Flexible accommodation with energy
efficiency
A building in Germany has achieved new levels of flexibility of accommodation coupled with world class energy efficiency and low lifecycle costs, thanks to an open and scalable control system
The most modern commercial building in Germany has achieved new levels of flexibility of accommodation coupled with world class energy efficiency and low lifecycle costs, thanks to an open and scalable control system based on the Mitsubishi Electric MX4 SCADA technology The building, Einstein III, in Haidhausen, Munich, offers 37,000sqm of office and commercial space, underground car parking, a stunning central rotunda, private offices and conference facilities

Carbon reductions from combined heat and power
Combined Heat and Power (CHP) is high efficiency technology strongly backed by the UK Government, who have set a target of 10,000 MW of installed CHP capacity by 2010
With its level of intelligence, it was only natural to name it after the nation's most famous scientific son.
It is designed to be able to adapt effortlessly to the constantly changing requirements of its corporate tenants as they address new development within the markets they serve.
For Einstein III to fulfil its promise, high performance building automation technology is vital: all functions have to be integrated into one single control system in which scalability and adaptability are constant watchwords, as are comfort and efficiency.

Intelligent automation integrates manufacturing
Mitsubishi has addressed today's business needs for more flexible, efficient and integrated processes with the introduction of the iQ Platform
The technical solution was to combine MX4 the SCADA control with European Installation Bus (EIB) and Building Automation Control Network (BACNet) communications in a system that runs to every corner of the building and controls every aspect of the building environmental performance.
Einstein III has motorised external sun blinds on every facade, which reduce the internal heating/cooling load significantly.
These are controlled centrally through the MX4 SCADA system and automatically reconfigure throughout the day tracking the position of the sun and even allowing for wind effects.
The interior fittings are also designed to meet the requirements of a dynamic enterprise, which are characterised by frequent changes to the accommodation layout.
No matter what changes are made, the MX4 SCADA system can instantly adapt to provide each room - and indeed individual people - with precisely the comfort parameters they require.
To contain energy consumption the lighting system has the ability to assess and adapt to the ambient daylight levels, natural ventilation techniques are used alongside air conditioning, and presence sensors determine when unoccupied rooms can be powered down.
The Mitsubishi MX4.
These functions are controlled throughout the entire complex, as well as optimising local and background heating and ventilation, emergency lighting, security, chillers, air handling and heating circuits.
The BACNet standard has been developed as an open standard for building automation, which all builders and equipment manufacturers can adopt so that their products are all compatible with one another.
It is based on Ethernet communications and realises significant cost savings through the simplification of control systems design and implementation.
It also makes reconfiguring and extension a simple plug-and-play exercise.
During the building of Einstein III there was strict adherence to BACNet standards, so that the planning, installation and integration of the various facilities was performed to a uniform management protocol.
It is expected that future changes and developments within the building will be trouble free because of the open interoperability of the EIB and BACNet systems, and that equipment from any vendor supporting these will be easy to install.
The central MX4 SCADA system currently directly controls 6000 EIB group addresses, some of which include a significant number of local addresses which are controlled locally.
This is an efficient and flexible systems architecture which gives individuals control of their own work space climate yet allows changes in accommodation patterns to be made simply and intuitively.
During the last couple of years EIB has established itself as a prominent standard for building automation in northern and central Europe.
In order to make all data accessible to MX4 the SCADA control system, all EIB communication links are coupled via gateways to the BACnet network.
This allows each office to control lighting, temperature and other facilities locally, which leads to energy optimisation and reduced maintenance costs. Request a free brochure from Mitsubishi Electric Automation Systems ...
