LIGHT+BUILDING
Buildings as power stations Light & Building presents a vision of the future
Buildings account for around 40 percent of total energy consumption and therefore have an important role to play in the new energy paradigm.
world’s biggest trade fair for lighting and building-services technology - revealed the opportunities offered by intelligent and networked buildings when over 2, 352 exhibitors from 50 countries presented their latest products and trends for the fields of lighting, electrical engineering, home and building automation and software for the construction industry. In addition to the
H
comprehensive spectrum of products and services, the 196,000
eld on the 15 to 20 April in Frankfurt, Light+Building - the
visitors to the show were also able to experience a special exhibition entitled ‘Buildings as Power Stations in the Smart Grid’ – this showed how networked buildings generate, store, distribute and use energy on a decentralised basis. The driving force of a new
energy policy is the European Union with its European Building Performance Directive (EBPD), which lays down a zero-energy standard for new buildings in 2021. In Germany, the Renewable Energy Law and the corresponding law for heating promotes the generation of energy on a decentralised basis. It is only possible to compensate for the closure of atomic power stations through decentralised, regenerative electricity generation. These sources of energy fluctuate and therefore need a certain storage capacity to guarantee the power supply at all
times. And buildings can make a considerable contribution to this. To achieve this target,
buildings must become significantly more efficient and produce a larger proportion of the energy they need instead of depending on large, central power stations. This means that buildings must be equipped with their own energy generators, storage units, management systems and protective tech - nology. Additionally, energy-using equipment and the networks must be linked so that the smart grid knows where and how much power is required, as well as how much can be generated so it can har monise demand and supply on a regional basis with other power users and suppliers. Hence, it is important not only to reduce consumption in smart buildings but also to ensure optimum power generation, storage and links to the network. Organised by Messe Frankfurt,
with the support of the German Association of the Electrical and Electronics Industry, and implemented by the renowned firm of con sulting engineers, Canzler, the ‘Buildings as Power Stations in the Smart Grid’ exhibition showed visitors to Light+Building a residential dwelling with photovoltaic and wind-energy systems, a roof designed for walking on and a filling station for electric cars. The installations, some of which were shown in live operation to visitors, all used products and components available on the market, for example photovoltaic and wind power, combined heat and power generation, fuel cells and storage technology, all kinds of storage methods, transducers, meters, switching and protective modules, installation technology

including networking and integration, as well as visualisation and operating units. Within the framework of the
Building Performance Congress, expert speakers also offered visitors to Light+Building an insight into state-of-the-art technology, providing information about planning and the optimum design of smart buildings in the Technology Forum. Topics covered included the modernisation of existing buildings and designing and planning modern functional buildings. And running in parallel to the
exhibition was a special show entitled ‘The E-House – Intelligent buildings by professionals: energy efficiency, comfort and security.’ Housed within seven rooms, this 100sqm model house shone a spotlight on networked building- services technology, LED lighting, concepts for technology-aided homes for the aged and the use of self-generated electricity from regenerative sources. During the evenings after
Light+Building, trade visitors and the citizens of Frankfurt had the chance to enjoy another highlight – Luminale – a spectacular series of illuminations that transformed locations in Frankfurt and the region into fascinating worlds of light. Over 140,000 visitors from all over the world were transfixed by the 170 lighting installations in Frankfurt and several other cities
in the region.
The next Light+Building will be held in Frankfurt am Main from 30 March to 4 April 2014. For more information visit
