Selected research highlights from phase I (2014-2016)

In phase I (2014-2016), the SCCER FEEB&D developed new materials, components, systems and concepts with the goal to lead to a reduction of the environmental footprint of the sector by a factor of three by 2035 thanks to efficient, intelligent and interlinked buildings.

The research activities were focused on high performance insulation materials, advanced glazing and use of daylighting, integration of renewable energies in buildings, efficient operation of buildings and their integration into local multi-energy grids. To complete the holistic approach, socio-economic issues related to the implementation of these new concepts in practice were addressed as well.

While the focus in phase I was mainly the development of new solutions and their validation in the areas described above, more and more emphasis will be given on implementation and optimisation in phase II (2017-2020).

WP1: Building Envelope

The overall energy demand for space heating should be reduced by 39% by 2035 compared to 2000 and for lighting a reduction of 41% is envisaged. This creates the need for new materials and components with improved properties to be used in the building envelope.

WP2: Building Energy Management

The total final energy demand per square meter for the operation of buildings (heat and electricity) should be reduced by a factor of two by 2035 compared to 2000. The reduction of the basic energy demand thanks to more efficient building envelopes is a first step. The second step requires active building energy management and smart control strategies in order to make maximum use of the en- ergy supplied to buildings.

WP3: Urban Decentralized Energy Systems

The goal of decentralized energy systems with respect to the energy strategy 2050 was to achieve an effective use of local renewables and waste heat resources as well as an efficient energy management including supply, distribution, storage, and consumption within districts of various sizes. The aim of considering a district instead of individual buildings was to increase the overall efficiency performance by achieving synergies between the differing behaviours of individual buildings and to reduce the overall investment costs. In this way a district can either have a net zero energy balance, or provide energy services to the wider region or to other decentralised energy systems (DES), respectively. The holistic integration of such DES into the overall Swiss energy system is expected to reduce the total final energy demand and CO2 emissions for Switzerland.

WP4: Market Diffusion and Implementation of Technologies

WP4 evaluated how policy makers and business actors can accelerate the development and adoption of SCCER FEEB&D technologies. The timely diffusion and implementation of innovations is essential for achieving the goals of the Energy Strategy 2050. WP1 to WP3 evaluated the potential contribution of technological innovations such as aerogel insulation, building integrated photovoltaics, dynamic glazing, active building management, or urban energy hubs, to the Energy Strategy 2050. At the same time WP1 to WP3 identified predominantly non-technological barriers, such as the uncertainty about the economic performance of technologies or the resistance to change by consumers, firms, and energy suppliers, as major barriers for the development, diffusion, and implementation of SCCER FEEB&D technologies.
