2 The Concept In the same way as we today know the fuel consumption of our car, will we have to be able to answer the question, What is the energy consumption of your building per square meter? in the future. From the corporate brochure of a major energy supplier Almost 4 percent of the total energy consumption goes into buildings. Above one-third is used for space and water heating and the rest for cooling, ventilation and artificial lighting. Simple mathematics show, and society broadly agrees, that the use of fossil fuels needs to be reduced and eliminated on the long term. Energy efficiency and conservation in public and private buildings will therefore be more and more important on the medium term. However, economics is not the only reason. Improving energy efficiency in buildings is one of the key measures for tackling energy supply and environmental problems and reaching our CO 2 reduction targets by 22. The statutory and regulatory framework has been established by the European Parliament (EN 15232) and by the German federal government in the form of the Energy Conservation Regulations (EnEV) from 22. These regulations define the evaluation guidelines to be used in drawing up an energy balance sheet for residential buildings, including technical systems. The 27 edition of the EnEV regulations extends its scope to non-residential buildings and makes energy certification a requirement for existing buildings. EnEV 29, effective since October 1st, 29, has tightened up the energy requirements for buildings by 3 percent, with a further 3 percent tightening planned by 212. As the Scottish physicist Sir William Thomson, later Lord Kelvin, once said, If you cannot measure it, you cannot improve it. Only if you have the ability to capture, analyse and evaluate your energy consumption data on the long term you will have a chance to identify potential savings and to introduce appropriate conservation measures. To make this happen you need to bring all your energy-related data together in one central platform. Benchmarking for a wide variety of building types and uses (e.g. including hotels, hospitals, schools or office buildings) helps to take action for a better level of energy efficiency. Finally, we have to invest in the energy assessment of our living and working spaces to know the specific energy consumption. As we are aware of the fuel consumption of our car, we have to be able to give the answer to the question: What is the energy consumption of your building per square meter?

3 > e3m > makes energy consumption transparent is the professional solution for analysing the energy consumption of your property. Choose from a selection of standard reports, or use the intuitive interface to make customised data queries. e3m processes the raw data to generate key figures. Thanks to a powerful database engine, coupled with web technology, the data is available anywhere at the touch of a button. > shows potential savings e3m is the core component of a continuous optimisation process. Its complex statistical analysis capabilities gives you a choice of comparative options using benchmarks, direct comparisons or long-term analysis. Using this technology, e3m users can save up to 4 per cent in energy costs. is flexible and modular e3m is much more than just capturing data it offers built-in alert functions, tenant modelling, local visualisation, on/off timer programming and more. e3m is available both as a classic on-site installation and as an online service. It s your choice whether to buy a conventional licence or take the Software as a Service option. > is scalable and open e3m is well suited from single use in one office building to distributed applications for property managers and chain businesses. e3m allows open integration of external systems at both individual property level (DDCs and building control software) and centrally (asset and facility management software).

4 Technology and Modules e3m is a scalable energy data management system, which can be deployed either as Software as a Service or locally as a system solution. It enables you to centrally manage and analyse meter data, key figures and reference values for your properties at local, national or global level. As a result, you ll be in a position to create a continuous information flow, from data capturing through to financial accounting. Your web browser is the universal frontend for e3m. Thin Client Technology gives you access to all data and configurations in the e3m Data Center from any location. Features/Modules: Display and configuration of e3m Data Center Managing and monitoring the e3m portal Support for clients and multi-language applications Universal frontend for all e3m data Displays on a variety of hardware, from PDA to laptop or desktop PC Data transfer: TCP/IP connection of your choice Encrypted via SSL connection Web 2. AJAX technology The e3m Data Center allows you to centrally manage the relevant key figures for your properties. This is where all the data comes together. It lets you perform various analyses covering everything from process optimisation and energy management to maintenance and repairs. Features/Modules: Capturing, storing and processing data Overall alert and fault management Management of metered and reference values Manual entry of meter readings Data verification and correction Location and tenant management Document management Automatic data aggregation Load profile management Key figures, e.g. electricity or heat consumption by area, CO 2 emissions by area Benchmarking and energy certification Analysis and reports Centralised version and user management

5 The e3m Box is a maintenance-free on-site hardware solution for handling meter readings. The meter data is processed in the e3m Box and transmitted to the e3m Data Center. The e3m Box can be expanded from a smart data aggregator to a complex, web-enabled building control system tailored to project-specific requirements. Features/Modules: Scalable (up to 5, data points) Data buffer in case connection is lost (SQL database) HMI/SCADA online visualisation Alert management Diagrams, tables and reports Process charts On/off timer programming IEC SoftLogic Data transfer: TCP/IP connection of your choice (XDSL, GPRS, UMTS, ISDN, etc.) Encrypted via VPN connection Integrates with: BACnet/IP (Siemens, Sauter, Honeywell, Johnson, TAC, Priva, SAIA, etc.) MBus (Relay, Aquametro, etc.) Modbus TCP/IP (Wago, Saia, Beckhoff, EnOcean, etc.) KNXnet/IP (ABB, Siemens, etc.) Danbus (Danfoss) Wurm IP (Wurm) Elreha (Elreha) Other systems on request e3m Connector is a software service used to integrate the system with existing software systems on site.

8 > The Logo The idea for the logo came to us quite naturally in an attempt to define the concept of energy management. A management process consists of four phases: goal setting, planning, implementation and review. So what has to be considered? Environment Energy It s all about energy and using it in a responsible way. That implies that beside the economic aspects, the environment also has to play a role. Reduced CO 2 emissions are not only good for the environment; they also have clear financial benefits. It s an undisputed fact that environment-friendly energy is the energy we don t consume. Energy efficiency means achieving a desired benefit with the lowest possible energy input. The three concepts energy, environment and efficiency appear in our logo as the subject of the management process.
