Architecture & building technology
Buildings must first and foremost meet the needs of their users. To this end, they can be adapted to suit the exterior climate and the varying user requirements by providing suitable glazing, facades and systems for air and heat management. Clever building concepts and innovative building systems provide the necessary flexibility for this. However, today’s and, in particular, future buildings are not closed systems. In future, buildings will interact more closely via energy systems with other buildings or energy suppliers. As elements in larger networks, buildings have energy interfaces with neighbouring buildings, districts and electricity and heating networks.
Solar-active building envelopes, high thermal insulation and energy- and exergy-optimised building technology enable energy-plus buildings that generate more energy than they consume in the annual balancing. This allows them to take on a more interactive role as grid-supportive buildings in conjunction with the future renewable electricity grid. In future, this will enable excess solar and wind power to be used and stored in a highly efficient manner in the form of heating and cooling energy in buildings.
In many demonstration projects in the new-build and refurbishment sectors, different technological innovations and new systems and concepts are being tested in practice and the resulting building performance and the effects on the energy system scientifically evaluated.
