Acquire your energy consumption data –manage cost reduction !

e3m Energy Management:acquire | verify | optimise | manage

Almost 40 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

reduction targets by 2020.

The statutory and regulatory framework has been established by the European Parliament (EN 15232) and by the German fed-eral government in the form of the Energy Conservation Regula-tions (EnEV) from 2002. These regulations define the evaluation guidelines to be used in drawing up an energy balance sheet for residential buildings, including technical systems. The 2007 edi-tion of the EnEV regulations extends its scope to non-residential buildings and makes energy certification a requirement for exist-ing buildings. EnEV 2009, effective since October 1st, 2009, has tightened up the energy requirements for buildings by 30 per-cent, with a further 30 percent tightening planned by 2012.

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 en-ergy consumption data on the long term you will have a chance to identify potential savings and to introduce appropriate conserva-tion measures. To make this happen you need to bring all your en-ergy-related data together in one central platform. Benchmark-ing 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 con-sumption of your building per square meter ?’

“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.”

The Concept

Branch Zürich[Switzerland]

is scalable and open>

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 40 per cent in energy costs.

shows potential savings>

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 flexible and modular>

makes energy consumption transparent>e3m 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 cus-tomised 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.

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 sys-tems at both individual property level (DDCs and building control software) and centrally (asset and facility management software).

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 ma-nagement to maintenance and repairs.

Your web browser is the universal front-end 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 2.0 AJAX technology

e3m is a scalable energy data management system, which can be deployed either as Software as a Service or locally as a system solu-tion. 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.

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

e.g. Alert, MobiCall, ixArma)• AMS (projects, costs, maintenance,

e.g. IBM Maximo)• ERP (costs, consumption, e.g. SAP)• CAFM (spaces, metrics, tenants,

e.g. Aperture)• Billing (cost centres, incidental costs,

e.g. XAP)

The e3m Data Center performs the de-manding task of delivering information to every user, for every application, in every location.

Facts and figures:• 130 branches• 120,000 data points• 50 users• Interface with ERP system• Annual energy costs > CHF 30 million

Initial Situation:• Manual meter reading and analysis in Excel• Excessive energy consumption detected month later• Operations and systems optimized on site only• Laborious billing of internal cost centres and tenants• No direct view on data (energy consumption,

temperatures, etc.)• No centralised alert monitoring of energy consumption

and technical systems• Retail space in 2002: 183,895 m²• Retail space in 2008: 215,080 m²

Case StudyMigros is Switzerland’s biggest retailer and also has branches in southern Germany and France. The Migros group comprises over 50 busi-nesses and is a cooperative with approx. two million members. In 2008 the group employed over 84,000 people and reported sales of CHF 25.75 billion and profits of CHF 701 million. The e3m energy management solution was introduced across the board in two of the cooperative businesses. Inside Migros e3m technology is known as MESA.

Efficiency

Management

– 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 ?

It’s all about energy and using it in a responsible way. That im-plies 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.
