Building Automation andEnergy Efficiency



Commercial and residential buildings are places to save energy

Cities and towns account for more than 70 percent of global CO2 emissions1

Commercial and residential buildings are the largest energy consumer segment with the fastest growth in US and Europe1

More than 50 percent of the energy used for

Heating, cooling Lighting Other appliances

is electrical1

Savings of 30 – 60 percent are possible in certain applications2

The future electrical system must offer ways to reduce inefficient consumption

Optimizing supply and demandThe role of the consumer

Today consumers determine when and how much energy they want to use irrespective of the current availability

Power producers plan supplies and deliver without knowing the detailed projected consumption

Effective information exchange and automation of consumer and supplier functions can optimize the demand supply equation

For the US, a 20% reduction potential in peak demand after full deployment of demand response is estimated

The future electrical system mustfacilitate an effective dialog


Optimizing supply and demandEnergy market

Real- time tariffs are a powerful instrument to harmonize demand and supply

Tariffs are defined by Consumer demand Supply conditions Regulator intervention Competition of independent power

producers Competition of grid operators

Business management and market operations systems have to provide complete software solutions for managing energy markets

The future electrical system must provide platforms for effective markets

Smart MeteringMeter with four quadrant metering meaning that the meter can measure both imported as well as exported energy. The meter is available in versions for active energy and combined active and reactive energy

Demand ResponseHigh end user interface


HEMS balances the end-user’s comfort, cost and lifestyle preferences in the face of uncertain conditions regarding the price of electricity, weather and grid conditions

Minute-to-minute HEMS decisions include scheduling and shifting of electrical power usage

HEMS apply appropriate methods for sequential decision making under uncertainty

surPLUShomeThe Energy Concept

surPLUShomeSome technical Details - HVAC


A space saving heat pump takes care of the heating, cooling and ventilation (max. 320m3/h). It produces a maximum of 2.1kW heating and 1.3kW cooling. There is an integrated heat recovery system. The energy from the exhaust bathroom air is used for warming the fresh air intake and water heating. The heat generation level is 84%, the electro-efficiency is 0.36wh/m3. The water fro the kitchen and bathroom comes from a 180-liter hot water tank. An external 5-7kw geothermal heat pump can be connected.


surPLUShomeSome technical Details - Controlling the Building


The surPlushome has wide-ranging opportunities for individual building control. All the devices fitted in the building are networked by ABB i-bus KNX and can be centrally operated.

Too great a choice of settings would quickly overtax the user. Basic functions such light must therefore be able to be operated easily and instinctively with a switch.

Control of the air-conditioning, a view of the building‘s overall energy balance (production and consumption) as well as switching lights and music on and off are all possible using the comprehensible operating functions on the displays.

Special scenarios and detailed information about individual devices‘ consumption can also be set up.
