Periodic Reporting for period 2 - ReCO2ST (Residential Retrofit assessment platform and demonstrations for near zero energy and CO2 emissions with optimum cost, health, comfort and environmental quality.)
Reporting period: 2019-07-01 to 2020-12-31
The RECO2ST project is positioned to address this challenge, through coverage of the entire refurbishment supply chain and encompassing all the stages, from planning and decision making to installation, operation and monitoring.
The project will enable the formulation of customized and efficient renovation action plans and implement cost efficient technological solutions improving the energy efficiency of residential buildings to NZEB levels, through reductions of more than 60% in energy use and at the same time achieve optimal indoor environmental conditions, improving the lives of the inhabitants, and increasing building value for the owners.
The project objectives is:
• To make NZEB refurbishment accessible through novel customizable business models.
• To develop a comprehensive, accurate and accessible Refurbishment Assessment Process delivering refurbishment scenarios customized to end-user needs and applicable to a wide variety of residential buildings made possible by:
• a systemic and integrated NZEB Refurbishment Assessment Platform.
• a method for accurate Refurbishment Planning, enabling accelerated decision making and refurbishment operations through implementation of Integrated Project Delivery (IPD) - reducing the time, cost and complexity of the process.
• a customized retrofit-Kit featuring innovative technologies that will achieve NZEB refurbishment with satisfactory indoor environmental quality for a wide variety of refurbishment scenarios and occupant behaviours.
• Cost efficiency optimization through the identification of the optimal balance point between building energy efficiency measures, indoor environmental quality and on-site renewable energy generation.
• To ensure realization of energy saving measures through cultivating energy-conscious inhabitant behavior, through streamlined and intuitive energy management and through intelligent building interaction with the energy system.
• To achieve substantial improvements of urban microclimate and overall quality of human life by ensuring a healthy, safe and comfortable indoor environment.
• To demonstrate the replicability of the proposed solution through demonstration in varying scenarios.
A Retrofit Kit has been developed comprising the following technologies: Vacuum insulation panels (VIPs); Smart window system; Concentrating Photovoltaic (CPV) panels; An innovative air handling unit (IAHU) system; Two new cool, paint and membrane materials; Nature Based Technologies to reduce particulate matter and VOC concentration and an Intelligent Energy Management System (IEMS) concept with a Graphical user Interface (GUI).
A Renovation Assessment Platform has been developed including improvements of the EOIQR+ tool by a new methodology to calculate renovations costs in all European countries, by integrating a LCA database and by standardization of the building element structure. The developed modular structure of the RAT platform makes it possible to aggregate results of cost, energy savings and life cycle assessment indicators for separate renovations actions as well as for renovation scenarios (combination of actions). The structure includes a least cost methodological approach that in a first stage rank individual renovations actions and renewable energy production options according to their primary energy performance, cost and environmental indicators and in a second stage assess the overall performance of different scenarios by bringing together energy savings and renewable energy production in the same assessment system. To ensure smooth integration of other tools and databases in the platform a data transfer protocol based on the JSON format has been developed. The platform has been tested by users from demo- and early adopter sites.
To further support users in the development of their renovation business cases a Business Model KIT has been developed that address the whole renovation value chain including funding mechanisms and financing schemes. The objective of the Toolkit has been to help owners aiming at renovating large residential buildings or large stock of residential buildings with a view of drastically reducing their carbon footprint. The approach developed was led by the idea that there is a serious gap to bridge between common basic property management know-how and the level required to properly analyse the risks attached to a NZEB renovation and transfer them to the most adequate partner.
A test of the developed business model kit has been carried out at early adopter sites.
Demonstration activities are performed in four multifamily residential buildings located in Cadiz-Spain, Lausanne-Switzerland, London-UK and Frederikshavn-Denmark. Achievements so far has included: Auditing, monitoring and evaluation of performance before renovation as well as, development of renovation scenarios and building interventions. Installation and commissioning of technologies is completed in two of the demonstration cases.
A number of different tasks is carried out in order to support the RECO2ST commercialization. This includes the development of a social adoption plan (completed), analysis of application opportunities in national regulations and standardisation as well as how LCA and LCC calculations, climate change and urban environments can support and/or influence renovation scenario development and decision making.
When the whole RECO2ST approach including the Renovation Assessment Platform, the Retrofit-Kit, the Integrated Project Delivery method, the Intelligent Energy Management System and the Business Model-Kit is implemented in renovation projects, it is expected that the impact will be:
• Reduction of at least 60% in energy consumption in order to reach the target of near zero energy compared to the values before renovation, while enhancing indoor environmental quality
• Decrease of installation time by at least 30% compared to typical renovation process for the building type.
• Demonstration of a high replicability potential and of large market uptake capacity.
• Affordability considering all costs involved, with a payback period below 15 years.
• New generation of skilled workers and SME contractors in the construction sector capable of applying a systemic approach to renovation.
