C. Small or medium size installations




Easy coupling to other systems

1. KNX members offer large variety of gateways to

couple to other systems

2. Examples

A. Mapping to BACnet

B. Interfacing with DALI




1. KNX manufacturers can develop own protocol

solution

1. From scratch

2. On basis of existing certified system

components from other KNX members

2. KNX is completely FREE of additional royalty

fees: No IPR royalties to be paid for KNX

standard features used in KNX certified products

to other KNX members

KNX is independent from any hard- or software technology

Electric Power Generation and Energy ConservationEnergy production and Energy saving

NEDO actively undertakes the development of new energy (e.g.,

photovoltaic, wind power, biomass and waste, geothermal power,

thermal utilization and full cells) and energy conservation

technologies, verification of technical results, and introduction and

dissemination of new technologies (e.g., support for introduction).

Through these efforts, NEDO promotes greater utilization of new

energy and improved energy conservation. NEDO also contributes to

a stable energy supply and the resolution of global environmental

problems by promoting the demonstration of new energy, energy

conservation and environmental technologies abroad based on

knowledge obtained from domestic projects.
