Aventa AS (Norway)

Aventa AS is a private-owned, Norwegian R&D and industrial company focusing on solar thermal collectors of polymeric 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. NorDan Solar is a collaboration between leading actors in Scandinavia, NorDan, OSO Hotwater, Uponor and Aventa.

Aventa’s contribution to Task 56 is NorDan Solar, a new facade envelope system, where solar thermal collectors are integrated in windows as pre-fabricated facade units. The concept is a considerable step forward to demonstrate esthetic integration of ST into the facade, overcome existing installation barriers and reduce overall costs at the building site. The availability in various dimensions, simple, non-pressurised hydraulic design, using standardised plug-and play components, which are well-known to installers, together with appealing design aim to remove the barriers, which ST technology meets today.

Eindhoven University - Department of the Built Environment  (The Netherlands)

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, is our main contribution in Task 56. Relevant projects include collaborations with e.g. Wellsun, ZigZagSolar, SEAC and Merck Window Technologies.

The Institute for Renewable Energy of Eurac Research will contribute to IEA SHC Task 56 activities with the project SunRise. The aim of the project is 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 will allow sharing knowhow with the Task 56 participants, is 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.

Lund University (Sweden)

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 contribute 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 is being carried out. The main participants are the University, a large Swedish contractor (NCC) with close support from a broad and experienced industrial reference group.

The department offers special expertise in the following areas:
• Building materials and construction
• Energy and environmentally responsible buildings
• Architectural history and theory
• Transformation - preservation and development

The main contributions to the Task 56 will be the research results in connection to the partner project Advanced building skins with integrated technology – SkinTech. The research tasks carried out will be 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 will be user comfort, mountability, end-of-life treatment (recycling), control and global optimization of systems. In addition, the project aims at demonstrating the feasibility at whole building scale and assess the performance of the advanced building skin solutions developed. The evaluation of the integrated building skins will be carried out by data collection and monitoring of full-scale buildings. User-interaction and acceptance of developed products/systems will be an important aspect to be considered when it comes to real applicability of highly technical solutions.

Innsbruck University - Unit of Energy Efficient Buildings (Austria)

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 are developed in the project SaLüΗ! which allow 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 will investigate by means of simulation the potential of using the façade integrated MVHR and HP for cooling and how the potential of coupling this ventilation heating and cooling system to PV in terms of the self-consumption and non-renewable primary energy reduction.
