Sustainable construction is rewarded with international certificates such as LEED (Leadership in Energy and Environmental Design) or DGNB (German quality seal for sustainable construction) and has become a must for future-oriented buildings.
Building sustainability involves much more than saving energy: it also covers ecological, economical and functional features for the entire lifecycle of the building from planning to demolition.
With smart installation concepts, Wieland Electric offers innovative solutions for sustainable electrical installation and automation. The distributed and pluggable design reduces cabling to an absolute minimum while ensuring all components can be recycled. This strategy helps ensures the certification objectives are met.
In the past electrical installations have often involved large, centralized distributions. Building automation solutions led to increasingly higher cabling overhead. Sustainability was not taken into account in such solutions.
smart installation means that the 3-phase power supply is routed near the consumer, leading to an improved energy balance thanks to a reduced voltage drop. Moreover, fewer cables are required, greatly reducing the amount of copper needed. The clear installation structures combined with the plug-in capability result in quick and safe installation. In addition, pluggable cables and components are reusable and offer tested industry quality. All of these benefits are enhanced even further if automation components from the subdistribution are placed close to consumers. A positive side-effect of such a smart installation concept is that installation technicians save time and money.
With an integrated product portfolio under the gesis® umbrella, covering energy supply with flat cable systems, passive and active terminal boards, pluggable, prefabricated cables as well as directly pluggable, distributed building automation components, Wieland Electric deliver proof of their leading expertise in pluggable installations. The sustainability of the smart installation concept has already been testified in numerous reference applications.
For example, Germany's first LEED Platinum certified office building "The Cube" – the new administration headquarter of the Deutsche Börse company in Eschborn near Frankfurt – is equipped with Wieland components. Also Germany's first high-rise office building with LEED Gold certification – the new headquarter of the Süddeutsche publishing company in Munich – was installed according to the smart installation concept.
Outstanding in every respect is the office area "An den Brücken" in Munich's Westend. The two completely 'green' buildings were awarded LEED V3.0 Platinum and Gold. Smart installation concepts also were planned and implemented in all areas in these buildings. The room automation is locally operated largely via battery-free EnOcean-based touchbuttons. These are detected via decentralized EnOcean-KNX gateways and transmitted to the KNX system. There, for example, the distributed gesis® EIB V blind actors and the corresponding gesis® RAN terminal boards are controlled with the modular gesis® EIB RM system. Lighting control in this project is based on the DALI system which was incorporated in the KNX system as a sub-bus system via gesis® gateways. Both the blind system drives and the lighting are directly plugged into the installation. This helped to make the installation layout very clear and easy to install. Susceptibility to installation errors was reduced to a minimum while installation speed could be increased.
