The Building Performance chair at Eindhoven University of Technology aims to contribute to achieving a sustainable, energy-positive built environment with indoor environmental quality optimized for health, comfort and/or productivity. This requires a multi-scale/ multi-physics and trans-disciplinary approach that addresses technological solutions for energy generation, storage, distribution and demand reduction, and integrates and optimizes these in design, construction and operation of new and existing buildings.
A variety of new ideas for more effective collection and utilization of solar energy in the building shell has recently been proposed. However, it turns out to be far from trivial to make the step from innovative R&D project outcomes (e.g. prototypes) to commercially successful building products that make real contributions to achieving sustainability targets. TU/e is working on the development of new computational methods as an enabling tool in such transitions. Sharing these developments, as well as learning from the experiences of others, was our main contribution in Task 56. Relevant projects included collaborations with e.g. Wellsun, ZigZagSolar, SEAC and Merck Window Technologies.

Their activities include national and international research projects, as well as direct cooperation with industry partners. Industry-related projects normally involve the development of new products and the evaluation of technological solutions. The Institute also supports the promotion of renewable energy technologies and assists political decision-makers through their scientific consultancy.
The Institute for Renewable Energy of Eurac Research contributed to IEA SHC Task 56 activities with the project SunRise. The aim of the project was to design and develop advanced two solar façade systems particularly suitable for covering heating, cooling and hot water demands of typical office buildings. With respect to the first concept, solar-thermal energy is harvested through solar collectors, stored in a façade integrated water storage and distributed through a radiant heating system. In the second concept, a compact and modular AHU is developed and integrated in the opaque portion of the façade delivering heating, cooling and fresh air. A second study, which allowed sharing knowhow with the Task 56 participants, was the H2020 project BuildHEAT, where integration of PV and solar thermal into multifamily houses’ façades is tackled by developing and demonstrating a multifunctional anchoring system.

Inaventa Solar is a Norwegian solar energy company on track to industrialise and commercialise innovative solar collector technology. The company offers a new solar heating concept based on cost-effective and architecturally appealing solar collectors in high-performing polymer materials for building integration. Through the collaboration with leading building construction companies the installation of the solar heating system should be a part of the overall building process, saving time and costs.
The shift from metals to new materials such as polymers and ceramics is seen across many sectors, including automotive industry, aviation, consumables and construction. A reduction in weight and chemical sustainability is a key benefit of such a shift; as is the fact that large-scale industrial processing techniques have already been developed for polymeric products. Solar collectors of polymer materials can be produced in continuous processes and easily be adapted to a variety of dimensions and to customers’ requests. A new facility for the manufacturing of solar collectors is under construction to expand production capacity and realize the potential of the technology. In 2019 the technology has been taken over by Inaventa Solar (formerly owned by Aventa).
One joint demonstration project together with Cenergia/ KUBEN Management in Task 56 was the so-called Living in Light Box in Copenhagen, Denmark, a CO2 neutral "Active House" test-housing unit demonstrating innovative Active Roofs and Facades technologies.

Buildings account for 40% of the total energy use in Sweden. Due to its strong links to environmental impacts, it is a central goal of the society to reduce energy use within the sector of residential and commercial buildings. Our work focuses on aims and means to create energy-efficient buildings, for example by insulating buildings well, and to utilise solar energy and daylight and to use solar shading devices to protect against unwanted solar gains. Effects of various building designs are studied regarding energy use (both for heating and cooling) and thermal and visual indoor climate.
We contributed to this IEA task with an ongoing project on renovation of Swedish multi-family buildings by using pre-fabricated multifunctional façade modules with integrated systems for ventilation, heat recovery and renewable energy. A feasibility study (technology mapping, architectural criteria, energy and financial calculations) and concept development of the above facade elements was carried out. The main participants were the University, a large Swedish contractor (NCC) with close support from a broad and experienced industrial reference group.

The main contributions to the Task 56 were the research results in connection to the partner project Advanced building skins with integrated technology – SkinTech. The research tasks carried out were dedicated to advanced building skins in sustainable building concepts with focus on energy performance analyses and holistic building design approaches that are not usually considered for "traditional" facades. Further assessment criteria were user comfort, mountability, end-of-life treatment (recycling), control and global optimization of systems. In addition, the project aimed at demonstrating the feasibility at whole building scale and assessed the performance of the advanced building skin solutions developed. The evaluation of the integrated building skins was carried out by data collection and monitoring of full-scale buildings. User-interaction and acceptance of developed products/systems were an important aspect to be considered when it came to real applicability of highly technical solutions.

The Passive House Institute (PHI) is an independent research institute with a continuously growing interdisciplinary team of employees. PHI has played an especially crucial role in the development of the Passive House concept. The first pilot project (Darmstadt, Germany, 1990) was Europe’s first inhabited multi-family house to achieve a documented heating energy consumption of below 12 kWh/(m²a), a consumption level confirmed through years of detailed monitoring. Since then, the Passive House Institute has assumed a leading position with regard to research on and development of construction concepts, building components, planning tools and quality assurance for especially energy efficient buildings.
The Passive House Institute is constantly developing and improving upon algorithms and software tools for dynamic building simulations, the determination of energy balances and the planning of Passive House buildings (for example, through the Passive House Planning Package). The Institute acts as an independent testing and certification center for buildings and building components such as wall and construction systems, windows, doors, connections, ventilation systems and compact systems. PHI research staff also provide manufacturers of energy efficient components with in-depth consultancy on product development and optimisation.
As part of Task 56, PHI has developed a predesign tool based on simplified algorithms. This enabled to optimize a design and integration of products into the facade during the planning phase. The tool allowed evaluation of the energy performance of a building equipped with a solar envelope systems.

The Unit of Energy Efficient Buildings at UIBK represents a link between classical civil engineering in the building sector, the more mechanical engineering driven HVAC system and the use of renewable energy (solar, biomass, ambient heat) in buildings. The main tasks are supporting the sustainable renewal process, both through the training of competent engineers and architects, as well as through research and development for the benefit of human health, sustainable development and the protection of the environment.
Experience shows that for multi-family houses, a complete renovation including conversion to central heating and DHW systems is hardly possible. As energy and cost efficient decentralized solutions are not available (EU-project Sinfonia) new innovative concepts for heating and ventilation are under investigation. Very compact heat pumps were developed in the project SaLüΗ! which allowed the integration into the window parapet or into a prefabricated timber façade with a high potential of prefabrication and as optimal solution for small apartments. Within Task 56 UIBK investigated by means of simulation the potential of using the façade integrated MVHR and HP for heating and cooling. The potential of coupling this ventilation heating and cooling system to PV was investigated regarding the self-consumption and non-renewable primary energy reduction. Simulation studies were performed to evaluate BISES on building level using virtual case studies of residential and non-residential buildings. Furthermore, (pre-)design tools such as PHPP and DALEC were further developed. Fabian Ochs of UIBK was leading Subtask C of IEA SHC Task 56.
