Energy Conservation Requirement

Buildings Use 40% of our Total

Energy Requirements

In 2030 the Global Electrical Power

Demand will be 2 x that of 2003

Increase use of Fossile energy ?

High Performance Buildings

• High Performance Buildings require Building Automation Systems

• To enable up to 30% energy savings

• To do this Sensors are required e.g. – Occupancy

– Lighting levels

– Temperature / Humidity / CO2

– Door / Window Status

Wiring: Expensive & Invasive

Conventional Wired Solutions

– Time-Consuming

– Building Mess & Noise

– Inflexible

– Invasive

– Expensive Over Building Lifespan

Wireless Transmission Considerations

• Frequency

– use license free-band.

• Range

– lower frequency, longer range.

– ensure receiver within safe range.

– take attenuators/angles into account

• Attenuators

– metal & concrete absorb/block most signals

– other materials reduce signal range

Companylogo

Problems when using Batteries

• Using batteries does result in

– maintenance

– Stocking of batteries

– Monitoring battery status

– Time /labout to replace batteries

– Waste disposal

BACnet – EnOcean Alliance Cooperation

“The task at hand is to define common implementation rules for an EnOcean/BACnet gateway,” said Dave Robin, Chairman of the BACnet Technical Working Group. “This will entail a number of issues, including specifying the network topology and the BACnet/EnOcean objectives needed to define a single model so that all implementations will be interoperable.”

“The world has evolved towards a wired and wireless infrastructure, and it is a significant step to bridge these together with a standard mechanism for building automation suppliers and users,” said Andy McMillan, President of BACnet International
