CHAPTER 6

●

Examples of Lossnay Applications

2.5 System trends

●

Creation of an environment including independence, management and control of each zone can be realised as work trends
become more diversified.

●

Simultaneous cooling/heating system due to necessity from increased fixed sash windows and increase in office automation
systems.

●

Attention is being paid to building management methods which manage not only air conditioning systems for several
buildings at one location but also manage other information.
