“ADAPTABLE INDUSTRIALISED ENVELOPES” Workshop Context

On the need of industrialised solutions for the renovation of existing buildings:

The main objective (the renovation of the building stock, of which in Europe, a large share (approximately 34%) of the suburban multi-storey residential buildings is built between the 60’s and the 80’s, when there were only few or no requirements for energy efficiency. Such a big figure should represent a consequent sizeable market, though the amount and the innovative aspects of technologies are limited. These limitations can be explained as coming from different barriers (source: LEAF project)

 ROI usually quite high

 Difficulty to test the solutions on real buildings due to regulations, insurances…

 Funding: no easy way to obtain funds to renovate

 High numbers of stakeholders that exacerbate the retrofit challenge

 Split incentives to appropriate the benefits of the savings

“ADAPTABLE INDUSTRIALISED ENVELOPES” Workshop Agenda

The session will then allow an open discussion on the topic of the innovation for the energy efficient renovation of existing residential buildings by means of prefabricated modules in Europe and especially social housing. The objective will be to determine how to improve the capacity to innovate with prefabricated elements for the energy renovation of existing building. The debate will tackle the following issues:

 European regulations

 The necessity of testing on real cases

 Stakeholders involvement and acceptance

 From innovation to business

 Presentation of each technologies (E2VENT, BRESAER, BERTIM, BIOFACADE): Concept, Progress, Challenges

 Open discussions with the room on the concepts 

 Discussion on “how to improve the capacity to innovate with prefabricated elements for the energy renovation of existing building” and “European regulations, The necessity of testing on real cases, Stakeholders in-volvement and acceptance – From innovation to business.”


“ADAPTABLE INDUSTRIALISED ENVELOPES” Workshop Outcomes

This workshop clustered some EU funded projects to present and discuss market characteristics surrounding FOUR innovative technologies that represent potential breakthroughs in the field of prefabricated façade modules for the renovation of existing buildings.

This workshop also produced a subsequent report on the barriers to the innovation in the field of modules for the façade renovation of existing buildings. Finally, knowledge transfer from the project workshop speakers the to the attendees of the Sustainable Places 2016 international con-ference will facilitate the broadening of construction stakeholder views and opinions into the user requirements process ongoing in the projects.

Workshop Co-Chair: BERTIM

BERTIM will develop a prefabricated solution which will provide the opportunity to renovate improving energy performance, air quality, aesthetics, comfort, and property value at the same time, while ensuring low intrusiveness during renovation works. BERTIM project wants to contribute to increased energy efficient building renovation rates in Europe by means of developing energy efficient and cost-effective products for the wood industry.

BERTIM partners will analyse the possibility of increasing the density of existing urban structures by means of adding roof floors. The increase of density is already an urban strategy for sustainability of resources, and to foster this trend the model will allow to building owners to have at their disposal new dwellings to be sold. An investor could also be interested in investing in the renovation in exchange of the new dwellings. The technical social and economic barriers will be analysed, and a technical solution to increase one floor with timber 3D prefabricated modules will be proposed

Workshop Co-Chair: E2VENT: “Energy Efficient Ventilated Facades for Optimal Adaptability and Heat Exchange enabling novel NZEB archi-tectural concepts for the refurbishment of existing build-ings” [www.e2vent.eu]

E2VENT will develop, demonstrate and validate a cost effective, high energy effcient, low CO2 emissions, replicable, low intrusive, systemic approach for retrofitting of resi-dential buildings, able to achieve remarkable energy savings, through the integration of an innovative adaptive ventilated façade system, including:The d
eveloped technologies will be integrated in the ventilated facade, and a real time intelligent façade management system will control operation of the system based on meteorological prediction methods for forecasting in advance the decentralised electricity production and the energy (electrical and thermal) demand of the building enabling maximum RE usage. It will inter-operate with existing or latest state-of-the-art Building Energy Management System, to achieve optimum energy efficiency by reducing primary energy needs, CO2 emissions and peak loads, assuring at least the same comfort levels required by Member States Building Codes, at an affordable price.

The E2VENT system that we will develop is an external thermal refurbishment solu-tion with external cladding and air cavity (fig.1). The distinctive feature of this system is the Smart Modular Heat Recovery Unit allowing us to recover energy from the ex-tracted air while performing the air renewal using double flux heat exchanger in the air cavity (fig.2). This way the E2VENT system enhances the energetic performance of the building and fresh air renewal does not decrease it. Aiming at providing a heat storage system for the reduction of peak of electricity consumption and/or for cooling in summer, a Latent Heat Thermal Energy Storage based on phase change materials properties may be implemented if needed.

Workshop Co-Chair: BRESAER

BRESAER Introduction

BRESAER will develop a cost-effective, adaptable and industrialized “envelope system” for buildings re-furbishment. The BRESAER’s envelope (for façades and roofs) will include a combination of active and passive pre-fabricated solutions which will be integrated in a versatile lightweight structural mesh. This new technology is expected to significantly reduce the building’s primary energy consumption and the Greenhouse emissions while improving indoor environment quality through thermal, acoustic, lighting comfort and air quality at the same time. With the BRESAER system the whole building will be governed by an innovative Building Energy Management System, which will manage all the different envelope functions, the energy facilities of the building and monitor the energy generated by the BRESAER system.

BRESAER Solutions

The innovative solutions developed by the BRESAER project includes:


 Structural metallic profiles to achieve a standardized constructive system configura-ble, easy to assemble and able to support different envelope components. Such components will be fixed to the profiles with a common standardised solution allowing easy and fast instal-lation as well as removal in case of maintenance or replacement.



The innovative solutions developed by the BRESAER project includes:

Multifunctional and multilayer insulation panels made of Ultra High Performance Fi-bre Reinforced Concrete used as rigid shells for building envelope applications. Thanks to an enhanced manufacturing process they will provide insulating capacity, lightness and ease of anchoring. These can be combined with several finishes providing di-fferent functionalities: e.g. integrated PV, thermo-reflective and self-cleaning properties.




The innovative solutions developed by the BRESAER project includes:

 Combined solar thermal air and PV envelope component for indoor space heating and ventilation, thermal insulation and electricity generation. A PV film can be integrated on the air solar thermal envelop panel whilst preheated air can be used for indoor space heating and dehumidification.




The innovative solutions developed by the BRESAER project includes:

 Multifunctional lightweight ventilated façade module, with integrated photovoltaic system for electricity generation, and thermo-reflective and self-cleaning coating. Dynamic windows with automated and controlled air-tightness and insulated solar blinds. They complement energy saving and visual comfort strategies: solar blinds can automatically adjust according to the position of the sun and occupant’s comfort.A cutting-edge Building Energy Management System will be developed to measure and control both the envelope and the building’s energy consumption trough integrated simulation-based control techniques for automated the establishment of optimal operational plans.


The BRESAER Demo Site

A real demonstration is being performed in an education building in Ankara, Turkey. It consists of one building block with a gross area around 1.800 m2 (4 storeys with 450 m2 each). The BRESAER’s expected impact is to reach a near zero energy building (total primary energy consumption below 60 kWh/m2 per year) through the reduction of the energy demand for space heating and cool-ing around 30%, a contribution of solar ther-mal energy for space conditioning around 35%, and a contribution of RES for electricity generation around 10%. The estimated pay-back time is expected to be 7 years.


Additionally, 4 virtual demonstrations will be performed in buildings located in 4 other European countries covering complementary climatic zones, constructed before the Energy Performance of Buildings Directive (EU) requirements were enforced.

BRESAER impacts

Total (primary) energy consumption re-duction by a factor 2 to 4 compared to the values registered before the installa-tion of the adaptable envelope The primary energy consumption reduction will come from the integration of all the com-ponents into the BRESAER envelope solu-tion. Through the implementation of the BRESAER system, we expect to record a reduction by at least 60% of the total primary building’s energy consumption and a con-sumption of less than 60 kWh/m² Improved indoor environment The BRESAER system will improve indoor environment quality by increasing thermal, acoustics, lighting comfort and air quality (IAQ).

Demonstration of the replicability poten-tial in a real case-study The BRESAER solution will be demonstrat-ed in a real case study in an educational building in Ankara, Turkey. The building is owned by the Turkish Ministry of National Education (NME), who is also involved in the project as partner. Provide solutions with a return on invest-ment below 7 years The payback generated by the BRESAER system will be based on energy saving simu-lations taking into account future expecta-tions on market prices as well as the cost of the BRESAER envelope elements.

Validation and market uptake of active building elements Besides being validated in a real building in Turkey, the BRESAER system will be tested in 4 additional virtual demo sites. Such virtu-al demo sites are based on buildings exist-ing in 4 different European climate zones (Spain, France, Poland and Norway) with different building use. According to our esti-mates, paybacks of about 7 years are ex-pected in these countries and – by extension – in the rest of Europe.

Workshop Co-Chair: SymBIO2 Biofacades: Microalgae production in symbiosis with the building 

Invented by the architecture firm XTU Architects, the SymBI-O2 biofacade aims to provide an innovative symbiosis be-tween microalgae and buildings. Through a controlled micro-algae culture system directly integrated in specially designed facades, thermal and chemical exchanges between microal-gae culture and the host building are fully optimized. The main objectives of this project are to improve the building’s green credentials and offer an alternative and cost-effective solution to algae culture farmers.

SymBIO2 Biofacades: Microalgae production in symbiosis with the building is a  pilote biofacade, developped under a French governement funding scheme (FUI15) by the SymBIO2 consortium, has just been released near Paris, and a first commercial project led by BPD-Marignan and XTU architects, together with the SymBIO2 consortium, was the winner last February of the Reinventer. Paris com-petition for a 14.000 m² housing program hosting a 900 m² biofaçade for medical research applications.
