REDUCING ENERGY CONSUMPTION IN A KEY SECTOR

The construction sector is the highest energy consumer (about 40%) and main contributor to GHG emissions (about 36%) in Europe. At this stage, tackling the refurbishment of existing residential buildings is a top priority and decarbonisation is the main goal aligned with the European energy and climate change policies.

The REZBUILD project is mainly aimed at creating a collaborative refurbishment ecosystem focused on the existing residential building stock. Nowadays, the Near Zero Energy Building (NZEB) renovation methodologies are required as one of the key enablers supported by Horizon 2020 Framework Programme in order to promote business research and innovation through energy-efficient buildings.

REZBUILD will address these challenges by opening the construction sector with the integration of innovation technologies in order to pave the way towards an annual renovation rate of 2,5% instead of current rates lower than 1%.

This project is awarded by the European Commission with a H2020 programme Grant of € 6,996,128.25  and a total budget of € 9,038,208.75. REZBUILD started in October of 2017 and will run for 4 years.

THREE OBJECTIVES FOR A UNIQUE PROJECT

THREE OBJECTIVES FOR A UNIQUE PROJECT

COLLABORATION, ADVANCED TECHNOLOGIES

AND NEW BUSINESS MODELS

Besides its main objectives the REZBUILD project is aimed at achieving the following specific goals:

  • A multi-collaborative refurbishment ecosystem as an accessible platform
  • Develop and demonstrate the first set of cost-effective advanced technologies for housing retrofitting based on Key Enabling Technologies (KETs) and on advanced BEMS for a reduction of 60% in energy consumption, enhancing indoor environment comfort in three different housing typologies.
  • Provide the first retrofitting plan as a systemic methodology, by selecting the best retrofitting technology package as a tailored plan through a single interactive platform specification, fully-integrated with the value chain actors.
  • Decrease the installation time related to the whole building renovation value chain by 30%.
  • Define new business models to accelerate the refurbishment of existing building stocks putting special emphasis on the maximum payback time of the solution below 15 years, attracting new investors.
  • Define and design guidelines and propose specifications for new EE procedures interconnecting with final consumers.
  • Provide new training procedures focused on decentralized construction models and development of new high-skilled jobs according to the Europe 2020 challenges.

EXPECTED RESULTS

The REZBUILD project is based on the provision of a collaborative refurbishment ecosystem easy to be customized and implemented according to the diverse building renovation rates in any European country or even beyond European borders. It will result in the following main expected impacts:

  • 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 improving indoor environmental quality.
  • Decrease the installation time by at least 30% compared to typical renovation process for the building type.
  • Demonstration of a high replicability potential and a large market uptake capacity.
  • Affordability considering all costs involved, with a payback period below 15 years.
  • New generation of skilled workers and SME contractors capable to apply a systemic approach to renovation

IMPACTS

The REZBUILD project contains an effective approach to provide both benefiting environmental, social and economic impacts.

ECONOMIC IMPACTS

1   Modernise EU economy by grinding down GHG while creating jobs and growth

2   The EU as the World Leader on Renewable Energy and placing Energy Efficiency first based on new technologies and Industrial Leadership

3   Ensure a Socially fair transition where regions, cities and consumers play an active role

4   Mastering the renovation of the main existing building typologies in Europe, with ambitious, cost-effective and holistic refurbishment packages

5   Reducing the construction and maintenance costs of new NZEB

6   Making Energy Efficiency works in new and existing buildings less costly and less disruptive for occupants

7   Closing the gap between predicted and measured energy performance for new and refurnished buildings

ENVIRONMENTAL IMPACTS

The amount of buildings that are refurbished every year is hindered by a fragmented sector, with many SMEs, technologies and platforms involved along the value chain. Additionally, ownership is dispersed within large housing buildings, leading to small-scope one-tenant retrofitting decisions, while an aligned retrofitting plan would provide better results for the building as a whole. REZBUILD concept will increase the refurbishment rate, allowing refurbishes a greater amount of energy inefficient buildings. This approach will be developed through the application of key sustainable construction principles during the renovation such as the reduction of demolition waste by recovering, reusing and recycling materials, dust-minimizing techniques or careful clean-up. Additionally, the selection of products will consider environmental labels in the field of ecodesign, low carbon footprint, EE labels or renewable raw materials.

Many currently refurbished buildings are still far from the NZEB target due to small scope retrofitting plans or difficult accessibility to financial sources. The REZBUILD platform will increase the refurbishment depth, enhancing the level of energy or GHG emissions savings achieved per refurbishment action. In other words, the IA expects to reduce the energy consumption of 2,830,430 kWh in the demo buildings cutting 158.15 tn/CO2 (558g kWh/g CO2)26.

SOCIETAL IMPACTS

The project will directly increase the competitiveness and sustainability of the European construction sector and will contribute to reinforce its level of  employment in it, as well as improve the qualification of workers towards more technical and engineering profiles.

The societal impact of the project is not only seen in terms of employment, but also in terms of social sustainability.

Preparing the next generation of workers in using new technologies: current construction sector workers are able to and will be trained to use the solution, minimizing their work for low-tech on-site works. Furthermore, the construction sector will become more attractive for high-skilled workers through the industrialization of an important part of its operation. This will stimulate social cohesion by developing value added production with the sector, thus demanding for higher educated workers and  higher salaries and allowing the maintenance of European wage relations.
