Buildings are the major energy consumerover their entire life cycle

Energy accounts for 40% of the building operation cost**

Lighting Building automation and control systemsChillersHeating boilers

Modern heating boilers achieve fuel savings of up to 40%

Compared to low-temperature boilers, the combination of condensing boiler and solar plant reduces fuel consumption by about 30%

Modern chillers require only about 50% of the energy consumed by old centrifugal machines

Running on alternative fuels (e.g. natural gas) when electricity prices are high

The life expectancy of energy-saving lamps is about 15 times that of conventional incandes-cent bulbs, of LEDs about 50 times and using about 80% less energy

If 30% of all incandescent bulbs were replaced by energy-saving lamps worldwide CO2 emissions would drop by about 270 million tons p.a.

The systems ensure demand-dependent control and management of all technical building systems while giving consideration to the building‘s usage requirements

Advanced building automation and control systems offer energy savings of 20 to 40%(3)

Small, light installations

Easy to install on roofs

Produce up to 10,000 kWh p.a.

Produce enough electricity for 2 low-energy houses or one office with 20 workplaces

50% efficiency

50% increase in solar heat in Germany in first half of 2008

Cristalline silicon solar modules convert 13 to 18% of solar energy to electrical power

Thin-film solar modules have efficiencies of 5 to 8%

25% energy is required to produce 100% heat output

38% less CO2 emissions compared to gas heating, and 57% less compared to oil heating

Only 40% of operating costs of a typical gas heating system

In 2007, co-generation plants in Germany produced 21 GW (12%) of all electrical power generated

In Germany, the potential of co-generation plants that could be economically used amounts to about 57% of all electrical power generated

Bio co-generation plants produce 70% less CO2 than conventional power plants (5)

Operating cost are mostly growing over time

Operating costs are reduced over first 6 months with immediate measures

During teh continuous optimization phase we identify additional improvement measures

The yearly service fee is always smaller than the customer value

After the first 2 years we reduce the service fee (better knowledge of the building)

It is possible to have a success based service contract!

Demand Side ManagementEnergy efficiency & Demand Response

- Low adoption rates- CAPEX intensive

Dispatchable& predictable

-Non Dispatchable


Demand Response – Types and Comparison

Desired results are slower to achieve since it is linked to direct response from consumers

Sustained awareness necessary to reach targets

Not predictable depending on the customer base

Transparent incentive for participation

More popular because consumers are paid each month regardless of whether DR event is called or not

More active tool for load serving entities, utilities or grid operators to manage costs and maintain reliability- minimises brown-outs/blackouts, savings in building additional infrastructure

Incentive-based

SEMI-AUTOMATED-Controls for load-shedding- Person initiates pre-programmed strategy through BMS


Siemens Demand Response OfferingBenefits

e.g. A customer sets their air conditioning unit such that it automatically either switches

off, or raises its set-point if the market price rises above a

certain trigger point.

e.g. The utility signs a contract with a building owner that

allows the utility to dim lighting in the building at times of

peak demand. The signal is sent directly to the lighting

control system in the building and is executed without

intervention.

e.g. A Critical Peak Pricing (CPP) event is called that sets the energy price at a premium

for a period of the following day. Customers manually adjust their consumption to avoid the expensive CPP

period.

e.g. The utility signs a contract with a large industrial

customer that allows them to call on that customer to shed

load a number of times a year. The load reduction itself is executed manually by the customer in response to a phone call from the utility

Demand Response - Balancing Needs & Desires


Demand response can be used to…

Manage system peaks that threaten supply-demand balance

Manage local congestion

Minimise power procurement costs

Market conditions occur that raise supply costs

Provide ancillary services to the transmission operator

Our Demand Response Management System receives a load shed notification from a utility or

wholesale market

Our Intelligent Software Aggregation Engine acknowledges an event is being called

Within 1 minute of initial dispatch, load begins to ramp down at commercial and

industrial sites

Our Aggregation Engine relays signals toonsite communicators and notifies the

facility operator simultaneously

Siemens high-tech approach facilitates reliable participation in short notice programs, generally offering a higher incentive.

Due to our real-time visibility and our aggregation engine, Siemens is able to shield the load provider from penalty risk.
