knowledgebased tool for Real Estate Industry to select the integrated solutions with highest impact in the revalorization of the building. These will contribute to create a large-scale nZEB renovation Market in Europe transforming the residential building stock to match the net-zero energy standards at affordable price. To achieve this strategic target, we have identified four main pillars upon which will be supported the project:
1. Reduce energy consumption while increasing the share of renewable energy in buildings. The two nZEB principles.
2. Affordability, reducing the life cycle cost with a significant decrease of installation time and an energy performance optimization. Cost & risk reduction with low disruption during building renovation, to attract customers interest.
3. Maximize the capacity of replication of the developed concepts and methods for integrated sustainable renovation. The replicability and adaptability through modularity, as a strategy to capture a large-scale renovation market.
4. Maximize the revalorization of existing buildings in the short-medium-long term, through a value-based decision making methodology that include the post-retrofitting value of assets and savings but also visualize the dynamic-evolution of the property values for the near future as trigger of the new large-scale nZEB renovation Market.
Based on these 4 pillars a series of objectives and targets will be achieved. Objectives that imply a deep analysis and the consequent innovation in the current processes of renovation. All technical, environmental, financial, social and market objectives are aligned under these 4 strategic objectives and will serve to design the structure of work-packages/tasks and the relationships, links and feedback loops, as well as the selection of partners and resources. The RENOZEB system developed by this project implies a change in the current renovation processes (off-site construction, tight coupling among multiple stakeholders -envelope designer/manufactures/HVAC expert, richer data flows, new value framework). Consequently, the project will develop not only specific solutions affecting the envelope or the HVAC energetic system, or the integration of RES, but also we will develop the RenoZEB methodology to support the stakeholders in the success adoption and valuation of the proposed solution. To facilitate the deployment of this methodology, RenoZEB will develop an ICT open and real collaborative platform to support the renovation process from the planning to the management stage. The integrated solution and the implementation process developed, will be complemented with the design of a methodology to improve the decision-making process for selecting the best strategy of renovation oriented to answer the needs of public and private Real Estate industry. This holistic approach will contribute to go beyond the laboratory or experimental test to reach the maximum replicability in a potential large-scale market.
